Cilium on K3s / vSphere

Pre-requisites

In this example I’ve three ‘controlplane’ nodes created as control{0..2} and five ‘worker’ nodes worker{0..5} created running openSUSE Leap 15.2.

All IP addresses assigned using DHCP, I’m using IP lookups via govc (https://github.com/vmware/govmomi/tree/master/govc#govc) as a poor man’s DNS.

Finally, I’m using k3sup (https://github.com/alexellis/k3sup) to bootstrap the installation.

Install the first node:

Tested with openSUSE Leap 15.2 and Docker CE 19.03.

Example RKE cluster.yml:

cluster_name: cilium
ssh_agent_auth: true
ignore_docker_version: true

kubernetes_version: "v1.19.7-rancher1-1"

Configuring the Azure out-of-tree external Cloud Provider

RKE

A cluster configured using RKE needs to include the following section in cluster.yaml in order to specify that we want to use an external Cloud Provider:

cloud_provider:
  name: external
  customCloudProvider: |-
 cloudConfigType: "merge"
