About Cert-Manager
cert-manager is an open-source Kubernetes add-on that automatically provisions, issues, and renews TLS certificates from sources like Let's Encrypt, HashiCorp Vault, and private CAs. It manages certificates as native Kubernetes resources, handling ACME challenges and rotation without manual intervention. It is a de facto standard for certificate automation in cloud-native platform and DevOps teams.
