I have a Deployment
with 3 replicas of a pod running the image 172.20.20.20:5000/my_app
, that is located in my private registry.
I want do a rolling-update in the deployment when I push a new latest
version of that image to my registry.
I push the new image this way (tag v3.0 to latest):
$ docker tag 172.20.20.20:5000/my_app:3.0 172.20.20.20:5000/my_app
$ docker push 172.20.20.20:5000/my_app
But nothing happens. Pods' images are not upgraded. This is my deployment definition:
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: myapp-deployment
spec:
replicas: 3
template:
metadata:
labels:
app: myapp
spec:
containers:
- name: app
image: 172.20.20.20:5000/my_app:latest
ports:
- containerPort: 8080
Is there a way to do that automatically? Should I run a command like rolling-update
like in ReplicaControllers?
