+# This is a hack to enable compression in the Ironic container used by the baremetal operator of
+# OpenShift. To use it build and push the image to your registry server:
+#
+# $ podman build -t quay.io/myuser/ironic-hack:1 -f Containerfile.ironic-hack
+# $ podman push quay.io/myuser/ironic-hack:1
+#
+# Then change the `cluster-baremetal-operator-images` configmap in the `openshift-machine-api`
+# namespace. It contains a JSON document with a `baremetalIrinic` field that needs to be changed to
+# `quay.io/myuser/ironic-hack:1`. Then delete the `metal3` deployment to force the operator to
+# recreate it with the new image:
+#
+# $ oc edit -n openshift-machine-api cluster-baremetal-operator-images
+# $ oc delete deployment -n openshift-machine-api metal3
+
+# Start from the Ironic image currently used by the baremetal operator, so that we don't need to
+# fully rebuild it.
