cert-manager is a native Kubernetes certificate management controller. It can help with issuing certificates from a variety of sources, such as Let's Encrypt, HashiCorp Vault, Venafi, a simple signing keypair, or self signed.
It will ensure certificates are valid and up to date, and attempt to renew certificates at a configured time before expiry.
It is loosely based upon the work of kube-lego and has borrowed some wisdom from other similar projects e.g. kube-cert-manager.
This is the full technical documentation for the project, and should be used as a source of references when seeking help with the project.
