Custom Domains for ROSA Applications

Expose your applications on the internet with clean, secure URLs

When deploying applications on Red Hat OpenShift Service on AWS (ROSA), you often want users to access them through a familiar, branded URL — not a long, machine-generated one. That’s where custom domains come in.

Let’s simplify what this means and how to set it up — no code involved.

🔎 What is a Custom Domain?

By default, when you deploy an app in ROSA, it’s given a generic address like:

myapp-default.apps.randomstring.openshiftapps.com

This works, but it’s not ideal for users or businesses.

A custom domain lets you use something user-friendly and on-brand, like:

app.mycompany.com

✅ Why You Should Use Custom Domains

Here’s why it’s worth doing:

Better branding: Your domain matches your company name.

User-friendly: Easier to remember, type, and share.

Improved security: Use your own SSL certificates and HTTPS.

Professional image: Especially important for customer-facing apps.

🛠️ What You Need

To use a custom domain with ROSA, you’ll need:

A registered domain name (like mycompany.com)

Access to your DNS provider (like GoDaddy, AWS Route 53, Cloudflare)

Your ROSA cluster’s public hostname or IP (your cloud/infra team usually provides this)

🚀 Steps to Set Up (In Simple Terms)

Pick your subdomain Choose something clean like apps.mycompany.com or portal.mycompany.com.

Create a wildcard DNS entry Go into your domain provider and point everything under that subdomain (like *.apps.mycompany.com) to your ROSA cluster’s external address.

Ask your platform team to update the route Your app’s route needs to use the new custom domain. This part’s handled inside OpenShift, and your DevOps team can take care of it.

Secure it with HTTPS You’ll want SSL certificates for your domain to ensure secure access. Your team can use Let’s Encrypt or upload your organization’s certificates.

🔐 Secure Your Routes

Always make sure your applications are using HTTPS, not HTTP. This protects your users and builds trust. ROSA supports different types of secure connections — your team will pick what fits your setup best.

👍 Best Practices

Use short, clear subdomains for different apps (e.g., api.mycompany.com, login.mycompany.com)

Keep SSL certificates updated automatically

Test your domain before going live

Monitor for downtime or DNS issues

💡 Final Thought

Using custom domains in ROSA is a small configuration change that delivers big benefits: it makes your applications look polished, trustworthy, and easier to use. Whether you're building internal tools or public platforms, this step moves you closer to production-ready.

Kubernetes Cluster Management at Scale: Challenges and Solutions

As Kubernetes has become the cornerstone of modern cloud-native infrastructure, managing it at scale is a growing challenge for enterprises. While Kubernetes excels in orchestrating containers efficiently, managing multiple clusters across teams, environments, and regions presents a new level of operational complexity.

In this blog, we’ll explore the key challenges of Kubernetes cluster management at scale and offer actionable solutions, tools, and best practices to help engineering teams build scalable, secure, and maintainable Kubernetes environments.

Why Scaling Kubernetes Is Challenging

Kubernetes is designed for scalability—but only when implemented with foresight. As organizations expand from a single cluster to dozens or even hundreds, they encounter several operational hurdles.

Key Challenges:

1. Operational Overhead

Maintaining multiple clusters means managing upgrades, backups, security patches, and resource optimization—multiplied by every environment (dev, staging, prod). Without centralized tooling, this overhead can spiral quickly.

2. Configuration Drift

Cluster configurations often diverge over time, causing inconsistent behavior, deployment errors, or compliance risks. Manual updates make it difficult to maintain consistency.

3. Observability and Monitoring

Standard logging and monitoring solutions often fail to scale with the ephemeral and dynamic nature of containers. Observability becomes noisy and fragmented without standardization.

4. Resource Isolation and Multi-Tenancy

Balancing shared infrastructure with security and performance for different teams or business units is tricky. Kubernetes namespaces alone may not provide sufficient isolation.

5. Security and Policy Enforcement

Enforcing consistent RBAC policies, network segmentation, and compliance rules across multiple clusters can lead to blind spots and misconfigurations.

Best Practices and Scalable Solutions

To manage Kubernetes at scale effectively, enterprises need a layered, automation-driven strategy. Here are the key components:

1. GitOps for Declarative Infrastructure Management

GitOps leverages Git as the source of truth for infrastructure and application deployment. With tools like ArgoCD or Flux, you can:

Apply consistent configurations across clusters.

