This is a NordVPN client docker container using openvpn that use the recommended NordVPN servers, and opens a SOCKS5 (dante server) and http proxy (tinyproxy).
VPN servers selection is performed through nordnvpn API.(country, technology, protocol)
Added docker image version for raspberry.
Whenever the connection is lost the unbound, tinyproxy and sock daemons are killed, disconnecting all active connections (tunnel down event).
This image is largely based on jeroenslot/nordvpn-proxy with dante free socks server added.
you can then expose port 1080 from the container to access the VPN connection via the SOCKS5 proxy.
To sum up, this container:
- Opens the best connection to NordVPN using openvpn and the conf downloaded using NordVpn API according to your criteria.
- Starts a HTTP proxy that route
eth0:8888toeth0:1080(socks server) with tinyproxy - Starts a SOCKS5 proxy that routes
eth0:1080totun0/nordlynxwith dante-server. - Starts unbound as dnssec querying specified DNS.
The main advantage is that you get the best recommendation for each selection.
Script for OpenVpn config download is base on the one developped for haugene 's docker transmission openvpn https://haugene.github.io/docker-transmission-openvpn/provider-specific/
The container is expecting three parameters to select the vpn server:
- NORDVPN_COUNTRY define the exit country.
- NORDVPN_PROTOCOL although many protocols are possible, only tcp or udp are available.
- NORDVPN_CATEGORY although many categories are possible, p2p seems more adapted.
NOTE: This container works best using the
p2ptechnology.NOTE: At the moment, this container has no kill switch... meaning that when the VPN connection is down, the connection will be rerouted through your provider. although, on tunnel down event, the socks server is stopped preventing to relay unprotected requests, and defaults route through eth0 (not vpn) are deleted.
NOTE: as of 22/03/28, NORDVPN_LOGIN and NORDVPN_PASS secrets file are replaced with a single file, NORDVPN_CREDS, having login at first line and password as the second line.
- DNS to uses external DNS, if none given: "1.1.1.1@853#cloudflare-dns.com 1.0.0.1@853#cloudflare-dns.com"
- NORDVPN_USER=email or service user
- NORDVPN_PASS=pass or service pass
- EXIT_WHEN_IP_NOTEXPECTED=(0|1) # stop container when detected network is not as expected (based on /24 networks)
- NORDVPN_SERVER=<#>.nordvpn.com: eg: nl568.nordvpn.com, get configuration based on server's fqdn, bypassing all api's recommendations. Connection may fail when the server is offline or overloaded. has precedence over NORDVPN_COUNTRY and NORDVPN_CATEGORY.
- NORDVPN_TESTS=[1-4], simple tests to test basic api filtering functions.
- WRITE_OVPN_STATUS=(0|1): write openvpn status (CONNECTED/NOTCONNECTED) to /var/tmp/ovpn_status. you may mount the file to get the openvpn status outside the container.
- WAITSEC=30, default value, time to wait between two vpn login.
- Just copy/paste the grey text block starting with version 3.8. to a file named docker-compose.yml
- Set values for NORDVPN_TECHNOLOGY, NORDVPN_PROTOCOL, NORDVPN_COUNTRY
- adapt if needed LOCAL_NETWORK, TZ
- create file nordvpn_creds containing your login in the first line and your password in the second line.
nordvpn_creds:
thisismyusername
thisismypassword
Nordvpn openvpn credentials are to be found following that procedure:
-
Go to NordVPN website and log in
-
Under accounts - Services - click NordVPN
-
Click - Set up NordVPN manually - at the bottom right of the page.
-
You will receive a verification code in your email that you use for NordVPN services. Type the code in the popup window the preceded the email check.
-
Copy the credentials using the “Copy” buttons on the right for your new encrypted user name and password and paste them in nordvpn_creds
-
start the container: docker compose up -d
once the container is started, you will see in the logs these two lines, indicating that both socks and http proxies are up.

script checks for:
- proper dnssec resolution
- openvpn service being up
- openvpn being connected
- warns if openvpn remote ip seems not coherent
if any of these fail, services are restarted.
dockerfile healtcheck:
- use NORDVPN api to validate protection
if test $( curl -m 10 -s https://api.nordvpn.com/vpn/check/full | jq -r '.["status"]' ) = "Protected" ; then exit 0; else exit 1; fi
When vpn interface (tun) is up, default route through unprotected interface (eth0) is removed.
To ensure that little or no traffic is forwarded unprotected, services are stopped on any of these events:
- when the api returns that the status is not protected, the container stops.(every 5min)
- when openvpn returns a status NOTCONNECTED, all services are stopped, openvpn is restarted. when ok, dante and tinyproxy are started.(checked every 5 minutes)
- when openvpn service is stopped, the down phase (runit feature) stops all other services.
- when the tun interface is disconnected, openvpn fires the down.sh script, stopping all services.
Another image is available using nordvpn's client. Openvpn and wireguard (nordlynx) protocols are available. better speed may be achieved with wireguard.
