Translation file Xibo for Docker

Where can I put the translation file .po in my Xibo for Docker installation?

A .po file will not work and needs to be compiled in to a .mo file which needs to go inside the locale folder inside the container. You could do this by either copying there directly when the container is running, or you could map it by adding a line to the volumes section of the docker-compose.yml file, or whichever yml file you are using.

Thank you
