Options

• -v: Show the current version
• -app: Application name
• -output: Output directory (default .)
• -yml: Compose file path (default docker-compose.yml)
• -docker-host: Docker host connection
• -interactive-bash: Include option to run the generated script with interactive bash. Running the generated script without any argument will executed it normally. But running it with --interactive-bash will execute the container with interactive bash. Pretty handful for debug.

Build

Using goxc.
