Running Flatcar Container Linux on AWS EC2

We will be launching three instances, with a few parameters in the User Data, and selecting our security group.

1. {% for region in site.data.alpha_channel.amis %} {% if region.name == 'us-east-1' %} Open the quick launch wizard to boot {{region.hvm}} (amd64). {% endif %} {% endfor %}
2. On the second page of the wizard, launch 3 servers to test our clustering
   • Number of instances: 3
   • Click "Continue"
3. Next, we need to specify a discovery URL, which contains a unique token that allows us to find other hosts in our cluster. If you're launching your first machine, generate one at https://discovery.etcd.io/new?size=3, configure the `?size=` to your initial cluster size and add it to the metadata. You should re-use this key for each machine in the cluster.
4. Use ct to convert the following configuration into an Ignition config, and back in the EC2 dashboard, paste it into the "User Data" field. ```yaml etcd: # All options get passed as command line flags to etcd. # Any information inside curly braces comes from the machine at boot time.

           # multi_region and multi_cloud deployments need to use {PUBLIC_IPV4}
           advertise_client_urls:       "http://{PRIVATE_IPV4}:2379"
           initial_advertise_peer_urls: "http://{PRIVATE_IPV4}:2380"
           # listen on both the official ports and the legacy ports
           # legacy ports can be omitted if your application doesn't depend on them
           listen_client_urls:          "http://0.0.0.0:2379"
           listen_peer_urls:            "http://{PRIVATE_IPV4}:2380"
           # generate a new token for each unique cluster from https://discovery.etcd.io/new?size=3
           # specify the initial size of your cluster with ?size=X
