Chapter 7. How Operators work with MicroShift
You can use Operators with MicroShift to create applications that monitor the running services in your cluster. Operators can manage applications and their resources, such as deploying a database or message bus. As customized software running inside your cluster, Operators can be used to implement and automate common operations.
Operators offer a more localized configuration experience and integrate with Kubernetes APIs and CLI tools such as kubectl
and oc
. Operators are designed specifically for your applications. Operators enable you to configure components instead of modifying a global configuration file.
MicroShift applications are generally expected to be deployed in static environments. However, Operators are available if helpful in your use case. To determine an Operator’s compatibility with MicroShift, check the Operator’s documentation.
7.1. How to install Operators in MicroShift
To minimize the footprint of MicroShift, Operators are installed directly with manifests instead of using the Operator Lifecycle Manager (OLM). You can use the kustomize
configuration management tool with MicroShift to deploy an application. Use the same steps to install Operators with manifests. Read Using Kustomize manifests to deploy applications for more information about manifests.
