About cert-manager
cert-manager is an open source certificate management controller designed specifically for Kubernetes and OpenShift environments. It automates the issuance, renewal, and management of X.509 certificates, ensuring secure TLS communication for both ingress traffic and internal workloads. By integrating with a variety of public and private certificate authorities, cert-manager simplifies the complex process of certificate lifecycle management within cloud-native infrastructures.
Targeted at enterprises running containerized applications, cert-manager enhances security by enabling automated certificate provisioning and renewal, reducing manual overhead and minimizing the risk of certificate expiration. Its extensible design supports secure pod-to-pod communication through mutual TLS using private PKI issuers, making it suitable for service mesh security and other internal communication scenarios. Backed by the CNCF and major cloud providers, cert-manager offers a robust solution for organizations seeking to maintain compliance and security in dynamic Kubernetes environments.
