To init the database, just execute:
$ sudo -u postgres psql -f postgres-docker/createdb.sql
By default the password is 'lamaurbain', if you want to change it, then execute:
$ sudo -u postgres psql postgres=# \password lamaurbain <type your password>
The final part is about creating a file named 'password' filled with the password you just gave. Then correct the file db_macaque_wrapper.ml with the address on which the database is located.
After that you can use Docker to build the project's image
$ docker build -t lamaserver
And then run it using this command
$ docker run -p 0.0.0.0:8080:8080 -t lamaserver
