Editor to share with you how to modify kubelet startup parameters, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

1. View kubelet startup parameters

K8s components are managed through systemctl, so they can be found in / etc/systemd/system

Find the relevant configuration files under

[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 14 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

As you can see, the parameters of the kubelet process are the same as the configuration file.

2. Modify startup parameters [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 above are all the contents of the article "how to modify kubelet startup parameters".
