#Docker #DevOps
Docker is the de facto standard for building, shipping and running applications in a consistent manner. That's why most companies use it and are looking for developers with Docker skills. If you're looking for a career in software or DevOps engineering, you must have Docker on your resume. And not only that, you should know it well and be able to use it to effectively package and deploy your applications.

Just starting my coding journey and found your website and courses by accident. Couldn't be more thankful for what you have put together. You're such a gifted teacher! Learning SO much thanks to you!! :)
did you get the zip file?
@@edwinchiboko3737 yah dude where is the zip file
Finally the legend is back 😎
Thank you! Please support me by liking and sharing this video. :)
Learning is a continuous process
Absolutely mosh!..
Done :-)
@@programmingwithmosh Hello Sir! How can I Unsubscribe Code with Mosh? I've Completed My courses. Thanks a Lot!
I only appreciate your lectures after going through the ones done by others. This guy is a genius teacher.
did you get the zip file
at 5:50 you mentioned the zip, there is not zip file link in the video description.
You're the frickin' BEST teacher here, Mosh! Man, if I become a IT teacher one day, I hope I can be like you! You explain everything so clearly, you seem to understand what people need to get something. That comparision you did beetween json and yaml what GOD TIER.
I bought you Redux course and IT WORTH EVERY CENT!
How can you find the code?
did you get the zip file
thank you!! where is the zip file you mantion in 5:54?
my king mosh i love you so so much, you taught me how to be the best programmer big love from africa Ethiopia.

Regarding JSON vs YAML: It's not only about performance, but also about validation and security.
If you, e.g. copy+move some lines from a JSON file to another location, most likely, the JSON will be corrupt and incorrect, and if not, it's very likely, the order didn't matter anywhere. That's good behaviour for anything that mainly computers operate, as such a copy+paste error easily happens while editing (or merging with git), but might not be reviewed by (many) humans, so might be undetected for a long time. In YAML, there is a good chance, randomly moving blocks around, the end result is a different, but still correct YAML. Indeed, that's such a common error, that for bigger projects you usually have to write an own linter for the yaml files checking e.g. if the keys are the expected ones. Regarding security: YAML specification is a bit bigger than XML, so it contains a lot of hard to implement and possible insecure options. That's why many first naive implementation of YAML parsers in programming languages were replaced over time by other parser only implementing a secure subset of YAML. (Or alternatively that's tackled by the custom linters you have to write anyway)
There are some other subtle problems with YAML, e.g. your question of why you have to put "3.8" in quotes is because otherwise it would be detected as float und depending of whether can be represented in binary internally exactly or only close to it (indeed, 3.8f == 3.7999999523162841796875). The easiest way to enforce consistency is to demand that the version is always a string and not sometimes a string (3.8.0 == "3.8.0"), sometimes a float (3.8 == 3.7999999523162841796875) and sometimes an int (4 == 4).
There are many more subtle possibilities to misinterpret the unquoted strings: Magic words like true or false are becoming booleans. A minus sign is very often interpreted as list start, several further characters like +, |, also have special meanings and so on. When in doubt, always put your strings into quotes, from a practical standpoint that the system should what we want to say in the yaml, even though readability is reduced.
That's why, where high predictability is wanted, often enough different formats are used with less surprisings. E.g. HCL for Terraform, Programming languages for Pulumi, AWS CDK, ... or just toml/ini files.
Anyway, the high readability, easy understanding and universal structure of YAML dominates pretty much every modern stack, so the solution to all the above problems are custom linters and performant YAML parsers (most often with an own subset or dialect).
BTW, JSONs have disappointing also ambiguities that can even be exploited, e.g. the spec does not tell anything what should happen if a key is duplicated (which value to take). Different parsers handle that differently, and for the right combination, you can pass the validation done by the first parser to then inject some malicious (or just unintended, unwanted) behaviour to the second parser.
Thanks for the info man
I couldn't be more thankful for what you do!
so proud of You Mosh ! I'm from Iran , Hamedan too. !!
You are AMAMAMAMAZING Mosh.. God Bless you for the free stuff!
Thank you for this tutorial, I was having problems until I saw your video thank you very much
If you are wondering why the version number is string, it's because version can be something like 3.8.1 which is not a number.
Being a metalhead for decades. I just found my new favorite person and that guy's name is Mosh! \M/
This video cleared my doubts, love the content.
thank you Mosh for your high quality and amazing tutorials. wish you the best.
Hello Mosh! Thank you for making these amazing tutorials. Could you please link the zip file that you are referring to in this video so that we can follow along? Thank you!
You are the best teacher ever you explain once and I allredy understand.😄😄
You're a life saver Mosh, this is just what I was looking for💯
did you get the zip file
Superb Mosh-jan. Thank you. I say this without prejudice. Content is fluid, it stops to point out significant landmarks without cluttering, and therefore the duration is also tolerable in this age of millisecond attention spans. I learned a lot and refreshed a lot.
did you get the zip file
Thank you Mosh, you always make good tutorial!
Thank You Mosh! I'm gonna take your course!
Thanks for this wonderful tutorial.
I'm trying to follow however could not find the link to download the zip file.
I really enjoy ur videos with great understanding, I want to be a software developer but I don't know which programming language to learn first, and where to start 😶
I hope you will continue and thank you very much
you are my teacher
Thank You Mosh. This tutorial was great!
thank you so much for shaing your knowledge in an intersting way
good stuff. thank you. now the world needs your take on svelte!
It would be great if you could make a course on Devops tools ( Open source tools ) with the CI /CD Pipeline.
Amazing tutorial! i'm so tired of just stackOverflow codes without explain, thanks so much!
I think you would get better feedbacks (likes) If you had attached the zip file you mentioned.
I like your tuts very much dude. Simple but practical
thanks Mosh. as always, great tutorial.
This was one hell of a great video. You have a great teaching style. You are VERY clear in your explanations. And best of all, your screen captures are MOBILE-FRIENDLY. This video was missing the 1 thing I came looking for, but I am glad I watched the whole thing. Liked. Subscribed. Will look over your courses and purchase any that are remotely relevant to my needs. ☮❤🌈
PS: What I needed was how to do a "reverse port map/access". That is, I need initiate "from contain to host", instead of the "from host to container" that is explained EVERYWHERE. I have since learned this is done via `docker run --add-host=host.docker.internal:host-gateway` or in docker-compose.yaml `extra_hosts: ["host.docker.internal:host-gateway"]` Then [for example] your container can access the CUPS printer on your host machine via port: 631 on host: host.docker.internal
Mosh we are so glad to see you're back
Your are the best "mosh".. no one can beat you
Thank you! Please support me by liking and sharing this video. :)
Where is the Zip file? As stated in this video at 5:47...
The reason version has to be in quotes for docker-compose is that yaml spec parses numbers such as 3.0 to 3 and it breaks versioning.
Great explained. Thank you so much.
what a great content! so grateful to you
I learned so much from your 6 hours python course .Thank you so much Mosh🙏
Thank you for this wonderful tutorial

