The Enable User Data setting allows you to pass arbitrary data into the user-data key of the DigitalOcean Metadata service. It is available in regions that are running v1.5 of our backend.

Enable User Data

You may run this command on a droplet, to retrieve the user-data that you supplied at its creation time:

curl -w "\n"

Currently, the Enable User Data setting is only required for the clustering of CoreOS droplets. For more information about using the setting with CoreOS, read this tutorial: How To Set Up a CoreOS Cluster on DigitalOcean

Eventually this will be available on other OSs as well. Check out the Cloud-Init docs for more information.

If you are planning on using CoreOS in your infrastructure, the first thing you will want to set up is a CoreOS cluster. In order for CoreOS machines to form a cluster, their etcd2 instances must be connected. In this tutorial, we will give step-by-step instructions to quickly create a 3-node CoreOS cluster on DigitalOcean.
