Kubernetes Operators Intermediate

ABOUT THIS COURSE

This course serves as an introduction to Kubernetes operators. Operators are a design pattern for building and deploying an application onto a Kubernetes cluster such that it can be used in the same manner as core Kubernetes resources. It covers the internal architecture of operators and how they fit into the larger Kubernetes ecosystem, as well as how to build basic operators using Operator-sdk. Operator-sdk is a command line tool for scaffolding operators, generating the code skeleton and Kubernetes yaml needed to deploy the operator.

This course is of interest to anyone who wants to learn how to deploy and manage applications on Kubernetes using a more Kubernetes-native style, such as Kubernetes application devlopers, architects, or operators. It is also of interest to consumers of Kubernetes applications users interested in learning how some of the applications they use work internalally. It features hands-on labs that have you constructing and deploying real operators on a live Kubernetes cluster.

• What a Kubernetes operator is
• Why you would want to use an operator

  REQUIREMENTS

  Basic familiarity with Kubernetes (i.e. creating/updating/deleting Kubernetes resources such as Pods and Services)

  The labs in this course cover the creation, deployment, and use of operators on a Kubernetes cluster. It assumes you are already familiar with the basics of Kubernetes, such as using kubectl to create resources on a Kubernetes cluster.

  The requirements for the hands-on labs are as follows:

  • Requirements for all hands-on labs
  • Operator-sdk v1.5.0+ installed
  • Kubectl v1.17.0+ installed
  • Admin access to a Kubernetes cluster. The next section covers how to provision a small cluster for free on IBM Cloud if you do not have a one already.
  • Docker v3.2.2+ installed
  • Access to a Docker image repository such as Docker Hub or quay.io
