  -n | --namespace NAMESPACE | --network NETWORK :
                    Namespace for Kubernetes alternatively network for Docker.
                    For K8S -> Overrides configured namespace name
                    For Docker -> Overrides configured network name. Note!

  generate-local-hosts-file-minikube :
               Generate hosts file delta for services deployed in local
               Kubernetes cluster (minikube). Content needs to be added to local
               ../etc/hosts file
  info       : List bundle information
  list       : List all deployed services for a given bundle
               For Docker: addresses and host ports and user/psw
               For K8S: Ingresses to services and user/psw
  list-bundles :
               List available bundles
  list-packages :
               List available packages for choosen bundle. Use flag -p <package>
               to list services in package. Packages are pre-defined service
               combinations from the bundle.
  list-psw   : List all user & psw for deployed services for a given bundle
  remove     : Remove a given bundle services.
               For Docker: All services for bundle will be removed.
               For K8S: All services removed (or specific service(s) and/or
               package if given). Namespace NOT removed.
  restart    : Restarts all running bundle services (or specific service(s)
               and/or package if given). For Docker: dependent services will NOT
               be restarted.
               For K8S: the services will be deleted and installed again.
  start      : Starts all services in a given bundle (or specific service(s)
               and/or package if given)
  status     : Checks the status of a deployment
  stop       : Stop all running services in a given bundle (or specific
               service(s) and/or package if given). For Docker: dependent
               services will NOT be stopped. This command is NOT applicable for
               K8S.

Available bundles:
$(get_bundles)

Examples:

Use configurations in config-default.bash

Start the complete Eiffel bundle
$ ./easy2use start Eiffel

Start three specific services from the Eiffel bundle
$ ./easy2use start Eiffel --services rabbitmq,mongodb,er

Start a predefined package of services from the Eiffel bundle
$ ./easy2use start Eiffel --package min

Examples :
Override configurations in config-default.bash file via flags

Start the complete Cx bundle in Kubernetes and in namespace = cx, and with base domain name = test.com
$ ./easy2use start Cx -t Kubernetes -n cx -d test.com

Remove the complete Cx bundle in Kubernetes
$ ./easy2use remove Cx -t Kubernetes -n cx
