Advice on setting up a hybrid Java and Python devcontainer

I want to setup a devcontainers environment for a Django Python project. I was curious about using the SonarLint extension.

SonarLint has a dependency on the JRE11+ being installed.

What is the best approach to take in setting up a devcontainer for this type of project?

What am I trying?

At the minute I am unsuccessfully trying to look at the following folders to try and set my own Dockerfile and devcontainer.json up.

https://github.com/devcontainers/images/tree/main/src/java https://github.com/devcontainers/images/tree/main/src/python

This uses the mcr.microsoft.com/devcontainers/base:bullseye. My thoughts were to copy the Dockerfile instructions as per the Java Dockerfile then trying to install Python 3.11 separately.

RUN arch="$(dpkg --print-architecture)" \
  ...

 RUN apt-get update && export DEBIAN_FRONTEND=noninteractive \
     && apt-get -y install --no-install-recommends python3.11 python3-pip

Which yields the following problems in the log file:

#0 5.837 E: Couldn't find any package by glob 'python3.11'
#0 5.837 E: Couldn't find any package by regex 'python3.11'

I’ve attached by feeble attempt at this for the devcontainer.json and docker file.

Wow… So it does work 😃 Thanks a lot

{
	"image": "mcr.microsoft.com/devcontainers/python:3.11",
	"features": {
		"ghcr.io/devcontainers/features/java:1": {
			"version": "11"
		}
	}
}

Hi @andez2000 👋

Could you try with this Dev Container config 👇 ?

// .devcontainer/devcontainer.json
{
	"image": "mcr.microsoft.com/devcontainers/python:3.11",
	"features": {
		"ghcr.io/devcontainers/features/java:1": {
			"version": "11"
		}
	}
}
