Working kubernetes cluster with multiple computes where node labeling is done according to theirs roles.

For openstack we will require the following labels:

  • openstack-control-plane=enabled - for k8s computes that will host openstack control plane containers
  • openstack-compute-node=enabled - for k8s computes that will host openstack compute nodes
  • openvswitch=enabled - for k8s computes that will host openstack network gateway services and compute nodes

For ceph we will require the following labels:

  • role=ceph-osd-node - for k8s computes that will host ceph osd's

Example of node labeling:

$ kubectl get nodes --show-labels

Deploy helmbundle controller

The controller manages releases of helm charts:

$ kubectl apply -f crds/helmbundle/helmcontroller.yaml

Deploy Ceph

Deploy rook controller

$ kubectl apply -f crds/helmbundle/ceph/rook.yaml

Deploy ceph cluster

$ kubectl apply -f crds/ceph/cluster.yaml
$ kubectl apply -f crds/ceph/storageclass.yaml

Share ceph metadata with openstack

Import secret from ceph-rook namespace:

$ kubectl get secret rook-ceph-admin-keyring -n rook-ceph --export -o yaml | sed -e 's/keyring:/key:/' | kubectl apply -n default -f-

Import ceph.conf configmap as well:

$ kubectl cp rook-ceph/$(kubectl -n rook-ceph get pod -l "app=rook-ceph-operator" -o jsonpath='{.items[0].metadata.name}'):/etc/ceph/ceph.conf /tmp/ceph.conf && sed -i 's/[a-z]1\+://g' /tmp/ceph.conf; sed -i '/^\[client.admin\]/d' /tmp/ceph.conf; sed -i '/^keyring =/d' /tmp/ceph.conf; sed -i '/^$/d' /tmp/ceph.conf;

$ kubectl create configmap rook-ceph-config -n default --from-file=/tmp/ceph.conf

Deploy infra components

$ kubectl apply -f crds/helmbundle/openstack/ceph/infra.yaml

Deploy storage independeng openstack services

$ kubectl apply -f crds/helmbundle/openstack/common/openstack.yaml

Deploy rest of core openstack

$ kubectl apply -f crds/helmbundle/openstack/ceph/glance.yaml
$ kubectl apply -f crds/helmbundle/openstack/ceph/cinder.yaml
$ kubectl apply -f  crds/helmbundle/openstack/common/openstack-network.yaml
$ kubectl apply -f  crds/helmbundle/openstack/common/openstack-compute.yaml
