什么是kubeedge:
KubeEdge是一個開源系統，用于將容器化應用程序編排功能擴展到Edge的主機。它基于kubernetes構建，并為網絡應用程序提供基礎架構支持。云和邊緣之間的部署和元數據同步。 KubeEdge使用Apache 2.0許可。并且絕對可以免費用于個人或商業用途。
kubeedge目標是創建一個開放平臺，使能邊緣計算，將容器化應用編排功能擴展到邊緣的節點和設備，后者基于kubernetes構建，并為云和邊緣之間的網絡，應用部署和元數據同步提供基礎架構支持。
下面我們來安裝一個可以實際操作的kubeedge環境！
一、環境準備，兩節點都需要配置
1.1、主機準備
|
主機名 |
IP地址 |
最低配置 |
操作系統 |
內核版本 |
|
cloudmaster |
10.139.8.210 |
2C 4G |
centos 7.6 |
3.10.0-957.el7.x86_64 |
|
cloudedge |
10.139.8.211 |
1C 2G |
CentOS 7.6 |
3.10.0-957.el7.x86_64 |
1.2、關閉防火墻和selinux
$ systemctl stop firewalld && systemctl disable firewalld
$ setenforce 0
$ cat /etc/selinux/config #將 SELINUX=enforcing 改為disable
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
1.3、關閉swap分區，若沒有swApp分區可以忽略不進行操作
$ swapoff -a
$ sed -i 's/.*swap.*/#&/' /etc/fstab
1.4、主機名解析
$ echo "10.139.8.210 cloudmaster" >> /etc/hosts
$ echo "10.139.8.211 cloudedge" >> /etc/hosts
二、kubeadm安裝kubernetes集群
2.1、安裝Docker (兩節點都需要安裝)
#1、安裝docker依賴軟件包
$ sudo yum install -y yum-utils device-mapper-persistent-data lvm2
#2、添加Yum源，國內源速度快很多
#國內源安裝快很多
$ sudo yum-config-manager
--add-repo https://mirrors.ustc.edu.cn/docker-ce/linux/centos/docker-ce.repo
#3、安裝docker-ce
$ yum install docker-ce docker-ce-cli containerd.io -y
$ systemctl start docker && systemctl enable docker
#4、驗證安裝是否成功
$ docker version
Client: Docker Engine - Community
Version: 20.10.6
API version: 1.41
Go version: go1.13.15
Git commit: 370c289

docker-init:
Version: 0.19.0
GitCommit: de40ad0
2.2、安裝k8s集群，只需要在cloudmaster上進行安裝，cloudedge不需要join到集群
#1、配置內核參數，將橋接的IPv4流量傳遞到iptables的鏈
$ cat > /etc/sysctl.d/k8s.conf <<EOF
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
EOF
$ sysctl --system
#2、配置國內kuberneetes的yum源，由于網絡原因，中國無法直接連接到google的網絡，需要配置阿里云的yum源
$ cat <<EOF > /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
enabled=1
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
EOF
#3、安裝kubectl、kubeadm、kubelet
$ yum install -y kubelet-1.17.1 kubeadm-1.17.1 kubectl-1.17.1
#4、初始化集群，在cloudmaster上執行kubeadm init
$ kubeadm init --kubernetes-version=1.17.1
--apiserver-advertise-address=10.139.8.210
--image-repository registry.aliyuncs.com/google_containers
--service-cidr=10.96.0.0/12
--pod-network-cidr=10.244.0.0/16
//以下是執行完畢后輸出的部分信息
Your Kubernetes control-plane has initialized successfully!
To start using your cluster, you need to run the following as a regular user:
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
https://kubernetes.io/docs/concepts/cluster-administration/addons/
Then you can join any number of worker nodes by running the following on each as root:
kubeadm join 192.168.100.150:6443 --token cxins6.pxbyomo4pp1mnrao
--discovery-token-ca-cert-hash sha256:35876ef6f2e5fe7eb5c7bb709dbd5e09d0e9e7d3adf41cbe708eec4fb586c8d6
#5、配置kubectl工具
$ mkdir -p /root/.kube
$ sudo cp /etc/kubernetes/admin.conf /root/.kube/config
$ sudo chown $(id -u):$(id -g) $HOME/.kube/config
#6、查看主節點狀態
$ NAME STATUS ROLES AGE VERSION
master NotReady master 27h v1.17.1
#7、部署flannel網絡
$ kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
三、安裝kubeedge集群
3.1、安裝CloudCore （在cloudmaster節點操作）
安裝有兩種方式，一種源碼編譯手動安裝，還有一種是使用ke提供的工具-keadm。手動安裝比較繁瑣，對于新手而言是一種很大的心智負擔，最好大家還是都用keadm這個工具去安裝，但是，這種方式安裝最大的問題就是國內的墻的問題會導致很多某些資源無法下載，比如說 CRD的yaml,cloudcore啟動的service，所以我會結合兩者，采用半手動半工具的安裝方式去完成ke的集群搭建。
#1、下載keadm
$ wget https://github.com/kubeedge/kubeedge/releases/download/v1.5.0/keadm-v1.5.0-linux-amd64.tar.gz
#解壓
$ tar -zxvf keadm-v1.5.0-linux-amd64.tar.gz
$ cd keadm-v1.5.0-linux-amd64/keadm && chmod +x keadm && mv keadm /usr/local/bin
#驗證keadm是否安裝成功
$ keadm version
version: version.Info{Major:"1", Minor:"5", GitVersion:"v1.5.0", GitCommit:"8b0913e04ef4ef826af6715d336e23a66e3774df", GitTreeState:"clean", BuildDate:"2020-11-13T08:04:56Z", GoVersion:"go1.15", Compiler:"gc", Platform:"linux/amd64"}
#2、使用keadm安裝cloudcore
keadm init --advertise-address=10.139.8.210 --kubeedge-version=1.5.0
Kubernetes version verification passed, KubeEdge installation will start...

