Prerequisites for installing IBM OMS Gateway Operator and IBM Sterling Intelligent Promising Operator

Edit online

A command line tool and an Operator SDK are required before you install both the OMS Gateway and IBM® Sterling Intelligent Promising operators.

Client binary

If you are connecting to Red Hat® OpenShift® Container Platform cluster, ensure you install the OpenShift CLI tool (oc) as explained in Installing the OpenShift CLI by downloading the binary.
If you are connecting to non-OpenShift Kubernetes cluster, ensure you install Kubernetes command line tool (kubectl) as explained in kubectl.

Note: oc commands are interchangeable with kubectl. Hence, if you are connected to non-OpenShift Kubernetes cluster, ensure to replace the oc commands with kubectl counterparts.

Operator SDK

Important:

This section is applicable only if you are installing both the Operators on a non-OpenShift Kubernetes cluster.
Ensure that you have administrator authority or have been granted the appropriate role-based access control (RBAC) to administer the cluster before installing the Operator Lifecycle Manager (OLM). For more information, see role-based access control good practices.
In the following steps, to install Operator SDK and OLM on a Kubernetes platform, you will be navigated to the respective websites outside of IBM, because Operator SDK and OLM are not bundled unlike Red Hat OpenShift.

Install the Operator SDK.
Ensure that you are logged in to your Kubernetes environment.
Run the following command to install OLM in your cluster:
```
operator-sdk olm install
```
- You will see the output as shown in the Installing OLM in your cluster page.
