debug-image

Build Docker image

Build for your current architecture:

docker build -t debug-image:local .

Build specifically for arm64 and load it into your local Docker image store:

docker buildx build --platform linux/arm64 -t debug-image:arm64 --load .

Build and push a multi-architecture image (amd64 + arm64):

docker buildx build \
  --platform linux/amd64,linux/arm64 \
  -t ghcr.io/<owner>/<repo>:latest \
  --push \
  .

Containers start as debugroot by default. This user has passwordless sudo.

Switch to the unprivileged debuguser account:

sudo -u debuguser -i

The workflow at .github/workflows/build-push.yml now builds and pushes both linux/amd64 and linux/arm64 images to GHCR.
