Return VM to the initial state using HEAT

asked 2018-09-10 09:43:11 -0500

I use Heat to create a stack of my test environment. My template contains network, several VMs, and their configuration. Sometimes I break configuration of my VM and want to heal it (return VM to initial state - rebuild with the same image and configure). I couldn't find any information on how I can do it - the most similar is image_update_policy, when I need to specify new image.

Could you please suggest a solution or provide documentation/examples? Thank you

You can use the snapshot and restore actions in Heat to do this.

Sorry, I can't find any information about VM snapshot actions in the Heat's Template guide and cli-reference. Anyway, it is not exactly what I was looking for, because in my practice it's sometimes impossible to store all snapshots for the all VMs and it may reduce performance
