Create Infra Node Machine Sets

Quick and Dirty shell script to create machinesets as seen on the Infra Node Twitch Stream

🚨 This script has been tested on OCP 4.5

Setup

Edit this script with your variables depending on your env

clusterid="cluster2-79bxd"
region="us-east-1"
zones=(us-east-1a us-east-1b us-east-1c)
ami="ami-00e472e63fc0dbe01"

clusterid is the output of oc get -o jsonpath='{.status.infrastructureName}' infrastructure cluster
region is the AWS region your cluster is in
zones is an array of the AWS zones you want your infra node to be in.
ami is the name of the AWS ami of RHCOS

clusterid="cluster2-79bxd"
datacenter="Datacenter"
datastore="datastore1"
vspheresrv="vsphere.example.com"

clusterid is the output of oc get -o jsonpath='{.status.infrastructureName}' infrastructure cluster
datacenter is the name of your datacenter
datastore is the name of the datastore you want the VMs to be installed on
vspheresrv is the hostname of your vSphere/vCenter endpoint.

Run the script for AWS

./mk-machineset.sh

Run the script for vSphere

./mk-machineset.sh vsphere

Apply the manifest

⚠️ modify the files if you want to change the type of server.

oc apply -f ./out/

I make no guarantees for this QnD script, so YMMV. Use caution.
