Learn how to setup and run Rancher 2 on your own computer. Covers most of the important topics: Ingress, Workload, Pods, Service Discovery and more.
You may be in the situation like me: you have already extensively used Rancher v1.6.x but would like to migrate to Rancher v2.0.x. For those who don’t know, Rancher is a Docker Orchestration tool.
While trying to setup a development machine with Rancher 2 installed, I came accross numerous different issues. I’ve spent hours figuring out how to fix them.
This tutorial is all about sharing the tips and tricks to avoid you waste time:
If you want to increase your productivity, automate all the things from development to software testing and going in production.
You may have recognized the famous indie game Factorio used as the picture for this article. Factorio is best described as:

Step by step guide to install Rancher High-Availability (multi-nodes).
This blog post is the last part of a series of three tutorials dedicated to Rancher High-Availability.
We previously installed Rancher single-node using a external databases:
a replicated Master-Master MySQL database, a MariaDB Galera Cluster. This time we will go full HA by installing Rancher on three servers.
Pre-requisites You need an existing Rancher server (single-node) that uses an external database. You also need from 3 to 5 servers with at least 1GB RAM (8GB recommended) and a load balancer:
Step by step guide to install a MariaDB Galera Cluster for Rancher.
This blog post is the second part of a series of three tutorials dedicated to Rancher High-Availability. We previously installed a replicated Master-Master MySQL database. This time we will install a MariaDB Galera Cluster on three servers.
The trick is that we are going to use a first Rancher to install the database cluster for a second Rancher server (used in production). In the end we will have one Rancher server that manages its own database cluster!
Step by step guide to install an external and replicated MySQL Database for Rancher.
This blog post is the first part of a series of three tutorials dedicated to Rancher High-Availability. And the first step towards HA is to have a fault tolerant database.
By default Rancher comes with an embedded HSQLDB database. It’s fine for testing purpose but not suited to a production environment.
So this tutorial explains:
How to start a replicated Master - Master MySQL database using Docker, How to export Rancher data to an external database, How to start Rancher using an external database.
Simple tutorial on how to build lightweight Docker images for Java applications.
When you take a look at the Java Official Docker images, you will immediately notice how fat they are: a whopping 243MB announced for a simple Java 8 JDK base image! It takes forever to download them from a regular DSL connection here.
Usually, your Dockerfile for Java apps starts with something like:
FROM java:8 MAINTAINER ... Just try the following command: (you must have docker installed)
docker pull java:8 docker images | grep java It should output something like:
Docker makes it incredibly easy to run a variety of processes on a cluster of machines. Rancher offers container orchestration on top of Docker. Rancher allows you to manage a cluster of Docker-enabled machines. We use Rancher extensively at Octoperf to run JMeter containers on machines all over the world. We quickly faced an issue with Rancher here: container scheduling.
Rancher nodes administration UI
When you have a single machine running your docker container, everything is simple.
