./openvpn-ui: cannot execute: required file not found

[vfdev-5]

Hi,

When trying to setup openvpn-server openvpn-ui together using docker-compose-openvpnui.yml, openvpn-ui service keeps restarting. Logs are showing:

Init. OVPN path: /etc/openvpn                                                                                                                    
Starting OpenVPN UI!                                                                                                                             
start.sh: line 33: ./openvpn-ui: cannot execute: required file not found   

What can be wrong in the configuration ? It would be good to get a better error message.

Another question, why we need priviledged: true option and mounting var docker volume for UI server? Thanks!

hi @vfdev-5, Thank s for reporting. Could you let me know which image you are using and what is the arch for your setup (docker inspect --format='{{json .Config.Labels}}' d3vilh/openvpn-ui:latest uname -a)?

The problem is openvpn-ui binary is not found when container attempt to start it.

We need to mount /var/docker to be able to restart openvpn server container via UI. Privileged is there just in case you have local openvpn-server with all the privileged permissions, for all other cases you could comment this line out.

Sure, I was using d3vilh/openvpn-ui:0.9.5.1 ({"maintainer":"Mr.Philipp <d3vilh@github.com>","version":"0.9.5.1"}) image on raspberry pi 2 (Linux rpi2 5.4.0-1069-raspi #79-Ubuntu SMP PREEMPT Thu Aug 18 18:18:46 UTC 2022 armv7l armv7l armv7l GNU/Linux). When I rebuild the image from source, it started working, hence the typo PR.

Thanks for explaining /var/docker and privileged, once I got into the UI I saw that it could restart openvpn server etc but before that just seeing docker-compose and UI part with high requirements like /var/docker and privileged were a bit surprising.

OK, I know what the problem, let me build image for ARM71. Ping you soon.

Hey @vfdev-5 Its ready.

Delete current container and its image (docker container rm openvpn-ui --force && docker image rm d3vilh/openvpn-ui --force) then run it from the docker-compose(docker-compose up -d) again and it will pull new ARMv7 image.

Here is starting logs from my test server:
