MicroK8s Cinder CSI

README.md

1. Create secret.yaml with openstack credentials, use template from this gist. Required actions:
   • Uncomment items needed if cloud uses a self-signed CA. Add CA in the ca.crt key.
   • If Cinder does not use the same AZs as Nova, uncomment the ignore-volume-az line.
2. Create values.yaml using the template from this gist.
   • Uncomment items needed if cloud uses a self-signed CA.
   • If Cinder does not use the same AZs as Nova, uncomment the custom storage classes options and the availability to the name of the cinder AZ.
3. Install Cinder CSI helm chart with:

microk8s helm repo add openstack https://kubernetes.github.io/cloud-provider-openstack
microk8s helm repo update
microk8s helm install --namespace kube-system cinder-csi openstack/openstack-cinder-csi -f values.yaml
