  I vote for A. A rolling update with maxSurge set to 0 ensures that no additional instances beyond the desired size are created during the update. By setting maxUnavailable to 1, only one instance is taken down at a time, minimizing the impact on the available capacity during the deployment. This approach allows the rolling deployment to proceed in a controlled manner, with each new version gradually replacing instances without decreasing the overall capacity and with zero downtime. Not Option B because setting maxSurge to 1 and maxUnavailable to 0, could lead to temporarily increased capacity during the update, and it might result in higher resource usage than necessary. This option may not guarantee zero downtime or minimize the impact on the available capacity during the deployment.
