Deploying ROSA in STS mode

Tip The official documentation for installing a ROSA cluster in STS mode can be found here . Quick Introduction by Ryan Niksch (AWS) and Shaozen Ding (Red Hat) on YouTubeexternal link (opens in new tab) STS allows us to deploy ROSA without needing a ROSA admin account, instead it uses roles and policies with Amazon STS (secure token service) to gain access to the AWS resources needed to install and operate the cluster.

Securely exposing an application on a private ROSA cluser with an AWS Network Load Balancer

Overview Red Hat strongly recommends creating a private ROSA cluster with no inbound Internet connectivity, isolating both the cluster API and hosted applications from external access. This configuration is a key part of a multi-layered security strategy to protect clusters and workloads from external threats. However, some applications may require Internet access to support external users or partners. Even with a private cluster, you can securely expose these applications through various methods.

Configuring ROSA with HCP Private Cluster API Access

With ROSA with HCP private clusters, the AWS PrivateLink endpoint exposed in the customer’s VPC has a default security group. This security group has access to the PrivateLink endpoint that is limited to only those resources that exist within the VPC or resources that are present with an IP address associated with the VPC CIDR range. In order to grant access to any entities outside of the VPC, through VPC peering and transit gateway, you must create and attach another security group to the PrivateLink endpoint to grant the necessary access.

Prerequisites A Red Hat OpenShift on AWS (ROSA) cluster The oc CLI #logged in.

Cross-account Access using Custom OIDC Provider

Access AWS Cross Account resources using OIDC When employing ROSA, a common enterprise pattern involves establishing a cluster in a centralized AWS account while enabling development teams to manage services in their respective AWS accounts. This necessitates granting the ROSA cluster access to services residing in AWS accounts different from its own. Various approaches exist to address this challenge, but one straightforward method is to establish a secondary OIDC provider in the AWS account of the development team, enabling direct access for pods.

Customizing the console URL in ROSA

UPDATED DOCUMENT: This article has been moved to the official ROSA documentation here . Starting with ROSA 4.14.X, it is possible to modify the hostname and TLS certificate of component Routes post-install. These are the OAuth, Console, and Downloads routes. For example, the default ROSA console uses the built-in domain https://console-openshift-console.apps.<cluster_name>.<random>.p1.openshiftapps.com. You can now specify a custom domain, for example test.example.com, and the ROSA console will be available at a URL such as https://console-openshift-console.

Configure a load balancer service to use a static public IP

This guide demonstrates how to create and assign a static public IP address to an OpenShift service in Azure Red Hat OpenShift (ARO). By default, the public IP address assigned to an OpenShift service with a type of LoadBalancer created by an ARO cluster is only valid for the lifespan of that resource. If you delete the OpenShift service, the associated load balancer and IP address are also deleted. If you want to assign a specific IP address or retain an IP address for redeployed OpenShift services, you can create and use a static public IP address.

Verify Permissions for ROSA STS Deployment

To proceed with the deployment of a ROSA cluster, an account must support the required roles and permissions. AWS Service Control Policies (SCPs) cannot block the API calls made by the installer or operator roles.

ROSA - Federating Metrics to AWS Prometheus

Federating Metrics from ROSA/OSD is a bit tricky as the cluster metrics require pulling from its /federated endpoint while the user workload metrics require using the prometheus remoteWrite configuration. This guide will walk you through using the MOBB Helm Chart to deploy the necessary agents to federate the metrics into AWS Prometheus and then use Grafana to visualize those metrics. As a bonus it will set up a CloudWatch datasource to view any metrics or logs you have in Cloud Watch.

Configuring IDP for ROSA, OSD and ARO

Red Hat OpenShift on AWS (ROSA) and OpenShift Dedicated (OSD) provide a simple way for the cluster administrator to configure one or more identity providers for their cluster[s] via the OpenShift Cluster Manager (OCM) , while Azure Red Hat OpenShift relies on the internal cluster authentication operatorexternal link (opens in new tab) .

Federating Metrics to a centralized Prometheus Cluster

This document has been removed as it was written for older ROSA clusters which did not allow for custom Alert Manager configs as a way to provide a second Prometheus with a configurable Alert Manager. If you want to configure custom Alerts, you can upgrade your cluster and follow the steps found at Custom Alerts in ROSA 4.11.x . If you want to federate your metrics to a central location we recommend using one of the following:

Custom Alerts in ROSA 4.11.x

Starting with OpenShift 4.11 it is possible to manage alerting rules for user-defined projects . Similarly, in ROSA clusters the OpenShift Administrator can enable a second AlertManager instance in the user workload monitoring namespace which can be used to create such alerts. Note: Currently this is not a managed feature of ROSA. Such an implementation may get overwritten if the User Workload Monitoring functionality is toggled off and on using the OpenShift Cluster Manager (OCM).
