Thanks,
I've added:
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: worker
spec:
replicas: 1
template:
metadata:
labels:
name: worker
app: airflow
tier: worker
spec:
hostname: worker-1
Once I have done that, how can I address the worker Pod from the web Pod ?
What hostname should/can I use ?
Must I also set a subdomain ?
Thanks
