About OperatorHub

OperatorHub is the web console interface in OpenShift Container Platform that cluster administrators use to discover and install Operators. With one click, an Operator can be pulled from its off-cluster source, installed and subscribed on the cluster, and made ready for engineering teams to self-service manage the product across deployment environments using the Operator Lifecycle Manager (OLM).

Cluster administrators can choose from catalogs grouped into the following categories:

Category Description

Red Hat Operators

Red Hat products packaged and shipped by Red Hat. Supported by Red Hat.

Certified Operators

Products from leading independent software vendors (ISVs). Red Hat partners with ISVs to package and ship. Supported by the ISV.

Red Hat Marketplace

Certified software that can be purchased from Red Hat Marketplace.

Community Operators

Optionally-visible software maintained by relevant representatives in the operator-framework/community-operators GitHub repository. No official support.

Custom Operators

Operators you add to the cluster yourself. If you have not added any Custom Operators, the Custom category does not appear in the web console on your OperatorHub.

OperatorHub content automatically refreshes every 60 minutes.

Operators on OperatorHub are packaged to run on OLM. This includes a YAML file called a ClusterServiceVersion (CSV) containing all of the CRDs, RBAC rules, Deployments, and container images required to install and securely run the Operator. It also contains user-visible information like a description of its features and supported Kubernetes versions.

The Operator SDK can be used to assist developers packaging their Operators for use on OLM and OperatorHub. If you have a commercial application that you want to make accessible to your customers, get it included using the certification workflow provided by Red Hat’s ISV partner portal at connect.redhat.com.

OperatorHub architecture

The OperatorHub UI component is driven by the Marketplace Operator by default on OpenShift Container Platform in the openshift-marketplace namespace.

OperatorHub custom resource

The Marketplace Operator manages an OperatorHub custom resource (CR) named cluster that manages the default CatalogSource objects provided with OperatorHub. You can modify this resource to enable or disable the default catalogs, which is useful when configuring OpenShift Container Platform in restricted network environments.

Example OperatorHub custom resource
apiVersion: config.openshift.io/v1
kind: OperatorHub
metadata:
  name: cluster
spec:
  disableAllDefaultSources: true (1)
  sources: [ (2)
    {
      name: "community-operators",
      disabled: false
    }
  ]
1 disableAllDefaultSources is an override that controls availability of all default catalogs that are configured by default during an OpenShift Container Platform installation.
2 Disable default catalogs individually by changing the disabled parameter value per source.
