Current Issues

1. Postgres DB keeps logging - role 'root' does not exist. Still figuring out how to take care of this. The db works regardless though.
2. Shipping logs using vector still needs a bit of work.
3. Postgres has a new error. Though at the LOG severity - invalid length of statup packet. The internet says it has to do with connections to the DB but only the django service id currently connected.
4. Mongodb express keeps trying to connect to mongo before mongo is fully operational even with the depends_on attribute
5. Graphana is a pain.
