Mirantis Container Cloud (MCC) becomes part of Mirantis OpenStack for Kubernetes (MOSK)!

Now, the MOSK documentation set covers all product layers, including MOSK management (formerly Container Cloud). This means everything you need is in one place. Some legacy names may remain in the code and documentation and will be updated in future releases. The separate Container Cloud documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.

Increase storage quota for etcd

You may need to increase the default etcd storage quota that is 2 GB if etcd runs out of space and there is no other way to clean up the storage on your management or MOSK cluster.

To increase storage quota for etcd:

In the spec:providerSpec:value: section of cluster.yaml, edit the etcd:storageQuota value:

kubectl --kubeconfig <pathToManagementClusterKubeconfig> -n <projectName> edit cluster <clusterName>

Configuration example:

apiVersion: cluster.k8s.io/v1alpha1
kind: Cluster
metadata:
  name: mycluster
  labels:
    kaas.mirantis.com/provider: baremetal
spec:
  providerSpec:
    value:
      apiVersion: baremetal.k8s.io/v1alpha1
      kind: BaremetalClusterProviderSpec
      etcd:
        storageQuota: 4GB

Caution

You cannot decrease the storageQuota once set.
