Deploy OpenShift 4.6 and later using static IP addresses for CoreOS nodes. The ignition module will inject code into the cluster that will automatically approve all node CSRs. This runs only once at cluster creation. You can delete the ibm-post-deployment namespace once your cluster is up and running.
NOTE: This requires OpenShift 4.6 or later to deploy, if you're looking for 4.5 or earlier, take a look at the pre-4.6 branch
NOTE: Requires terraform 0.13 or later.
OpenShift 4.6 User-Provided Infrastructure
- DNS needs to be configured for external cluster access.
- api.
cluster_id.base_domainpoints toopenshift_api_virtualip - *.apps.
cluster_id.base_domainpoints toopenshift_ingress_virtualip - Point both of those DNS A or CNAME records to your LoadBalancers
- api.
- CoreOS OVA must be uploaded to vCenter as a template.
