Conclusion

Building a Pet Store Operator

Learn to build an operator from scratch and extend the Kubernetes API.

We'll cover the following

Initializing the new operator

In this lesson, we will build on the background information of CRDs, operators, and controllers to implement our own operator. This operator will have only one CRD, Pet, and only one controller to reconcile those Pet resources. The desired state of Pet will be reconciled to our pet store service, which we used in previous sections.
