1. If you get the following error
error: unable to recognize "deployment.yaml":
no matches forkind "Deployment"in version "apps/v1beta1"
Note: Additional useful blog post here.
2. If you get this error
error: error validating "deployment.yaml": error validating data: ValidationError(Deployment.spec): missing required field "selector"in io.k8s.api.apps.v1.DeploymentSpec; #if you choose to ignore these errors, turn validation off with --validate=false
The table contains an example of the major changes in the deployment specification, the left hand side contains the new Kubernetes deployment definition and right hand side includes the older definition. The `selector` is now required.

I hope this was useful for you and let’s see what’s next?
