DevContainer Test Repository

This repository tests the devcontainer.json → Dockerfile workflow for BinderHub.

How this works

1. The .devcontainer/devcontainer.json specifies the environment
2. We use repo2docker --write-dockerfile Dockerfile to generate a Dockerfile
3. Standard BinderHub sees the Dockerfile and builds from it

import os
print(f"TEST_VAR = {os.environ.get('TEST_VAR')}")