Automatically detect and rollback configuration drifts.

Audit all changes through Git commit history.

Benefits:

·       Immutable infrastructure

·       Easier rollbacks

·       Team collaboration and visibility

2. Centralized Cluster Management Platforms

Use centralized control planes to manage the lifecycle of multiple clusters. Popular tools include:

Rancher – Simplified Kubernetes management with RBAC and policy controls.

Red Hat OpenShift – Enterprise-grade PaaS built on Kubernetes.

VMware Tanzu Mission Control – Unified policy and lifecycle management.

Google Anthos / Azure Arc / Amazon EKS Anywhere – Cloud-native solutions with hybrid/multi-cloud support.

Benefits:

·       Unified view of all clusters

·       Role-based access control (RBAC)

·       Policy enforcement at scale

3. Standardization with Helm, Kustomize, and CRDs

Avoid bespoke configurations per cluster. Use templating and overlays:

Helm: Define and deploy repeatable Kubernetes manifests.

Kustomize: Customize raw YAMLs without forking.

Custom Resource Definitions (CRDs): Extend Kubernetes API to include enterprise-specific configurations.

Pro Tip: Store and manage these configurations in Git repositories following GitOps practices.

4. Scalable Observability Stack

Deploy a centralized observability solution to maintain visibility across environments.

Prometheus + Thanos: For multi-cluster metrics aggregation.

Grafana: For dashboards and alerting.

Loki or ELK Stack: For log aggregation.

Jaeger or OpenTelemetry: For tracing and performance monitoring.

Benefits:

·       Cluster health transparency

·       Proactive issue detection

·       Developer fliendly insights

5. Policy-as-Code and Security Automation

Enforce security and compliance policies consistently:

OPA + Gatekeeper: Define and enforce security policies (e.g., restrict container images, enforce labels).

Kyverno: Kubernetes-native policy engine for validation and mutation.

Falco: Real-time runtime security monitoring.

Kube-bench: Run CIS Kubernetes benchmark checks automatically.

Security Tip: Regularly scan cluster and workloads using tools like Trivy, Kube-hunter, or Aqua Security.

6. Autoscaling and Cost Optimization

To avoid resource wastage or service degradation:

Horizontal Pod Autoscaler (HPA) – Auto-scales pods based on metrics.

Vertical Pod Autoscaler (VPA) – Adjusts container resources.

Cluster Autoscaler – Scales nodes up/down based on workload.

Karpenter (AWS) – Next-gen open-source autoscaler with rapid provisioning.

Conclusion

As Kubernetes adoption matures, organizations must rethink their management strategy to accommodate growth, reliability, and governance. The transition from a handful of clusters to enterprise-wide Kubernetes infrastructure requires automation, observability, and strong policy enforcement.

By adopting GitOps, centralized control planes, standardized templates, and automated policy tools, enterprises can achieve Kubernetes cluster management at scale—without compromising on security, reliability, or developer velocity.

Deploy and Manage Policies for Multiple Clusters with RHACM

In today’s cloud-native landscape, most organizations don’t rely on a single Kubernetes cluster anymore — they run multiple clusters across cloud, on-prem, and edge environments. While this brings flexibility, it also introduces complexity: How do you consistently manage security, compliance, and operational policies across all those clusters?

That’s where Red Hat Advanced Cluster Management for Kubernetes (RHACM) comes in. Specifically, RHACM's governance and policy management features are built to help teams define, enforce, and monitor policies across multiple clusters — from a single place.

🌐 Why Policy Governance Matters in Multicluster Environments

Managing multiple clusters isn’t just about scaling workloads — it’s about maintaining control. Without a unified way to govern them, you risk:

Security drift between clusters

Manual configuration errors

Inconsistent compliance with standards like CIS, NIST, or GDPR

Gaps in visibility across environments

Policies help fix that by ensuring each cluster stays aligned with your organization’s security, configuration, and operational standards.

🔧 What Is RHACM Policy Governance?

