 Checking RBAC roles with the CLI 



1. [Access your Red Hat OpenShift cluster](https://cloud.ibm.com/docs/openshift?topic=openshift-access_cluster).
2. Check that the user is added to the RBAC role. Users are not added to a role binding if they have a higher permission. For example, if users have a cluster role and are in a cluster role binding, they are not added to each individual namespace role binding as well.

You must be a cluster administrator (Manager service access role in all namespaces) to check role bindings and cluster role bindings.

Debugging Red Hat OpenShift web console, OperatorHub, internal registry, and other components 

Virtual Private Cloud

Classic infrastructure

Red Hat OpenShift clusters have many built-in components that work together to simplify the developer experience. For example, you can use the Red Hat OpenShift web console to manage and deploy your cluster workloads, or enable 3rd-party operators from the OperatorHub to enhance your cluster with a service mesh and other capabilities.

Commonly used components include the following. If these components fail, review the following debug steps.



* Red Hat OpenShift web console in the openshift-console project
* OperatorHub in the openshift-marketplace project
* Internal registry in the openshift-image-registry project





 Step 1: Check your account setup 

Check that your IBM Cloud account is set up properly. Some common scenarios that can prevent the default components from running properly include the following:



* If your classic cluster has multiple zones, or if you have a VPC cluster, make sure that you enable [VRF or VLAN spanning](https://cloud.ibm.com/docs/openshift?topic=openshift-subnetsbasics_segmentation). To check if VRF is already enabled, run ibmcloud account show. To check if VLAN spanning is enabled, run ibmcloud oc vlan spanning get.
* If some users in the account use a multifactor authentication (MFA) like [TOTP](https://cloud.ibm.com/docs/account?topic=account-totp), make sure that you [enable MFA](https://cloud.ibm.com/docs/account?topic=account-enablemfa) for all users in the IBM Cloud account.



Enabling MFA at the user level is not supported. If MFA is enabled for some users but is not enabled for all users at the account level, authentication errors might occur.





 Step 2: Check the public gateway 



* For VPC clusters with public and private cloud service endpoints enabled:

Check that a public gateway is enabled on each VPC subnet that your cluster is attached to.

Red Hat Enterprise Linux 8 (RHEL 8)
: RHEL 8 is supported for Satellite hosts on Red Hat OpenShift version 4.9 or later and on infrastructure hosts. RHEL 8 is the recommended operating system and will become the default in the coming months.

Red Hat CoreOS (RHCOS)
: RHCOS is a minimal operating system for running containerized workloads securely and at scale. It is based on RHEL and includes automated, remote upgrade features. For more information about the key benefits of RHCOS, see [Red Hat Enterprise Linux CoreOS (RHCOS)](https://docs.openshift.com/container-platform/4.10/architecture/architecture-rhcos.html). RHCOS is supported for Satellite hosts on Red Hat OpenShift version 4.9 or later. Red Hat CoreOS hosts don't support all services. For more information, see [Supported Satellite-enabled IBM Cloud services](https://cloud.ibm.com/docs/satellite?topic=satellite-managed-services). To attach RHCOS hosts, your location must be [enabled for RHCOS](https://cloud.ibm.com/docs/satellite?topic=satellite-locationsverify-coreos-location).



 Deciding whether to enable Red Hat CoreOS support for your location 

When you create a location, you can select whether to enable Red Hat CoreOS support. Enabling Red Hat CoreOS support comes with both pros and cons. A Red Hat CoreOS enabled location unlocks more features such as minimal outbound network requirements, bring your own key (BYOK) or keep your own key (KYOK) support for encrypting cluster secrets, HTTP proxy for outbound traffic, OpenShift virtualization, and single node cluster topology. But it has a higher infrastructure requirement. On the other hand, a non Red Hat CoreOS enabled location supports a smaller feature set but can run at a smaller footprint, allowing more clusters per same capacity. For more information, see [Sizing your Satellite location](https://cloud.ibm.com/docs/satellite?topic=satellite-location-sizing).

: You can install third-party solutions in your cluster, such as [Twistlock](https://www.paloaltonetworks.com/prisma/cloud) or [StackRox](https://www.redhat.com/en/technologies/cloud-computing/openshift/advanced-cluster-security-kubernetes) to scan running containers and block malicious activities when they are detected.





 Container isolation and security 

When you run multiple apps in your cluster, you want to make sure that your workloads run isolated from each other and that you restrict the permissions of your pods within the cluster to avoid noisy neighbors or denial-of-service attacks.

