     > The live-mounted code is now under `/code`. Note that the `DEBUG=true` environment variable is still set. If you want to test things on production, run `export DEBUG=false`. Running `python runner.py` will now run the newly written code but, with the production database and storage.
 
 * For `check` mode, some env-variables are also changed and you still require interactivity. You don't need the geckodriver service however. The simplest way is to run
 
-    `docker compose --env-file env/check run news_fetch`
+    `docker compose --env-file env/check run --no-deps --rm news_fetch`
