Automatically provision and manage TLS certificates in Kubernetes.
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 supports issuing certificates from a variety of sources, including Let's Encrypt (ACME), HashiCorp Vault, and Venafi TPP / TLS Protect Cloud, as well as local in-cluster issuance.
cert-manager also ensures certificates remain valid and up to date, attempting to renew certificates at an appropriate time before expiry to reduce the risk of outages and remove toil.
