It seems, that v0.16.0 does not write default password to docker container log.
Feel free to create new admin user after installation of this app.
After install App, do in terminal on Host:
sudo docker exec -it big-bear-write-freely /bin/bash
/usr/bin/writefreely --create-admin "bob:bobs_password" -c /etc/writefreely.ini
exit
Output of command creating new admin user:
