We have the following in GoogleCloud Kubernetes: 3 REST API Pods which take POSTs and send them to clients that are connected via Websocket.
If one of those Pods is posted on, we want to send this post to all other pods. The question is: How / Where can we find the IPs of the other Pods?
You can find the pod IP using the below and try hitting the IP but suggest you expose a service to do this.
kubectl get po -n test -o wide
NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES
pod1 1/1 Running 0 98m 10.42.0.16 worker3 <none> <none>
pod6 1/1 Running 0 87m 10.44.0.26 worker1 <none> <none> To expose a service:
kubectl expose pod/pod1 -n test --name=svc --port=80 --target-port=80
kubectl run bb --image=busybox -n test -it --rm -- sh
If you don't see a command prompt, try pressing enter.
wget -O- svc:80
Connecting to svc:80 (10.101.174.245:80)
