I am officially learning Docker and K8S starting today and re-watching this gem for the Nth time to hype me up. You never fail to inspire me, Sir Chuck.
I used to skip over your videos on my home feed because they were always so long and telling me I NEED to do stuff. But I've just been binge watching your stuff all weekend. Learned so much so far.
Docker is one of those things that I was aware of but never really looked into. After watching, this I realised what I had been missing out on and spend the next few hours learning more. Great content - Thanks.
Hi Chuck, I found your channel just yesterday and have been watching it non stop ever since. I am a big linux fan, have been using it since 2006 ,however I have no formal education in this field .I Just Like it and always have. I also have tried so many distros and love testing new ones. Btw Im 59 years old and thinking of taking one of these courses you recommend to actually learn this properly. Thank you for the inspiration. I absolutely love your style of teaching ,sense of humour and your passion for this shows on every video.
The name ESX originated as an abbreviation of Elastic Sky X. In September 2004, the replacement for ESX was internally called VMvisor, but later changed to ESXi (as the "i" in ESXi stood for "integrated").
Chuck-this was seriously one of the best videos I've seen. You kept it high-level enough to keep the concept itself in focus. Thank you thank you thank you!!
Dude I've been in IT my whole life and could probably teach all this stuff if I were so inclined but I just love watching your videos, your enthusiasm is infectious and honestly even though I've been working with these systems my whole life I feel like I come away from your videos knowing a bit more. Never stop learning!
What, I never knew that! I started using vmware software in 2007, an application called GSX. That only ran on windows. Then I was introduced to ESX version 2.5, I remember that ESX 3 was released but everyone was saying not to use it. Then we upgrade from 2.5 to 3.5.. this whole time I never heard what esx meant. I was told years ago ESX was the enterprise version of GSX..
Having watched only your videos for the past two weeks I went from "I hate networking" to "holy shit the possibilities are endless this is amazing" and now got a full homelab and a server almost ready for the small business I work at. You target such precise interrogations I had about how network and server work, it's a great complement to my knowledge that was up until now only on the desktop side of linux, Thanks!
Okay, this is one of those videos where you did everything right. Before I watched your video I didn't know how Docker works, now I understand. Very well explained. Thank you.
I am at 2:12 right now and i saw this guy fetch one of the servers i guess from the data center for the purpose of this video.I know that i can't touch that but what i can feel is his true effort for this content.Nothing can describe what a VM is better than having a server thing like this IN HAND.Salute to you and to ur efforts!
I'm still making VMs. I've been planning to 'learn containers' for several years. I never knew it was so simple. I'm going to start testing this out immediately. Thanks for such a brief and convincing presentation.
Let's correct a little thing: Docker, Container and Images. A Docker image is a file, comprised of multiple layers, that is used to execute code in a Docker container. An image is essentially built from the instructions for a complete and executable version of an application, which relies on the host OS kernel, whereas Docker Container is the instantiation of Docker Image. In other words, Docker Container is the run time instance of images. Docker is basically a container engine that uses the Linux Kernel features to create containers on top of an operating system. So everytime you pull an OS via Docker, you pull the image. When you run it, you create a container. :) I like your channel. Keep doing things like you do! Best regards
When you virtualize a system like your example at 3:46, you can do over-allocation. Meaning that 1 VCPU is not equal to 1 CPU (hardware) or 1 GB RAM (hardware) is not equal to 1 GB VRAM. Around 17:49 you explain this odd. Today, people run a hypervisor and then put a container. For your example with Ubuntu running on a server. We would just create a VM running Ubuntu and run X docker images from that. Hence you would use Windows 2016 as a VM and run Windows Docker Containers. Space is trivial, It cost NOTHING in the overall picture. We don't really care so much about the compute or data cost within a data center anymore. Hence you can see this in the code of a lot of software. It just consumes EVERYTHING it can. If the code was written to be more efficient, we would use less virtual hardware for that workflow. A docker container over 1 GB can be considered large and yes you can spin it up fast, but I can do the same with a virtual machine. What is faster? I see it time and time again. One compares Hypervisor to containers. This is not how the world works anymore. Yes, the VM will take up more resources, but does it really? Your docker-engine just bricked a full 64 GB 128 RAM server. Well, the Hypervisor can do what I have explained above. Allowing you to add docker control planes as you want, but still use VM when you want. I don't know why people keep saying. 1 VM can only use 16 CPU and 40 GB RAM and never can be downsized. That is simply not how the world works anymore. I can scale up and down all day with a VM. I don't think one should compare them. I think this is a common issue in the tech industry. VMs and containers should not necessarily be seen as rivals. Rather, you can use both to balance the workload between the two. VM works 100% of the time, but you can really overcomplicate containers. You will need 100 add-ons just to monitor it correctly. Edit-- Been reading some of the comments in this video. Why are people not using SLA backend cloud services?
