RKE2 Cluster on VMware vSphere

The motivation of this project is to provide a simple setup to easily install a 3 node rke2 cluster.

Architecture

Cluster infrastructure is running on 3 Oracle Linux 8 VMs and all of them are running as a Control Plane node.

These nodes have additional disk to setup ZFS Local PV from OpenEBS project.

Prerequisites

Create an OL8 based template Provide enough storage and resources on your vSphere cluster.

Cureently this method installs all three nodes on a single machine.

Configuration

export vsphere_server="<vcsa address>"
export vsphere_user="<User with privileges to create VM>"
export vsphere_password="<PW>"
export vsphere_dc="Datacenter which will be used to host the machines"
export ansible_vault_pw="It could be a dummy one"


cat > .auto.tfvars <<EOF
vsphere_server = ${vsphere_server}
vsphere_user = ${vsphere_user}
vsphere_password = ${vsphere_password}
vsphere_dc = ${vsphere_dc}
ansible_vault_pw = ${ansible_vault_pw}
EOF

Deployment

terraform init
terraform plan -out .tfplan
terraform apply ".tfplan"
