Kubernetes上的API部署，未创建Pod

Question

我正在kubernetes上部署APi，但POD并没有出错：

unable to ensure pod container exists: failed to create container for [kubepods burstable pod63951ed1-a42f-44c9-9f85-fbb4c06a3e83] : mkdir /sys/fs/cgroup/memory/kubepods/burstable/pod63951ed1-a42f-44c9-9f85-fbb4c06a3e83: cannot allocate memory
