Kubernetes configuration via Salt

Using Salt to configure Kubernetes

The Kubernetes cluster can be configured using Salt.

The Salt scripts are shared across multiple hosting providers, so it's important to understand some background information prior to making a modification to ensure your changes do not break hosting Kubernetes across multiple environments. Depending on where you host your Kubernetes cluster, you may be using different operating systems and different networking configurations. As a result, it's important to understand some background information before making Salt changes in order to minimize introducing failures for other hosting providers.

Salt cluster setup

The salt-master service runs on the kubernetes-master node.

Indexing proposal

Kubernetes Proposal - Indexing

Background

The Kubernetes cluster uses etcd as its primary data store.

High level goals:

  • Support ability to look-up an API object by something other than its key, e.g. uid
  • Support ability to look-up a list of API objects that have a field match on a particular value, e.g. label, status, etc.
