Getting familiar with Rancher

[In addition to the providers listed above, Rancher also supports Microsoft Azure (both via VMs and Azure Kubernetes Service).]

Motivation

Rancher offers a nice GUI for Multi-Cluster Kubernetes Management.

This is an option for anyone who does not wish to use helm.

Of course, under the covers Rancher actually uses helm itself, but sometimes a graphical user interface is handy.

Rancher also offers a CLI tool.

Run with Docker

As it's possible to run Rancher with Docker, we will start with that.

First we will launch the Docker container, then we will configure some options.

Docker Run

$ docker run --name helm_rancher --restart=unless-stopped -p 80:80 -p 443:443 rancher/rancher
