GKE Autopilot: Minimum resource request and limit is too high!

[Hasibul Hasan]

Hello there!

I am trying out GKE Autopilot for our staging system. And the minimum resource limit and request is too high.

I can not set memory below 256Mib and CPU to 0.25. Why?

For staging environment, I do not need more that 0.1 vCPU for each container. Also for memory, I do not need more than 100Mib. 

So, how can I set my containers' resource request and limit to this minimum (0.1 vCPU and 128Mib memory)?

Thank you!

Hello,

GKE autopilot is a great way to reduce the operational cost and its built to optimize your cluster for production and yield higher workload availability and efficiency.

However, Its hard to fit all possible use cases even with our current level of flexibility. That being said, some built-in settings are immutable, please refer this table [1] to see the possible resource allocation with the GKE autopilot feature.

I also recommend you to fill a feature request [2] by explaining your use case and the product team will review you request.
