As I use docker,
I tried to input
docker run --rm -ti tryton/tryton trytond-console -d tryton_database

There is this error returned :

connection to “tryton_database” failed

You seem to not have link your instance with the postgres database with --link tryton-postgres:postgres like in https://hub.docker.com/r/tryton/tryton

Hi,
Thanks for your fast answer
I modified the command as so :

docker run --network tryton_network --link tryton_postgres:postgres -e DB_PASSWORD=XXXXXXX --rm -ti tryton/tryton trytond-console -d tryton_database

Now Powershell displays this :

/usr/lib/python3/dist-packages/passlib/utils/init.py:854: DeprecationWarning: ‘crypt’ is deprecated and slated for removal in Python 3.13
from crypt import crypt as _crypt
:1049: ImportWarning: PluginImportFixer.find_spec() not found; falling back to find_module()
/usr/lib/python3/dist-packages/zeep/utils.py:1: DeprecationWarning: ‘cgi’ is deprecated and slated for removal in Python 3.13
import cgi
/usr/local/lib/python3.11/dist-packages/braintree/dispute.py:83: DeprecationWarning: Use ProtectionLevel enum instead

warnings.warn(“Use protection_level parameter instead”, DeprecationWarning)
:1049: ImportWarning: PluginImportFixer.find_spec() not found; falling back to find_module()

Then the cursor blinks and I can type but it doesn’t seem to react.

Am I doing this right please ?
