Docker img error

[santime27]

Hi everyone. I have an issue when I try to launch a optuna-dashboard from docker image. I have a postgres sql database run in a Docker container locally, but when I launch a optuna-dashboard using the following docker command from git hub "$ docker run -it --rm -p 8080:8080 ghcr.io/optuna/optuna-dashboard postgresql+psycopg2://root:root@postgres:5432/optunadb" with my own information about username and password. I get the issue "could not translate host name "postgres" to address: Name or service not known". obviously I change the hostname between localhost,127.0.0.0 and my docker container postgress name. Also I try with mysql but I have the same issue. also I have pgadmin to try connection with postgres sql database and the connection is success.
