Hello, I have a problem with environment variables. All are not taken into account I am working on a deployment of GenieACS in a Kubernetes cluster. And Kubernetes doesn’t have IPv6 support. And since version 1.2.6 commit “Default to dual stack interface binding” IPv6 is enabled by default and is mandatory. If there is no IPv6 the application crashes with the message exceptionName=“Error” exceptionMessage=“bind EAFNOSUPPORT:::3000” So I tested by adding in genieacs.env UI\_INTERFACE=“0.0.0.0” to force IPv4 only. But it does not change anything. For double check, I did another installation of GenieACS on an Ubuntu 20 VM without ipv4, following the documentation As expected by default the application does not launch because of non IPv6. I add UI\_INTERFACE=“0.0.0.0” in genieacs.env and ditto it crashes. For test, I made a build by modifying lib/config.ts UI\_INTERFACE: { type: “string”, default: “0.0.0.0” }, The UI launches fine I think this problem is not for all variables. for example GENIEACS\_MONGODB\_CONNECTION\_URL seems to be taken into account. ## Here is my configuration and logs ```auto root@ubunutu-vm:~# cat /opt/genieacs/genieacs.env GENIEACS_CWMP_ACCESS_LOG_FILE=/var/log/genieacs/genieacs-cwmp-access.log GENIEACS_NBI_ACCESS_LOG_FILE=/var/log/genieacs/genieacs-nbi-access.log GENIEACS_FS_ACCESS_LOG_FILE=/var/log/genieacs/genieacs-fs-access.log GENIEACS_UI_ACCESS_LOG_FILE=/var/log/genieacs/genieacs-ui-access.log GENIEACS_DEBUG_FILE=/var/log/genieacs/genieacs-debug.yaml NODE_OPTIONS=--enable-source-maps GENIEACS_EXT_DIR=/opt/genieacs/ext GENIEACS_UI_JWT_SECRET=secret UI_INTERFACE="0.0.0.0" ``` * * * ```auto root@ubunutu-vm:~# ls -alh /opt/genieacs/ total 16K drwxr-xr-x 3 genieacs genieacs 4.0K Mar 26 19:14 . drwxr-xr-x 4 root root 4.0K Mar 26 17:21 .. drwxr-xr-x 2 genieacs genieacs 4.0K Mar 26 17:21 ext -rw------- 1 genieacs genieacs 462 Mar 26 17:31 genieacs.env ``` * * * ```auto /etc/systemd/system/.#genieacs-ui.servicea4ab2afb45c1caec [Unit] Description=GenieACS UI After=network.target [Service] User=genieacs EnvironmentFile=/opt/genieacs/genieacs.env ExecStart=/usr/bin/genieacs-ui [Install] WantedBy=default.target ``` * * * ```auto root@ubunutu-vm:~# systemctl status genieacs-ui ● genieacs-ui.service - GenieACS UI Loaded: loaded (/etc/systemd/system/genieacs-ui.service; disabled; vendor preset: enabled) Active: failed (Result: exit-code) since Sat 2022-03-26 17:34:46 UTC; 1h 40min ago Process: 9616 ExecStart=/usr/bin/genieacs-ui (code=exited, status=1/FAILURE) Main PID: 9616 (code=exited, status=1/FAILURE) Mar 26 17:34:27 ubunutu-vm genieacs-ui[9616]: 2022-03-26T17:34:27.823Z [ERROR] Worker died; pid=10615 exitCode=0 Mar 26 17:34:29 ubunutu-vm genieacs-ui[10630]: 2022-03-26T17:34:29.774Z [ERROR] Uncaught exception; pid=10630 exceptionName="Error" exceptionMessage="bind EAFNOSUPPORT :::3000" exceptionStack="Error: bind EAFNOSUPPORT :::3000\n at __nod> Mar 26 17:34:29 ubunutu-vm genieacs-ui[9616]: 2022-03-26T17:34:29.845Z [ERROR] Worker died; pid=10630 exitCode=0 Mar 26 17:34:31 ubunutu-vm genieacs-ui[10645]: 2022-03-26T17:34:31.754Z [ERROR] Uncaught exception; pid=10645 exceptionName="Error" exceptionMessage="bind EAFNOSUPPORT :::3000" exceptionStack="Error: bind EAFNOSUPPORT :::3000\n at __nod> Mar 26 17:34:31 ubunutu-vm genieacs-ui[9616]: 2022-03-26T17:34:31.839Z [ERROR] Worker died; pid=10645 exitCode=0 Mar 26 17:34:33 ubunutu-vm genieacs-ui[10660]: 2022-03-26T17:34:33.769Z [ERROR] Uncaught exception; pid=10660 exceptionName="Error" exceptionMessage="bind EAFNOSUPPORT :::3000" exceptionStack="Error: bind EAFNOSUPPORT :::3000\n at __nod> Mar 26 17:34:33 ubunutu-vm genieacs-ui[9616]: 2022-03-26T17:34:33.840Z [ERROR] Worker died; pid=10660 exitCode=0 Mar 26 17:34:33 ubunutu-vm genieacs-ui[9616]: 2022-03-26T17:34:33.840Z [ERROR] Too many crashes, exiting; pid=9616 Mar 26 17:34:46 ubunutu-vm systemd[1]: genieacs-ui.service: Main process exited, code=exited, status=1/FAILURE Mar 26 17:34:46 ubunutu-vm systemd[1]: genieacs-ui.service: Failed with result 'exit-code'. ``` ---

You have to use the prefix GENIEACS\_ otherwise it will not work. So it would be GENIEACS\_UI\_INTERFACE ---
