如何修改kubelet启动参数

小编给大家分享一下如何修改kubelet启动参数，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！

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]# lsbasic.target.wants  default.target.wants  kubelet.service    local-fs.target.wants    network-online.target.wants  sysinit.target.wantsdefault.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 kubeletroot      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
