【Kubeedge小白安装教程】Centos7.9+K8Sv1.22.2(kubeadm)+Kubeedgev1.10.0部署教程详解

1.需要有一个集群，最少保证是1个master和一个node

[root@k8s-ke-cloud ~]# kubectl get nodes -o wide

[root@k8s-ke-cloud ~]# kubectl get pods -n kube-system

2. KubeEdge v1.10.0部署安装

在k8s 1.22.2上几乎可以装各种版本的KubeEdge，因此不想装v1.10.0的也可以自行替换版本号。

首先，我们要在准备好的所有节点上下载kubeedege相关组件：

# keadm，类似kubeadm的KE部署包
cd /root/
wget https://github.com/kubeedge/kubeedge/releases/download/v1.10.0/keadm-v1.10.0-linux-amd64.tar.gz

tar -xvf keadm-v1.10.0-linux-amd64.tar.gz
cp keadm-v1.10.0-linux-amd64/keadm/keadm /usr/bin/

keadm version

# 提前下载kubeedge压缩包和校验文件
mkdir -p /etc/kubeedge/  && cd  /etc/kubeedge

wget https://github.com/kubeedge/kubeedge/releases/download/v1.10.0/kubeedge-v1.10.0-linux-amd64.tar.gz

wget https://github.com/kubeedge/kubeedge/releases/download/v1.10.0/checksum_kubeedge-v1.10.0-linux-amd64.tar.gz.txt

#然后即可在云节点进行边缘集群初始化：

keadm init --advertise-address=114.115.166.230 --kubeedge-version=1.10.0  #这个IP如果是公有云测试公网IP，其他的则是master节点的IP，这里的kubeedge-version版本一定要和你安装的版本一致

#可以用下面语句查看cloudcore进程是否已经在进行：
ps -ef|grep cloudcore  #必须要查询到进程

#为了防止以后挂机重开之后还要再重启服务，将cloudcore相关设施也加入开机自启动：
cd  /etc/kubeedge
cp /etc/kubeedge/cloudcore.service /etc/systemd/system/
systemctl daemon-reload
systemctl start cloudcore.service
systemctl enable cloudcore.service

#然后可以生成云节点的token，通过Token可以让其他边缘节点加入：
keadm gettoken

[root@k8s-ke-cloud ~]# keadm version
