            # NOTE: 目前对 tiup 的支持是将 pod 当做虚拟机使用，如果节点占用内存接近 request.memory 时，可能会导致 pod 被 oom killed，导致测试集群无法恢复(因为 tiup 用的 ssh key，systemd service 等被删除)
            # Workaround 是: 1. 对于中控机节点，适当调大 requests.memory 值 (中控机上跑了 haproxy，会有一定的资源占用)
            # 2. 对于 component 节点，配置 requests.memory 的同时也配置 tiup 拓扑里的 resource_control, 保证每个节点的 request.memory > resource_control.memory_limit (此时内存占用过高时，component 进程会被 systemd killed 而不会影响到 pod)
            # resource_control 的配置方式见： https://github.com/pingcap/tiup/blob/01843be5957ee189ff8cad0bb8cf2f0669cf3ddc/embed/examples/cluster/topology.example.yaml?_pjax=%23js-repo-pjax-container%2C%20div%5Bitemtype%3D%22http%3A%2F%2Fschema.org%2FSoftwareSourceCode%22%5D%20main%2C%20%5Bdata-pjax-container%5D#L19-L28
