With all references to the nfs-ganesha RGW FSAL removed from this
branch, the remaining ceph_nfs_rgw_* are no longer used
anywhere. Remove them in order to avoid potential user confusion.
As Ali Maredia explains (in
https://github.com/ceph/ceph-ansible/issues/1907#issuecomment-331200448),
since the Ceph RGW/NFS gateway (with the nfs-ganesha RGW FSAL) is not
supported for any stable Ceph release prior to Luminous, the
nfs_obj_gw variable does not serve any real purpose in this
branch. Thus, remove it along with all references that use it.
Add the ceph_nfs_ceph_user variable to nfss.yml.sample too (not just
all.yml.sample).
This was properly included in ada2f147f5
in master, but was missing from
72e32ae0bf in stable-2.2.
We changed the way we declare image.
Prior to this patch we must have a "user/image:tag"
format, which is incompatible with non docker-hub registry where you
usually don't have a "user". On the docker hub a "user" is also
identified as a namespace, so for Ceph the user was "ceph".
Variables have been simplified with only:
* ceph_docker_image
* ceph_docker_image_tag
1. For docker hub images: ceph_docker_name: "ceph/daemon" will give
you the 'daemon' image of the 'ceph' user.
2. For non docker hub images: ceph_docker_name: "daemon" will simply
give you the "daemon" image.
Infrastructure playbooks have been modified as well.
The file group_vars/all.docker.yml.sample has been removed as well.
It is hard to maintain since we have to generate it manually. If
you want to configure specific variables for a specific daemon simply
edit group_vars/$DAEMON.yml

Prior to this patch we had several ways to runs containers, we could use
ansible's docker module on some distro and on containers distros we were
using systemd. We strongly believe threating containers as services with
systemd is the right approach so this patch generalizes to all the
distros. These days most of the distros are running systemd so it's fair
assumption.
