The DevOps 2.3 Toolkit

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.

Creating storage classes

Even though kops created two StorageClasses, both are based on gp2. While that is the most commonly used EBS type, we might want to create volumes based on one of the other three options offered by AWS.

Let's say that we want the fastest EBS volume type for our Jenkins. That would be io1. Since kops did not create a StorageClass of that type, we might want to create our own.

YAML file that creates StorageClass based on EBS io1 is defined in pv/sc.yml. Let's take a quick look.

cat pv/sc.yml  

The output is as follows:

kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
  name: fast
  labels:
    type: ebs
provisioner: kubernetes.io/aws-ebs
parameters: type: io1 reclaimPolicy: Delete

We used kubernetes.io/aws-ebs as the provisioner. It is a mandatory field that determines the plugin that will be used for provisioning PersistentVolumes...
