1、查看 kubelet 启动参数
k8s 组件是通过 systemctl 来管理的，因此可以在 /etc/systemd/system
下查找相关配置文件
[root@zhdj01 system]# ls
basic.target.wants default.target.wants kubelet.service local-fs.target.wants network-online.target.wants sysinit.target.wants
default.target getty.target.wants kubelet.service.d multi-user.target.wants sockets.target.wants system-update.target.wants
[root@zhdj01 system]# cat kubelet.service.d/10-kubeadm.conf
[Service]
Environment= KUBELET_KUBECONFIG_ARGS=--bootstrap-kubeconfig=/etc/kubernetes/bootstrap-kubelet.conf --kubeconfig=/etc/kubernetes/kubelet.conf
Environment= KUBELET_SYSTEM_PODS_ARGS=--pod-manifest-path=/etc/kubernetes/manifests --allow-privileged=true
Environment= KUBELET_NETWORK_ARGS=--network-plugin=cni --cni-conf-dir=/etc/cni/net.d --cni-bin-dir=/opt/cni/bin
Environment= KUBELET_DNS_ARGS=--cluster-dns=10.96.0.10 --cluster-domain=cluster.local
Environment= KUBELET_AUTHZ_ARGS=--authorization-mode=Webhook --client-ca-file=/etc/kubernetes/pki/ca.crt
Environment= KUBELET_CADVISOR_ARGS=--cadvisor-port=0
Environment= KUBELET_CGROUP_ARGS=--cgroup-driver=cgroupfs
Environment= KUBELET_CERTIFICATE_ARGS=--rotate-certificates=true --cert-dir=/var/lib/kubelet/pki
ExecStart=
ExecStart=/usr/bin/kubelet $KUBELET_KUBECONFIG_ARGS $KUBELET_SYSTEM_PODS_ARGS $KUBELET_NETWORK_ARGS $KUBELET_DNS_ARGS $KUBELET_AUTHZ_ARGS $KUBELET_CADVISOR_ARGS $KUBELET_CGROUP_ARGS $KUBELET_CERTIFICATE_ARGS $KUBELET_EXTRA_ARGS
[root@zhdj01 system]# ps -ef|grep kubelet
root 25323 1 4 Feb27 ? 1-11:45:14 /usr/bin/kubelet --bootstrap-kubeconfig=/etc/kubernetes/bootstrap-kubelet.conf --kubeconfig=/etc/kubernetes/kubelet.conf --pod-manifest-path=/etc/kubernetes/manifests --allow-privileged=true --network-plugin=cni --cni-conf-dir=/etc/cni/net.d --cni-bin-dir=/opt/cni/bin --cluster-dns=10.96.0.10 --cluster-domain=cluster.local --authorization-mode=Webhook --client-ca-file=/etc/kubernetes/pki/ca.crt --cadvisor-port=0 --cgroup-driver=cgroupfs --rotate-certificates=true --cert-dir=/var/lib/kubelet/pki可以看到，kubelet 进程的参数与配置文件一致。
2、修改启动参数
[root@zhdj01 system]# vi kubelet.service.d/10-kubeadm.conf
[root@zhdj01 system]# systemctl stop kubelet
[root@zhdj01 system]# systemctl daemon-reload
[root@zhdj01 system]# systemctl start kubelet以上是“如何修改 kubelet 启动参数”这篇文章的所有内容，感谢各位的阅读！相信大家都有了一定的了解，希望分享的内容对大家有所帮助，如果还想学习更多知识，欢迎关注丸趣 TV 行业资讯频道！
