Use the image

ghcr.io/wyrd-company/devcontainers/base

Name the image in devcontainer.json. Set "overrideCommand": false so that the image command stays active and s6-overlay keeps running as PID 1.

{
  "image": "ghcr.io/wyrd-company/devcontainers/base:noble",
  "overrideCommand": false
}

Use resolute or ubuntu26.04 for Ubuntu 26.04 LTS.

Features

The service Features in wyrd-company/devcontainers require this image, or another image that uses s6-overlay 3 with /init as its entrypoint. Add them in features:

{
  "image": "ghcr.io/wyrd-company/devcontainers/base:noble",
  "overrideCommand": false,
  "features": {
    "ghcr.io/wyrd-company/devcontainers/caddy:1": {}
  }
}

Do not add the common-utils Feature on top of this image; it may reinstate unrestricted sudo for the user it manages. See sudo.
