 done

  3. Delete the imagestreams. 

    oc delete -n openshift -f ${BASEURL}/fis-image-streams.json

  4. Remove items in the Samples Operator.

    Edit the configuration of Samples Operator: 

    oc edit configs.samples.operator.openshift.io -n openshift-cluster-samples-operator
  5. Remove the Fuse and Spring Boot 2 templates from the skippedImagestreams and skippedTemplates section.
Built-in imagestreams

Some imagestreams and templates are built-in for common use cases. These are managed by the Sample Operator, so you cannot remove them manually. You can ignore them while uninstalling.

Built-in imagestreams are configured with the samples.operator.openshift.io/managed: "true" label in the manifest, so you can verify if it is managed with the oc get and grep commands.

Example

]$ oc get is fuse7-eap-openshift -n openshift -o yaml | grep 'samples.operator.openshift.io/managed'
    samples.operator.openshift.io/managed: "true"
]$
