The primary purpose of this repository is provide organization of artifacts and
manifests for a disconnected/air-gapped clusters. oc-mirror is used for
mirroring into a container registry, the included manifests mirrors the openshift
platform, additional containers, Red Hat Operators, and Red Hat Certified Operators.
At the top-level directory, we have 3 important directories:
-
cluster/ -
install/ -
mirror/
cluster/<cluster-name> is used to store copies of the agent-based installer
manifests used to build clusters. install/ is used to generate the resulting
artifacts for the agent-based installer. We copy our manifests from
cluster/<cluster-name> into install/<version>/<cluster-name> and run
openshift-install agent create image. mirror/ contains scripts and manifest
for mirroring OpenShift platform artifacts and Operators. Within mirror/, we
keep our mirroring manifests within manifests/, the metadata/ we downloaded
while mirroring the platform and operators, and store container archives within
platform/ and operators/. We keep each operator index and the platform
separate from each other for many reasons; one of which is if there’s a breaking
change in an operator index, the error doesn’t invalidate the other operator
indexes and the platform download.
