This repository hosts an implementation of a provider for PowerVS for the OpenShift machine-api.

This provider runs as a machine-controller deployed by the machine-api-operator

The Dockerfiles use as builder in the FROM instruction which is not currently supported by the RH's docker fork (see kubernetes-sigs/kubebuilder#268). One needs to run the imagebuilder command instead of the docker build.

Note: this info is RH only, it needs to be backported every time the README.md is synced with the upstream one.

1. Deploying the cluster

   Use any existing mechanism for deploying the kubernetes cluster, e.g: kubeadm https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/

2. Deploying machine API controllers

   For development purposes the powervs machine controller itself will run out of the machine API stack. Otherwise, docker images needs to be built, pushed into a docker registry and deployed within the stack.

   To deploy the stack:

   kustomize build config | kubectl apply -f -
   

3. Deploy secret with Power VS credentials

   Power VS nodeupdate controller assumes existence of a secret file:

   apiVersion: v1
   kind: Secret
   metadata:
     name: powervs-credentials
     namespace: openshift-machine-api
   type: Opaque
   data:
     ibmcloud_api_key: FILLIN

   You can use examples/render-powervs-secrets.sh script to generate the secret:

   # Set the IBMCLOUD_API_KEY with a proper IBM Cloud API Key
   $ IBMCLOUD_API_KEY=<API_KEY> ./examples/render-powervs-secrets.sh examples/addons.yaml | kubectl apply -f -

   Go to How to create IBM Cloud API Key for creating API Key

4. Test by creating example machine

   # Update the relevant fields like serviceInstanceID, imageID, subnets, keyName etc.. 
   $ kubectl create -f examples/machine-with-user-data.yaml
   $ kubectl create -f examples/userdata.yml

1. Tear down machine-controller

   Deployed machine API plane (machine-api-controllers deployment) is (among other controllers) running machine-controller. In order to run locally built one, simply edit machine-api-controllers deployment and remove machine-controller container from it.

2. Build and run powervs actuator from outside the cluster

   $ go build -o bin/machine-controller-manager github.com/openshift/cluster-api-provider-powervs/cmd/manager

   $ .bin/machine-controller-manager --kubeconfig ~/.kube/config --logtostderr -v 5 -alsologtostderr

   If running in container with podman, or locally without docker installed, and encountering issues, see hacking-guide.