Wrote the same. Containers complement virualization, and it will never replace it. That machine in the cloud that runs docker....guess what...its a vm.
Man, you're amazing. You made a straightforward way to explain docker. I have been trying to understand for 100 years, and no one has the same way. Thanks a lot for all your efforts and all videos you're making for us
It's so easy to refund a credit card I don't understand why people are so afraid to use them. I wouldn't use a debit card because that gives people access to your money, but credit cards are very safe.
privacy.com can help you with that. Your real card information is never exposed to the company you need to use. They use ghost cards to make transactions, check it out!
Finally- after months of trying to understand docker, you sum it up perfectly. Yes, more videos, please. BTW- How did you do the graphic overlay? Was it live or did you record it and add the overlay in post?
What I assume he's doing is recording the screen that he's "drawing on". Then he takes that screen recording and places it over the video, probably key-ing out the background of the screen recording so that it is transparent.
My Best guess: He is drawing on Adobe Photoshop on a grey background + Screen records it. Later, he syncs the drawing with the video and removes the background easily (as it is all a single color). This probably means he can't use grey in his drawings, so if he ever does, I got sth wrong.
He has a studio tour video and in the first 10 mins he explains how he draws with a wiacom tablet onto a photoshop green screen which is keyed in onto his video. This can be done in live streaming as well
I wish I’d understand what’s in it for me 🤣. Not a Dev, not an IT guy, just a computer enthusiast, I found your channel while looking at pfsense tutos . Your delivery is top notch, I watched it all. Kudos.
@@fullstack_journey I am aware. I was just stating that the progress was extremely recent (because of the video's release date). As for the experimental part, I actually downloaded docker last week, and the WSL2 support is still called experimental in the settings. It is turned on by default though.

Thank you. I am from China. I got 500K job in LA by watching your videos. Buying a huge house in LA 6 months ago. Life has been great after escaping China.
@@norpriest521 In a "explain like I'm 5" kind of way... it's like a VM in a way but it's not. You can run containers that will appear to be other physical machines on your network, you can run them on one machine and just have that machine handle everything. Whatever you want. It's hard to explain, which is why I stayed away from it for a long time... but then I started using it and holy shit, it's SO USEFUL. Personally, I'll just stand up a VM and then use Docker to run whatever containers I want (just think of them as little VMs of sorts, even though they're not VMs by definition). Media server to stream shit to my TV/computer/FireStick/etc, DNS, SMB, Git repos, whatever. And if I ever wanna move a container to another machine, it's a matter of minutes (copy my Bash script, point it to the "volumes" as needed, run it, done). Couldn't recommend it enough. It's one of the most ridiculously useful things to anybody in IT, it's FOSS, it's *stupid* easy to work with, etc. And to me, the best part is I can stay the fuuuuuck away from dependency hell. Docker will run on damn near anything so you just get it up and it'll handle all the rest. Not having to worry at ALL about unfucking dependencies left and right on a complicated system is absolutely amazing. 10/10 would recommend.
I have been to several Universities around the Middle East and Eastern Asia I wish I had professors and teachers like you You have the rithme Thanx a lot
Sitting here looking at all my VMs I have in production after watching this video and thinking to myself what have I been doing with my life?!? Great video, Chuck! One of my favorite CBT Nuggets trainers.
Depending on what type of applications you run, such as Java or Spring, putting things in Docker can be as easy as creating a Dockerfile and piping your output into a container. .Net is a different beast. However, you CAN run straight Docker in a Prod environment if you want, but it's honestly best not to. I manage about 15 Kubernetes cluster for my company, all running .Net Core apps running in Docker containers. Little by little, we're taking apps off VMs and deploying then in K8s.
And if you run docker on WIN10, it will activate "Hyper-V" function which mean if you like to use virtualbox or VMware(don't know about others) it will end up in error. Hyper-V doesn't like other hypervisors very much.

