Ergo Proxy - The reverse proxy agent for local domain management.

The management of multiple apps running over different ports made easy through custom local domains.

See more on examples

Ergo's goal is to be a simple reverse proxy that follows the Unix philosophy of doing only one thing and doing it well. Simplicity means no magic involved. Just a flexible reverse proxy which extends the well-known /etc/hosts declaration.

Feedback

This project is constantly undergoing development, however, it's ready to use. Feel free to provide feedback as well as open issues. All suggestions and contributions are welcome. :)

Dealing with multiple apps locally, and having to remember each port representing each microservice is frustrating. I wanted a simple way to assign each service a proper local domain. Ergos solves this problem.

brew tap cristianoliveira/tap
brew install ergo

curl -s https://raw.githubusercontent.com/cristianoliveira/ergo/master/install.sh | sh

From powershell run:

Invoke-WebRequest https://raw.githubusercontent.com/cristianoliveira/ergo/master/install.ps1 -out ./install.ps1; ./install.ps1

You can also find the Windows executables in release.

Disclaimer: I use Unix-based systems on a daily basis, so I am not able to test each build alone. :(

go install github.com/cristianoliveira/ergo

Make sure you have $GOPATH/bin in your path: export PATH=$PATH:$GOPATH/bin

Ergo looks for a .ergo file inside the current directory. It must contain the names and URL of the services following the same format as /etc/hosts (domain+space+url). The main difference is it also considers the specified port.

You need to set the http://127.0.0.1:2000/proxy.pac configuration on your system network config.

Ergo comes with a setup command that can configure it for you. The current systems supported are:

• osx
• linux-gnome
• windows

ergo setup <operation-system>

In case of errors / it doesn't work, please look at the detailed config session below.

echo "ergoproxy http://localhost:3000" > .ergo
ergo run

Now you should be able to access: http://ergoproxy.dev. Ergo redirects anything ending with .dev to the configured url.

Simple, right? No magic involved.

Do you want to add more services? It's easy, just add more lines in .ergo:

echo "otherservice http://localhost:5000" >> .ergo
ergo list
ergo run

Restart the server and access: http://otherservice.dev

In order to use Ergo domains you need to set it as a proxy. Set the http://127.0.0.1:2000/proxy.pac on:

Network Preferences > Advanced > Proxies > Automatic Proxy Configuration

Settings > Network and Internet > Proxy > Use setup script

On Ubuntu

System Settings > Network > Network Proxy > Automatic

For other distributions, check your network manager and look for proxy configuration. Use browser configuration as an alternative.

Browsers can be configured to use a specific proxy. Use this method as an alternative to system-wide configuration.

Exit Chrome and start it using the following option:

# Linux
$ google-chrome --proxy-pac-url=http://localhost:2000/proxy.pac

# OS X
$ open -a "Google Chrome" --args --proxy-pac-url=http://localhost:2000/proxy.pac

As an alternative you can see the scripts inside /resources for running an ephemeral setup. Those scripts set the proxy only while ergo is running.
