Switching image catalogs

You can switch the image catalog of an already existing Cloudera Data Hub, Data Lake, or FreeIPA cluster. You may want to switch the image catalog for a cluster in order to restrict which Cloudera Runtime version can be upgraded to, or in order to move to custom images for an existing cluster.

Use the following CDP CLI commands to switch the image catalog for an existing cluster:

• FreeIPA:

  cdp environments set-catalog --environment $ENVIRONMENT_NAME --catalog $CATALOG

  Parameter	Description
  --environment	Name or CRN of the environment that holds the FreeIPA installation.
  --catalog	URL of the FreeIPA catalog to be used.

• Cloudera Data Hub:

  cdp datahub set-catalog --cluster $DATAHUB_NAME --catalog-name $CATALOG

  Parameter	Description
  --cluster	Name or CRN of the Cloudera Data Hub cluster for which you want to use the new image catalog.
  --catalog-name	Name of the image catalog to be used. The image catalog must be a JSON based catalog, and switching is only possible from catalogs that are JSON based.

• Data Lake:

  cdp datalake set-catalog --datalake $DATALAKE_NAME --catalog-name $CATALOG

  Parameter	Description
  --datalake	Name of the Data Lake for which you want to use the new image catalog.
  --catalog-name	Name of the image catalog to be used. The image catalog must be a JSON based catalog, and switching is only possible from catalogs that are JSON based.