I have been told once that "You CAN'T RUN A CONTEINER AS A VIRTUAL MACHINE", what I always though was possible, because a container is "an OS with embedded applications". Thanks to you video, today I know THEY ARE WRONG! Thanks Chuck! Building my own home-lab with LOTS of improvements thanks to you channel!
Hi Chuck, i never post comments but you're video is too awesome not to comment upon. Love the fact that you got a real server, opened it up etc etc Seriously cool and excellently presented, thank you!
this is exactly what I have been searching for. I am a senior manager and not a developer and couldn't fully understand the other mechanical docker videos. thanks for creating this video.
Wow, this video is the first one from your channel that I've seen, and it's already earned my subscription. Your enthusiasm, succinctness, and clear explanations are super impressive and I'm excited to go watch some more videos on your channel!
From Docker docs: "On Windows, the ability to toggle between Linux and Windows Server environments to build applications Fast and reliable performance with native Windows Hyper-V virtualization Ability to work natively on Linux through WSL 2 on Windows machines" Yes, you can run Linux environments on Windows machines.
"Fast and reliable performance with native Windows Hyper-V virtualization". Definitely not true, WSL2 might work better but running docker with Hyper-V is horrible and slow.
As a downside, as far as I understood, we should either disable Hyper-V and unable run "true VM" anymore(like VirtualPC), or enable it and then Docker@WSL2 will not run github.com/kubernetes/minikube/issues/4587 at least I failed to make them work altogether. As for performance - since I work with really light images(like NodeJS dev server), WSL2 looked pretty comfortable to me
You should follow up with docker-compose. I thought Docker was neat... then I discovered docker-compose and now Docker an absolute must. I have to have a strong reason to run ANY server software / services outside of docker-compose. My Octopi instance was a holdover but it's now in a container like most most my other home services. Need to move a service to another host? Move the compose config, move config folder, start it on the new host (and update HAProxy config - this is a step one for me and I love it).
@@jscul it costed me hundrets of hours allready... i was a linux guru before and everything worked just fine and it took me years to get there... now every kid can run a loadbalancer :D
I would assume that your next step would be javascript, then the next one should be a development framework, when you get to that one and the course or guide starts to tell how set up your environment, remember docker, there would be an image already setted up for you
@@alexisramis Where to go next depends on what he wants to do. If it's web design, yes. If it's building web apps - maybe not. I had a supervisor tell me - to learn SQL databases first. It's needed for pretty much all application development, and it's hard to do anything "real world" without it. Then learn a server side language (like PHP) - or learn them side by side. You could also learn JS as a server side technology with Node too, but idk if that route is really the best idea. It really all depends what you want to do.
well two things 1) i never felt so much attracted towards linux, although im thinking of learning it since many days, 2) no one could have given a better overview of docker than this. THANKYOU SIR
"I can't contain myself" where do you come up with this stuff, pure gold. Hit like on that note. I don't even know what you are talking about yet. I'm stepping up my geek and doing self taught things. Thanks for the insights.
Read latest trends in IT, find more in depth reading content and read some more, understand why it benefits an IT infrastructure/user, find a way to lab it, ask questions from others in the space, test/ tinker, and repeat. The more you learn across the IT nich spaces, the easier it is to learn and adapt to new technologies, because many newer technology solutions(not always) are existing protocols, languages, or frameworks applied in a new way. Edit: This is why Chuck is so good!
Chuck... You are like that teacher that you have in high school that everybody loved.. You have the whole gambit of qualities for teaching... You make learning fun and exciting! #beastmode..
You really have a great way explaining things...so much energy and passion! Great tutorials and video's...I'm really excited using docker on my RB Pi4! *thumbs up* from The Netherlands!
NC- I'm new to the whole IT world and like many others find your vids extremely helpful. I ran across this older vid and wanted to say 1) Kudos on the production quality of your channel over time. AND 2) I really found this video content style much more helpful. Not sure if all topics can be broken down like this one. However, taking the time to go into some of the background here on how the whole server virtualization process has evolved really gives a great 'forest' view of the overall concept. Thanks for all the time you put into your channel.
An absolutely fantastic trainer you are.. right from the thought 💭 to hardware to theory to practical hands on to any after thoughts 💭 you are covering it.. before this video I had to go through lots of documentation and articles to know about this.. one more thing you should mention though, that’s everyone keeps saying docker containers can be moved easily regardless of OS and HW, I don’t think that’s yet possible, Linux docker containers cannot be directly transferred to Windows, you would need a type 2 hyper visor and A linux VM on that windows first and vice versa. 👍👍
Man, I am very dyslexic so code has been a challenge, You finally showed me along with excellent pronunciation Caffeinated but clear. I understand now why I want to start with Docker and how to use it for my situation !! Thank You!
