What Is the Red Hat Containers Certification?

The Red Hat Certified Specialist in Containers (EX180/EX188) is a performance-based certification that validates your ability to manage containers using Red Hat’s tools: Podman, Buildah, and Skopeo. Conducted in a Red Hat Enterprise Linux (RHEL) environment, the exam tests hands-on skills like creating containers, building images, configuring storage, and securing workloads. Unlike Kubernetes-focused certifications, EX180/EX188 focuses on container fundamentals, making it a perfect starting point for professionals aiming to work with platforms like OpenShift.

The certification is ideal for system administrators, developers, and DevOps engineers who want to master container management in enterprise settings. Its skills are directly applicable to OpenShift, Red Hat’s Kubernetes-based platform, enhancing your ability to deploy and manage containerized applications.

Understanding Red Hat OpenShift

Red Hat OpenShift is a Kubernetes-based platform that simplifies container orchestration, enabling enterprises to build, deploy, and scale applications efficiently. It provides a user-friendly interface, built-in CI/CD pipelines, and robust security features, making it a popular choice for cloud-native development.

Key features of OpenShift:

• Container Orchestration: Manages multiple containers across clusters using Kubernetes.
• Developer Tools: Offers tools like Source-to-Image (S2I) for building container images.
• Security: Integrates with SELinux and supports role-based access control (RBAC).
• Scalability: Enables automatic scaling of applications to meet demand.

The EX180/EX188 certification provides foundational container skills that align with OpenShift’s container management needs, preparing you for seamless deployments.

Red Hat Container Tools and Their Role

The EX180/EX188 certification focuses on three core tools that support OpenShift deployments:

• Podman: A daemonless container engine for running and managing containers, compatible with OpenShift’s pod-based architecture.
• Buildah: A tool for building and customizing container images, supporting OpenShift’s image-building processes like S2I.
• Skopeo: A utility for managing container images, enabling image transfers and inspections for OpenShift registries.

These tools, combined with RHEL and SELinux, provide a robust toolkit for managing containers in OpenShift environments, ensuring consistency and security.

How Certification Skills Support OpenShift

The skills gained from EX180/EX188 directly enhance your ability to work with OpenShift deployments:

• Container Management with Podman: Podman’s ability to create and manage containers mirrors OpenShift’s pod management, allowing you to test and deploy applications locally before scaling them.
• Image Building with Buildah: Buildah’s image-building capabilities align with OpenShift’s S2I process, enabling you to create custom images for deployment.
• Image Management with Skopeo: Skopeo’s ability to copy and inspect images supports OpenShift’s registry operations, ensuring trusted images are used.
• Storage and Networking: Configuring persistent storage and networking in the exam prepares you to manage OpenShift’s storage and network resources.
• Troubleshooting: Diagnosing container issues helps you resolve problems in OpenShift clusters, minimizing downtime.

These skills bridge the gap between standalone container management and OpenShift’s orchestrated environment, making you a valuable asset.

Enhancing OpenShift Security

Security is a critical aspect of OpenShift deployments, and the EX180/EX188 certification emphasizes practices that strengthen OpenShift’s security:

• Non-Root Containers: Running containers as non-root users, a key exam skill, aligns with OpenShift’s security policies to reduce privilege escalation risks.
• SELinux Integration: Using SELinux to enforce access controls ensures containers in OpenShift are isolated and secure.
• Image Security: Buildah and Skopeo enable you to create minimal images and verify their integrity, reducing vulnerabilities in OpenShift deployments.

These practices help meet enterprise compliance requirements and protect OpenShift clusters from threats.

Real-World OpenShift Deployment Scenarios

The EX180/EX188 skills are directly applicable to real-world OpenShift scenarios:

• CI/CD Pipelines: Use Buildah to create images and Podman to test them locally before deploying to OpenShift’s pipelines.
• Application Deployment: Configure storage and networking with Podman skills to deploy applications seamlessly in OpenShift.
• Image Management: Use Skopeo to manage images in OpenShift’s internal registry, ensuring consistency across clusters.
• Security Compliance: Apply SELinux and non-root configurations to meet regulatory standards in OpenShift environments.
• Troubleshooting: Resolve container issues in OpenShift clusters using diagnostic skills from the exam.

These applications make certified professionals essential for efficient and secure OpenShift deployments.

Preparing for the Certification with OpenShift in Mind

To maximize the certification’s value for OpenShift deployments, focus on these preparation steps:

• Set Up a Lab: Use RHEL or Fedora to practice with Podman, Buildah, and Skopeo.
• Explore OpenShift: Access Red Hat’s OpenShift Developer Sandbox to experiment with deployments.
• Master Podman: Practice running containers and configuring them to mimic OpenShift pods.
• Build Images with Buildah: Create images compatible with OpenShift’s S2I process.
• Use Skopeo: Practice managing images in registries to understand OpenShift’s registry workflows.
• Learn SELinux: Study SELinux policies to secure containers in OpenShift environments.
• Take Training: Enroll in Red Hat’s DO180 course for structured learning on container tools.

Plan for 2-3 months of study, combining hands-on practice with OpenShift-specific scenarios to build relevant skills.

Career Impact in OpenShift Environments
