Swarm mode overview
https://docs.docker.com/engine/swarm/

Docker Engine 1.12 includes swarm mode for natively managing a cluster of Docker Engines called a swarm. Use the Docker CLI to create a swarm, deploy application services to a swarm, and manage swarm behavior.

1. Setup docker engine (docker)
root@slitaz:~# docker-machine create -d virtualbox default

root@slitaz:~# docker-machine env default
export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://192.168.99.100:2376"
export DOCKER_CERT_PATH="/root/.docker/machine/machines/default"
export DOCKER_MACHINE_NAME="default"
# Run this command to configure your shell:
# eval $(docker-machine env default)

root@slitaz:~# eval $(docker-machine env default)

root@slitaz:~# docker-machine ls

NAME    ACTIVE   DRIVER       STATE     URL                        SWARM   DOCKER    ERRORS
default   *      virtualbox   Running   tcp://192.168.99.100:2376          v1.12.3   

root@slitaz:~# docker-machine create -d virtualbox worker2
[..]

root@slitaz:~# docker-machine create -d virtualbox worker3
[..]

root@slitaz:~# docker-machine ls
NAME     ACTIVE  DRIVER       STATE     URL                       SWARM   DOCKER    ERRORS
default   *      virtualbox   Running   tcp://192.168.99.100:2376         v1.12.3   
worker2   -      virtualbox   Running   tcp://192.168.99.101:2376         v1.12.3   
worker3   -      virtualbox   Running   tcp://192.168.99.102:2376         v1.12.3   
root@slitaz:~#

2. Create a swarm
Manager / Leader : slitaz
tux@slitaz:~$ docker swarm init --advertise-addr 192.168.1.30:2377
Swarm initialized: current node (7k82hqkla3pfx2l5n1mg86nqz) is now a manager.

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

docker swarm join \
--token SWMTKN-1-0j1kwrl6tx3zujd1b5unnu6kxn3sn1zylgkueq4e10t4w8mxzc-8fzj4535sg0lttajyuw431rhq \
192.168.1.30:2377

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

tux@slitaz:~$ docker node ls

ID                          HOSTNAME  STATUS  AVAILABILITY  MANAGER STATUS
7k82hqkla3pfx2l5n1mg86nqz *  slitaz   Ready   Active        Leader

tux@slitaz:~$ docker info | grep -A16 Swarm

tux@slitaz:~$

Add nodes to the swarm
node : worker2
tux@slitaz:~$ docker-machine ssh worker2

docker@worker2:~$ docker swarm join \
>--token SWMTKN-1-0j1kwrl6tx3zujd1b5unnu6kxn3sn1zylgkueq4e10t4w8mxzc-8fzj4535sg0lttajyuw431rhq \
> 192.168.1.30:2377
This node joined a swarm as a worker.

docker@worker2:~$ docker info | grep -E 'Swarm|Node|Name|Manager|provider'
Swarm: active
NodeID: 6l6q31l3ojjanmbrkdsaydcd3
Is Manager: false
Node Address: 10.0.2.15
Name: worker2
provider=virtualbox

node : worker3
tux@slitaz:~$ docker-machine ssh worker3

docker@worker3:~$ docker swarm join \
> --token SWMTKN-1-0j1kwrl6tx3zujd1b5unnu6kxn3sn1zylgkueq4e10t4w8mxzc-8fzj4535sg0lttajyuw431rhq \
> 192.168.1.30:2377
This node joined a swarm as a worker.

docker@worker3:~$ docker info | grep -E 'Swarm|Node|Name|Manager|provider'

Is Manager: false
Node Address: 10.0.2.15

node : default
tux@slitaz:~$ docker-machine ssh default

docker@default:~$ docker swarm join \
> --token SWMTKN-1-0j1kwrl6tx3zujd1b5unnu6kxn3sn1zylgkueq4e10t4w8mxzc-8fzj4535sg0lttajyuw431rhq \
> 192.168.1.30:2377
This node joined a swarm as a worker.

docker@default:~$ docker info | grep -E 'Swarm|Node|Name|Manager|provider'
Swarm: active
NodeID: 5f0tcycycbvld9k9o2lw7zkr3

3. Four networked host machines
tux@slitaz:~$ docker node ls

ID                           HOSTNAME  STATUS  AVAILABILITY  MANAGER STATUS
5f0tcycycbvld9k9o2lw7zkr3    default   Ready   Active       
6l6q31l3ojjanmbrkdsaydcd3    worker2   Ready   Active 
7k82hqkla3pfx2l5n1mg86nqz *  slitaz    Ready   Active        Leader
d9acvt55txmtru7kx4c68vj4k    worker3   Ready   Active           
tux@slitaz:~$

4. Deploy a service to the swarm
tux@slitaz:~$ docker service create --replicas 1 --name helloworld slitaz/slitaz-base ping docker.com
cajm42r93yb27tft0e6c7qxpw

The docker service create command creates the service.
The --name flag names the service helloworld.
The --replicas flag specifies the desired state of 1 running instance.
The arguments slitaz/slitaz-base ping docker.com define the service as   

an SliTaz Linux container that executes the command ping docker.com.
tux@slitaz:~$ docker service ls
ID            NAME        REPLICAS  IMAGE               COMMAND
cajm42r93yb2  helloworld  1/1       slitaz/slitaz-base  ping docker.com

tux@slitaz:~$ docker service ps helloworld

By Docker Official Image

docker pull alpine
https://hub.docker.com/r/library/alpine/

A minimal Docker image based on Alpine Linux with a complete package index and only 5 MB in size!
[..]

What is Alpine Linux?
Alpine Linux is a Linux distribution built around musl libc and BusyBox. The image is only 5 MB in size and has access to a  package repository that is much more complete than other BusyBox based images. This makes Alpine Linux a great image base for utilities and even production applications. Read more about Alpine Linux here and you can see how their mantra fits in right at home with Docker images.