Holy "junk", dude, you're one of the few who DOESN'T get towed for parking on GTOger's channel! Seriously, that's pretty remarkable for the most famous parking lot on RUclips.
hi network chuck i started learning it since i watched your video on RUclips. before i don"t know any thing about it or computer science but now by self teaching i am playing by docker-playground creating docker image and docker container etc .thank you in deed i wish you and your family happy life and long live. most of your videos are downloaded and on my desktop because i have no internet accesses at my home i download using my mobile phone and watch on my old 32bit desktop but almost i am there .I did it because of a great teacher !!!!

Thank you for all you do. I'm attempting to learn linux and ideally become a white hat tester. My idea would be to set up a lab with multiple servers as targets and practice exploiting vulnerabilities. I'm totally new to this concept at 64 years old.
Watched your video, and the Kubernetes video, and deployed a 3 node cluster. You are so easy to follow and understand. Thanks for being concise and not overcomplicating.

I would like to see Docker's playlist of linux without using any CSP to get more bare bone idea of it. CSP makes lot of things easier and sometimes it confuses me what's happening under the hood.
It's easy to figure out yourself, build an ubuntu 'shitbox'. I found some old PC parts in my closet and slapped them together (Athlon ii x3 cpu, 8gb ram, 300w psu - OLD), installed linux, and i'm now configuring my own linux server one task at a time. Using chatGPT and other resources to help/guide me of course. I got my CCNA after months of study in Aug, drilling flashcards, watching videos, reading articles and whitepapers. I hated it. Learn by doing!
I'm finally getting into docker after 3 yrs. Thought it was complex but learning so using this vid to help with my learning. I'm using CLI not things like truenas or Synology.
@@widdermann100 so basically windows installs a hypervisor without explicitly saying so. Cheaterz ;D I figured it would be a bit complicated the way docker containers share certain "resources" between each other and the underlying os. Will need to research though, but my dev.game is not so strong atm. Cant really test it with steam and discord, or can i???
Ey man, watching from Germany. You should be a professor.. not joking at all! The way you explain and show these complex topics is amazing! I am just at the beginning of my IT journey but I always come back to your videos and get new drive for new topics! Love it!

en.wikipedia.org/wiki/VMware_ESXi so it's basically VMwares equivalent of ciscos IOS? OR is it simply another bare metal type 1 hypervisor, TYPICAL OS that happens to be popular because VMware uses it? - also what an abomination! PURPLE screen of death lol
Versions VMware ESX is available in two main types: ESX and ESXi, although since version 5 only ESXi is continued. ESX and ESXi before version 5.0 do not support Windows 8/Windows 2012. These Microsoft operating systems can only run on ESXi 5.x or later.[22] *VMware ESXi, a smaller-footprint version of ESX, does not include the ESX Service Console. It is available - without the need to purchase a vCenter license - as a free download from VMware, with some features disabled.[23][24][25]* ESXi apparently stands for "ESX integrated".[26] *VMware ESXi originated as a compact version of VMware ESX that allowed for a smaller 32 MB disk footprint on the host. With a simple configuration console for mostly network configuration and remote based VMware Infrastructure Client Interface, this allows for more resources to be dedicated to the guest environments.* Two variations of ESXi exist: VMware ESXi Installable VMware ESXi Embedded Edition The same media can be used to install either of these variations depending on the size of the target media.[27] One can upgrade ESXi to VMware Infrastructure 3[28] or to VMware vSphere 4.0 ESXi. Originally named VMware ESX Server ESXi edition, through several revisions the ESXi product finally became VMware ESXi 3. New editions then followed: ESXi 3.5, ESXi 4, ESXi 5 and (as of 2015) ESXi 6.

privacy.com can help you with that. Your real card information is never exposed to the company you need to use. They use ghost cards to make transactions, check it out!
Finally- after months of trying to understand docker, you sum it up perfectly. Yes, more videos, please.
BTW- How did you do the graphic overlay? Was it live or did you record it and add the overlay in post?
i too have the same question how he draw over the video footage.
What I assume he's doing is recording the screen that he's "drawing on". Then he takes that screen recording and places it over the video, probably key-ing out the background of the screen recording so that it is transparent.
