Updating SCM with Custom Non-Root User ID and Group ID

To update SCM with custom non-root user ID and group ID:

Go to the new SCM Helm chart directory, typically the cloudmanager directory created by the installer.

Update the securityContext section in values.yaml, as follows:

securityContext:
  runAsGroup: 0
  runAsUser: <scm_run_as_user>
  fsGroup: <scm_fs_group>
  privileged: false

Mount the SCM NFS server to an instance where the file system is accessible:
```
sudo mount -t nfs <FILESYSTEM_HOST>:/<export_path> <mount_directory> -o nolock
```
Change ownership of the SCM base directory.
```
cd <mount_directory>
sudo chown -R <scm_run_as_user>:0 <SCM_NAMESPACE_IN_UPPERCASE>
sudo chmod -R g+rwx <SCM_NAMESPACE_IN_UPPERCASE>
```
In the above command <scm_run_as_user> is the user ID specified in securityContext.runAsUser and the group owner must be 0.
Run the Helm upgrade from the SCM Helm chart directory:
```
cd <cloudmanager helmchart directory>
helm upgrade <releaseName> . -n <namespace>
```
In the above command <releaseName> is the SCM Helm chart instance identifier and <namespace> is the SCM namespace.
Verify that the SCM pod is running.
```
kubectl get pods -n <namespace>
```
