Let's Encrypt Nginx-proxy Companion
A Docker container that automatically generates and renews Let's Encrypt SSL certificates for nginx-proxy.
What is Let's Encrypt Nginx-proxy Companion?
acme-companion is a Docker container that automatically manages SSL certificates for applications proxied through nginx-proxy. It handles the entire certificate lifecycle—creation, renewal, and deployment—using the ACME protocol (primarily with Let's Encrypt). This solves the problem of manually configuring and maintaining SSL certificates in Docker-based environments.
DevOps engineers, system administrators, and developers who use Docker and nginx-proxy to host multiple web applications and need automated SSL certificate management.
Developers choose acme-companion because it provides zero-configuration SSL automation specifically designed for nginx-proxy environments, eliminating manual certificate renewal tasks while maintaining compatibility with all Docker versions and supporting both HTTP-01 and DNS-01 challenges.
