Tungsten Fabric image precaching

Available since MOSK 22.3

By default, MOSK deploys image precaching DaemonSets to minimize possible downtime when updating container images. You can disable creation of these DaemonSets by setting the imagePreCaching parameter in the TFOperator custom resource to false:

spec:
  settings:
     imagePreCaching: false

When you disable imagePreCaching, the Tungsten Fabric Operator does not automatically remove the image precaching DaemonSets that have already been created. These DaemonSets do not affect the cluster setup. To remove them manually:

kubectl -n tf delete daemonsets.apps -l app=tf-image-pre-caching
