Yet Another OpenShift Install Helper

yaoih is a bash script that automates bringing up an OpenShift 4.x cluster using an installer from the OpenShift mirror.

yaoih (-r <release> | -p <version>) -c <location of cloud specific install-config.yaml> -d <install dir> -n <network config> [-x] <first delete the specified cluster>

-r release

The openshift-install release version to be used. Example: 4.4.4 or latest-4.11

-p version

The openshift-install CI stream to be used. This will pick the latest version in that stream. Example: 4.14.0-0.ci

-v version

The openshift-install CI version to be used. Example: 4.14.0-0.ci-2023-03-20-081138

Either -r or -p or -v needs to be specified or the existing binary in $INSTALLER_BIN will be used. If neither -r or -p or -v is specified and there is no existing binary, an error will be thrown. The -r takes precedence over -p or -v. -v takes precedence over -p.

-c location of cloud specific install-config.yaml

Specify the install-config.yaml that has been generated using the openshift-install create install-config command.

-d install dir

The directory that will be used by openshift-install.

-n network config file

This needs to be used only if you are trying to change network configuration. An example hybrid OVN Network manifest that will be used by openshift-install is show below:

apiVersion: operator.openshift.io/v1
kind: Network
metadata:
  creationTimestamp: null
  name: cluster
spec:
  clusterNetwork:
  - cidr: 10.128.0.0/14
    hostPrefix: 23
  externalIP:
    policy: {}
  networkType: OVNKubernetes
  serviceNetwork:
  - 172.30.0.0/16
  defaultNetwork:
    type: OVNKubernetes
    ovnKubernetesConfig:
      hybridOverlayConfig:
        hybridClusterNetwork:
        - cidr: 10.132.0.0/14
          hostPrefix: 23

-x first delete the specified cluster

Optional argument that can be used if you want to first delete the cluster before creating a new one.

INSTALLER_BIN

This is a a required environment variable that specifies the location where yaoih will download the openshift-install binary
