Usage: scripts/docker-publish.sh [OPTIONS]
Builds and/or pushes the ActivityWatch MCP Docker image to GitHub Container Registry.
Tags are derived from the current package.json version (`v<version>` and `dev`).
Additional docker build flags may be appended after "--".
Options:
-t, --tag TAG Additional tag to publish (can be repeated)
-f, --file PATH Path to Dockerfile (default: docker/Dockerfile)
--context PATH Build context directory (default: repository root)
--build-only Build the image but skip push
--push-only Push the image without rebuilding
--dry-run Alias for --build-only
-h, --help Show this help message
Environment variables:
REGISTRY Registry hostname (default: ghcr.io)
IMAGE_REPOSITORY Repository in owner/name format. Auto-detected when possible.
PUSH Set to 0 to skip push (same as --build-only)
BUILD Set to 0 to skip build (same as --push-only)
DOCKER_BUILD_ARGS Extra args appended to docker build (space-delimited)
