Step 1: Update Your System

Before installing Docker Swarm, it's essential to update your system packages to the latest versions. Run the following commands:

sudo apt update && sudo apt upgrade -y

Keeping your system updated is crucial for security and performance, whether you're setting it up locally or on a VPS Windows Servers platform.

Step 2: Install Docker

Docker Swarm is built into Docker, so you need to have Docker installed first. To install Docker, run the following commands:

sudo apt install apt-transport-https ca-certificates curl software-properties-common -y
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable"
sudo apt update
sudo apt install docker-ce -y
            

After the installation, start Docker and enable it to run at boot:

sudo systemctl start docker
sudo systemctl enable docker
            

You can verify the Docker installation by checking the version:

docker --version

Step 3: Initialize Docker Swarm

To initialize Docker Swarm, run the following command:

sudo docker swarm init

This command will make the current machine a manager node in the Swarm cluster. If you plan to add worker nodes later, Docker will provide a command with a token for joining the Swarm.

Step 4: Adding Worker Nodes

To add worker nodes to the Swarm, run the command provided in the output of the previous step on the machines you want to add. It will look something like this:

sudo docker swarm join --token  :2377

Replace `` with the actual token and `` with the IP address of your manager node.

Step 5: Verify Swarm Status

You can check the status of your Swarm and see the nodes that are part of it by running the following command:

sudo docker node ls

This command will list all nodes in the Swarm and their status. You should see the manager and any worker nodes you have added.

Step 6: Deploy Services on Docker Swarm

You can now deploy services to your Swarm. For example, to deploy an Nginx service, run:

sudo docker service create --name my-nginx --replicas 3 -p 80:80 nginx

This command will create an Nginx service with 3 replicas running across your Swarm cluster.

Step 7: Access Your Services

You can access your deployed service by navigating to the IP address of any node in the Swarm in your web browser. For example, if you deployed Nginx, simply go to:

http://

Replace `` with the IP address of your manager or any worker node. This setup allows you to manage your services efficiently, whether you're running it on a local server or a Windows VPS hosting UK platform.
