Wait, so we can't just delete the managed instance group and recreate it? That seems like the simplest solution, but I guess it could cause downtime. Gotta love Terraform's idempotency!

Ah, I see. The key here is to minimize disruption to the application while updating the instance template. I think option B might be the best approach, but I'll need to double-check the details.

Hmm, this is a tricky one. I'm not sure I fully understand the issue with the instance template change causing the pipeline to fail. I'll need to carefully read through the options and think this through.
