I bet the person who wrote this question is a secret comedian. 'docker-compose inspect WEB'? That's hilarious!

B) all the way! Who needs fancy volume mounts when you can just use the good old 'docker logs' command?

I would go with option B) docker logs WEB as well, it's a straightforward way to check for errors in the container.

Hmm, D) docker ps WEB -f doesn't seem right. That's just going to show me the running containers, not the logs.

A) docker-compose inspect WEB? Really? I'm not trying to inspect the container, I just want to see the errors!

I think option C) docker run ---name WEB ---volume/dev/stdout:/var/log/nginx/error.log could also work, as it redirects the error output to a log file.

I think C) is the way to go. Mapping the container's error log to the host's stdout is a neat trick!
