remove unused/stopped container

Docker Compose

Docker Compose to start services from docker-compose.yml

sh
docker-compose up

compose file (without Swarm)

this is a docker-compose.yml

sh
version: "3"
services:
  web:
    # replace username/repo:tag with your name and image details
    image: hikriss/mysite:latest
    ports:
     - "5000:80"
    volumes:
     - .:/var/www

to stop services

sh
docker-compose down
Stopping trainning_web_1 ... done
Removing trainning_web_1 ... done
Removing network trainning_default

Docker swarm

create swarm cluster

the command below will create the SWarm manager node and also print how to join to this cluster on stdout.

sh
docker swarm init
Swarm initialized: current node (biquah13xnljg90b738mxv15q) is now a manager.

To add a worker to this swarm, run the following command:

    docker swarm join --token SWMTKN-1-0msistoyg1zsskn3divyrifh3i3ay8cgkw21msgknkpa6gvfse-e0bxcqztb2tzmj53itq97jlp2 192.168.65.2:2377

To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.

join worker node to Swarm manager

use output from create Swarm

check how many node to join in this cluster

sh
docker node ls
ID                            HOSTNAME            STATUS              AVAILABILITY        MANAGER STATUS

deploy stack in Swarm cluster

This cluster has only 1 machine for simplicity. the docker-compose-swarm has 2 web servers.

sh
docker stack deploy -c docker-compose-swarm.yml mycluster
Creating network mycluster_webnet
Creating service mycluster_visualizer
Creating service mycluster_web

Check deployed stack in action!

using chrome to browse to 'http://localhost:5000' to see the output of apache server

sh
hikriss@Kriss-I7:~$ curl localhost:5000
6e5b6145244a
hikriss@Kriss-I7:~$ curl localhost:5000

hikriss@Kriss-I7:~$ curl localhost:5000
27378d55c164

using chrome to browse to 'http://localhost:8080' to see the output of visualizer

Update stack

use the same command with deploy above. Swarm will be check and update only neccesary change

Check status of cluster

sh
docker stack ps mycluster
ID                  NAME                     IMAGE                             NODE                DESIRED STATE       CURRENT STATE           ERROR               PORTS

Remove stack

sh
docker stack rm mycluster
Removing service mycluster_web
Removing service mycluster_visualizer
Removing network mycluster_webnet

Remove Swarm if you need

Worker node

sh
docker swarm leave

Manager node

sh
docker swarm leave --force
