Deploy service to the swarm

#Introduction

In this tutorial, How to Deploy service to the swarm. First, You need to install the Docker swarm cluster here.

How to Deploy service to the swarm

The simple, I will deploy the NGINX container service.

Log into Controller. Run the following command.

docker service create --name nginx_test nginx

To check service status as command below

vagrant@controller:~$ docker service ls
ID             NAME         MODE         REPLICAS   IMAGE          PORTS
44sp9ig3k65o   nginx_test   replicated   1/1        nginx:latest

We will deploy that service to all three nodes as commanded below

docker service create --replicas 3 --name nginx3nodes nginx

The result is Deploy service to the swarm as the picture below

You want to scale the service to all five nodes.

docker service scale nginx3nodes=5

We deploy Portainer on the controller to easily manage the swarm.

docker run -d -p 8000:8000 -p 9443:9443 --name=portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce

Open the browser, and go to http://SERVER:9443 (Where SERVER is the IP address of the server). you should see Swarm listed in the left navigation
