Complete the following steps, depending on your installation:\n\n- Upgrade gatekeeper operator:\nThe gatekeeper operator that is installed by the gatekeeper operator policy has\n`installPlanApproval` set to `Automatic`. This setting means the operator will\nbe upgraded automatically when there is a new version of the operator. No\nfurther action is required for upgrade. If you changed the setting for `installPlanApproval` to `manual`, then you must view each cluster to manually\napprove the upgrade to the operator.\n\n- Upgrade gatekeeper without the operator:\nThe gatekeeper version is specified as part of the Gatekeeper CR in the\ngatekeeper operator policy. To upgrade the gatekeeper version:\na) Determine the latest version of gatekeeper by visiting:\nhttps://catalog.redhat.com/software/containers/rhacm2/gatekeeper-rhel8/5fadb4a18d9a79d2f438a5d9.\nb) Click the tag dropdown, and find the latest static tag. An example tag is\n\u0027v3.3.0-1\u0027.\nc) Edit the gatekeeper operator policy and update the image tag to use the\nlatest static tag. For example, you might change this line to image: \u0027registry.redhat.io/rhacm2/gatekeeper-rhel8:v3.3.0-1\u0027.\n\nRefer to https://open-policy-agent.github.io/gatekeeper/website/docs/howto/ for additional information.",

Complete the following steps, depending on your installation:\n\n- Upgrade gatekeeper operator:\nThe gatekeeper operator that is installed by the gatekeeper operator policy has\n`installPlanApproval` set to `Automatic`. This setting means the operator will\nbe upgraded automatically when there is a new version of the operator. No\nfurther action is required for upgrade. If you changed the setting for `installPlanApproval` to `manual`, then you must view each cluster to manually\napprove the upgrade to the operator.\n\n- Upgrade gatekeeper without the operator:\nThe gatekeeper version is specified as part of the Gatekeeper CR in the\ngatekeeper operator policy. To upgrade the gatekeeper version:\na) Determine the latest version of gatekeeper by visiting:\nhttps://catalog.redhat.com/software/containers/rhacm2/gatekeeper-rhel8/5fadb4a18d9a79d2f438a5d9.\nb) Click the tag dropdown, and find the latest static tag. An example tag is\n\u0027v3.3.0-1\u0027.\nc) Edit the gatekeeper operator policy and update the image tag to use the\nlatest static tag. For example, you might change this line to image: \u0027registry.redhat.io/rhacm2/gatekeeper-rhel8:v3.3.0-1\u0027.\n\nRefer to https://open-policy-agent.github.io/gatekeeper/website/docs/howto/ for additional information.",
