C looks complicated, why not just use B?

Wait, can you really use docker logs for that? Seems too simple.

I remember that `docker ps` shows running containers, but I don't think it would help with error output. It seems like `docker logs` is the best choice here.

I’m a bit confused about the options. I feel like `docker-compose inspect` just gives details about the configuration, not the logs.

I practiced a similar question where we had to check logs for a container, and I think `docker logs WEB` was the right answer there too.

I think I remember that `docker logs` is used to view the output from a container, but I'm not entirely sure if it shows errors specifically.

I think forming an alliance with a local supplier is the way to go. It would give Mitch access to more resources and potentially better pricing, which could really help grow the business. The other options seem a bit risky or complex.

I think we learned that when you stick with the same instance type, some configurations remain static. Maybe it's about the memory size?

This seems pretty straightforward. I think the answer is D - starting a timer when the request is made and stopping it when the result is received.

I once tried to use option A to debug a container, and it just made me feel like I was playing a game of 'Where's Waldo?' with the error messages. Stick to the classics, people!

Option B seems like the logical choice to view the container's logs. Why would you need to inspect the container when you can just view the logs directly?
