Thanks for the response.

I think your propose is a good walk-around. However, it doesn't seem to solve my problem. I want Heat to run a script after it finishes provisioning resources. For example, get two VMs, and then ssh to each VM and ping the other one after both VMs are up.

You can't do that directly; Heat doesn't really have a model for "run a script on the local system" (because for most deployments, you would never want this for obvious security reasons -- in a multi-tenant environment, you do not want people executing commands on the heat server). (continued...)

You could have Heat boot up an additional server, and provide that server with the appropriate script via user_data. You would probably want to use WaitCondition resources to synchronize this with the configuration of the other two servers.

Hi, I am trying to run the script in the similar way you explained but it does not take effect. Could you please advice on what the problem might be ?

This is my script: !/bin/bash echo "Hello World" > /tmp/test.txt

I checked console logs and never found these lines getting executed
