Download your registry.redhat.io pull secret from the Red Hat OpenShift Cluster Manager. https://console.redhat.com/openshift/install/pull-secret
- Install podman to the localhost
- If the container has not been built yet go to containers/utilty and build the conatiner with the instructions provided.
Modify the imageset-config.yaml file to include what you need for your install. The example below will pull all base images necessary for a first time installation of OpenShift. The user can use the oc-mirror utility to pull key operators when operating in an airgapped environment.
The utility container contains all the tools necessary to successful pull RedHat Openshift operators for an airgapped installation. Run the following commands to create the ocp-images.tar
# The quay script will create the $HOME/.docker/config.json file that is necessary for the openshift mirror to query the image repositories.
bash quay.sh
#The start script will create a running utility container with volumes mounted to the $HOME/utility and $HOME and .docker directories
bash utility-start.sh
# The init will prompt the user for the quay pull secret and then run the oc-mirror based on the imageset-config.yaml
bash init.sh
#The bundle script will compile the utility conatainer along with the Sparta ansible roles and OCP utilities(oc, openshift-installer, oc-mirror & mirror registry) into a single tar file located at the tar-bundles directory
bash bundle.sh
When the init.sh script is finished it generates a ocp-images.tar with the images from the specified image set.
Running the cleanup.sh script will stop and delete the running utility container
