Docker Build and Push

Build and push multi-platform Docker images to Google Artifact Registry for any teammelosys repository.

How to Use

1. Detect repository name from current working directory (basename of git root or pwd)
2. Detect project type to determine build command
3. Build and push with the detected settings

Registry Pattern

europe-north1-docker.pkg.dev/nais-management-233d/teammelosys/{REPO_NAME}

Replace {REPO_NAME} with the actual repository name (e.g., melosys-api, melosys-web, melosys-eessi).

Detect Repository Name

# Get repo name from git remote or directory name
REPO_NAME=$(basename "$(git rev-parse --show-toplevel 2>/dev/null || pwd)")
echo "Repository: $REPO_NAME"

Detect Project Type and Build

Project Type	Detection	Build Command
Maven/Java/Kotlin	pom.xml exists	make build-fast or mvn package -DskipTests
Node.js/pnpm	pnpm-lock.yaml exists	pnpm install && pnpm build
Node.js/npm	package-lock.json exists	npm ci && npm run build
Makefile only	Makefile exists	make build

Build and Push Command

docker buildx build --platform linux/amd64,linux/arm64 \
  -t europe-north1-docker.pkg.dev/nais-management-233d/teammelosys/${REPO_NAME}:TAG \
  --push .

Replace TAG with user-specified tag.

Complete Workflow

1. Detect repo name: REPO_NAME=$(basename "$(git rev-parse --show-toplevel 2>/dev/null || pwd)")
2. Build the application based on project type (see table above)
3. Run buildx build with --push
4. Report: tag, platforms, manifest digest

Setup (if buildx not configured)

docker buildx create --name multiplatform --use --driver docker-container || docker buildx use multiplatform

Error Handling

Authentication expired

Message: "Reauthentication failed" Solution: Ask user to run gcloud auth login, then retry

No matching manifest for linux/amd64

Cause: Image built only for arm64 Solution: Use --platform linux/amd64,linux/arm64 flag

No Dockerfile found

Solution: Check if Dockerfile exists in repo root. Some repos may have it in a subdirectory.

Output Format

After successful push:

Done!
