Dockerized VPN Proxy

Magical HTTP and SOCKS4/SOCKS5 proxy behind VPN (without host being on VPN)

Other joestldr used containers under this docker compose project:

• dockerized-openvpn-client
  • https://hub.docker.com/r/joestldr/openvpn-client
  • https://github.com/joestldr/dockerized-openvpn-client
• dockerized-http-proxy
  • https://hub.docker.com/r/joestldr/http-proxy
  • https://github.com/joestldr/dockerized-http-proxy
• dockerized-srelay
  • https://hub.docker.com/r/joestldr/srelay
  • https://github.com/joestldr/dockerized-srelay
• dockerized-toolbox

TLDR; Quickstart... But not so quick...

Assuming your VPN server requires username/password... This is straightforward... If not... I believe in you!~ You will figure it out ^^,

Step #1: Checkout .git and make tmp and config/openvpn subfolder

git clone git@github.com:joestldr/dockerized-vpn-proxy.git; \
cd dockerized-vpn-proxy; \
mkdir -p ./tmp ./config/openvpn

Step #2: .env

cat <<\EOF > ./config/.env
DNS_PRIMARY=9.9.9.9
DNS_SECONDARY=149.112.112.112
CHECK_IP_URL=https://checkip.amazonaws.com
CHECK_IP_PATH=/tmp/get-local-public-ip
CHECK_IP_FILE=/tmp/get-local-public-ip/LOCAL_PUBLIC_IP
EOF

Note: These sample values can work as-is... READ docker-compose.yaml to understand where/why these values are used.

Note: joestldr is a big fan of QUAD9 DNS (9.9.9.9, 149.112.112.112): https://www.quad9.net/

Step #3 config/openvpn

Add your VPN server configuration file as ./config/openvpn/client.ovpn and username/password as ./config/openvpn/client.pass:

• ./config/openvpn/client.ovpn

  client
  dev tun
  proto udp
  remote sg-sng.prod.surfshark.com 1194
  # ...
  # etc. etc. etc.

  Note: joestldr is a big fan of Surfshark: https://surfshark.com/
• ./config/openvpn/client.pass

  FIRST_LINE_IS_USERNAME
  SECOND_LINE_IS_PASSWORD

Step #4 Review

tree .
.
├── compose.sh
├── config
│   └── openvpn
│       ├── client.ovpn
│       └── client.pass
├── docker-compose.yaml
├── README.md
└── tmp

Step #5 CONNECT!~

./compose.sh start

Note: This will launch detached docker compose up --detach, and will just immediately docker compose logs -f after.

Test!~

# your actual own public IP
curl --noproxy checkip.amazonaws.com https://checkip.amazonaws.com

# test http-proxy
curl --proxy http://127.0.0.1:3128 https://checkip.amazonaws.com

# test socks-proxy
curl --proxy socks://127.0.0.1:1080 https://checkip.amazonaws.com
curl --proxy socks4://127.0.0.1:1080 https://checkip.amazonaws.com
curl --proxy socks5://127.0.0.1:1080 https://checkip.amazonaws.com
