aah generate script --name docker

# OR shorthand
aah g s -n docker

Using Dockerfile.{dev, prod}

Various sample usage commands.

# Using Dockerfile.dev
docker build --no-cache -t "your-app-image-name:dev" -f Dockerfile.dev .

# Using Dockerfile.prod
docker build --no-cache -t "your-app-image-name:latest" -f Dockerfile.prod .
