I'm working on deploying a docker image in kubernetes. The first time I deployed the container, I used:

kubectl apply -f <deployment_file>.yaml

and the container was successfully deployed in a pod.

Also, the deployment_file looks something like this:

apiVersion: apps/v1beta1
kind: Deployment
metadata:
  name: publisher
spec:
  replicas: 2
  strategy:
    rollingUpdate:
      maxSurge: 1
      maxUnavailable: 1
  minReadySeconds: 300
  progressDeadlineSeconds: 900
  template:
    metadata:
      labels:
        app: publisher
    spec:
      containers:
      - name: publisher
        image: 123dev.azurecr.io/publisher:{{ci-build-number}}
        env:
          - name: ENVIRONMENT
            value: "dev"
        ports:
        - containerPort: 8080

I have defined the 'progressDeadlineSeconds' attribute in the yaml file above.

To keep a track of the deployment, I used:

kubectl rollout status deployment.v1beta1.apps/publisher

Now if I want to update the container with a new image, I can again reuse the command

kubectl apply -f <deployment_file>.yaml

to apply the update.

But what if applying the update fails due to some reason (let's say the docker image is corrupt), is there a way to automatically trigger a rollback to the previous revision when - pods status is not set to 'running' OR the execution time crosses 'pregressDeadlineSeconds'?

Till now I haven't found a way to execute a rollback automatically. Thoughts would be appreciated.
