                        --cap-drop=ALL \
                        --user=65534:65534 \
                        --read-only \
                        --mount type=bind,src=/tmp/languagetool/tmp,dst=/tmp \
                        -p 127.0.0.1:8010:8010 \

                        silviof/docker-languagetool:latest

Route information can be found at https://languagetool.org/http-api/swagger-ui/#/default, an easy route to test that it's running is /v2/languages.

ngram support

To support ngrams you need an additional volume or directory mounted to the /ngrams directory. For that add a -v to the docker run-command.

docker run ... -v /path/to/ngrams:/ngrams ...

Download English ngrams with the commands:

mkdir ngrams
wget https://languagetool.org/download/ngram-data/ngrams-en-20150817.zip
(cd ngrams && unzip ../ngrams-en-20150817.zip)
rm -f ngrams-en-20150817.zip

One can use them using web browser plugin "Local server (localhost)" setting by running:

docker run -d --name languagetool -p 127.0.0.1:8081:8010 -v `pwd`/ngrams:/ngrams:ro --restart=unless-stopped silviof/docker-languagetool
