Overview

This article describes the prerequisites required to configure GKE, GAR, and GCP OpenShift in RackWare SWIFT. It covers the required Google Cloud resources, IAM permissions, service accounts, cluster requirements, and Artifact Registry configuration needed to successfully add these resources to SWIFT. 


Note: The Google Cloud service account must be created in the same project where the GKE cluster is provisioned. The service account credentials will be used later to configure GKE and GAR in SWIFT. 


Topics Covered


This article covers only the prerequisites required before configuring GKE, GAR, and GCP OpenShift in SWIFT. For configuration and discovery procedures, refer to the corresponding platform-specific KB articles .  --> Changed this sentence.


Following API needs to be enabled for your project to do this follow below steps.


Pre-requisite


- Create a Project.


1. Create a Project. To do that Click on New project.


2. Provide the name and click on create.


3. And then select the Project.



- Enable Cloud Resource Manager API


1. Search enable cloud resource manager API in search tab and click on Enable.


2. Verify the status.


- Enable Kubernetes API


1. Search Kubernetes API in search bar.


2. Verify status.



Create a Service Account


To do that follow below steps.


1. Go to IAM and User > Service account


2. Click on Create Service Account.

 

3.  Fill out the necessary account name and description details and click ‘Create and continue’ 


Required Permissions for GKE 


1. After the account is created, select roles to add for the new account, as shown below. You need to add Kubernetes engine developer, Kubernetes Engine admin, Compute Instance Admin (beta) and Compute Instance Admin (v1).  




Required Permission/Roles to add GAR


1.  Add Artifact Registry Administrator and Artifact Registry Create-on-push Repository Administrator 



Required Permission/Roles for for dynamic DR cluster creation 


1. Artifact Registry Repository Administrator , Compute Instance Admin (beta) , Compute Instance Admin (v1) , Kubernetes Engine Admin , Kubernetes Engine Developer, Compute Network Admin , Storage Admin, Service Account User 


1. Once required roles/permission has been added, then click on Done.


2. Now the new account will appear on the service accounts page. 


3. To create a key, click the three vertical dots next to the service account and select Manage keys. 


4. Click Add key and select Create new key. Select the recommended key type, and then click Create. 


5. Save the key file securely on your local machine. You will use this key when adding the GKE cluster and GAR to SWIFT. 


6. Use this JSON key to add GAR to SWIFT, and then Discover the GAR in SWIFT.


7. Use the same JSON key to add the GKE cluster to SWIFT, and then discover the GKE cluster. For more information, see Discover the GKE in SWIFT



Required permission to add GCP OpenShift


The following prerequisites are required to add a GCP OpenShift cluster to SWIFT:


1.  Use the existing Google Cloud service account key created in the prerequisite steps. No separate Google Cloud credential is required for configuring the OpenShift cluster in SWIFT.  --> Changed this


2. Create a service account for the OpenShift cluster and ensure it has the required permissions. Refer to the  How to create Service Account  KB for detailed steps.  --> Change this sentence.


3. When configuring the GCP OpenShift cluster in SWIFT, use:   --> Changed this 

    OpenShift API Server Port: 6443 



Next Steps   --> Added this after review. it will not looks abruptly ending.  


After completing the prerequisites, the required Google Cloud resources, service accounts, IAM roles, APIs, and credentials are ready for use in SWIFT.
