  $ docker run -t -d \
  -p 9980:9980 \
  -e "username=admin" \
  -e "password=admin" \
  --name collabora \
  --cap-add MKNOD \
  collabora/code
  

• Update Collabora Server docker and modify SSL settings

  $ docker exec -it collabora /bin/bash -c "apt-get -y update && apt-get -y install xmlstarlet && xmlstarlet ed --inplace -u \"/config/ssl/enable\" -v false /etc/loolwsd/loolwsd.xml && xmlstarlet ed --inplace -u \"/config/ssl/termination\" -v false /etc/loolwsd/loolwsd.xml"
  

• Restart updated docker, wait 30 seconds and retrieve IP of the server

  $ docker restart collabora
