Docker Swarm is an orchestration tool used to manage Docker containers. It allows you to create a cluster of Docker hosts and deploy containers across them. In this tutorial, we will guide you on how to install Docker Swarm on Arch Linux.
Before starting the installation process, make sure that:
Before we start with the installation of Docker Swarm, we need to have Docker installed on the system. If you already have Docker installed, you can skip this step.
Execute the following command to install Docker:
$ sudo pacman -S docker
The first step in creating a Swarm cluster is to initialize it on the master node. In order to do that, run the following command:
$ sudo docker swarm init
This command will output a join command that you can use to add nodes to the Swarm cluster.
To add worker nodes to the Docker Swarm cluster, execute the join command that was provided by the initialization process on each node that you want to add. Execute the following command on each worker node:
$ sudo docker swarm join --token <token> <ip-address>:<port>
Replace <token> with the token generated by the init command and <ip-address>:<port> with the IP address and port of the master node.
To verify the Docker Swarm cluster, execute the following command on the master node:
$ sudo docker node ls
This command should output a list of nodes in the Swarm cluster, including the master node and any worker nodes that were added.
Congratulations! You have successfully installed Docker Swarm on Arch Linux and created a Swarm cluster. You can now start deploying containers and services across the cluster using Docker.
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!
