I disagree, sometimes older images are more stable for production.

Don't forget to set user permissions properly in the Dockerfile!

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.

Okay, let's see what we've got here. The instructions mention fixing two issues in each file, so I'll need to be thorough in my analysis.

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.
