Running Jenkins on Kubernetes - Manual Jenkins Installation Using kubectl and YAML Files (2)

milkman285

Environment:
Master Node (Ubuntu) - Compute Engine VM
Worker Node (Ubuntu) - Compute Engine VM

• Created Service successfully
• NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
  jenkins ClusterIP 10.98.228.91 8080/TCP,50000/TCP 69m

Next Step Create the Ingress Controller:
Copied the text and pasted into my jenkinsIngress.yaml file and get the following error:
The Ingress "jenkins" is invalid: spec.rules[0].http.paths[0].pathType: Required value: pathType must be specified

add pathType: Prefix...it works

However, the next step to create a StatefulSet

student@master:~$ vim jenkinsStateful.yaml
apiVersion: apps/v1
kind: StatefulSet
metadata:
name: jenkins
namespace: jenkins
spec:
selector:
matchLabels:
app: jenkins
serviceName: jenkins
replicas: 1

I get the following error:
The StatefulSet "jenkins" is invalid: spec.template.metadata.labels: Invalid value: map[string]string(nil): selector does not match template labels

Please let me know if there is something I may have missed