RHACM’s governance feature lets you define policies as Kubernetes custom resources. You can think of them as templates for enforcing:

Security rules (e.g., disallow privileged containers)

Configuration standards (e.g., specific labels or namespaces required)

Application health or deployment expectations

Cluster-wide network settings

Compliance checks and audits

And yes — all without jumping into every cluster individually.

📦 How It Works (No Code Required)

Here’s how the policy lifecycle looks using RHACM:

1. Define Policies Once

Use pre-built policy templates or create your own YAML files (or use the GUI) to define what you want to enforce — whether it’s disabling root containers or ensuring every pod has resource limits.

2. Group Clusters with Placement Rules

You can target clusters by labels or placement rules, meaning you can apply certain policies only to dev, staging, or prod environments.

3. Deploy with Confidence

In today’s modern software development world, container orchestration has become an essential practice. Imagine containers as tiny, self-contained boxes holding your application and all it needs to run; lightweight, portable, and ready to go on any system. However, managing a swarm of these containers can quickly turn into chaos. That's where container orchestration comes in to assist you. In this article, let’s explore the world of container orchestration. What Is Container Orchestration? Container orchestration refers to the automated management of containerized applications. It involves deploying, managing, scaling, and networking containers to ensure applications run smoothly and efficiently across various environments. As organizations adopt microservices architecture and move towards cloud-native applications, container orchestration becomes crucial in handling the complexity of deploying and maintaining numerous container instances. Key Functions of Container Orchestration Deployment: Automating the deployment of containers across multiple hosts. Scaling: Adjusting the number of running containers based on current load and demand. Load balancing: Distributing traffic across containers to ensure optimal performance. Networking: Managing the network configurations to allow containers to communicate with each other. Health monitoring: Continuously checking the status of containers and replacing or restarting failed ones. Configuration management: Keeping the container configurations consistent across different environments. Why Container Orchestration Is Important? Efficiency and Resource Optimization Container orchestration takes the guesswork out of resource allocation. By automating deployment and scaling, it makes sure your containers get exactly what they need, no more, no less. As a result, it keeps your hardware working efficiently and saves you money on wasted resources. Consistency and Reliability Orchestration tools ensure that containers are consistently configured and deployed, reducing the risk of errors and improving the reliability of applications. Simplified Management Managing a large number of containers manually is impractical. Orchestration tools simplify this process by providing a unified interface to control, monitor, and manage the entire lifecycle of containers. Leading Container Orchestration Tools Kubernetes Kubernetes is the most widely used container orchestration platform. Originally developed by Google and now maintained by the Cloud Native Computing Foundation (CNCF), Kubernetes offers a comprehensive set of features for deploying, scaling, and managing containerized applications. Docker Swarm Docker Swarm is Docker's native clustering and orchestration tool. It integrates seamlessly with Docker and is known for its simplicity and ease of use. Apache Mesos Apache Mesos is a distributed systems kernel that can manage resources across a cluster of machines. It supports various frameworks, including Kubernetes, for container orchestration. OpenShift OpenShift is an enterprise-grade Kubernetes distribution by Red Hat. It offers additional features for developers and IT operations teams to manage the application lifecycle. Best Practices for Container Orchestration Design for Scalability Design your applications to scale effortlessly. Imagine adding more containers as easily as stacking building blocks which means keeping your app components independent and relying on external storage for data sharing. Implement Robust Monitoring and Logging Keep a close eye on your containerized applications' health. Tools like Prometheus, Grafana, and the ELK Stack act like high-tech flashlights, illuminating performance and helping you identify any issues before they become monsters under the bed. Automate Deployment Pipelines Integrate continuous integration and continuous deployment (CI/CD) pipelines with your orchestration platform.

This ensures rapid and consistent deployment of code changes, freeing you up to focus on more strategic battles. Secure Your Containers Security is vital in container orchestration. Implement best practices such as using minimal base images, regularly updating images, running containers with the least privileges, and employing runtime security tools. Manage Configuration and Secrets Securely Use orchestration tools' built-in features for managing configuration and secrets. For example, Kubernetes ConfigMaps and Secrets allow you to decouple configuration artifacts from image content to keep your containerized applications portable. Regularly Update and Patch Your Orchestration Tools Stay current with updates and patches for your orchestration tools to benefit from the latest features and security fixes. Regular maintenance reduces the risk of vulnerabilities and improves system stability.
