Hello,

Unable to init server: Could not connect: Connection refused
(glabels-3:6): Gtk-WARNING **: 17:56:31.731: cannot open display:

if you are using OSX or Windows you'll need xquartz or vcxsrv respectively.

https://www.xquartz.org/
https://sourceforge.net/projects/vcxsrv/

For instance on windows, we need to use the IP address of the virtual network adapter that docker created (vEthernet):

And then in the PowerShell you define the DISPLAY variable:

set-variable -name DISPLAY -value 172.18.85.65:0.0
#localhost or 127.0.0.1 won't work.
You can define the display manually or check the log display server to confirm the current port.

And then you run it passing the variable as follows:
docker run -e DISPLAY=$DISPLAY 'mlgrm/glabels'
