To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions. To add a worker to this swarm, run the following command:ĭocker swarm join -token SWMTKN-1-5yat7zlum78qmnlhv1vs0b0k4c42jafh5kt8xtb36eara4c5ip-490dr4yhpbe5qnic476wh90zg 10.31.45.182:2377 Swarm initialized: current node (xj5sqdpsbs5x2pgt670dft31m) is now a manager. Sample output: $ docker swarm init -advertise-addr 10.31.45.182

You should replace the Address with the IP of your manager node. The command below is used to initialize Docker Swarm Manager. In this step, we need to initialize Docker swarm mode on the manager node then we can later add the worker nodes.

Start and enable Docker sudo systemctl start dockerĪdd your user to docker group sudo usermod -aG docker $ Step 3 – Initialize Docker Swarm Cluster Sudo apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-commonĪdd Docker GPG key: curl -fsSL | sudo apt-key add -Īdd Docker repository: sudo add-apt-repository 'deb $(lsb_release -cs) stable' Install dependency packages on the hosts: sudo apt-get update We need to install Docker engine on all the hosts, manager and worker nodes. Step 2 – Install Docker CE on Debian 11 / Debian 10 10.31.45.182 managerĮnsure the hosts can reach each other via ping. sudo vim /etc/hostsĪdd the details of the nodes on each server, both the manager and the worker nodes. Step 1 – Node preparationĬonfigure the hostnames for each node in the /etc/hosts file for local resolution. This guide will discuss how to setup a Docker Swarm cluster on Debian 11 / Debian 10 hosts. You have to scale the containers manually. Docker Swarm also lacks the auto-scaling feature whereby the containers can’t auto-scale basing on monitoring and resource utilization. Unlike Kubernetes, which comes with a complete set of features like monitoring, ingress and volumes, Docker swarm comes with a much simpler state.

Install docker on debian 11
