ARPOC

A simple reverse proxy that adds OpenID Connect Authentication and lets you write access rules for services you want to protect.

Fast tutorial

You will need:

• A domain name <domain>
• A tls keypair (<fullchain>, <privkey>)
• A server with python (3.7 or newer) <python3>

Install

• Download the repository and run <python3> setup.py install, or install via pip: pip install arpoc
• If successful you should now have the arpoc command.
• Make yourself familiar with the basic interface with arpoc --help.
• Create a configuration file arpoc --print-sample-config
• Save the configuration file (preferable under /etc/arpoc/config.yml)
• Create a default access control hierarchy using arpoc --print-sample-config
• Save the access control hierarchy in a json file (defaultdir: /etc/arpoc/acl/)

Edit the sample configuration

Fill in the right values for <keyfile>, <certfile>, <domainname>, <redirect> urls (path the openid connect providers will redirect the user to, with a leading slash) and the contacts field (at least on valid mail adress).

Add an openid connect provider

You need the configuration url (should end with .well-known/openid/configuration, cut this part of, it is added automatically). You also need either:

• A configuration token
• A registration url and a registration token
• Client ID and Client Secret

Configuration URL and Token:

Choose a key which arpoc uses internally for the provider.

Add both parameters to the config.yml under openid_providers -> <key> -> configuration_url openid_providers -> <key> -> configuration_token

Registration URL and registration token:

If you already registered your client and have a registration token add the configuration url, the registration url and the registration token under to the config.yml file under openid_providers -> <key> using the configuration_url, registration_url and registration_token.

Client ID and Client Secret

Add the configuration url to the config.yml. Call arpoc --add-provider <key> --client-id <client_id> --client-secret <client-secret>

Add a service you want to protect.

You need the origin url, the proxy url and the key of an access control policy set (the key of an ac entity in the json file with type policy set).

Choose a key which arpoc will internally use for the service. Add the origin url and the proxy url (the path under which the service will be available with a leading slash) using the origin_URL and proxy_url keys under services -> <service key> -> to the config.yml

Now you should be able to access the service.
