# ceph-csi-cephfs The ceph-csi-cephfs chart adds cephFS volume support to your cluster. ## Install from release repo Add chart repository to install helm charts from it ```console helm repo add ceph-csi https://ceph.github.io/csi-charts ``` ## Install from local Chart we need to enter into the directory where all charts are present ```console cd charts ``` **Note:** charts directory is present in root of the ceph-csi project ### Install Chart To install the Chart into your Kubernetes cluster - For helm 2.x ```bash helm install --namespace "ceph-csi-cephfs" --name "ceph-csi-cephfs" ceph-csi/ceph-csi-cephfs ``` - For helm 3.x Create the namespace where Helm should install the components with ```bash kubectl create namespace ceph-csi-cephfs ``` Run the installation ```bash helm install --namespace "ceph-csi-cephfs" "ceph-csi-cephfs" ceph-csi/ceph-csi-cephfs ``` After installation succeeds, you can get a status of Chart ```bash helm status --namespace "ceph-csi-cephfs" "ceph-csi-cephfs" ``` ### Upgrade Chart If you want to upgrade your Chart, use the following commands. ```bash helm repo update ceph-csi helm upgrade --namespace ceph-csi-cephfs ceph-csi-cephfs ceph-csi/ceph-csi-cephfs ``` For upgrading to a specific version, provide the flag `--version` and the version. **Do not forget to include your values**, if they differ from the default values. We recommend not to use `--reuse-values` in case there are new defaults AND compare your currently used values with the new default values. ### Enabling encryption support To enable FSCrypt support, you will need to include the KMS configuration in `encryptionKMSConfig`. Here is a `values.yaml` example using a Kubernetes secret (`kubernetes` KMS) ```yaml encryptionKMSConfig: encryptionKMSType: "metadata" secretName: "cephfs-encryption-passphrase" # This secret needs to contain the passphrase as the key `encryptionPassphrase` secretNamespace: "my-namespace" storageClass: encrypted: true encryptionKMSID: kubernetes ``` #### Least privilege secret access If you use the `metadata` and let RBAC created by the chart, permissions will be given to access **only** the secret referenced in the `encryptionKMSConfig`. This is something important to keep in mind, as a manual change to the config to point to another secret or add further KMS config will not be authorized. If you wish to give CephCSI a global secret access to the cluster, you may set `rbac.leastPrivileges` to `false`, and permissions will be granted globally via a *ClusterRole*. #### Known Issues Upgrading - When upgrading to version >=3.7.0, you might encounter an error that the CephFS CSI Driver cannot be updated. Please refer to [issue](https://github.com/ceph/ceph-csi/issues/3397) for more details. This is due to the CSIDriver resource not being updatable. To work around this you can delete the CSIDriver object by running: ```bash kubectl delete csidriver cephfs.csi.ceph.com ``` Then rerun your `helm upgrade` command. ### Delete Chart If you want to delete your Chart, use this command - For helm 2.x ```bash helm delete --purge "ceph-csi-cephfs" ``` - For helm 3.x ```bash helm uninstall "ceph-csi-cephfs" --namespace "ceph-csi-cephfs" ``` If you want to delete the namespace, use this command ```bash kubectl delete namespace ceph-csi-cephfs ``` ### Configuration The following table lists the configurable parameters of the ceph-csi-cephfs charts and their default values. | Parameter | Description | Default | | ---------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------- | | `rbac.create` | Specifies whether RBAC resources should be created | `true` | | `rbac.leastPrivileges` | Specifies whether RBAC resources should be created with a restricted scope when supported (only secrets supported currently) | `true` | | `serviceAccounts.nodeplugin.create` | Specifies whether a nodeplugin ServiceAccount should be created | `true` | | `serviceAccounts.nodeplugin.name` | The name of the nodeplugin ServiceAccount to use.
