Docker Swarm is a container orchestration tool that allows you to deploy and manage containers across a cluster of machines. With Docker Swarm, you can easily scale your applications, provide high availability, and simplify management.
In this tutorial, you will learn how to install Docker Swarm on nixOS Latest.
Before proceeding with the installation, make sure that you have the following:
Follow the steps below to install Docker Swarm on your nixOS Latest server:
Open the Terminal on your nixOS Latest machine.
Run the following command to install Docker Swarm:
$ sudo nix-env -iA nixos.dockerSwarm
This will download and install Docker Swarm on your nixOS Latest machine.
After installing Docker Swarm, you need to initialize it to use it. Run the following command to initialize Docker Swarm:
$ docker swarm init
This will create a new Docker Swarm cluster and initialize it with a default configuration.
If you want to add worker nodes to your Docker Swarm cluster, you can run the following command on each worker node:
$ docker swarm join --token <TOKEN> <MANAGER_IP>:<MANAGER_PORT>
Replace <TOKEN> with the token generated in Step 2 and <MANAGER_IP> with the IP address of the Docker Swarm manager node.
Once you have set up your Docker Swarm cluster, you can deploy a service to it. Run the following command to deploy a service:
$ docker service create --replicas 1 --name <SERVICE_NAME> <IMAGE_NAME>
Replace <SERVICE_NAME> with the name you want to give to your service, and <IMAGE_NAME> with the name of the Docker image you want to deploy.
Congratulations! You have successfully installed Docker Swarm on your nixOS Latest machine and deployed a service to it. With Docker Swarm, you can easily deploy and manage containers across a cluster of machines.
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!
