Docker Swarm is a platform for container orchestration and management. It can be installed on any platform that supports Docker. In this tutorial, we will walk through the steps to install Docker Swarm on Clear Linux Latest.
Before we begin the installation process, make sure you have the following prerequisites:
Docker Swarm can be managed using CLI tools. To download the Swarm CLI, run the following command:
sudo curl -L https://github.com/docker/swarm/releases/download/v1.2.5/swarm-1.2.5-linux-amd64.tar.gz -o /usr/local/bin/swarm.tar.gz
Extract the Swarm CLI files using the following command:
sudo tar xvf /usr/local/bin/swarm.tar.gz -C /usr/local/bin/ --strip-components=1 swarm-1.2.5-linux-amd64/swarm
Now we can create a Swarm cluster. Use the following command to create a Swarm manager:
sudo docker swarm init --advertise-addr <manager IP address>
This command will initialize the Swarm mode and create a manager node.
After running the above command, you will see an output like:
Swarm initialized: current node (lh7pks950bapup7wpk2xg9df3) is now a manager.
To add a worker to this swarm, run the following command:
docker swarm join --token SWMTKN-1-4led8zv0j4g6wztt6juik7akd2v6b0n22xogiv9c9nxsg89szd-0le7mcwzyrccyj7rz8bf28iw1 192.168.0.104:2377
To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.
The output contains a command to add a worker node to the Swarm cluster. Note down the command to add worker nodes to the cluster.
Now let's add a worker node to the Swarm cluster. Run the following command on the worker node:
sudo docker swarm join --token <worker token> <manager IP address>:2377
This command will add the worker node to the Swarm cluster.
Use the following command to verify the Swarm setup:
sudo docker node ls
This command will list all the nodes in the Swarm cluster.
Congratulations! You have now successfully installed Docker Swarm on Clear Linux Latest. Now you can use Docker Swarm to manage and orchestrate container applications.
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!
