Quick start (Docker)

Expand

First, run LibreTranslate container. It will take some time (~20 minutes) and resources (~1Gb memory, 10+Gb disk). When you see it's web interface at port 5000, move on to installing BookTr.

docker run --name ltr \
    -p 5000:5000 \
  libretranslate/libretranslate

docker run --name BookTr \
    -e "TZ=$YOURTIMEZONE" \                  # your TZ here
    -e "LTRPATH=http://$YOURADDRESS:5000" \  # LibreTranslate URL
    -v ~/.dockerdata/BookTr:/data/BookTr  \ 
    -p 8856:8856 \
