--with-docker unable to connect to local postgres when running integration tests

[agware]

Expected behaviour

Integration tests run with the --with-docker flag should connect to a postgres instance and run the tests

Actual behaviour

Failure to connect to database as root role

E       sqlalchemy.exc.OperationalError: (psycopg2.OperationalError) connection to server on socket "/var/run/postgresql/.s.PGSQL.5432" failed: FATAL:  role "root" does not exist
E       
E       (Background on this error at: https://sqlalche.me/e/14/e3q8)

/usr/local/lib/python3.10/dist-packages/psycopg2/__init__.py:122: OperationalError

Steps to reproduce the behaviour

1. Follow the setup guide for postgres
2. Run ./check-code.sh --with-docker integration_tests

Environment information

python == 3.11.4 <- in venv, 3.10.12 <- global
pytest == 7.4.0

Open Data Cube core, version 1.8.16.dev4+g24b046e7
Ubuntu 22.04.3 LTS

Additional Information

A temporary fix is mounting the datacube_information.conf file and changing the db_user to postgres, i.e.

In check_code.sh:

exec docker run $ti \
         -e SKIP_STYLE_CHECK="${SKIP_STYLE_CHECK:-no}" \
         -v $(pwd):/code \
         --mount type=bind,source="${HOME}"/.datacube_integration.conf,target=/root/.datacube_integration.conf,readonly \
         opendatacube/datacube-tests:latest \
         $0 $@

and in .datacube_integration.conf

db_username: postgres

Hi, are you sure you set up your postgres users correctly? Were you able to run sudo -u postgres createuser --superuser $USER successfully?

Hi Ariana, thank you for the reply.

Isn't the point of running check_code.sh with the --with-docker flag to bypass the local setup of postgres and instead use the provided container with a pre-configured option? So in this case, I don't believe that part of the set up doc is relevant. Happy to discuss further though.

Referring to your docs:
Alternatively one can use the opendatacube/datacube-tests docker image to run tests. This docker includes database server pre-configured for running integration tests. Add --with-docker command line option as a first argument to ./check-code.sh script.

./check-code.sh --with-docker integration_tests
