+2 I like that proposal a lot! An ansible wrapper is then just an
example playbook in docs but could be done w/o ansible as well,
manually or using some other remote execution tooling of user's
choice.
Now that the phase 1 refactor is under review and passing CI, I think it's time to
come to a conclusion on this.
This option looks like the best compromise between keeping it simple and dropping the
least possible amount of features. So unless someone has a better idea, I'll work on
that as soon as the current review is merged.
Would it be possible :-
- By default we install everything, so all in one
- If our host is not CONFIG_CONTROLLER_HOST but is part of
CONFIG_NETWORK_HOSTS, we apply the network manifest
- Same as above if our host is part of CONFIG_COMPUTE_HOSTS
- If our host is not CONFIG_CONTROLLER_HOST but is part of
CONFIG_STORAGE_HOSTS, we apply the storage manifest
Just one more role. May we have 4 roles ?
Thanks
Boris.