My Best guess: He is drawing on Adobe Photoshop on a grey background + Screen records it. Later, he syncs the drawing with the video and removes the background easily (as it is all a single color). This probably means he can't use grey in his drawings, so if he ever does, I got sth wrong.
@@waleedawad4520 png maybe bcause it dosn't have a background or maybe macros
He has a studio tour video and in the first 10 mins he explains how he draws with a wiacom tablet onto a photoshop green screen which is keyed in onto his video. This can be done in live streaming as well
I wish I’d understand what’s in it for me 🤣. Not a Dev, not an IT guy, just a computer enthusiast, I found your channel while looking at pfsense tutos . Your delivery is top notch, I watched it all. Kudos.
18:40 you can install linux containers on windows because of the "Windows Subsystem for Linux" Microsoft built.
Yeah, that's really really recent. Even now, it is still experimental.
@@codeman99-dev WSL2 has done some pretty good progress.
@@fullstack_journey I am aware. I was just stating that the progress was extremely recent (because of the video's release date). As for the experimental part, I actually downloaded docker last week, and the WSL2 support is still called experimental in the settings. It is turned on by default though.

I was about to ask that. Thanks!
Docker is amazing, I’ve learnt allot from it over the past 8-9 months. Especially with volumes and docker networks. 😍 in love with docker 🐳
ESXi stands for Elastic Sky X Integrated. ESXi is a type-1 hypervisor, meaning it runs directly on system hardware without the need for an operating system
Great. Chuck has a very fun, energetic , interesting way of teaching the basics and upwards. Easy to follow and learn videos. 👌
Actually just covered Docker on the Devnet course, so more info and lab time with it is much appreciated!
heck yeah!
Thank you. I am from China. I got 500K job in LA by watching your videos. Buying a huge house in LA 6 months ago. Life has been great after escaping China.
Thank you again dawg.
This guy's a genius! He places the advertisement where I was already waiting for a download! Now to make that advert relevant XD
im the only developer that has learned docker in three shops. its great for sharing sql instances for debugging and its simple
But still, what the hell is Docker in simplified words.
Nor Priest in simple Word ” container ”
@@norpriest521 LiveOverflow has a video about some of the internal concept, absolutely worth watching. Clears all the mystification.
@@norpriest521 In a "explain like I'm 5" kind of way... it's like a VM in a way but it's not. You can run containers that will appear to be other physical machines on your network, you can run them on one machine and just have that machine handle everything. Whatever you want. It's hard to explain, which is why I stayed away from it for a long time... but then I started using it and holy shit, it's SO USEFUL.
Personally, I'll just stand up a VM and then use Docker to run whatever containers I want (just think of them as little VMs of sorts, even though they're not VMs by definition). Media server to stream shit to my TV/computer/FireStick/etc, DNS, SMB, Git repos, whatever. And if I ever wanna move a container to another machine, it's a matter of minutes (copy my Bash script, point it to the "volumes" as needed, run it, done).
Couldn't recommend it enough. It's one of the most ridiculously useful things to anybody in IT, it's FOSS, it's *stupid* easy to work with, etc. And to me, the best part is I can stay the fuuuuuck away from dependency hell. Docker will run on damn near anything so you just get it up and it'll handle all the rest. Not having to worry at ALL about unfucking dependencies left and right on a complicated system is absolutely amazing. 10/10 would recommend.
Eh not really
I have been to several Universities around the Middle East and Eastern Asia
I wish I had professors and teachers like you
You have the rithme
Thanx a lot
Sitting here looking at all my VMs I have in production after watching this video and thinking to myself what have I been doing with my life?!?
Great video, Chuck! One of my favorite CBT Nuggets trainers.
yep.. Probably spent a year or two just looking at my vm screens, praying it would finish just a little bit faster... :D
Depending on what type of applications you run, such as Java or Spring, putting things in Docker can be as easy as creating a Dockerfile and piping your output into a container. .Net is a different beast.
However, you CAN run straight Docker in a Prod environment if you want, but it's honestly best not to. I manage about 15 Kubernetes cluster for my company, all running .Net Core apps running in Docker containers. Little by little, we're taking apps off VMs and deploying then in K8s.
Wait until you get to k8s
What kinda vm are you guys using I never have vm problems lol
4:15 virtualization and virtual machines are virtualizing hardware.
