Promote ephemeral IP to static?

Question

I have setup a compute engine VM instance with an ephemeral ip address and would like to make sure that it keeps the IP address, how can I achieve this?

Is there a way to promote the current assigned IP address to static?

I've found some info through google, but that seems to setup a new address for the server, not the current IP address.

Answer 1

According to their documentation, simply go to Networking -> External IP addresses and change the type column to "Static". I've done this myself and it simply makes the same IP address static.

NOTE: You will be charged for the IP addresses that you do not allocate to instances.
