openstack-resource-controller

ORC is a set of Kubernetes controllers that manage your OpenStack tenant infrastructure.

You declare your OpenStack resource as a YAML file, you kubectl apply it and ORC provisions it on your OpenStack cloud.

Description

ORC defines each OpenStack resource type as a CRD (see ./api/v1alpha1/). Each resource type has its own controller (see ./internal/controller/). Controllers are responsible for creating and deleting resources in OpenStack when a CRD is created or deleted in their Kubernetes namespace.

State of the project

This project is currently in a prototype phase. Do NOT use in production.

Getting Started

You’ll need a Kubernetes cluster to run against. You can use KIND to get a local cluster for testing, or run against a remote cluster. Note: Your controller will automatically use the current context in your kubeconfig file (i.e. whatever cluster kubectl cluster-info shows).

Running on the cluster

1. Deploy the controller to the cluster with the image specified by IMG:

make deploy IMG=quay.io/orc/openstack-resource-controller

1. Install Instances of Custom Resources:

kubectl apply -k config/samples/

Undeploy controller

UnDeploy the controller from the cluster:

make undeploy

How to attach a port

The OpenStack API offers several options for attaching a port to a device, for example a server instance or a logical router. However in ORC, you can only define a port attachment on the receiving device. The OpenStackPort resource consequently doesn't expose the device_id field.

How it works

This project aims to follow the Kubernetes Operator pattern.

It uses Controllers, which provide a reconcile function responsible for synchronizing resources until the desired state is reached on the cluster.
