Configurable DB_NAME

[singatias]

Hello,

Why is the database name hardcoded? Even if you change it in the odoo.conf, the Docker container won't be compatible with a PostgreSQL database that doesn't have a database named 'postgres'. Multiple people have reported this issue and created PRs to address it, but none of them have been taken seriously. I'm currently creating a Helm chart for Odoo and have to jump through hoops to get it set up.

#459 #426

Obviously these PRs were neglected for so long but it would be nice if the Odoo team merge a solution once and for all to this issue.

docker/18.0/wait-for-psql.py

Line 21 in 6b73961

conn = psycopg2.connect(user=args.db_user, host=args.db_host, port=args.db_port, password=args.db_password, dbname='postgres')

	value=$(grep -E "^\s*\b${param}\b\s*=" "$ODOO_RC" |cut -d " " -f3|sed 's/["\n\r]//g')
	fi;
	DB_ARGS+=("--${param}")
	DB_ARGS+=("${value}")
	}
	check_config "db_host" "$HOST"
	check_config "db_port" "$PORT"
	check_config "db_user" "$USER"
	check_config "db_password" "$PASSWORD"
