Philosophy

Kaigara is a standard way for a container ENTRYPOINT. It can setup or upgrade your application configuration before starting the process.

Kaigara operate with 3 main components Metadata, Operations and Resources.

Metdata: In development you can set default variables into your metadata.yml file In production or other stages you can either use shell environment or better etcd/consul.

Resources: A directory copied on the target system containing templates or files to by manipulated from Operations. The templates will be rendered using application metadata.

Operations: A directory of scripts copied into the target system, they will be executed one by one in alphabetical orders, we would usually use first operation for setting up application volumes for persistant and application specific configurations. The sub-sequents operations are configuration changes and upgrades, similar to database migrations.
