* `USER_ENDPOINT` the URL to the Identity provider user endpoint, for gitlab this is "/api/v4/user". The "username" attribute of the returned JSON will used for authentication.
* `APP_KEY` random ASCII string, 32 characters in length. Used for cookie generation.
* `APP_LISTEN` port and ip to listen on, e.g. `:8000` or `127.0.0.1:3000`
* `VPN_DEV` which device is used by the network, either `tun` or `tap` (check server cfg)
* `VPN_HOST` Hostname or IP address of the server
* `VPN_PORT` Port of the VPN server
* `VPN_PROTO` Protocol of the VPN server, either `tcp` or `udp`
There are some files that need to be mounted inside the container:
* `/ca.crt` the certificate of the server PKI
* `/ca.key` the key of the server PKI, unencrypted
* `/ta.key` shared HMAC secret of server and client
* `/clients.json` the generated certificates for each client
There is an [`docker-compose.yml example`](docker-compose.yml.example) you can use as a base for your own docker-compose service.
