I don't know, I'm kind of leaning towards option D. Pointing to the SHA256 digest seems like it might be a bit more robust, you know? It's not dependent on tags or anything like that. But I can see the appeal of C as well. Tough call.

Haha, can you imagine if we tried option B? 'Apply the latest tag to the previous container image'? That's like trying to put a fresh coat of paint on a broken-down car and expecting it to run better. No, I think C is the way to go. Keep it simple, you know?

Yeah, I agree with you there. Option C seems like the most straightforward approach. We know the previous version was working, so let's just build a new container from that and swap it in. I'm not a big fan of the other options - they seem like they might introduce more complexity than necessary.

Hmm, this is a tricky one. I'm not sure if I fully understand the context here. But from what I can gather, it seems like we need to revert to a previous, working version of the container image. I think option C might be the way to go - building a new container from a previous Git tag and doing a rolling update on the deployment.
