Wait, are we really still using Ubuntu 16.04? That's surprising!

You should always use the latest base image for security.

I remember that specifying resource limits in the deployment.yaml is important for security, but I can't remember the exact syntax to use.

I believe we should avoid using `latest` tags in the Dockerfile, but I might be mixing that up with something else.

For the manifest file, I feel like I need to check the security context settings. I practiced a similar question, but I can't recall the exact fields to modify.

I think I remember that using a specific user instead of root in the Dockerfile is a best practice, but I'm not sure how to implement it correctly.

Hmm, this looks like a tricky one. I'll need to carefully review the Dockerfile and deployment.yaml files to identify the security/best-practice issues.

This question seems straightforward. I think the key is to focus on the program closure process and what could prevent it from being completed.

I'm a little confused by all the different syntax options here. I think option B with the DELIMITER AS ',' might work, but I'm not 100% sure. I'll need to carefully read through the question and think it through step-by-step.
