# 配置K8s Topology Manager

配置K8s Topology Manager，需要修改kubelet.service文件和kubelet配置文件。

1. 注释外层kubelet.service的ExecStart。若不注释，会提示“存在多个ExecStart”。

  a. 打开文件。
    1 vi /usr/lib/systemd/system/kubelet.service

  b. 按“i”进入编辑模式，在“ExecStart=/usr/bin/kubelet”前面加上#，将内容注释掉。
    1 #ExecStart=/usr/bin/kubelet

  c. 按“Esc”键退出编辑模式，输入:wq!，按“Enter”键保存并退出文件。
2. 修改kubelet配置文件，启用拓扑管理策略。
--topology-manager-policy可选：

  - single-numa-node
  - best-effort
  - restricted
  - none

  a. 打开文件。
    1 vi /usr/lib/systemd/system/kubelet.service.d/10-kubeadm.conf

    1 2 3 4 5 6 7 8 9 # Note: This dropin only works with kubeadm and kubelet v1.11+ [Service] Environment="KUBELET_KUBECONFIG_ARGS=--bootstrap-kubeconfig=/etc/kubernetes/bootstrap-kubelet.conf --kubeconfig=/etc/kubernetes/kubelet.conf" Environment="KUBELET_CONFIG_ARGS=--config=/var/lib/kubelet/config.yaml" # This is a file that "kubeadm init" and "kubeadm join" generates at runtime, populating the KUBELET_KUBEADM_ARGS variable dynamically EnvironmentFile=-/var/lib/kubelet/kubeadm-flags.env # This is a file that the user can use for overrides of the kubelet args as a last resort. Preferably, the user should use # the .NodeRegistration.KubeletExtraArgs object in the configuration files instead. KUBELET_EXTRA_ARGS should be sourced from this file. EnvironmentFile=-/etc/sysconfig/kubelet

  b. 修改点一：添加如下两行。
    1 2 ExecStartPre=/usr/bin/mkdir -p /sys/fs/cgroup/cpuset/system.slice/kubelet.service ExecStartPre=/usr/bin/mkdir -p /sys/fs/cgroup/hugetlb/system.slice/kubelet.service

  c. 修改点二：修改如下这行，添加CPU Manager和Topology Manager的配置开关。
    1 ExecStart=/usr/bin/kubelet $KUBELET_KUBECONFIG_ARGS $KUBELET_CONFIG_ARGS $KUBELET_KUBEADM_ARGS $KUBELET_EXTRA_ARGS --kube-reserved=cpu=2,memory=250Mi --cpu-manager-policy=static --feature-gates=CPUManager=true,TopologyManager=true --topology-manager-policy=single-numa-node

  d. 按“Esc”键退出编辑模式，输入:wq!，按“Enter”键保存并退出文件。
