connect postgres error

[menghe999]

with the guide of article, I started the postgresql service in docker，but i can't connected the postgresql remote.

when i use command to connect the postgresql service，found error

[mengh@pa1 ~]$ psql -h pa3 -p 5432 -U postgresuser -d shipment_db
psql: error: connection to server at "pa3" (10.100.1.228), port 5432 failed: FATAL:  role "postgresuser" does not exist

but when i connect the the postgresql service in container，It's fine.

[mengh@pa3 ~]$ docker exec -it my_postgres_1 /bin/bash
root@5040544d402e:/# 
root@5040544d402e:/# psql -h localhost -p 5432 -U postgresuser -d shipment_db
psql (13.11 (Debian 13.11-1.pgdg110+1))
Type "help" for help.

shipment_db=# 
shipment_db=# \dt
Did not find any relations.
shipment_db=# 

So i don't know the reason for the error, have you met the error ？
