  4. Edit the YAML file by executing the following steps:
    1. Remove all managed fields, e.g: all from metadata, name, status, and so on.
    2. Change tag in spec.baseimagetag to the newer one.
    3. If you have individual image tags for services, ensure to update them. Also, if the value of an image tag matches baseimagetag, remove that tag.
      Refer to the following example. In the example, check the color of the rectangle and take the appropriate action:
      • Red: Remove the Items marked in red.
      • Yellow: Individual image tags.
      • Green: Update the information in baseimagetag tag.

    kubectl apply -f my_tenant.yaml
