Creating a deployment using 'kubectl run' command was deprecated and is not supported anymore, starting with 1.18 version. In order to keep the example as relevant as possible, all 3 pods were kept.
Couple of changes:
- fix example to use 'kubectl create deployment' command, and scaled it up explicitly
- fix missing label for both Deployment and Service
- update label key, from 'run' to 'app', as deployments automatically add the label with this key
- update comment on how label's key could have used 'run' and 'app' values
- update pods names and internal hostnames - which are based on the replicaSet (eg. hostnames-632524106).
