A Step-by-Step Guide to Install Rancher on Ubuntu 22.04

Rancher is a powerful open-source container management platform that simplifies the deployment and orchestration of containers. In this step-by-step guide, we will walk you through the process of Install Rancher on Ubuntu 22.04, ensuring a smooth and efficient setup for your containerized workloads.

Prerequisites

Before diving into the installation process, make sure you have a clean installation of Ubuntu 22.04 and administrative privileges. Additionally, ensure that Docker is installed on your system, as Rancher relies on it for containerization.

Additionally, make sure your system has a minimum of 25 GB of disk space

Step 1: Update and Upgrade Ubuntu:

To ensure that your system is running the latest packages, open a terminal and run the following commands:

sudo apt update
sudo apt upgrade

Step 2: Install Docker

Rancher leverages Docker for containerization. Install Docker by running the following command:

curl https://releases.rancher.com/install-docker/23.0.6.sh | shcurl https://releases.rancher.com/install-docker/23.0.6.sh | sh

This command will fetch the Docker installation script and proceed to install Docker with a single command. Alternatively, you have the option to follow the official Docker installation guide for the manual installation process.

Ensure that Docker starts automatically after a reboot and verify its status with the following commands:

sudo systemctl enable docker
sudo systemctl start docker
sudo systemctl status docker

Reboot Ubuntu.

Step 3: Install Rancher on Ubuntu 22.04

Now, let’s install Rancher on your Ubuntu 22.04 system. Run the following Docker command to pull the latest Rancher docker image and run Docker container:

sudo docker pull rancher/rancher
sudo docker run -d --name=rancher --restart=unless-stopped -p 80:80 -p 443:443 --privileged rancher/rancher

This command will download the Rancher server image and start the Rancher server container. The -p flag is used to map the container’s ports to the host machine.

Step 4: Access Rancher Web Interface

Once the Rancher server container is running, open your web browser and navigate to:

https://<your-server-ip>

You will be greeted with the Rancher login page.

To obtain the “Bootstrap Password,” identify your container ID using the docker ps command:

and then execute:

docker logs container-id 2>&1 | grep "Bootstrap Password:"
