Removing containers section starting at 31:38: If you're trying to remove all containers at once with the rm command in Windows cmd, and get "unknown flag -a" errors, you can try instead the "docker container prune" command which removes unused containers. Prune also works for unused "image", "network", or "volume", or docker system prune to do the lot at once. The docker rm $(docker ps -aq) might also work in powershell terminal or another shell if you have one installed but cmd would not let me use docker rm $(docker ps -aq).
The code at 44:20 is the following: docker ps --format="ID\t{{.ID}} NAME\t{{.Names}} IMAGE\t{{.Image}} PORTS\t{{.Ports}} COMMAND\t{{.Command}} CREATED\t{{.CreatedAt}} STATUS\t{{.Status}} "
1.45 hrs - The package.json file is downloaded into the folder by the 'npm init' command. 'npm install' command is used to unparse package.json and install the dependencies that are mentioned in the json file. The 'npm install express --save' command adds the package-lock.json file and Node folder and installs the dependencies specified in .json files.
Have been looking for a docker video for a long time, saw this upload this morning, and man this was productive. Great Explanation and concise examples. Now, I have to watch the kubes section.
Thanks for all the effort Great course .. and great learning experience coding with you guys! Nice detail in the docker part.. and I am completely new to k8s and found it really useful to know concepts on services, configmap and secrets. K8s content could be more wrt docker content. Also, pls update the video description with git resources. Thanks again.
Thank you!! Also if getting some error about lower case letters in windows. Put everything for -v in quotations for example: -v "/$(pwd):/usr/share/nginx/html:ro"
Great content and great teaching skills, thanks for sharing! Just an head up (minutes 23-24): stopping a container on windows, even without starting it with -d flag, did not stop the container daemon. I had to execute "docker stop [container id]" in order to really stop it.
If you got this 403 error, means that Nginx does not find the index.html file, point the volumen to the dist folder inside the Start Bootstrap - Grayscale directory
For anyone getting 403 error, you need to create the container in the dist directory of the Bootstrap project, not the website directory. Follow the same scripts in the dist directory and it should work
Docker course is really good, I was able to understand every concept and have a hands-on experience. But K8s part is not that much good though there is scope for improvement, at some places the instructor got confused and was unclear at some places.
Also docker images do not have a version. They only have a tag which is a string. So if you pull the alpine version you actually are hoping you are pulling the latest, but it could be any version.
You two are modern gods. Thank you so much for this. Thank you freecodecamp too for sharing, I can always trust anything I watch from their channel will be amazing content. Subscribed to both channels :) Keep it up
Thanks for this video. It helps a lot. Now, how do we deploy our app to a production server on a public domain/IP? Do we need to use another tool such as Jenkins, etc? I have a little flask app running locally using docker compose. How do I go about making changes locally and deploying those changes to my web host server so the world can see it and use it? Thank you for your great tutorial again.

@Nana Earlier in your presentation you used Deployment for stateless applications and StatefulSet for stateful (like DB).. What is the reason you used a deployment for MongoDB ? I'd expect Statefulset
If you run into "The connection to the server localhost:8080 was refused - did you specify the right host or port?" Be sure to execute "minikube start" :D

Docker rm should remove the container Rm command usually used to delete So if we deleted the container don't we need to install the docker image then run the container? Means rm just removes the image from the cli but the image will be in background consuming disk space? I'm i correct?

The solution for me for this was to install WSL version 2.
yeah i am facing the same things
for /f "tokens=*" %i in ('docker ps -a -q') do docker rm -f %i
Use this command instead it works

What a guy 🍻
thanks bro...
was looking for all over the place ! thanks! lol
thanks man
finally finished after three useful weekends.
Thanks for the video. :) By the way: I think "LTS" doesn't stand for "latest", but for "long term support".
You are correct
Yep. True.
LOL did they say LTS as latest? Hahahaha

I think 7:10 is not correct. VM with type two hypervisor shares host OS (typically some kernel). I agree if you explain only type one hypervisor.

I'm i correct?
So Docker is basically the advanced hi-tech ship and K8s is the smart manager dealing with logistics and what not.
can we also change the port number ?
