Proxy Auto-Configuration Manager

This application allows you to automatically generate PAC files based on the stored rules in the SQLite database.
It provides a simple CLI as well as a web interface to manage the rules.

Installation

Building from Source

As this package is using SQLite as a database, mattn/go-sqlite3 is used as a driver.
The "problem" with this package, is that it requires CGO to be enabled.
This means that you need to have the gcc installed on your system in order to be able to build the application from source.

The process of building the application from source is the same as for any other Go application.

Configuration

If you would like application to automatically discover configuration, you need to:

1. Create a directory /etc/pac.d - this is where the application will look for the configuration file
2. Create a file main.yaml inside the /etc/pac.d directory - this is the name of the configuration file that the application will look for

However, you can also use the following application arguments:

1. --config-path - path to where configuration file is located
2. --config - name of the configuration file

Main Configuration

Basic example configuration required to run application can be found in the examples/main.yaml.

There are 3 sections available for you to configure:

1. database - configuration for the SQLite database
2. server - configuration for the web server
3. pac - configuration for the PAC file

Database Configuration

• name - name of the database file
• path - path where the database file will be stored

PAC Configuration

• name - name of the generated PAC file
• path - path where the generated PAC file will be stored

Server Configuration

• host - host address on which the web server will be listening
• port - port on which the web server will be listening

Systemd Service

In order to be able to access web interface at all times without explicitly running pacm run, you can leverage the systemd service.

Provided example in examples/pacm.service will provide you with working service out of the box.

To install and enable service you need to do the following:

1. Copy the contents of the pacm.service to /lib/systemd/system/pacm.service
2. Run systemctl daemon-reload
3. Run systemctl enable pacm.service
4. Run systemctl start pacm.service

Assuming you have configured the service correctly, you should be able to access the web interface at http://0.0.0.0:8080.

Using a Reverse Proxy

You can find the example configuration for the Traefk reverse proxy in the examples/traefik-service.yaml

Assuming you've just installed the NGINX on the host machine with the default rules, only thing you need to do is to tell Traefik that static files will be served from the /files path.

Configuration provided in the example will allow you to access the web interface on the / path, and the generated PAC file on the /files/configuration.pac path.

Usage

Things worth noting:

1. Whenever you create or remove a proxy, PAC file will be regenerated
2. Whenever you create/update/remove a domain, PAC file will be regenerated
3. This logic applies to both CLI and Web interface.

CLI

The application provides a simple CLI that allows you to manage the rules and list of proxies.

To see the list of available commands, run pacm --help.

To see the list of available options for a specific command, run pacm <command> --help.

Most of the following commands provide you with interactive way of working with them.
Same functionality is present through the web interface.

• pacm run - runs the web server
• pacm version - prints the version of the application
• pacm proxy - lists commands for managing proxies
  • pacm proxy add - adds a new proxy
  • pacm proxy delete - removes a proxy
• pacm domain - lists commands for managing domains
  • pacm domain add - adds a new domain
  • pacm domain delete - removes a domain
  • pacm domain update - updates a domain
