devpi-lockdown: tools to enable authentication for read access

This plugin adds some views to allow locking down read access to devpi.

Only tested with nginx so far.

Installation

devpi-lockdown needs to be installed alongside devpi-server.

You can install it with:

pip install devpi-lockdown

Usage

To lock down read access to devpi, you need a proxy in front of devpi which can use the provided views to limit access.

The views are:

/+authcheck

This returns 200 when the user is authenticated or 401 if not. It uses the regular devpi credential checks and an additional credential check using a cookie provided by devpi-lockdown to allow login with a browser.

/+login

A plain login form to allow access via browsers for use with devpi-web.

/+logout

Drops the authentication cookie.

For nginx the auth_request module is required and the configuration would something look like this:

server {
    ...

    # this redirects to the login view when not logged in
    error_page 401 = @error401;
    location @error401 {
        return 302 /+login;
    }

    # the location to check whether the provided infos authenticate the user
    location = /+authcheck {
        internal;

        proxy_pass_request_body off;
        proxy_set_header Content-Length "";
        proxy_set_header X-Original-URI $request_uri;
        proxy_set_header X-outside-url https://$host;
        proxy_pass http://localhost:3141;
    }

    # pass on /+login without authentication check to allow login
    location = /+login {
        proxy_set_header X-outside-url https://$host;
        proxy_pass http://localhost:3141;
    }

    # pass on /+api without authentication check for URL endpoint discovery
    location ~ /\+api$ {
        proxy_set_header X-outside-url https://$host;
        proxy_pass http://localhost:3141;
    }

    # use auth_request to lock down all the rest
    location / {
        auth_request /+authcheck;
        proxy_set_header X-outside-url https://$host;
        proxy_pass http://localhost:3141;
    }
}

If you use the example configuration from devpi-server then you have to add the auth_request check to the file and documentation parts as well.
