docker-gateway v5.3.0

docker-gateway

This project provides a gateway for use with Docker, allowing you to proxy multiple services from multiple domains.

Features

• Expose an http server
• Expose an https server using your custom certificates
• Works with websockets
• Manage routes via your swarm or compose labels

Local test

To test the examples, add this to your local /etc/hosts file:

127.0.0.1	one.test two.test something.three.test

Then run the example below, docker-compose.yml or docker-swarm.yml.

Syntax

Labels can be used to set some rules for the proxy. There are two available symbols:

-> is a transparent proxy to the url on right

=> is a 301 redirect proxy to the url on right
