Atomicapp Lifecycle Definition

fetch

Will download and combine artifacts from the target application and any dependent applications including sample answers.conf file into a local directory for inspection and/or modification. Same for all providers.

install

Peform actions to prepare application to run. Performs validation of Nulecule as well as some provider specific implementation:

Provider	Implementation
Docker	Run the command embedded in the INSTALL label in the container image.
Kubernetes	Deploy artifacts to Kubernetes with replica count = 0
Openshift	Deploy artifacts to Openshift with replica count = 0 OR Upload template if artifact is a template.

run

Run an application. Provider specific implementation:

Provider	Implementation
Docker	Run requested containers on local machine.
Kubernetes	Increase replica count from 0 to >0.
Openshift	Increase replica count from 0 to >0 OR Instantiate template.

stop - (opposite of run)

Stop an application. Provider specific implementation:

Provider	Implementation
Docker	Stop requested containers on local machine.
Kubernetes	Decrease replica counts to 0.
Openshift	Decrease replica counts to 0.

uninstall - (opposite of install)

Remove deployment configuration from platform. Provider specific implementation:

Provider	Implementation
Docker	Run the command embedded in the UNINSTALL label in the container image.
Kubernetes	Remove artifacts from Kubernetes.
Openshift	Remove artifacts from Openshift. Delete template from openshift.

clean - (opposite of fetch)

Remove artifacts files from local system and clean up directory. Same for all providers.

I think "remove" would be a better verb instead of "clean". Clean is confusing for me.

Perhaps "clean" should be "localclean" as it is a local command. I would add "fullclean" (or something less horrible) that will also remove download images from local registries/caches.
