= Operator Framework
The Operator Framework is a family of tools and capabilities to deliver on the customer experience described above. It is not just about writing code; testing, delivering, and updating Operators is just as important. The Operator Framework components consist of open source tools to tackle these problems:
Operator Lifecycle Manager::
Operator Lifecycle Manager (OLM) controls the installation, upgrade, and role-based access control (RBAC) of Operators in a cluster. It is deployed by default in
ifndef::openshift-rosa,openshift-rosa-hcp,openshift-dedicated[]
{product-title} {product-version}.
endif::openshift-rosa,openshift-rosa-hcp,openshift-dedicated[]
ifdef::openshift-rosa,openshift-rosa-hcp,openshift-dedicated[]
{product-title}.
endif::openshift-rosa,openshift-rosa-hcp,openshift-dedicated[]
Operator Registry::
The Operator Registry stores cluster service versions (CSVs) and custom resource definitions (CRDs) for creation in a cluster and stores Operator metadata about packages and channels. It runs in a Kubernetes or OpenShift cluster to provide this Operator catalog data to OLM.
Software Catalog::
The software catalog is a web console for cluster administrators to discover and select Operators to install on their cluster. It is deployed by default in {product-title}.
These tools are designed to be composable, so you can use any that are useful to you.
