How to switch an IP from an instance to another with gcloud

Is there a way to “detach” a reserved internal or external IP address from a VM to assign it to another instance with the gcloud command?

I want to do this as I’m scripting with Python and want to automate this process.

Answer

Following commands might help you –

[1]. To reserve external ip addresses.

gcloud compute addresses create mysecond  
    --region=us-central1

[2]. To unset the external ip address.

gcloud compute instances delete-access-config instance-1 
 --access-config-name="External NAT"

[3]. To assign a new external ip address to a resource.

gcloud compute instances add-access-config instance-1 
--access-config-name="External NAT" --address=0.0.0.0(Your external ip address)

[4]. To list available external ip addresses in project

gcloud compute addresses list