What is a Red Hat OpenShift project and why should I use it?
: Red Hat OpenShift projects are a way to virtually partition a cluster and provide isolation for your deployments and the groups of users that want to move their workload onto the cluster. With projects, you can organize resources across worker nodes and also across zones in multizone clusters.
: Every cluster is set up with a set of default Red Hat OpenShift projects that include the deployments and services that are required for Red Hat OpenShift on IBM Cloud to run properly and manage the cluster. For more information, see the [service architecture](https://cloud.ibm.com/docs/openshift?topic=openshift-service-architecture).
: Cluster administrators automatically have access to these projects and can set up additional projects in the cluster. In addition, cluster users who are granted access to the cluster can create their own project and, as the creator of the project, can manage the project with administrator permissions. However, cluster users don't have access to other projects by default, unless they are granted access by a cluster administrator.

For every project that you have in the cluster, make sure to set up proper [RBAC policies](https://cloud.ibm.com/docs/openshift?topic=openshift-usersrbac) to limit access to this project, control what gets deployed, and to set proper [resource quotas and limit ranges](https://docs.openshift.com/enterprise/3.2/dev_guide/compute_resources.html).
Security updates and patches are made available by IBM Site Reliability Engineers (SREs) who continuously monitor the Linux image that is installed on your worker nodes to detect vulnerabilities and security compliance issues. For more information, see [Updating worker nodes](https://cloud.ibm.com/docs/containers?topic=containers-updateworker_node).





 Are the master and worker nodes highly available? 

The Red Hat OpenShift on IBM Cloud architecture and infrastructure is designed to ensure reliability, low processing latency, and a maximum uptime of the service. By default, every cluster in Red Hat OpenShift on IBM Cloud is set up with multiple Red Hat OpenShift master instances to ensure availability and accessibility of your cluster resources, even if one or more instances of your Red Hat OpenShift master are unavailable.

You can make your cluster even more highly available and protect your app from a downtime by spreading your workloads across multiple worker nodes in multiple zones of a region. This setup is called a [multizone cluster](https://cloud.ibm.com/docs/openshift?topic=openshift-ha_clustersmz-clusters) and ensures that your app is accessible, even if a worker node or an entire zone is not available.

To protect against an entire region failure, create [multiple clusters and spread them across IBM Cloud regions](https://cloud.ibm.com/docs/openshift?topic=openshift-ha_clustersmultiple-clusters-glb). By setting up a network load balancer (NLB) for your clusters, you can achieve cross-region load balancing and cross-region networking for your clusters.

If you have data that must be available, even if an outage occurs, make sure to store your data on [persistent storage](https://cloud.ibm.com/docs/openshift?topic=openshift-storage-plan).

For more information about how to achieve high availability for your cluster, see [High availability for Red Hat OpenShift on IBM Cloud](https://cloud.ibm.com/docs/openshift?topic=openshift-haha).

Service Mesh on Red Hat OpenShift on IBM Cloud 

This tutorial may incur costs. Use the [Cost Estimator](https://cloud.ibm.com/estimator/review) to generate a cost estimate based on your projected usage.

This tutorial walks you through how to install Red Hat OpenShift Service Mesh alongside microservices for a sample app called BookInfo in a [Red Hat OpenShift on IBM Cloud](https://cloud.ibm.com/kubernetes/catalog/about?platformType=openshift) cluster. You will also learn how to configure an Istio ingress-gateway to expose a service outside of the service mesh, perform traffic management to set up important tasks like A/B testing and canary deployments, secure your microservice communication and use of metrics, logging and tracing to observe services.

Based on the open source Istio project, Red Hat OpenShift Service Mesh adds a transparent layer on existing distributed applications. Red Hat OpenShift Service Mesh provides a platform for behavioral insight and operational control over your networked microservices in a service mesh. With Red Hat OpenShift, you can connect, secure, and monitor microservices in your Red Hat OpenShift on IBM Cloud cluster.

[Istio](https://www.ibm.com/cloud/info/istio) is an open platform to connect, secure, control and observe microservices, also known as a service mesh, on cloud platforms such as Kubernetes in Red Hat OpenShift on IBM Cloud.



 Objectives 



* Install Red Hat OpenShift Service Mesh in your cluster
* Deploy the BookInfo sample app
* Use metrics, logging and tracing to observe services
* Set up the Istio Ingress Gateway
* Perform simple traffic management, such as A/B tests and canary deployments
* Secure your mesh using mTLS
