This repository provides a GoLang / Docker based, ACME-enabled reverse proxy. The goal was to provide a very simple, easy to use, reverse proxy that can be used to front web applications.
The reverse proxy is configured via environment variables. The following variables are supported:
| Variable | Description | Example |
|---|---|---|
PROXY_HOST |
The hostname(s) the proxy is listening on, comma-separated. | example.com,www.example.com |
PROXY_EMAIL |
The email address to register with letsencrypt. | [email protected] |
PROXY_TARGET |
The target URL to proxy requests to. | http://localhost:8080 |
The following example shows how to run the reverse proxy:
docker run --rm -p 8080:8080 -p 8443:8443 \
--env PROXY_HOST=76f1-45-14-97-5.ngrok-free.app \
--env [email protected] \
--env PROXY_TARGET=http://localhost:3000 \
-v "$(pwd)/certs":/home/autocert \
acme-proxyThe proxy will listen on port 8080 for HTTP requests and on port 8443 for HTTPS requests.
Mounting a (persistent) volume to /home/autocert is recommended to persist the certificates. Let's Encrypt restricts
the number of certificates that can be issued per week. Persisting the certificates allows the proxy to reuse them
across restarts.
