.yaml files from Kubernetes Up and Running 2E

What

Example .yaml files from Kubernetes Up and Running, 2nd Ed, but adapted to work with Kubernets v1.17

Adapted for issues such as:

error: unable to recognize "kuard-rs.yaml": no matches for kind "ReplicaSet" in version "extensions/v1beta1"

• extensions/v1beta1 is no longer valid for apiVersion as of Kubernetes 1.16
  • https://kubernetes.io/docs/concepts/workloads/controllers/replicaset/#writing-a-replicaset-manifest

error: error validating "kuard-rs.yaml": error validating data: ValidationError(ReplicaSet.spec): missing required field "selector" in io.k8s.api.apps.v1.ReplicaSetSpec

• ReplicaSets appear to need a spec.selector now
  • https://kubernetes.io/docs/concepts/workloads/controllers/replicaset/#example

Used against:

# kubectl version -o json

Pg. 161-162 Regex issue

The example Regex given isn't even valid, it's like someone forgot to close opening [ with ] and it slipped past editors?..:

^[.[?[a-azAz0-9[([.[?[a-zA-Z0-9[+[-_a-zA-Z0-9[?)*$

But even when you fix the [s that should be ]s it still doesn't match the example valid key names on p. 162:

^[.]?[a-zAZ0-9]([.]?[a-zA-Z0-9]+[-_a-zA-Z0-9]?)*$

Here is a seemingly better working Regex:

^[^_]\.?(\w+|\d+)[-._](\w+|\d+)?$
