cert-manager

cert-manager adds certificates and certificate issuers as resource types in Kubernetes clusters, and simplifies the process of obtaining, renewing and using those certificates. It can issue certificates from a variety of supported sources, including Let’s Encrypt, HashiCorp Vault, and Venafi as well as private PKI. It also takes care of the certificate validity, and attempt to renew certificates before expiry.
