Chapter 4. Creating a cluster on GCP with a Red Hat cloud account Through OpenShift Cluster Manager , you can create an OpenShift Dedicated cluster on Google Cloud Platform (GCP) using a standard cloud provider account owned by Red Hat. 4.1. Prerequisites You reviewed the introduction to OpenShift Dedicated and the documentation on architecture concepts . You reviewed the OpenShift Dedicated cloud deployment options . 4.2. Creating a cluster on GCP with a Red Hat cloud account using OpenShift Cluster Manager Through OpenShift Cluster Manager , you can create an OpenShift Dedicated cluster on Google Cloud Platform (GCP) using a standard cloud provider account owned by Red Hat. Procedure Log in to OpenShift Cluster Manager and click Create cluster . In the Cloud tab, click Create cluster in the Red Hat OpenShift Dedicated row. Under Billing model , configure the subscription type and infrastructure type: Select the Annual subscription type. Only the Annual subscription type is available when you deploy a cluster using a Red Hat cloud account. For information about OpenShift Dedicated subscription options, see Cluster subscriptions and registration in the OpenShift Cluster Manager documentation. Note You must have the required resource quota for the Annual subscription type to be available. For more information, contact your sales representative or Red Hat support. Select the Red Hat cloud account infrastructure type to deploy OpenShift Dedicated in a cloud provider account that is owned by Red Hat. Click . Select Run on Google Cloud Platform and click . On the Cluster details page, provide a name for your cluster and specify the cluster details: Add a Cluster name . Optional: Cluster creation generates a domain prefix as a subdomain for your provisioned cluster on openshiftapps.com . If the cluster name is less than or equal to 15 characters, that name is used for the domain prefix. If the cluster name is longer than 15 characters, the domain prefix is randomly generated as a 15-character string. To customize the subdomain, select the Create custom domain prefix checkbox, and enter your domain prefix name in the Domain prefix field. The domain prefix cannot be longer than 15 characters, must be unique within your organization, and cannot be changed after cluster creation. Select a cluster version from the Version drop-down menu. Select a cloud provider region from the Region drop-down menu. Select a Single zone or Multi-zone configuration. Select a Persistent storage capacity for the cluster. For more information, see the Storage section in the OpenShift Dedicated service definition. Specify the number of Load balancers that you require for your cluster. For more information, see the Load balancers section in the OpenShift Dedicated service definition. Optional: Select Enable Secure Boot for Shielded VMs to use Shielded VMs when installing your cluster. For more information, see Shielded VMs . Important To successfully create a cluster, you must select Enable Secure Boot support for Shielded VMs if your organization has the policy constraint constraints/compute.requireShieldedVm enabled. For more information regarding GCP organizational policy constraints, see Organization policy constraints . Leave Enable user workload monitoring selected to monitor your own projects in isolation from Red Hat Site Reliability Engineer (SRE) platform metrics. This option is enabled by default. Optional: Expand Advanced Encryption to make changes to encryption settings. Optional: Select Enable FIPS cryptography if you require your cluster to be FIPS validated. Note If Enable FIPS cryptography is selected, Enable additional etcd encryption is enabled by default and cannot be disabled. You can select Enable additional etcd encryption without selecting Enable FIPS cryptography . Optional: Select Enable additional etcd encryption if you require etcd key value encryption. With this option, the etcd key values are encrypted, but not the keys. This option is in addition to the control plane storage encryption that encrypts the etcd volumes in OpenShift Dedicated clusters by default. Note By enabling etcd encryption for the key values in etcd, you will incur a performance overhead of approximately 20%. The overhead is a result of introducing this second layer of encryption, in addition to the default control plane storage encryption that encrypts the etcd volumes. Consider enabling etcd encryption only if you specifically require it for your use case. Click . On the Default machine pool page, select a Compute node instance type and a Compute node count . The number and types of nodes that are available depend on your OpenShift Dedicated subscription. If you are using multiple availability zones, the compute node count is per zone. Note After your cluster is created, you can change the number of compute nodes, but you cannot change the compute node instance type in a machine pool. For clusters that use the CCS model, you can add machine pools after installation that use a different instance type. The number and types of nodes available to you depend on your OpenShift Dedicated subscription. Optional: Expand Edit node labels to add labels to your nodes. Click Add label to add more node labels and select . In the Cluster privacy dialog, select Public or Private to use either public or private API endpoints and application routes for your cluster. Click . In the CIDR ranges dialog, configure custom classless inter-domain routing (CIDR) ranges or use the defaults that are provided. Important CIDR configurations cannot be changed later. Confirm your selections with your network administrator before proceeding. If the cluster privacy is set to Private , you cannot access your cluster until you configure private connections in your cloud provider. On the Cluster update strategy page, configure your update preferences: Choose a cluster update method: Select Individual updates if you want to schedule each update individually. This is the default option. Select Recurring updates to update your cluster on your preferred day and start time, when updates are available. Note You can review the end-of-life dates in the update lifecycle documentation for OpenShift Dedicated. For more information, see OpenShift Dedicated update life cycle . Provide administrator approval based on your cluster update method: Individual updates: If you select an update version that requires approval, provide an administrator's acknowledgment and click Approve and continue . Recurring updates: If you selected recurring updates for your cluster, provide an administrator's acknowledgment and click Approve and continue . OpenShift Cluster Manager does not start scheduled y-stream updates for minor versions without receiving an administrator's acknowledgment. If you opted for recurring updates, select a preferred day of the week and upgrade start time in UTC from the drop-down menus. Optional: You can set a grace period for Node draining during cluster upgrades. A 1 hour grace period is set by default. Click . Note In the event of critical security concerns that significantly impact the security or stability of a cluster, Red Hat Site Reliability Engineering (SRE) might schedule automatic updates to the latest z-stream version that is not impacted. The updates are applied within 48 hours after customer notifications are provided. For a description of the critical impact security rating, see Understanding Red Hat security ratings . Review the summary of your selections and click Create cluster to start the cluster installation. The installation takes approximately 30-40 minutes to complete. Optional: On the Overview tab, you can enable the delete protection feature by selecting Enable , which is located directly under Delete Protection: Disabled . This will prevent your cluster from being deleted. To disable delete protection, select Disable . By default, clusters are created with the delete protection feature disabled. Verification You can monitor the progress of the installation in the Overview page for your cluster. You can view the installation logs on the same page. Your cluster is ready when the Status in the Details section of the page is listed as Ready . 4.3. steps To learn about configuring identity providers for your cluster, see Configuring Identity Providers .
