Connect to the database yourself
Open psql in the container of the datastore, or connect from your machine through an SSH tunnel.
From the server
Open psql in the container of the datastore.
docker exec -it ferry-ds-notes-db psql -U notes_db notes_dbThe name of the container is <prefix>-ds-<name>. With the default prefix, it is ferry-ds-notes-db.
From your machine
Use the external URL that ferry db show notes-db prints. Its port is open only on 127.0.0.1 of the server. Thus make an SSH tunnel first.
ssh -L 62975:127.0.0.1:62975 you@your-server
psql 'postgresql://notes_db:…@127.0.0.1:62975/notes_db'