Usage:
keadm init [flags]
Examples:
keadm init
- This command will download and install the default version of KubeEdge cloud component
keadm init --kubeedge-version=1.5.0 --kube-config=/root/.kube/config
- kube-config is the absolute path of kubeconfig which used to secure connectivity between cloudcore and kube-apiserver
Flags:
--advertise-address string Use this key to set IPs in cloudcore's certificate SubAltNames field. eg: 10.10.102.78,10.10.102.79
--domainname string Use this key to set domain names in cloudcore's certificate SubAltNames field. eg: www.cloudcore.cn,www.kubeedge.cn
-h, --help help for init
--kube-config string Use this key to set kube-config path, eg: $HOME/.kube/config (default "/root/.kube/config")
--kubeedge-version string Use this key to download and use the required KubeEdge version
--master string Use this key to set K8s master address, eg: http://127.0.0.1:8080
--tarballpath string Use this key to set the temp directory path for KubeEdge tarball, if not exist, download it

--advertise-address=xxx.xx.xx.xx 這里的xxx.xx.xx.xx換成master機器的ip,可以是內網地址，也可以是公網ip地址，--kubeedge-version=1.5.0 意思是指定安裝的ke的版本，如果你默認不指定那么keadm會自動去下載最新的版本。很遺憾，我在執行
keadm init --advertise-address=xxx.xx.xx.xx --kubeedge-version=1.5.0
命令的時候出錯了，這個錯的問題在于網絡被墻了，特別是在公有云的虛擬機上，出現這種問題的概率特別大，這種問題咋解決，一種是翻墻翻出去，另外一種是在/etc/hosts下添加如下內容

kubeedge-v1.5.0-linux-amd64.tar.gz
$ wget https://github.com/kubeedge/kubeedge/releases/download/v1.5.0/kubeedge-v1.5.0-linux-amd64.tar.gz
3.3、準備完成后進行初始化
$ keadm init --advertise-address=10.139.8.210 --kubeedge-version=1.5.0
Kubernetes version verification passed, KubeEdge installation will start...
Expected or Default KubeEdge version 1.5.0 is already downloaded and will checksum for it.
kubeedge-v1.5.0-linux-amd64.tar.gz checksum:

CloudCore started
如果你想把cloudcore交給systemed托管的話切記把cloudcore.service移到/etc/systemed/system下面然后再執行下systemctl daemon-reload
3.4、查看cloudedge加入集群的token
$ keadm gettoken
48ce0f652d396b56ce2b814a62fd85833e3b02273b374aca3d53557d98d375be.eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE2MjI2MDA3ODB9.JnW6PfLFEldpAZkNgoAe6Aaw2l0H11MtZIUjB1zfTk4
3.4、安裝edgecore
#安裝keadm命令
$ mkdir -p /etc/kubeedge && wget https://github.com/kubeedge/kubeedge/releases/download/v1.5.0/kubeedge-v1.5.0-linux-arm.tar.gz
#加入集群
$ keadm join --cloudcore-ipport=xx.xx.xx.xx:10000 --kubeedge-version=1.5.0 --token=<token>
-cloudcore-ipport表示的是cloudcore的對外暴露的ip就是公網ip了，如果你是在公有云服務器上的記得打開安全組的端口
--kubeedge-version就是ke的版本
--token= 這個token是上一步集群的token
3.5、檢查ke集群是否安裝完成
[root@master kubeedge]# kubectl get no
NAME STATUS ROLES AGE VERSION
cloudmaster Ready cloudmaster 27h v1.17.1
cloudedge Ready agent,edge 4h24m v1.19.3-kubeedge-v1.5.0
總結：kubeedge的安裝到此結束，有想學習的小伙伴快快開始吧，當然學習kubeedge之前最好先了解一下kubernetes技術，這樣不至于在操作的時候不知所措了。
