[CloudNative:KuberNetes&二进制部署.V13] [Applications.KuberNetes][|DevOps|k8s|**5节点**|二进制1.20|kubernetes-node组件配置|——|kubelet|kube-proxy|]
一、kube-proxy配置
### --- kube-proxy注意事项
~~~ # 注意,如果不是高可用集群,192.168.1.20:8443改为master01的地址,
~~~ # 8443改为apiserver的端口,默认是6443
二、创建kube-proxy服务
### --- 创建kube-proxy服务
~~~ # 创建kube-proxy服务;以下操作在Master01执行
[root@k8s-master01 ~]# cd /root/k8s-ha-install
~~~ # 创建ServiceAccount
[root@k8s-master01 k8s-ha-install]# kubectl -n kube-system create serviceaccount kube-proxy
~~~ 输出结果:
serviceaccount/kube-proxy created
~~~ # 创建ClusterRoleBinding
[root@k8s-master01 k8s-ha-install]# kubectl create clusterrolebinding system:kube-proxy --clusterrole system:node-proxier --serviceaccount kube-system:kube-proxy
~~~ 输出结果:
clusterrolebinding.rbac.authorization.k8s.io/system:kube-proxy created
~~~ # 创建cluster
[root@k8s-master01 k8s-ha-install]# SECRET=$(kubectl -n kube-system get sa/kube-proxy \
--output=jsonpath='{.secrets[0].name}')
[root@k8s-master01 k8s-ha-install]# JWT_TOKEN=$(kubectl -n kube-system get secret/$SECRET \
--output=jsonpath='{.data.token}' | base64 -d)
[root@k8s-master01 k8s-ha-install]# PKI_DIR=/etc/kubernetes/pki
[root@k8s-master01 k8s-ha-install]# K8S_DIR=/etc/kubernetes
[root@k8s-master01 k8s-ha-install]# kubectl config set-cluster kubernetes --certificate-authority=/etc/kubernetes/pki/ca.pem --embed-certs=true --server=https://192.168.1.20:8443 --kubeconfig=${K8S_DIR}/kube-proxy.kubeconfig
~~~ 输出结果:
Cluster "kubernetes" set.
~~~ # 创建user
[root@k8s-master01 k8s-ha-install]# kubectl config set-credentials kubernetes --token=${JWT_TOKEN} --kubeconfig=/etc/kubernetes/kube-proxy.kubeconfig
~~~ 输出结果:
User "kubernetes" set.
~~~ # 创建context
[root@k8s-master01 k8s-ha-install]# kubectl config set-context kubernetes --cluster=kubernetes --user=kubernetes --kubeconfig=/etc/kubernetes/kube-proxy.kubeconfig
~~~ 输出结果:
Context "kubernetes" created.
~~~ # 创建context
[root@k8s-master01 k8s-ha-install]# kubectl config use-context kubernetes --kubeconfig=/etc/kubernetes/kube-proxy.kubeconfig
~~~ 输出结果:
Switched to context "kubernetes".
### --- 修改pod的网段
~~~ # 查看pod的网段
~~~ 注:修改pod的网段
~~~ 注:如果更改了集群Pod的网段,需要更改kube-proxy/kube-proxy.conf的clusterCIDR: 172.16.0.0/12参数为pod的网段。
[root@k8s-master01 ~]# vim kube-proxy/kube-proxy.conf
clusterCIDR: 172.16.0.0/12
### --- 在master01将kube-proxy的systemd Service文件发送到其他节点;将配置文件发送到其它节点
~~~ # 将kube-proxy配置文件发送到k8s-master节点
[root@k8s-master01 k8s-ha-install]# for NODE in k8s-master01 k8s-master02 k8s-master03; do
scp ${K8S_DIR}/kube-proxy.kubeconfig $NODE:/etc/kubernetes/kube-proxy.kubeconfig
scp kube-proxy/kube-proxy.conf $NODE:/etc/kubernetes/kube-proxy.conf
scp kube-proxy/kube-proxy.service $NODE:/usr/lib/systemd/system/kube-proxy.service
done
~~~ 注:输出结果:
kube-proxy.kubeconfig 100% 3120 1.6MB/s 00:00
kube-proxy.conf 100% 813 143.0KB/s 00:00
kube-proxy.service 100% 288 16.4KB/s 00:00
kube-proxy.kubeconfig 100% 3120 473.7KB/s 00:00
kube-proxy.conf 100% 813 210.8KB/s 00:00
kube-proxy.service 100% 288 106.8KB/s 00:00
kube-proxy.kubeconfig 100% 3120 506.0KB/s 00:00
kube-proxy.conf 100% 813 185.6KB/s 00:00
kube-proxy.service
~~~ # 将kube-proxy配置文件发送到k8s-node节点
[root@k8s-master01 k8s-ha-install]# for NODE in k8s-node01 k8s-node02; do
scp /etc/kubernetes/kube-proxy.kubeconfig $NODE:/etc/kubernetes/kube-proxy.kubeconfig
scp kube-proxy/kube-proxy.conf $NODE:/etc/kubernetes/kube-proxy.conf
scp kube-proxy/kube-proxy.service $NODE:/usr/lib/systemd/system/kube-proxy.service
done
~~~ 注:输出结果:
kube-proxy.kubeconfig 100% 3120 322.1KB/s 00:00
kube-proxy.conf 100% 813 118.2KB/s 00:00
kube-proxy.service 100% 288 54.6KB/s 00:00
kube-proxy.kubeconfig 100% 3120 515.4KB/s 00:00
kube-proxy.conf 100% 813 185.4KB/s 00:00
kube-proxy.service
三、启动kube-proxy并设置开机自启动### --- 所有节点启动kube-proxy并设置开机自启动
### --- 所有节点启动kube-proxy
[root@k8s-master01 k8s-ha-install]# systemctl daemon-reload
[root@k8s-master01 k8s-ha-install]# systemctl enable --now kube-proxy
Created symlink from /etc/systemd/system/multi-user.target.wants/kube-proxy.service to /usr/lib/systemd/system/kube-proxy.service.
### --- 查看kube-proxy状态
[root@k8s-master01 k8s-ha-install]# systemctl status kube-proxy
Active: active (running) since Wed 2021-05-12 21:10:55 CST; 14s ago
