Simple web UI to manage OpenVPN users, their certificates & routes in Linux. While backend is written in Go, frontend is based on Vue.js.

Originally created in Flant for internal needs & used for years, then updated to be more modern and publicly released in March'21. Your contributions are welcome!

DISCLAIMER! This project was created for experienced users (system administrators) and private (e.g., protected by network policies) environments only. Thus, it is not implemented with security in mind (e.g., it doesn't strictly check all parameters passed by users, etc.). It also relies heavily on files and fails if required files aren't available.


  • Adding, deleting OpenVPN users (generating certificates for them);
  • Revoking/restoring/rotating users certificates;
  • Generating ready-to-user config files;
  • Providing metrics for Prometheus, including certificates expiration date, number of (connected/total) users, information about connected users;
  • (optionally) Specifying CCD (client-config-dir) for each user;
  • (optionally) Operating in a master/slave mode (syncing certs & CCD with other server);
  • (optionally) Specifying/changing password for additional authorization in OpenVPN;
  • (optionally) Specifying the Kubernetes LoadBalancer if it's used in front of the OpenVPN server (to get an automatically defined remote in the client.conf.tpl template).
  • (optionally) Storing certificates and other files in Kubernetes Secrets (Attention, this feature is experimental!).


Managing users in ovpn-admin: ovpn-admin UI

An example of dashboard made using ovpn-admin metrics: ovpn-admin metrics


1. Docker

There is a ready-to-use docker-compose.yaml, so you can just change/add values you need and start it with start.sh.

Requirements: You need Docker and docker-compose installed.

Commands to execute:

git clone https://github.com/flant/ovpn-admin.git
cd ovpn-admin


Ready docker images available on Docker Hub . Tags are simple: $VERSION or latest for ovpn-admin and openvpn-$VERSION or openvpn-latest for openvpn-server

2. Building from source

Requirements. You need Linux with the following components installed:

Commands to execute:

git clone https://github.com/flant/ovpn-admin.git
cd ovpn-admin

(Please don't forget to configure all needed params in advance.)

3. Prebuilt binary

You can also download and use prebuilt binaries from the releases page — just choose a relevant tar.gz file.


  • this tool uses external calls for bash, coreutils and easy-rsa, thus Linux systems only are supported at the moment.
  • to enable additional password authentication provide --auth and --auth.db="/etc/easyrsa/pki/users.db" flags and install openvpn-user. This tool should be available in your $PATH and its binary should be executable (+x).
  • master-replica synchronization does not work with --storage.backend=kubernetes.secrets - WIP
  • additional password authentication does not work with --storage.backend=kubernetes.secrets - WIP
  • if you use --ccd and --ccd.path="/etc/openvpn/ccd" abd plan to use static address setup for users do not forget to provide --ovpn.network="" with valid openvpn-server network
  • tested only with Openvpn-server versions 2.4 and 2.5 with only tls-auth mode
  • not tested with EasyRsa version > 3.0.8
  • status of users connections update every 28 second(no need to ask why =))
