Hmm, let me think about this. I need to keep the old version running while the new one is deployed. Yep, Option B is the winner!

I'm not sure about this. Doesn't the Recreate strategy mean the old version will be completely replaced? I think the RollingUpdate is the better choice here.

Option B looks good to me. Maintaining the previous replicas while deploying the new version is exactly what I need.

But wouldn't setting maxSurge to 0 ensure that we deploy at least 1 replica of the new version before removing the old ones?

I disagree, I believe setting the Deployment strategy to RollingUpdate with maxSurge set to 1, maxUnavailable set to 0 is the better option.
