simple-cloud-provider is a general purpose cloud provider ;-)

TL;DR

# Add simple-cloud-provider repository
helm repo add simple-cloud-provider https://dzeromsk.github.io/simple-cloud-provider/
# Deploy a Helm Release named "my-release" using the simple-cloud-provider chart

Introduction

This chart bootstraps a simple-cloud-provider deployment on a Kubernetes cluster using the Helm package manager.

Installing the Chart

To install the Chart with the Release name simple-cloud-provider:

helm repo add simple-cloud-provider https://dzeromsk.github.io/simple-cloud-provider/
helm install simple-cloud-provider simple-cloud-provider/simple-cloud-provider

The command deploys simple-cloud-provider on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.

Uninstalling the Chart

To uninstall/delete the simple-cloud-provider deployment:

helm delete simple-cloud-provider

The command removes all the Kubernetes components associated with the chart and deletes the release.

Configuration

Please refer to values.yaml for valid values and their defaults.

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

helm install simple-cloud-provider/simple-cloud-provider --name simple-cloud-provider \
  --set=service.externalPort=8080,resources.limits.cpu=200m

Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,

helm install simple-cloud-provider/simple-cloud-provider --name simple-cloud-provider -f values.yaml

Tip: You can use the default values.yaml, which is used by default, as reference

Global and namespace pools

Global pool

Any service in any namespace will take an address from the global pool {cidr,range}-global.

Namespace pool

A service will take an address based upon its namespace pool {cidr,range}-{namespace}. These would look like the following:

$ kubectl get configmap -n kube-system simple-cloud-provider -o yaml

apiVersion: v1
kind: ConfigMap
metadata:
  name: simple-cloud-provider
  namespace: kube-system
data:
  cidr-default: 192.168.0.200/29
  cidr-development: 192.168.0.210/29
  cidr-finance: 192.168.0.220/29
  cidr-testing: 192.168.0.230/29

Multiple pools or ranges

We can apply multiple pools or ranges by seperating them with commas.. i.e. 192.168.0.200/30,192.168.0.200/29 or 192.168.0.10-192.168.0.11,192.168.0.10-192.168.0.13
