Packaging Applications and Services with Kubernetes Operators
Package applications and services for Kubernetes with the Operator framework.
Developing Operators
Operators give you a convenient way to package, deploy, manage and distribute applications for Kubernetes. The method allows you to package configuration so that users can deploy operators from a simple catalog without having to engage administrators. You can distribute operators beyond your organization using OperatorHub.io which is open to all contributions or the Red Hat OpenShift OperatorHub using Red Hat's certification process.
Operator maturity model
Conceptually, an Operator takes human operational knowledge and encodes it into software that is more easily packaged and shared with consumers. How you approach and build your Operator is up to you. Advanced Operators are designed to handle upgrades seamlessly, react to failures automatically, and not take shortcuts, such as skipping a software backup process to save time.
A Kubernetes application is both deployed on Kubernetes and managed using the Kubernetes APIs and kubectl/oc tooling. You can think of Operators as the runtime that manages this type of application on Kubernetes.
