One of the node will be acting as manager and other two nodes will be acting as workers. We will be going through the step by step instructions to setup docker, docker compose and will see on how to add the nodes 1, 2 and 3 in to the docker swarm, This will be a part 1 video, we will be using this docker swarm setup for our upcoming videos to deploy services in the docker swarm. If you have not subscribed to my channel kindly do so and provide your comments.


To enable docker swarm, you need to run the command docker swarm init. This will initialize the docker swarm and will provide the address to add other nodes as worker. we need to run the command on other nodes to add those nodes as worker nodes . In some cases docker swarm init may not work. Mostly if you are running the host machines from cloud. In those cases you need to also use, hyphen hyphen advertise hyphen a d d r ip address of your manager node, along with docker swarm init command.
