Usage

jake build                      # Build Docker image
jake build tag=v1.2.3           # Build with specific tag
jake up                         # Start docker-compose services
jake logs                       # Follow logs
jake push                       # Push to registry
jake deploy                     # Deploy to production
jake clean-all                  # Full Docker cleanup

Key Features

Tagged Builds

Override the tag with parameters:

jake build tag=v1.2.3
jake push tag=v1.2.3

Multi-Platform Builds

Build for multiple architectures with buildx:

task build-multi-platform:
    docker buildx build \
        --platform linux/amd64,linux/arm64 \
        -t {{registry}}/{{app_name}}:{{tag}} \
        --push \
        .

Development Workflow

Quick commands for local development:

jake up       # Start services
jake logs     # View logs
jake shell    # Enter container
jake restart  # Restart everything
jake down     # Stop services

Safe Destructive Operations

Confirmations for dangerous commands:

task db-reset:
    @confirm "This will DELETE all data. Continue?"
    # ... reset database

Customization

Update configuration variables:

app_name = "myapp";
registry = "${DOCKER_REGISTRY}";
tag = "latest";

docker-compose.yml Example
