A Kubernetes controller that automatically manages Let's Encrypt TLS certificates, storing them as Kubernetes secrets via ACME dns-01 challenges. It uses ThirdParty Resources to declare certificates and supports multiple DNS providers through exec plugins.
Use cases
- automatically provision lets encrypt certificates in kubernetes
- manage tls secrets for kubernetes ingress load balancers
- renew acme certificates with dns-01 challenges
- secure web apps on kubernetes with free certificates
- learn how to write custom kubernetes controllers
When to choose
- you run an older Kubernetes cluster (1.3+) and want automated Let's Encrypt certs via dns-01
- you need TLS secrets for any TLS-terminating load balancer in Kubernetes
- you want a reference implementation for building custom Kubernetes controllers
When to avoid
- you need an actively maintained solution - the project hasn't released since 2018
- you need http-01 validation or modern cert-manager features
- you run a recent Kubernetes version where ThirdParty Resources are replaced by CRDs