where is the zip file ?
Congrats ! The course is awsome ! Thank you :)
im from iran and thanks for your very nice course
Really appreciate your content Mosh!
Great tutorial , that helped me well
Thanks
Thank you for the explanation
Thanks for your excellent video!! Where I can download the files did you use in your examples?
Very Very Thank Your videos are very good.
Flutter tutorial please, we have all been waiting so long for that 😀👍
Fantastic course
You are always awesome. Everybody loves you :)
Amazing tutorial
I just want to let you know that your courses are top class.
One improvement I would like to see in your course is the project you develop during the lectures. Even though *Vidly* is really a good project, I would like to see much complex project than that. Maybe an e-commerce project. Point is: you have tons of cool techniques to improve the quality of code which we can learn from your experience.
Where can I find the Vidly zip file ?
Happy to see you brother!! Love from India 😍
The tutorial is amazing, but where is the zip file itself with the demo project?
You're a Pro, Mosh! Thanks vm
just wondering where the zip file is located??
yeah... same here!
Hey Mosh, please make a course on Android studio and WordPress.
This was really helpful. Thank you.
very helpful
I love your tutorials
Really really it's great to see u on live ❤️❤️

Thanks for that, was looking for this. @programmingwithmosh you should add this to your description.
@@KlausbergerYT too basic, see above.
You're the best mosh ❤️💙
You're an excellent tutor.
Thanks for sharing, it was a useful video.
Need more videos on docker Thanks!
Thanks for this tutorial!!!
at 5:50 you say that below the video is a zip file, but there is no zip file.
I looked for the zip file as well but couldn't find
Great video, Thank you!
hi moshi, long time , you the best man
Really great videos , well explained , just awesome !
14:10 version must be a string because it's not a float number. Versions are multidot structures like 3.8.1

thank you mosh ...lovely !!
Love it, I’m being stuck for 2 weeks
woww!! Thank you so much Mosh for such great content, I'm a 1st yr CSE college student in India and request you to please make a OOPs in c++/ python !!, I saw ur 7min video on OOPs and I really understood it very well
Please can you code for crypto arbitrage for different exchanges?
How is the experience at a programming college? I also want to go the path of coding (I'm indian).
Finally Mosh ❤️❤️❤️
This guy is thug, everything is easy in his world. Thanks so much for all the effort Moch!
Thanks, very useful. Well done.

Where can I find the zip file for backend and frontend projects mentioned in the video?
Same question here =(
I don't know either so replying here so hopefully I get a notification if someone tells you.
Purchase the course
Nice tutorial, thanks. It's full of valuable information.
👆send a direct message for support and guidance
nicely explained
Hey Mosh
Where is the source code? He said he was going to attach the zip file, but failed to find it here. Can someone please pin that out for me?
This is a part of his course on Udemy. So it is for those who paid on Udemy!
5:48 - You said, you attached the zip file. It's not here.
Thanks for the tutorial though.
Helpful , thanks
I was waiting for this ep. and enjoyed it!!!!! :DDDDD
But can you please make a c++ beginner tutorial?
Thank you so much for this precious tutorial. You talked about a zip file. Please, where can we get it so that we can follow up what you are teaching us?
THANK you again!
Do you get the answer yet?i still couldn’t find it as well
Are you sharing the code for this tutorial anywhere?
Thanks for sharing
You are awesome 🔥🔥
Hey Mosh, thanks for this tutorial, very handy. BTW can you attach a zip file you mentioned, I would like to get my hands "dirty"
yes Please, have you found the zip file already?
@@kazimali901 Nope dude
where is the ZIP file to follow the examples?
Hey Mosh, I don't know if I somehow missed the information, but where is the zip file you mentioned ?
Can't find it anywhere
Great job 👍.
