Question

Should be #cloud-config file be run after the first creation or only after the first reboot? (RancherOS)

I’m using terraform to buld the server, and it does work correctly after the first reboot, but after creation it doesn’t work. What the script is trying to do is to start a rancher service. LIke I said if I reboot the server the rancher service comes up perfectly, but it isn’t coming up after the box is first created.

The cloud-config file should be run on first boot. Though with RancherOS, there is an important caveat that can sometimes catch people up. From the Rancher docs:

When using runcmd, RancherOS will wait for all commands to complete before starting Docker. As a result, any docker run command should not be placed under runcmd. Instead, the /etc/rc.local script can be used. RancherOS will not wait for commands in this script to complete, so you can use the wait-for-docker command to ensure that the Docker daemon is running before performing any docker run commands.

So if the service depends on Docker, it’s possible that it’s not available yet. Though as it comes up after a reboot, there could be another issue here. Could you share your actual script or an example demonstrating the same behavior? It would help narrow down the problem.
