This is a lab to demonstrate running a Jenkins master on a Kubernetes cluster hosted on docker-for-desktop.
The Jenkins master is configured to use local persistent storage, which will only work with a single node cluster.
- macOS Mojave 10.14.4
- Docker CE 2.0.0.3
- Kubernetes v1.10.11
- Jenkins latest version (latest version = v2.181)
A Kubernetes cluster called docker-for-desktop is created by enabling Kubernetes in Docker preferences.
To enable the Kubernetes dashboard:
kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml
kubectl proxy &
Create a Service Account and Bearer Token
kubectl create -f admin-user.yaml
kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin-user | awk '{print $1}')
Kubernetes dashboard URL: http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/
kubectl create -f jenkins-master.yaml
The local storage path is /tmp/jenkins_home/. The persistent volume is 1GB in size.
All resources are created in a namespace called jenkins
Review the logs from the running Jenkins pod to retrive the Jenkins initial admin password
kubectl --namespace jenkins get pods
kubectl --namespace jenkins logs [pod_name]
Jenkins URL: http://localhost:30000
