In order to install Rancher in your cluster, Your cluster needs to have the following:

  1. Storage Configured (e.g. using NFS Storage Provisioner)
  2. Ingress Controller (e.g. using Nginx or Traefik)
  3. Cert-Manager (see Setup Cert Manager)

Steps:

  1. Setup Helm
  2. Install Rancher

1. Setup Helm

Just download the binary for your OS and add it to your system Path variable https://github.com/helm/helm/releases

The full instruction for installing Helm is available here https://v3.helm.sh/docs/intro/install/

2. Install Rancher

Add the Racncher Helm Chart Repository

# Add Chart

helm repo add rancher-latest https://releases.rancher.com/server-charts/latest

Create the rancher namespace

kubectl create namespace rancher

You can install rancher in one of two ways

  1. Using LetsEncrypt to generate SSL Certificates
  2. Using your own SSL Certificate

1. Using LetsEncrypt

# Install Rancher using LetsEncrypt
helm install rancher rancher-latest/rancher --namespace rancher --set hostname=rancher.hostname.com --set ingress.tls.source=letsEncrypt --set [email protected]

2. Using your own Certificates

# Install Rancher using Your Own Certs
# Make sure the tls Cert is configured in rancher namespace
kubectl create secret tls tls-rancher-ingress --cert=tls-dev-io.crt --key=tls-dev-io.key --namespace rancher

# Install using the Certs
helm install rancher rancher-latest/rancher --namespace rancher --set hostname=rancher.hostname.com --set ingress.tls.source=tls-rancher-ingress
