The Pod's effective request/limit for a resource is the higher of: the sum of all app containers request/limit for a resource the effective init request/limit for a resource Scheduling is done based on effective requests/limits, which means init containers can reserve resources for initialization that are not used during the life of the Pod. This means one can only create 2 pods in the default namespace. conf anymore it is not safe to rely on ulimit . This is the code I'm using to set the value:.
