Getting Started With Swarm And Docker Machine On Aws Swarm+Docker-machine+AWS in a few commands

set some shell variables

$ export AWS_ACCESS_KEY_ID=YOUR_ACCESS_KEY_HERE
$ export AWS_SECRET_ACCESS_KEY=YOUR_SECRET_KEY_HERE
$ export AWS_DEFAULT_REGION=us-west-2

Use a local docker container to generate a swarm token

$ docker run swarm create

This will return a hash as the output e.g.:

fe0cc96a72cf04dba8c1c4aa79536ec3

Set this as a shell env var:

$ export SWARM_TOKEN=fe0cc...

Launch the swarm manager in AWS:

$ docker-machine create \
    -d amazonec2 \
    --swarm \
    --swarm-master \
    --swarm-discovery token://$SWARM_TOKEN \
    swarm-master

Launch a few nodes:

$ docker-machine create \
-d amazonec2 \
--swarm \
--swarm-discovery token://$SWARM_TOKEN \
swarm-agent-01


$ docker-machine create \
-d amazonec2 \
--swarm \
--swarm-discovery token://$SWARM_TOKEN \
swarm-agent-00

Change the active docker server to the swarm manager:

$ eval $(docker-machine env swarm-manager)

Look at the swarm:

$ docker info

run a docker container on the swarm:

$ docker run hello-world

A further test, I started up a minecraft server:

$ docker run -e EULA=TRUE  -d -p 25565:25565 itzg/minecraft-server

$ docker ps

CONTAINER ID        IMAGE                   COMMAND             CREATED             STATUS PORTS                            NAMES

4baa76223f7c        itzg/minecraft-server   "/start"            6 seconds ago       Up 6 seconds 52.26.250.197:25565->25565/tcp   swarm-agent-01/backstabbing_fermi

This was basically following the guide on: http://docs.docker.com/swarm/install-w-machine/
