How to Run and Debug Python Inside Docker Containers Using VSCode
You don't need to have Python installed on your system in order to run it. Replace Python with almost any other language and keep your computer free from all the things you need to have installed in order to start developing software!
Version collisions are in the past. Create a docker image for each of your projects that you're working on and you will not have to spend hours or days fixing a local environment because you upgraded a package that broke everything.
In this video, I will show you a couple of ways to run Python in a Docker container, and in the end, we will set up VSCode (Visual Studio Code), so you could run and debug your code inside a container without leaving VSCode!

Awesome Video. Im busy with a project to use Python Data Science tools inside docker, but the tools then control metatrader inside wine. So I can have many algorithms running at once. I like the fact that I can debug line by line the Python code as it controls metatrader

Thanks. I couldn't find the 'Remote - Containers' extension in VS Code but I found something called 'Dev Containers' by Microsoft which sounds like the same thing. Has the name changed maybe?

Correction. Dev Containers will probably work on its own but it's included in the Remote Development extension, which is a pack that not only lets you connect to Docker containers from VSCode but also ssh into other hosts

Hey! Awesome video! Just a quick question, when I reach the part after I click "Reopen in Container" ... I'm not getting the option to open "From Dockerfile" (7:22 in your video) , I get a list of configuration template. Do you know why maybe?

Nice explanation. Thanks . Do you some some video to map network drive in docker container?
@codevev
2 ай бұрын
Thanks! I don't have a video about mapping network drive to a container yet. I haven't used Docker much lately. Good luck!
This is nice, thank you, I just wonder if it could somehow work with K8s, so when your container dies, VS Code still works (as container would just simply restart) ... Also would be great to see version control integrated into this.

Thanks! Could you clarify if the VSCode actually created the container itself or connected to an existing container? @7:16. It looks like VSCode created a container to me, because it didn't ask for container name or id.

It should have created a new container on its own

How do we handle venv and requirements.txt. It would be great if you can cover that
@codevev
2 жыл бұрын
That's really the beauty of running Python inside the Docker container! You actually don't need venv because a container is an isolated environment. Hence, no special treatment of requirements.txt is needed but of course it depends on what exactly you're doing
Hej Thx Evgeny! But could you explain the next steps on e.g. launch.json and how to configure properly? I have my problems there ... Cheers

You may have a typo in your Dockerfile. Sounds like it's not finding the path to the main.py file.

@@damircicic I had same problem. I can open container with rootless in VS code. You can google "Run the Docker daemon as a non-root user (Rootless mode)" to fix permission problem.
I appreciate your explanations. Very clear and the step by step procedure is very nice. However I don't manage to do the last part. I get and error reopening the project in the container : [7105 ms] Start: Check Docker is running [7105 ms] Start: Run in Host: docker version --format {{.Server.APIVersion}} [7177 ms] Server API version: 1.41 [7178 ms] Start: Run in Host: docker volume ls -q [7225 ms] Host server: Error: spawn docker ENOENT at ChildProcess._handle.onexit (node:internal/child_process:283:19) at onErrorNT (node:internal/child_process:476:16) at process.processTicksAndRejections (node:internal/process/task_queues:82:21) [7270 ms] Host server: (node:11049) PromiseRejectionHandledWarning: Promise rejection was handled asynchronously (rejection id: 1) (Use `node --trace-warnings ...` to show where the warning was created) [7274 ms] Error: spawn docker ENOENT at ChildProcess._handle.onexit (node:internal/child_process:283:19) at onErrorNT (node:internal/child_process:476:16) at process.processTicksAndRejections (node:internal/process/task_queues:82:21) The only difference with you is that I did the first part already in a remote access, in SSH. However "reopen in container" is supposed to work. Any idea, welcome. :-)

I think when you reopen in container, it just looks for Docker running on your local host. So if you hadn't installed it there, it can't find the running instance of Docker and is throwing an error. I'm actually not sure if what you're trying to do is supported, might be a good thing for me to try figuring out. But at my new job we aren't currently using docker containers and I do all of my development on an ec2 instance via remote ssh through VSCode😂
Unfortunatly there is no Remote - Containers extension on my VS code :(
