Outputs the hostnames and IP addresses of all or a given regex filter of Google Compute Engine hosts
|
|
in the current project in a format that can be piped or copied into /etc/hosts
|
|
|
|
Useful to doing direct SSH to hosts and especially for Ansible to speed up not going through IAP which is slow
|
|
|
|
|
|
Output:
|
|
|
|
<ip> <vm_hostname>
|
|
<ip> <vm_hostname2>
|
