Retrieve Google Cloud INSTANCE_NAME

Due to trouble with my hard drive I needed to reinstall Google Cloud locally.

Unfortunately I don’t recall the name used for the INSTANCE_NAME placeholder, which is used for the connection from the terminal.

gcloud compute ssh --zone=$ZONE jupyter@$INSTANCE_NAME -- -L 8080:localhost:8080

The Google Cloud website shows me the name for the VM instance, but this VM name doesn’t work now in the terminal because it contains a - (dash).

Invalid value '“my-fastai-instance“'. Values must match the following regular expression: '[a-z](?:[-a-z0-9]{0,61}[a-z0-9])?|[1-9][0-9]{0,19}

How can I retrieve the correct INSTANCE_NAME to connect with Google Cloud again from my terminal?
