Integrate with existing OpenVPN server

[underdark456]

Hello,
I wonder if it possible to integrate GUI with existing OpenVPN server?
Or can we somehow migrate?

You can add volumes to docker-compose, that points to your easyrsa directory and ccd and configure management service in your openvpn server config, passing it address to $OVPN_MGMT env. But if you have password on certificates, then you need to rewrite some code.

management service in your openvpn server config, passing it address to $OVPN_MGMT env

I have management 127.0.0.1 8989 in server.conf should i pass IP and port to $OVPN_MGMT ?

if you use ovpn-admin in docker, then change to management 0.0.0.0 8989, set env to OVPN_MGMT: "host.docker.internal:8989" and add this to ovpn-admin service in docker-compose file

extra_hosts:
  - "host.docker.internal:host-gateway"

Where do you specify the OVPN_MGMT? I tried adding the variable OVPN_MGMT: "host.docker.internal:8989" under the ovpn-admin service but then I get the following error:

Recreating openvpn-master_ovpn-admin_1 ... error

ERROR: for openvpn-master_ovpn-admin_1  Cannot create container for service ovpn-admin: conflicting options: custom host-to-IP mapping and the network mode

ERROR: for ovpn-admin  Cannot create container for service ovpn-admin: conflicting options: custom host-to-IP mapping and the network mode
ERROR: Encountered errors while bringing up the project.

I also changed the server.conf management address to management 0.0.0.0 8989

This is what my docker-compose.yml file looks like:

version: '3'

services:
  openvpn:
    build:
      context: .
      dockerfile: Dockerfile.openvpn
    image: openvpn:local
    command: /etc/openvpn/setup/configure.sh
    environment:
      OVPN_SERVER_NET: "10.9.0.0"
      OVPN_SERVER_MASK: "255.255.255.0"
      OVPN_PASSWD_AUTH: "true"
    cap_add:
      - NET_ADMIN
    ports:
      - 1234:1194 # for openvpn
      - 4567:8080 # for ovpn-admin because of network_mode
    volumes:
      - ./easyrsa_master:/etc/openvpn/easyrsa
      - ./ccd_master:/etc/openvpn/ccd
  ovpn-admin:
    build:
      context: .
    image: ovpn-admin:local
    command: /app/ovpn-admin
    environment:
      OVPN_DEBUG: "true"
      OVPN_VERBOSE: "true"
      OVPN_NETWORK: "10.9.0.0/24"
      OVPN_CCD: "true"
      OVPN_CCD_PATH: "/mnt/ccd"
      EASYRSA_PATH: "/mnt/easyrsa"
      OVPN_SERVER: "**PUBLIC-IP**:1234:tcp"
      OVPN_MGMT: "host.docker.internal:8989"
      OVPN_INDEX_PATH: "/mnt/easyrsa/pki/index.txt"
      OVPN_AUTH: "true"
      OVPN_AUTH_DB_PATH: "/mnt/easyrsa/pki/users.db"
      LOG_LEVEL: "debug"
    network_mode: service:openvpn
    volumes:
      - ./easyrsa_master:/mnt/easyrsa
      - ./ccd_master:/mnt/ccd
    extra_hosts:
      - "host.docker.internal:host-gateway"

Is there something else I could be missing?
