dockerimage

github.com/papercomputeco/daggerverse/dockerimage

Builds a Dockerfile locally or publishes a multi-platform OCI image.

Publishing defaults to linux/amd64 and linux/arm64. Registry authentication is supplied by the caller's Dagger environment.

Run the image fixtures for both platforms with make test.

Usage

Build locally

dagger call \
  -m github.com/papercomputeco/daggerverse/dockerimage \
  --source=. \
  build \
  export-image --name=my-app:dev

Build a specific platform with a build argument, without loading it:

dagger call \
  -m github.com/papercomputeco/daggerverse/dockerimage \
  --source=. \
  with-build-arg --name=LDFLAGS --value="-s -w" \
  build --platform=linux/arm64 \
  sync

Repeat with-build-arg to pass more than one argument.

Publish

dagger call \
  -m github.com/papercomputeco/daggerverse/dockerimage \
  --source=. \
  publish \
    --repository=registry.example.com/team/my-app \
    --tags=v1.0.0 \
    --tags=latest

Use constructor options to select another Dockerfile or replace the default publishing platforms.

For release workflows, pin the module to a commit instead of floating on the default branch.