Docker virtualizes the Operating System (OS). I think that is the point
And if you run docker on WIN10, it will activate "Hyper-V" function which mean if you like to use virtualbox or VMware(don't know about others) it will end up in error. Hyper-V doesn't like other hypervisors very much.
I have been told once that "You CAN'T RUN A CONTEINER AS A VIRTUAL MACHINE", what I always though was possible, because a container is "an OS with embedded applications".
Thanks to you video, today I know THEY ARE WRONG!
Thanks Chuck! Building my own home-lab with LOTS of improvements thanks to you channel!
Your excellent passion can be seen from your lucid teaching to resourcefulness! Thank you NetworkChuck!
Hi Chuck, i never post comments but you're video is too awesome not to comment upon. Love the fact that you got a real server, opened it up etc etc Seriously cool and excellently presented, thank you!
this is exactly what I have been searching for. I am a senior manager and not a developer and couldn't fully understand the other mechanical docker videos. thanks for creating this video.
Wow, this video is the first one from your channel that I've seen, and it's already earned my subscription. Your enthusiasm, succinctness, and clear explanations are super impressive and I'm excited to go watch some more videos on your channel!
From Docker docs:
"On Windows, the ability to toggle between Linux and Windows Server environments to build applications
Fast and reliable performance with native Windows Hyper-V virtualization
Ability to work natively on Linux through WSL 2 on Windows machines"
Yes, you can run Linux environments on Windows machines.
"Fast and reliable performance with native Windows Hyper-V virtualization".
Definitely not true, WSL2 might work better but running docker with Hyper-V is horrible and slow.
As a downside, as far as I understood, we should either disable Hyper-V and unable run "true VM" anymore(like VirtualPC), or enable it and then Docker@WSL2 will not run
github.com/kubernetes/minikube/issues/4587
at least I failed to make them work altogether. As for performance - since I work with really light images(like NodeJS dev server), WSL2 looked pretty comfortable to me
You should follow up with docker-compose. I thought Docker was neat... then I discovered docker-compose and now Docker an absolute must. I have to have a strong reason to run ANY server software / services outside of docker-compose. My Octopi instance was a holdover but it's now in a container like most most my other home services. Need to move a service to another host? Move the compose config, move config folder, start it on the new host (and update HAProxy config - this is a step one for me and I love it).
Me: 4 hours into learning HTML & CSS with hardly any IT education
RUclips: le recommend this
You can look at hub.docker.com/_/httpd/ if you want to serve your website with docker
@@jscul it costed me hundrets of hours allready... i was a linux guru before and everything worked just fine and it took me years to get there... now every kid can run a loadbalancer :D
I would assume that your next step would be javascript, then the next one should be a development framework, when you get to that one and the course or guide starts to tell how set up your environment, remember docker, there would be an image already setted up for you
@@alexisramis Where to go next depends on what he wants to do. If it's web design, yes. If it's building web apps - maybe not. I had a supervisor tell me - to learn SQL databases first. It's needed for pretty much all application development, and it's hard to do anything "real world" without it. Then learn a server side language (like PHP) - or learn them side by side. You could also learn JS as a server side technology with Node too, but idk if that route is really the best idea. It really all depends what you want to do.
@@cssguy2398 but you know the underlying tech
You’re a talented instructor. Really appreciate your skills and your delivery. Excellent work.
well two things 1) i never felt so much attracted towards linux, although im thinking of learning it since many days, 2) no one could have given a better overview of docker than this. THANKYOU SIR
Haha, thanks!
"I can't contain myself" where do you come up with this stuff, pure gold. Hit like on that note. I don't even know what you are talking about yet. I'm stepping up my geek and doing self taught things. Thanks for the insights.
Bro how do you continue to get better and better? I thought it was perfect but you always make things easier. Thank you
Read latest trends in IT, find more in depth reading content and read some more, understand why it benefits an IT infrastructure/user, find a way to lab it, ask questions from others in the space, test/ tinker, and repeat. The more you learn across the IT nich spaces, the easier it is to learn and adapt to new technologies, because many newer technology solutions(not always) are existing protocols, languages, or frameworks applied in a new way.
Edit: This is why Chuck is so good!
Chuck... You are like that teacher that you have in high school that everybody loved.. You have the whole gambit of qualities for teaching... You make learning fun and exciting! #beastmode..

You earned my "like" in under 20 seconds. The rest of the video was just icing on the cake
^ This is why we're doomed. Low expectations will facilitate the slow-death of us all.
