You are locating external IP addresses within GCP Server.
Are you working on a project where you need to retrieve external (Internet/Public) IP of respective VM instance for application?
Good news – you can quickly get them.
I am sure you would have tried running ifconfig command. And, you could notice the results contain only internal IP.
GCP and AWS, both have a friendly web interface where you can see the public IP, but if you require to get them on a server directly, then the following commands will help you.
Getting External IP on GCP VM
There are two possible ways I am aware of. The first one is using a gcloud command.
gcloud compute addresses listThe above command will show you all your project IPs. Useful for troubleshooting or have a quick review while you are logged in on VM.
Ex:
[email protected]:~# gcloud compute addresses list
NAME ADDRESS/RANGE TYPE PURPOSE NETWORK REGION SUBNET STATUS
instance-1 xx.xx.xx.xx us-west1 IN_USE
geekflare-nexus xx.xx.xx.xx INTERNAL GCE_ENDPOINT us-west1 default IN_USE
geekflare xx.xx.xx.xx us-west1 IN_USE
geekflare-tools xx.xx.xx.xx us-west1 IN_USE

curl -H "Metadata-Flavor: Google" http://metadata/computeMetadata/v1/instance/network-interfaces/0/access-configs/0/external-ipNote: if you have multiple network interface then you got to change 0 after network-interfaces to 1 or 2 accordingly.
Metadata is powerful; you can retrieve many metrics.

This can be handy for reporting and automation.
If you also need to get internal IP then use the below command.
