大家好，又见面了，我是你们的朋友全栈君。

kubeedge 安装部署（适用于Ubuntu）

  • 基础环境：安装了Ubuntu 18.04操作系统的两台虚拟机 (查看操作系统版本命令：cat /etc/os-release)

  • 部署kubeedge1.1.0版本

  • 根据keadm源码安装部署步骤整理(无法直接使用keadm工具完成部署)

一、配置源,写入以下内容到 /etc/apt/sources.list

root@ubuntu:~# cat /etc/apt/sources.list
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

root@ubuntu:~# apt-get update

二、安装 docker

root@ubuntu:~# apt-get update
root@ubuntu:~# 
root@ubuntu:~# curl -fsSL https://download.docker.com/linux/ubuntu/gpg | apt-key add
OK
root@intellif-edge:~# cat /etc/apt/sources.list.d/docker.list 
deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable
root@ubuntu:~# 
root@intellif-edge:~# apt-get install -y apt-transport-https ca-certificates curl gnupg-agent software-properties-common
root@ubuntu:~# apt-cache madison 'docker-ce' | grep 19.03.4 | head -1 | awk '{$1=$1};1' | cut -d' ' -f 3
5:19.03.4~3-0~ubuntu-bionic
root@ubuntu:~# 
root@ubuntu:~# apt-get install -y --allow-change-held-packages --allow-downgrades docker-ce=5:19.03.4~3-0~ubuntu-bionic
root@ubuntu:~# 
root@ubuntu:~# systemctl enable docker

三、安装 kubeadm kubelet kubectl

root@ubuntu:~# cat /etc/apt/sources.list.d/kubernetes.list 
deb https://mirrors.aliyun.com/kubernetes/apt/ kubernetes-xenial main
root@ubuntu:~# 
root@ubuntu:~# curl https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | apt-key add -
root@ubuntu:~# apt-get update

root@ubuntu:~# apt-cache madison 'kubeadm' | grep 1.16.2 | head -1 | awk '{$1=$1};1' | cut -d' ' -f 3
1.16.2-00
root@ubuntu:~# apt-get install -y --allow-change-held-packages --allow-downgrades kubeadm=1.16.2-00 kubelet=1.16.2-00 kubectl=1.16.2-00

四、kubeedge证书生成

  1. 准备生成证书脚本，将如下生成证书的脚本写入到/etc/kubeedge/certgen.sh
#!/bin/sh

readonly caPath=${CA_PATH:-/etc/kubeedge/ca}
readonly caSubject=${CA_SUBJECT:-/C=CN/ST=Zhejiang/L=Hangzhou/O=KubeEdge/CN=kubeedge.io}
readonly certPath=${CERT_PATH:-/etc/kubeedge/certs}
readonly subject=${SUBJECT:-/C=CN/ST=Zhejiang/L=Hangzhou/O=KubeEdge/CN=kubeedge.io}

genCA() { 
   
    openssl genrsa -des3 -out ${caPath}/rootCA.key -passout pass:kubeedge.io 4096
    openssl req -x509 -new -nodes -key ${caPath}/rootCA.key -sha256 -days 3650 \
    -subj ${subject} -passin pass:kubeedge.io -out ${caPath}/rootCA.crt
}

ensureCA() { 
   
    if [ ! -e ${caPath}/rootCA.key ] || [ ! -e ${caPath}/rootCA.crt ]; then
        genCA
    fi
}

ensureFolder() { 
   
    if [ ! -d ${caPath} ]; then
        mkdir -p ${caPath}
    fi
    if [ ! -d ${certPath} ]; then
        mkdir -p ${certPath}
    fi
}

genCertAndKey() { 
   
    ensureFolder
    ensureCA
    local name=$1
    openssl genrsa -out ${certPath}/${name}.key 2048
    openssl req -new -key ${certPath}/${name}.key -subj ${subject} -out ${certPath}/${name}.csr
    openssl x509 -req -in ${certPath}/${name}.csr -CA ${caPath}/rootCA.crt -CAkey ${caPath}/rootCA.key \
    -CAcreateserial -passin pass:kubeedge.io -out ${certPath}/${name}.crt -days 365 -sha256
}

buildSecret() { 
   
    local name="edge"
    genCertAndKey ${name} > /dev/null 2>&1
    cat <<EOF apiVersion: v1 kind: Secret metadata: name: cloudcore namespace: kubeedge labels: k8s-app: kubeedge kubeedge: cloudcore stringData: rootCA.crt: | $(pr -T -o 4 ${ 
     caPath}/rootCA.crt) edge.crt: | $(pr -T -o 4 ${ 
     certPath}/${ 
     name}.crt) edge.key: | $(pr -T -o 4 ${ 
     certPath}/${ 
     name}.key) EOF
}

$1 $2
  1. 生成证书、压缩证书
root@ubuntu:/etc/kubeedge# chmod +x certgen.sh 
root@ubuntu:/etc/kubeedge# bash certgen.sh genCertAndKey edge
root@ubuntu:/etc/kubeedge# tar -cvzf certs.tgz certs/

