How to install Docker Swarm on OpenSUSE Latest?

In this tutorial, we will guide you through the process of installing Docker Swarm on OpenSUSE Latest.

Prerequisites

Before starting, make sure that you have the following prerequisites:

• OpenSUSE Latest installed on your machine.
• Docker and Docker Compose installed on your machine.

Step 1: Install Docker Swarm

To install Docker Swarm, follow the steps below:

1. Open a terminal window.
2. Type the following command to install Docker Swarm:

$ sudo zypper install docker-swarm

3. Once the installation is complete, verify the installation by typing the following command:

$ docker swarm --version

This will display the version of Docker Swarm installed on your machine.

Step 2: Initialize a Docker Swarm

To initialize a Docker Swarm, follow the steps below:

1. Type the following command to create a Docker Swarm:

$ docker swarm init

2. Once the initialization is complete, you will see a command to add a worker node to the Swarm. Copy this command, as you will need it later.

Step 3: Join a Docker Swarm

To join a Docker Swarm as a worker node, follow the steps below:

1. Open a terminal window on the machine you want to join as a worker node.
2. Type the command to add the worker node to the Swarm, which you copied in the previous step.

For example, if the command was:

$ docker swarm join --token SWMTKN-1-0r95x0y6a7vqxquvdz0s7s9kwzzn05rf7viosce883mz0j48l8-4dkomwagxpfc4se4j7opii9wx 10.0.0.10:2377

3. Once the joining process is complete, you can verify that the worker node has been added to the Swarm by typing the following command on the manager node:

$ docker node ls

This will display a list of all the nodes in the Swarm.

Congratulations! You have successfully installed Docker Swarm on OpenSUSE Latest and added a worker node to the Swarm.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
