jetstackexperimental/cert-manager-controller repository overview

⁠cert-manager⁠

cert-manager is a Kubernetes addon to automate the management and issuance of TLS certificates from various issuing sources.

It will ensure certificates are valid and up to date periodically, and attempt to renew certificates at an appropriate 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.

⁠Current status

This project is not yet ready to be a component in a critical production stack, however is at a point where it offers comparable features to other projects in the space. If you have a non-critical piece of infrastructure, or are feeling brave, please do try cert-manager and report your experience here in the issue section.

NOTE: currently we provide no guarantees on our API stability. This means there may be breaking changes that will require changes to all Issuer/Certificate resources you have already created. We aim to provide a stable API after a 1.0 release.
