How to Install Rancher on Ubuntu

Rancher is an open-source container management platform that allows you to deploy and manage Kubernetes clusters easily. Installing Rancher on Ubuntu is a straightforward process that involves downloading the Rancher server image and running it as a Docker container. In this article, we will guide you through the steps required to install Rancher on Ubuntu.


Before you begin, ensure that you have the following:

  • A server running Ubuntu 18.04 or higher
  • Docker installed on the server
  • A non-root user with sudo privileges

Step 1: Install Docker

If Docker is not installed on your server, you can install it by running the following command:

sudo apt-get update
sudo apt-get install

Once the installation is complete, verify that Docker is installed correctly by running the following command:

docker --version

Step 2: Install Rancher

To install Rancher, you need to download the Rancher server image and run it as a Docker container. You can do this by running the following command:

sudo docker run -d --restart=unless-stopped -p 80:80 -p 443:443 rancher/rancher:latest

This command downloads the latest Rancher server image and runs it as a Docker container. The -d flag runs the container in detached mode, and the --restart=unless-stopped flag ensures that the container is automatically restarted if it stops unexpectedly. The -p flag maps the ports 80 and 443 of the container to the same ports on the host system, allowing you to access the Rancher server via a web browser.

Step 3: Access Rancher Web UI

Once the Rancher server is running, you can access the Rancher web UI by opening a web browser and navigating to https://<your-server-ip>. You will see the Rancher login page, where you can create a new account or log in with an existing account if you have one.

Step 4: Add Hosts

To manage your Kubernetes clusters, you need to add one or more hosts to Rancher. A host is a server or virtual machine that runs Kubernetes. You can add hosts by following these steps:

  1. Click on the Add Cluster button on the Rancher UI home page.
  2. Choose the type of cluster you want to create.
  3. Follow the instructions to configure the cluster.
  4. Once the cluster is created, click on the Add Host button to add a host to the cluster.

Step 5: Deploy Kubernetes Workloads

With Rancher and your Kubernetes clusters set up, you can now deploy your workloads to your clusters. You can do this by creating a Kubernetes deployment or by deploying a Kubernetes YAML file.

In this article, we have shown you how to install Rancher on Ubuntu and set up Kubernetes clusters using Rancher. With Rancher, you can easily manage your Kubernetes clusters and deploy your workloads without having to deal with the complexities of Kubernetes itself. We hope that this article has been helpful to you and that you can start using Rancher to manage your containerized applications.
