WARNING: CouchDB is running in Admin Party mode.
This will allow anyone with access to the
CouchDB port to access your database. In
Docker's default configuration, this is
effectively any other container on the same
system.
Use "-e COUCHDB_USER=admin -e COUCHDB_PASSWORD=password"
to set it in "docker run".