NC- I'm new to the whole IT world and like many others find your vids extremely helpful. I ran across this older vid and wanted to say 1) Kudos on the production quality of your channel over time.
AND 2) I really found this video content style much more helpful. Not sure if all topics can be broken down like this one. However, taking the time to go into some of the background here on how the whole server virtualization process has evolved really gives a great 'forest' view of the overall concept. Thanks for all the time you put into your channel.
More videos on Docker. I would love to learn more about this.
An absolutely fantastic trainer you are.. right from the thought 💭 to hardware to theory to practical hands on to any after thoughts 💭 you are covering it.. before this video I had to go through lots of documentation and articles to know about this.. one more thing you should mention though, that’s everyone keeps saying docker containers can be moved easily regardless of OS and HW, I don’t think that’s yet possible, Linux docker containers cannot be directly transferred to Windows, you would need a type 2 hyper visor and A linux VM on that windows first and vice versa. 👍👍
I think WSL (Windows Subsystem for Linux) solves this issue. You can run linux containers on top of Windows OS.
Man, I am very dyslexic so code has been a challenge, You finally showed me along with excellent pronunciation Caffeinated but clear. I understand now why I want to start with Docker and how to use it for my situation !! Thank You!
Holy "junk", dude, you're one of the few who DOESN'T get towed for parking on GTOger's channel! Seriously, that's pretty remarkable for the most famous parking lot on RUclips.

Studying, because, going to try to use docker for redoing servers. My existing servers are using software from 2010.
I would like to see Docker's playlist of linux without using any CSP to get more bare bone idea of it. CSP makes lot of things easier and sometimes it confuses me what's happening under the hood.
It's easy to figure out yourself, build an ubuntu 'shitbox'. I found some old PC parts in my closet and slapped them together (Athlon ii x3 cpu, 8gb ram, 300w psu - OLD), installed linux, and i'm now configuring my own linux server one task at a time. Using chatGPT and other resources to help/guide me of course.

I'm finally getting into docker after 3 yrs. Thought it was complex but learning so using this vid to help with my learning. I'm using CLI not things like truenas or Synology.
Linux based containers can run on Windows Host. It's only the opposite that can't be done.
I concur. Chuck stated this incorrectly in this video.
@@widdermann100 so basically windows installs a hypervisor without explicitly saying so. Cheaterz ;D I figured it would be a bit complicated the way docker containers share certain "resources" between each other and the underlying os. Will need to research though, but my dev.game is not so strong atm. Cant really test it with steam and discord, or can i???
@@widdermann100 Microsoft threatened to include a real Linux kernel into future Windows versions. Maybe this behaviour will change then.

ESXi = Elastic Sky X Integrated (but why the lower case “I”?) also known a in previous versions as ESX
ESXi used to be the free/compact version of ESX.
en.wikipedia.org/wiki/VMware_ESXi
so it's basically VMwares equivalent of ciscos IOS? OR is it simply another bare metal type 1 hypervisor, TYPICAL OS that happens to be popular because VMware uses it?
- also what an abomination! PURPLE screen of death lol
Versions
VMware ESX is available in two main types: ESX and ESXi, although since version 5 only ESXi is continued.
ESX and ESXi before version 5.0 do not support Windows 8/Windows 2012. These Microsoft operating systems can only run on ESXi 5.x or later.[22]
*VMware ESXi, a smaller-footprint version of ESX, does not include the ESX Service Console. It is available - without the need to purchase a vCenter license - as a free download from VMware, with some features disabled.[23][24][25]*
ESXi apparently stands for "ESX integrated".[26]
*VMware ESXi originated as a compact version of VMware ESX that allowed for a smaller 32 MB disk footprint on the host. With a simple configuration console for mostly network configuration and remote based VMware Infrastructure Client Interface, this allows for more resources to be dedicated to the guest environments.*
Two variations of ESXi exist:
VMware ESXi Installable
VMware ESXi Embedded Edition
The same media can be used to install either of these variations depending on the size of the target media.[27] One can upgrade ESXi to VMware Infrastructure 3[28] or to VMware vSphere 4.0 ESXi.
Originally named VMware ESX Server ESXi edition, through several revisions the ESXi product finally became VMware ESXi 3. New editions then followed: ESXi 3.5, ESXi 4, ESXi 5 and (as of 2015) ESXi 6.
