( Google Cloud platform) I accidentally set up a firewall inside the Linux VM

Question

I cannot access the ssh console at all. Is there a way for me to download the disk inside the cloud platform?

This article might help you on recovering from UFW lockout. Steps are similar for other firewalls. The simplest method is to create a startup script and reboot your instance. The steps to mount the disk on another VM are also covered. https://www.jhanley.com/google-cloud-recovering-from-ufw-lockout/ — John Hanley, Jul 31 '21 at 19:05

You should be able to get onto the VM through a serial console:

Alternatively, mount the disk on another, VM revert the change and then put it back on the original VM.
