By: Viktor Farcic

Overview of this book

Building on The DevOps 2.0 Toolkit, The DevOps 2.1 Toolkit: Docker Swarm, and The DevOps 2.2 Toolkit: Self-Sufficient Docker Clusters, Viktor Farcic brings his latest exploration of the DevOps Toolkit as he takes you on a journey to explore the features of Kubernetes. The DevOps 2.3 Toolkit: Kubernetes is a book in the series that helps you build a full DevOps Toolkit. This book in the series looks at Kubernetes, the tool designed to, among other roles, make it easier in the creation and deployment of highly available and fault-tolerant applications at scale, with zero downtime. Within this book, Viktor will cover a wide range of emerging topics, including what exactly Kubernetes is, how to use both first and third-party add-ons for projects, and how to get the skills to be able to call yourself a “Kubernetes ninja.” Work with Viktor and dive into the creation and exploration of Kubernetes with a series of hands-on guides.

Attaching claimed volumes to Pods

cat pv/jenkins-pv.yml

        volumeMounts:
        - name: jenkins-home
          mountPath: /var/jenkins_home
        ...
      volumes:
      - name: jenkins-home
        persistentVolumeClaim:
          claimName: jenkins
      ...  

You'll notice that, this time, we added a new volume jenkins-home, which references the PersistentVolumeClaim called jenkins. From the container's perspective, the claim is a volume.

Let's deploy Jenkins resources and confirm that everything works as expected.

kubectl apply \
    -f pv/jenkins-pv.yml \
    --record  

The output is as follows:
