I'm trying to figure out how to maintain 100% uptime for my application, but I'm running into challenges with RollingUpdate deployments that use ReadWriteOnce (RWO) persistent volume claims (PVCs). The issue is that RWO limits me to only one pod accessing the storage at any given time, which blocks the ability to perform a standard RollingUpdate without downtime. I really want to avoid switching to StatefulSets or using ReadWriteMany (RWX) access mode. Does anyone have suggestions on how I could manage to keep everything running smoothly without any disruptions?

With RWO, you're constrained because you can't have overlapping pods. This means getting to a point of 100% uptime is quite impossible without changing some constraints. You might want to look into adjusting your strategy instead of trying to achieve that uptime directly under current limitations.
