I am searching for the command to print out the podname (or hostname) when I call my echoserver (gcr.io/google_containers/echoserver. I saw that in a video, regarding loadbalancing and ingress as a proof of concept, to show which server responds when I hit the refresh button in the browser. But I cannot remember how that worked or where that was. I searched the web but didn't find any hint.
At the moment my ReplicaSet looks like this: Maybe I am missing an env variable or something like this.
apiVersion: extensions/v1beta1
kind: ReplicaSet
metadata:
name: echoserver
spec:
replicas: 1
template:
metadata:
name: echoserver
labels:
project: chapter5
service: echoserver
spec:
containers:
- name: echoserver
image: gcr.io/google_containers/echoserver:1.4
ports:
- containerPort: 8080I got it: I have to raise the Version!
With versions greater than 1.4 it works :-)
So the correct one is the actual version 1.10:
apiVersion: extensions/v1beta1
kind: ReplicaSet
metadata:
name: echoserver
spec:
replicas: 1
template:
metadata:
name: echoserver
labels:
project: chapter5
service: echoserver
spec:
containers:
- name: echoserver
image: gcr.io/google_containers/echoserver:1.10

- containerPort: 8080
