Setting up a Swarm cluster with Docker Machine and AWS CLI

We'll continue using the vfarcic/cloud-provisioning (https://github.com/vfarcic/cloud-provisioning) repository. It contains configurations and scripts that'll help us out. You already have it cloned. To be on the safe side, we'll pull the latest version:

cd cloud-provisioning

git pull

Let's create the first EC2 instance:

docker-machine create \
    --driver amazonec2 \
    --amazonec2-zone ${AWS_ZONE[1]} \
    --amazonec2-tags "Type,manager" \
    swarm-1

We specified that the Docker Machine should use the amazonec2 driver to create an instance in the zone we defined as the environment variable AWS_ZONE_1.

We made a tag with the key type and the value manager. Tag are mostly for informational purposes.

Finally, we specified the name of the instance to be swarm-1.

The output is as follows:

Running pre-create checks...

(swarm-1) Launching instance...
Waiting for machine to be running, this may take a few minutes...
