Automatic Certificate Issuance
Cert-Manager integrates with various certificate authorities (CAs) such as Let's Encrypt, HashiCorp Vault, and private CAs, allowing for automatic issuance of TLS certificates.
Automatic Renewal
One of the main features is the automatic renewal of certificates before they expire, avoiding failures in the secure communication process.
Security and Compliance
By automating the certificate management process, Cert-Manager contributes to a more robust security posture, helping to avoid the use of expired or incorrect certificates and ensuring that connections between microservices and with clients are always encrypted .
Reduction of Manual Errors
Automates the certificate management process, minimizing the risk of failures due to certificate expiration.
Ease of Configuration
With configuration via YAML and native Kubernetes integrations, installation and configuration of Cert-Manager is simplified. This also includes defining custom resources such as Certificate and Issuer, which control how certificates are requested and renewed.
Integration with Kubernetes
Cert-Manager uses Custom Resources Definitions (CRDs) and other native Kubernetes features, which makes it easy to install and configure in any container-based environment.
