How to make sure that cloud-init finished running?

Hello,

is there any way to detect when cloud-init has finished running from bash?

I am using packer to create an image, and I do some init from there to get to a point where later I run puppet and other things that require my cloud-config settings to have finished running.

Is there a way to say something like:

while cloudconfigrunning; do
sleep 1
done

Ideally I would want to have a way that is platform agnostic.

now you can use cloud init cli

$ cloud-init status
status: done

See https://cloudinit.readthedocs.io/en/latest/topics/cli.html#cli-status

When cloud-init is finished running, it touches the file /var/lib/cloud/instance/boot-finished Checking for its existence is probably the simplest option. If you need to check that cloud-init finished without any error, you can also look at /var/lib/cloud/data/result.json A successful run would look like:

{
 "v1": {
  "errors": [], 
  "datasource": "DataSourceDigitalOcean"
 }
}

While an unsuccessful one (this was just a bash script with exit 1) would look like:

{
 "v1": {
  "errors": [
   "('scripts-user', RuntimeError('Runparts: 1 failures in 1 attempted commands',))"
  ], 
  "datasource": "DataSourceDigitalOcean"
 }
}

For more complex uses, the phone_home module lets you POST to an arbitrary url with data about the system.

cloud-init status -w should do it.
