fixes and container upgrades.
Note: Gatekeeper support from the Red Hat support team is limited to where
it is integrated and used with Red Hat Advanced Cluster Management

3. Solution:
The requirements to apply the upgraded images are different whether or not
you
used the operator. Complete the following steps, depending on your
installation:
* Upgrade gatekeeper operator:
The gatekeeper operator that is installed by the gatekeeper operator policy
has
`installPlanApproval` set to `Automatic`. This setting means the operator
will
be upgraded automatically when there is a new version of the operator. No
further action is required for upgrade. If you changed the setting for
`installPlanApproval` to `manual`, then you must view each cluster to
manually
approve the upgrade to the operator.
* Upgrade gatekeeper without the operator:
The gatekeeper version is specified as part of the Gatekeeper CR in the
gatekeeper operator policy. To upgrade the gatekeeper version:
a) Determine the latest version of gatekeeper by visiting:
https://catalog.redhat.com/software/containers/rhacm2/gatekeeper-rhel8/5fadb4a18d9a79d2f438a5d9.
b) Click the tag dropdown, and find the latest static tag. An example tag
is
'v3.3.0-1'.
c) Edit the gatekeeper operator policy and update the image tag to use the
latest static tag. For example, you might change this line to image:
'registry.redhat.io/rhacm2/gatekeeper-rhel8:v3.3.0-1'.
Refer to https://open-policy-agent.github.io/gatekeeper/website/docs/howto/
for additional information.
