Editing cloud-config with CoreOS

Posted October 22, 2014 4k views

There are several tutorials on how to setup and initialize a CoreOS cluster with cloud-init, however I can’t find any on how to edit cloud-config after a cluster has been set up.

The cluster is running and I would like to add a few options and parameters now that I’m more familiar with the system.

Restarting each droplet in the cluster to activate the new options is not an issue. Just would like some way of altering the configuration.

You can’t edit the user-data to change cloud-config for an existing droplet. You can add new droplets with a different cloud-config file to the existing cluster as long as you continue using the same discovery URL. Though it may just be easier to create a new cluster.

    How would a different cloud-config affect the droplets already in the cluster? It seems there are some options that I think would need all droplets to be on the same page.
