I have a container which is only showing logs in the Docker Desktop application. I have 6 services in the compose file, and 5 of them show logs in my terminal as expected when launched with docker-compose -p my_app up. But one of them (api) doesn’t show the logs in the terminal, and I can only see them by using Docker Desktop.
This used to work, I don’t know what changed. How can I ensure that all the logging appears in the console? Software versions:
macOS: 12.3
Docker: 20.10.13, build a224086
Docker Compose: version v2.3.3
Here’s an excerpt of the compose file, showing the service that’s not working (api) and two others that ARE sending combined output to the console as expected.:
