Vladimir Kozhukalov 978507351f Add ceph-adapter-rook chart
When using Rook for managing Ceph clusters we have
to provision a minimal set of assets (keys, endpoints, etc.)
to make Openstack-Helm charts work with these Ceph clusters.

Rook provides CRDs that can be used for managing Ceph assets
like pools/keyrings/buckets etc. but Openstack-Helm can not
utilize these CRDs. To support these CRDs in OSH would
require having lots of conditionals in OSH templates since
we still want OSH to work with OSH ceph-* charts.

Summary

This is the minimal set of templates necessary to make the rest of Openstack-Helm charts work with Ceph clusters managed by the Rook operator. Rook operator not only deploys Ceph clusters but also provides convenience when interfacing with those clusters via CRDs which can be used for managing pools/keys/users etc. However Openstack-Helm charts do not utilize Rook CRDs but instead manage Ceph assets like pools/keyrings/users/buckets etc. by means of running bootstrap scripts. Before using Openstack-Helm charts we have to provision a minimal set of assets like Ceph admin keys and endpoints and this chart provides exactly this minimal set of templates.

Usage

Deploy Ceph admin key and Ceph mon endpoint in the namespace where Ceph cluster is deployed.

tee > /tmp/ceph-adapter-rook-ceph.yaml <<EOF
manifests:
  configmap_bin: true
  configmap_templates: true
  configmap_etc: false
  job_storage_admin_keys: true
  job_namespace_client_key: false
  job_namespace_client_ceph_config: false
  service_mon_discovery: true
EOF

helm upgrade --install ceph-adapter-rook ./ceph-adapter-rook \
  --namespace=ceph \
  --values=/tmp/ceph-adapter-ceph.yaml

Now wait until all jobs are finished and deploy client key and client configuration in the namespace where Openstack charts are going to be deployed.

tee > /tmp/ceph-adapter-rook-openstack.yaml <<EOF manifests: configmap_bin: true configmap_templates: false configmap_etc: true job_storage_admin_keys: false job_namespace_client_key: true job_namespace_client_ceph_config: true service_mon_discovery: false EOF

helm upgrade --install ceph-adapter-rook ./ceph-adapter-rook
--namespace=openstack
--values=/tmp/ceph-adapter-rook-openstack.yaml


Again wait until all jobs are finished and then you can deploy other Openstack-Helm charts.
