A? Inspect the web server? Nah, that's for general container info, not error logs. B is the answer, and it's the one that won't make my head hurt trying to remember all those flags.

I personally think option C) docker run ---name WEB ---volume/dev/stdout:/var/log/nginx/error.log would be more effective in generating the errors.

D? Really? That's just for listing running containers, not getting the logs. Gotta go with B here, it's the classic go-to for this kind of issue.

C is interesting, but it seems a bit overkill just to view some error logs. I'd stick with the good old 'docker logs' command.

I agree with Elliott, using docker logs WEB would be the best way to see the error output.

Option B is the way to go, it's the easiest and most straightforward way to view the container's logs. No need to mess with volumes or fancy commands.
