authentication error when connecting to db

[glw]

Hi I was just used your example to start up the db.

docker run -d -p 5432:5432
-e "PG_USER=user"
-e "PG_PASSWORD=mypass"
-e "DB_NAME=mydb"
--restart=unless-stopped
--volume=/docker_postgres/cityseer_postgresql11:/postgresql/11/main
cityseer/postgis:latest

And tried to make a basic connection with:
pgcli postgresql://user:mypass@localhost:5432/mydb

error:
FATAL: password authentication failed for user "user"

I would just like to work with the db locally. Am I doing something wrong?

Here is the output for docker log -f

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.

Success. You can now start the database server using:

    /usr/lib/postgresql/11/bin/pg_ctl -D /postgresql/11/main -l logfile start

There seems to be an issue when creating the new role.

It appears as thought when you supply your own user name and password it will not accept that. Because of the error listed above. Ive gone with the defaults and can now connect to the DB.
