terraform-rancheros-vmware

Terraform code to provision K8s clusters in vSphere with Rancher 2.x. VMs are created by cloning from a RancherOS template. A cloud-config template is used to provide nodes with static IP addresses and other configuration.

Prerequisites

Install Rancher2 Terraform provider

1. Clone the Rancher2 Terraform provider from https://github.com/rancher/terraform-provider-rancher2.
2. Build the provider binary by running make bin
3. Copy the provider binary to a local path, e.g. cp ./terraform-provider-rancher2 /usr/local/bin/

Create RancherOS template in vSphere

1. Download the RancherOS OVA appliance from: -TODO-
2. Import into vSphere ("Deploy OVF template...)
3. Mark the resulting VM as template ("Convert to template")
4. Note the name/path of the template which must be provided to Terraform

You may also use the existing template in the Fremont vCenter: vm-templates/rancheros-v1.4.0-golden.

Usage

1. Copy the terraform.tfvars.example to terraform.tfvars and adapt to match your environment
2. Specify the static IP configuration for the nodes (masters_static_ips, workers_static_ips, guest_default_gateway)
3. Adapt the cloud-config template (files/cloud-config.tpl) to your needs
4. Run terraform plan
5. Run terraform apply
