Kubernetes Cloud Controller Manager for Utho

The Utho Cloud Controller Manager (ccm) provides a fully supported experience of Utho features in your Kubernetes cluster.

• Node resources are assigned their respective Utho instance hostnames, Region, PlanID and public/private IPs.
• Utho LoadBalancers are automatically deployed when a LoadBalancer service is deployed.

Getting Started

More information about running Utho cloud controller manager can be found here

Examples can also be found here

Note: do not modify utho load-balancers manually

When a load-balancer is created through the CCM (Loadbalancer service type), you should not modify the load-balancer. Your changes will eventually get reverted back due to the CCM validating state.

Any changes to the load-balancer should be done through the service object.

Development

Go minimum version 1.23

The utho-cloud-controller-manager uses go modules for its dependencies.

Building the Docker Image

Since the utho-cloud-controller-manager is meant to run inside a kubernetes cluster you will need to build the binary to be Linux specific.

or by using our Makefile

make build VERSION=0.1.0

This will build the binary, docker image.

Deploying to a kubernetes cluster

You will need to make sure that your kubernetes cluster is configured to interact with a external cloud provider

More can be read about this in the Running Cloud Controller

To deploy the versioned CCM that Utho providers you will need to apply two yaml files to your cluster which can be found here.

• Secret.yml will take in the region ID in which your cluster is deployed in and your API key.

• latest.yml is a preconfigured set of kubernetes resources which will help get the CCM installed.
