Usually, you can use the Red Hat OpenShift web console to get the oc login token to access your cluster. If you can't or don't want to open the Red Hat OpenShift console, choose among the following options to log in to your Red Hat OpenShift on IBM Cloud cluster by using the CLI.

Choose from the following options.



* Log in as admin:



1. Make sure that you have the [Administrator platform access role for the cluster](https://cloud.ibm.com/docs/openshift?topic=openshift-usersadd_users).
2. Set your command line context for the cluster and download the TLS certificates and permission files for the administrator.

ibmcloud oc cluster config -c <cluster_name_or_ID> --admin



* Log in with an API key: See [Using an API key to log in to Red Hat OpenShift](https://cloud.ibm.com/docs/openshift?topic=openshift-access_clusteraccess_api_key).
* Log in with IBM Cloud passcode:



1. Get the Master URL of your cluster in the output of the following command.

ibmcloud oc cluster get -c <cluster_name_or_ID>
2. In your browser, open the following IBM Cloud IAM passcode website.

https://iam.cloud.ibm.com/identity/passcode
3. Log in with your IBMid and copy the passcode.
4. Log in to your cluster with the passcode.

 Step 1: Create a Red Hat OpenShift on IBM Cloud cluster 

With Red Hat OpenShift on IBM Cloud, you have a fast and secure way to containerize and deploy enterprise workloads in clusters. Red Hat OpenShift clusters build on Kubernetes container orchestration that offers consistency and flexibility for your development lifecycle operations.

In this section, you will provision a Red Hat OpenShift on IBM Cloud cluster in one (1) zone with two (2) worker nodes:



1. Create a Red Hat OpenShift on IBM Cloud cluster from the [IBM Cloud® catalog](https://cloud.ibm.com/kubernetes/catalog/create?platformType=openshift).
2. Set the Orchestration service to 4.12.x version of Red Hat OpenShift on IBM Cloud.
3. Select your OCP entitlement.
4. Under Infrastructure choose Classic or VPC



* For Red Hat OpenShift on VPC infrastructure, you are required to have a VPC and one subnet prior to creating the Red Hat OpenShift on IBM Cloud cluster. Create or inspect a desired VPC keeping in mind the following (see instructions provided under the [Creating a standard VPC cluster](https://cloud.ibm.com/docs/openshift?topic=openshift-clustersclusters_vpcg2)):



* One subnet that can be used for this tutorial, take note of the subnet's zone and name
* Public gateway is attached to the subnet



* Select an existing Cloud Object Storage service or create one if required



5. Under Location



* For Red Hat OpenShift on VPC infrastructure



* Select a Resource group
* Uncheck the inapplicable zones
* In the desired zone verify the desired subnet name and if not present click the edit pencil to select the desired subnet name

 Preparing to update 

Review changes that you might need to make when you [update a cluster](https://cloud.ibm.com/docs/openshift?topic=openshift-update) to version 4.8. This information summarizes updates that are likely to have and impact on deployed apps when you update.



 Update before master 

The following table shows the actions that you must take before you [update the cluster master](https://cloud.ibm.com/docs/openshift?topic=openshift-updatemaster).



Changes to make before you update the master to Red Hat OpenShift 4.8

 Type Description 

 Unsupported: Deprecated and removed Red Hat OpenShift features For more information, review [Red Hat OpenShift version 4.8 deprecated and removed features](https://docs.openshift.com/container-platform/4.8/release_notes/ocp-4-8-release-notes.htmlocp-4-8-deprecated-removed-features). 
 Container runtime default security context capabilities The container runtime (for example, CRI-O) default security context capabilities have been changed to match Red Hat OpenShift Container Platform (OCP). NET_RAW and SYS_CHROOT have been removed. This brings the security behavior of containers in line with OCP. If your app requires either of these capabilities and does not list them in the container or pod securityContext, then the app must be changed to include these capabilities. If these changes are not made, your microservices might fail to start and you might see a permission denied error. Applications developed for OCP already have the necessary changes. 
 Strongswan users If you are using Strongswan in your cluster, then update at least version 2.7.11 of Strongswan before you update your cluster master to Red Hat OpenShift 4.8.
