OpenShift Appliance Builder Example

The purpose of this repo is to demonstrate how to build an openshift-appliance using a local registry cache.

Overview

Files

The following files are required to get this to work.

podman-bin.sh

This file lets the mirror config be passed along to the second podman run in podman. You don't need to modify this file.

registries.conf

This file sets the repo mirrors. At a minimum you need to add entries for quay.io and registry.redhat.io. Depending on what operators are being bundled, you many need to add additional entires for those repos.

appliance-confg.yaml

A very simple appliance-config.yaml is included for demo purposes. You will need to update the pullSecret parameter to include authentication for your local mirror repo. The sample file has an example. You also need to include quay.io as the process uses oc image extract which ignore the mirror settings. oc image extract is only used for the initial image ~1 GB.

Run It.

This example assumes you've cloned this repo to your home directory.

cd ~
git clone https://github.com/themoosman/openshift-appliance-builder-proxy.git

Create the Image

sudo podman run --rm -it --pull newer --privileged --net=host \
-v /home/kmoos/openshift-appliance-builder-proxy/podman-bin.sh:/root/.local/bin/podman:Z \
-v /home/kmoos/openshift-appliance-builder-proxy/data:/assets:Z \
-v /home/kmoos/openshift-appliance-builder-proxy/registries.conf:/etc/containers/registries.conf:ro \
quay.proxy.example.com/registry_redhat_proxy/assisted/agent-preinstall-image-builder-rhel9:1.0.1 \
build --log-level=debug
