Development tools in containers

Multiarch development environments

Setup

  1. Enable the beta GitHub Container Registry service on your GitHub acct
  2. Fork this repo under your GitHub user
  3. Clone the repo locally
  4. Edit docker-compose.yaml to include registry paths from your GitHub user
  5. Run an environment
    • For the dev shell docker compose run dev /bin/bash -l
    • For JupyterLab:
      1. Generate ssh keypair: ssh-keygen -t ed5519 -f ~/.ssh/scidev
      2. Copy the public component to the container persistent storage:
        1. docker compose run dev /bin/bash -l
        2. paste scidev.pub into ~/.ssh/authorized_keys
        3. chmod 0600 ~/.ssh/authorized_keys
      3. On your local machine create an .ssh/config entry:
        Host scidev
          HostName localhost
          Port 2222
          LocalForward 8888 sci:8888
          User 'your GitHub user'
          IdentityFile ~/.ssh/scidev
        
      4. docker compose up
      5. ssh scidev
      6. Open http://localhost:8888 in a browser
  6. Install an R kernel: install.packages('IRkernel'); IRkernel::installspec()
  7. This allows for multiple GPG keys per container volume. The git config, ~/.config/git/config is common between the host and container, but ~/.config/git.signingkey can reference different subkeys.
    • Add the following include statement in the global git config:
[include]
path = ~/.config/git.signingkey
