DockerProxy is a small application to shield HTTP exporting Docker containers. The proxy supports SNI to shield the containers with HTTPs certificates. To discover the containers the Docker daemon needs to listen on a tcp port which should be shielded by a firewall to ensure the security of the Docker host.
Please pay attention: This project is no longer supported, will get no patches anymore and all issues will get closed silently!
There are some major bugs in this software which will not get fixed. You might want to get over to nginx-letsencrypt and use a nginx instead of this!
Currently Docker does not support container tagging so this proxy is using the environment variables to detect the “slug” and the port of a container. This can be fixed as soon as there is a tagging concept similar as the EC2 tagging in AWS.
ROUTER_SLUG: The slug used in the proxy configuration to identify the container
ROUTER_PORT: The public exported HTTP port the proxy can send its requests to
The configuration is written in YAML (or JSON) format and read every minute by the daemon:
domains: Dict of domain configurations the proxy is able to respond to
slug: The slug defined in the Docker container to determine which container should handle the request
force_ssl: The proxy does not forward request but return a redirect to SSL based connection
ssl(optional): SSL configuration for that domain
cert: x509 certificate file (Intermediate certificates belongs in this file too. Put them under your own certificate.)
key: The key for the cerficate without password protection
letsencrypt: Enable fetching the certificate from LetsEncrypt
authentication: Configure authentication for this domain
type: The authentication mechanism to use (Available:
config: Authentication specific configuration
generic: A generic suffix on which the proxy will forward to every configured container
listenHTTP: An address binding for HTTP traffic like
listenHTTPS: An address binding for HTTPs traffic like
docker: Docker host configuration
hosts: Dict of private to public host/ip associations (The Proxy will query the Docker daemon on the private host/ip and send traffic to the public host/ip)
port: Port to use for querying the Docker daemon
