Working with Microservices-6: Creating the Rancher server, Running Rancher in it, and Preparing Rancher to use in Jenkins Pipeline

We will create a “Rancher server” with terraform file, and examine the structure of the terraform file. Then we will create a Kubernetes cluster for Rancher with cluster.yml file, and deploy Rancher into this cluster in the Rancher server. Finally, we will examine the created cluster structure using Rancher menus. We will use Rancher in Jenkins Pipeline later, for this we will configure Rancher to use in Jenkins Pipeline. We will install the necessary tools on the Rancher server. We will do it all step by step.

Topics we will cover:

1. Deploying a Rancher server on AWS

1. a. Prerequisites​

1. b. Download Rancher Terraform file

1. c. Rancher Terraform file’s explanation

1. d. Modifying and applying the “Rancher Server Terraform file”

2. Creating a Kubernetes cluster for Rancher

2. a. Installing kubectl

2. b. Installing eksctl (optional)

2. c. Installing RKE (Rancher Kubernetes Engine)

2. d. Creating cluster.yml file

2. e. Copying your key.pem into the Rancher server

2. f. Creating RKE Kubernetes cluster using “rke” command

3. Installing Rancher App on RKE Kubernetes Cluster using Helm

3. a. Installing Helm on Rancher Server

3. b. Creating a namespace for Rancher

3. c. Installing Rancher on RKE Kubernetes Cluster using Helm

3. d. Resetting your Rancher admin password (if you forget it)

4. Connecting to Rancher and examining the created cluster structure and Rancher menus.
