Managing TLS/SSL Certificates with Cert-Manager on OpenShift

Securing containerized applications with modern cryptographic standards is a fundamental requirement for any production deployment. This text-based course guides you through the concepts and practical steps needed to automate secure TLS/SSL certificates inside your cluster using OpenShift and the Cert-Manager Operator. You will start with foundational cloud-native security concepts before moving on to practical configurations. By completing this course, you will understand how to secure your application routes and ingress points, eliminate manual certificate renewal overhead, and maintain a robust security posture across your containerized environments. What you'll learn: - Understand the core concepts of public key infrastructure, certificate authorities, and TLS handshakes - Configure the Cert-Manager Operator on an OpenShift cluster using declarative manifests - Define custom resources like Issuers and ClusterIssuers to connect with public or private certificate authorities - Automate the provisioning and auto-renewal of TLS/SSL certificates for secure cluster routes - Implement modern zero-trust security practices by securing internal pod-to-pod communication - Troubleshoot common certificate validation, renewal, and configuration issues Starting with basic terminology and architecture, you will progress through configuring the operator, defining issuers, and securing active application endpoints. This course is designed for system administrators, DevOps engineers, and cloud-native beginners who want to build a solid foundation in modern cluster security. No prior certificate management experience is required, though basic familiarity with container concepts is helpful. Start securing your applications today.
