Updating the Access Key (AK/SK) for a Parallel File System Volume

If your service containers in a self-managed cluster use an OBS parallel file system for data storage and access, you must manually restart them whenever the volume's access key is changed to apply the new key. This process may interrupt services.

CCI can automatically apply the updated access key (AK/SK) of parallel file system volumes. After the access key of a volume are updated, CCI automatically detects the change and applies the new key to all affected workloads. This eliminates the need to manually restart these workloads, ensuring service continuity during the key update.

Update the Access Key (AK/SK)

  1. Log in to the CCI 2.0 console.
  2. In the navigation pane, choose Configuration Center. On the Secrets tab, locate the secret to be updated and click Edit YAML in the Operation column.
  3. Modify the AK/SK and then click OK.

    Ensure that the updated access key is valid and has the permissions to access the corresponding parallel file system volume. Otherwise, the workload cannot access the mounted parallel file system.
