deploy cloud-init/startup script on instance(without public/floating IP) with salt-cloud for OpenStack provider

[pratik705]

Description of Issue/Question

I am trying to deploy instance on Open Stack provider without public/floating IP. As per my understanding, the "script" parameter[1] from the "profile" use ssh to copy the script to the instance. But, in my scenario, the instance doesn't have public IP and the salt-master is running in the different network. Hence, there should be some way to pass startup script to configure salt-minion on the openstack instance(minion).

Is it possible to pass "cloud-init/startup" script which will execute when the instance(without Public IP) is spawned by salt-cloud? Or is there any possible solution to run the script on instance considering this scenario?

• try to deploy instance without public/floating IP

@gtmanfred Thoughts on this one?

Script is by default salt-bootstrap.

If you want to use cloud-init, then specify a userdata_file https://docs.saltstack.com/en/latest/topics/cloud/openstack.html#userdata-file

Thanks for reply @garethgreenaway @gtmanfred .

I will test this tomorrow and update the issue.

You are also going to want to set deploy: false, so that salt-cloud doesn’t try to login to the minion that it can’t reach

@gtmanfred thanks. "userdata_file " did the trick.