五、启动 Kubernetes

1、使用kubeadm部署k8s

root@ubuntu:/etc/kubeedge# swapoff -a && kubeadm init --image-repository "registry.cn-hangzhou.aliyuncs.com/google_containers" --pod-network-cidr=100.64.0.0/10
root@ubuntu:/etc/kubeedge# 
root@ubuntu:/etc/kubeedge# kubectl get pod --all-namespaces -o wide
The connection to the server localhost:8080 was refused - did you specify the right host or port?
root@ubuntu:/etc/kubeedge# 
root@ubuntu:/etc/kubeedge# mkdir -p $HOME/.kube && cp -r /etc/kubernetes/admin.conf $HOME/.kube/config && sudo chown $(id -u):$(id -g) $HOME/.kube/config
root@ubuntu:/etc/kubeedge# kubectl get pod --all-namespaces -o wide
NAMESPACE     NAME                             READY   STATUS    RESTARTS   AGE     IP              NODE     NOMINATED NODE   READINESS GATES
kube-system   coredns-67c766df46-7wrjq         0/1     Pending   0          11m     <none>          <none>   <none>           <none>
kube-system   coredns-67c766df46-kjffq         0/1     Pending   0          11m     <none>          <none>   <none>           <none>
kube-system   etcd-ubuntu                      1/1     Running   0          10m     192.168.11.56   ubuntu   <none>           <none>
kube-system   kube-apiserver-ubuntu            1/1     Running   0          10m     192.168.11.56   ubuntu   <none>           <none>
kube-system   kube-controller-manager-ubuntu   1/1     Running   0          9m55s   192.168.11.56   ubuntu   <none>           <none>
kube-system   kube-proxy-dcvz6                 1/1     Running   0          11m     192.168.11.56   ubuntu   <none>           <none>
kube-system   kube-scheduler-ubuntu            1/1     Running   0          10m     192.168.11.56   ubuntu   <none>           <none>
root@ubuntu:/etc/kubeedge#

2、修改kubelet启动参数，不适用cni插件

root@ubuntu:/var/lib/kubelet# cat /var/lib/kubelet/kubeadm-flags.env 
KUBELET_KUBEADM_ARGS="--cgroup-driver=cgroupfs --pod-infra-container-image=registry.cn-hangzhou.aliyuncs.com/google_containers/pause:3.1 --resolv-conf=/run/systemd/resolve/resolv.conf"
#KUBELET_KUBEADM_ARGS="--cgroup-driver=cgroupfs --network-plugin=cni --pod-infra-container-image=registry.cn-hangzhou.aliyuncs.com/google_containers/pause:3.1 --resolv-conf=/run/systemd/resolve/resolv.conf"
root@ubuntu:/var/lib/kubelet# systemctl restart kubelet

六、启动 kubeedge 云端部分 cloudcore

  1. 下载 kubeedge 1.1.0 版本安装包
root@ubuntu:~# mkdir -p /etc/kubeedge/
root@ubuntu:~# cd /etc/kubeedge
root@ubuntu:/etc/kubeedge# wget -k --no-check-certificate https://github.com/kubeedge/kubeedge/releases/download/v1.1.0/kubeedge-v1.1.0-linux-amd64.tar.gz
root@ubuntu:/etc/kubeedge# tar -C /etc/kubeedge/ -xzvf kubeedge-v1.1.0-linux-amd64.tar.gz
root@ubuntu:/etc/kubeedge# mv kubeedge-v1.1.0-linux-amd64 kubeedge
root@ubuntu:/etc/kubeedge# cp kubeedge/cloud/cloudcore /usr/local/bin/.
  1. 修改配置 cloudcore的 文件/etc/kubeedge/kubeedge/cloud/cloudcore/conf/controller.yaml
controller:
  kube:
    master: https://192.168.11.56:6443 # 修改为对应IP
    namespace: ""
    content_type: "application/vnd.kubernetes.protobuf"
    qps: 5
    burst: 10
    node_update_frequency: 10
    kubeconfig: "/root/.kube/config"   
cloudhub:
  protocol_websocket: true # enable websocket protocol
  port: 10000 # open port for websocket server
  protocol_quic: true # enable quic protocol
  quic_port: 10001 # open prot for quic server
  max_incomingstreams: 10000 # the max incoming stream for quic server
  enable_uds: true # enable unix domain socket protocol
  uds_address: unix:///var/lib/kubeedge/kubeedge.sock # unix domain socket address
  address: 0.0.0.0
  ca: /etc/kubeedge/ca/rootCA.crt
  cert: /etc/kubeedge/certs/edge.crt
  key: /etc/kubeedge/certs/edge.key
  keepalive-interval: 30
  write-timeout: 30
  node-limit: 10
devicecontroller:
  kube:
    master: https://192.168.11.56:6443 # 修改为对应IP
    namespace: ""
    content_type: "application/vnd.kubernetes.protobuf"
    qps: 5
    burst: 10
    kubeconfig: "/root/.kube/config"
  1. 启动cloudcore进程
root@ubuntu:/etc/kubeedge/kubeedge/cloud/cloudcore# cp /etc/kubeedge/kubeedge/cloud/cloudcore/cloudcore /usr/local/bin/.
root@ubuntu:/etc/kubeedge/kubeedge/cloud/cloudcore# export GOARCHAIUS_CONFIG_PATH=/etc/kubeedge/kubeedge/cloud/cloudcore
root@ubuntu:/etc/kubeedge/kubeedge/cloud/cloudcore# chmod +x /usr/local/bin/cloudcore && cloudcore > /etc/kubeedge/kubeedge/cloud/cloudcore/cloudcore.log 2>&1 &

七、启动 kubeedge 边缘部分 edgecore

  1. 修改配置 edgecore的配置文件/etc/kubeedge/kubeedge/edge/conf/edge.yaml
    可以统一替换: fb4ebb70-2783-42b8-b3ef-63e2fd6d242e (节点名称)
mqtt:
    server: tcp://127.0.0.1:1883 # external mqtt broker url.
    internal-server: tcp://127.0.0.1:1884 # internal mqtt broker url.
    mode: 0 # 0: internal mqtt broker enable only. 1: internal and external mqtt broker enable. 2: external mqtt broker enable only.
    qos: 0 # 0: QOSAtMostOnce, 1: QOSAtLeastOnce, 2: QOSExactlyOnce.
    retain: false # if the flag set true, server will store the message and can be delivered to future subscribers.
    session-queue-size: 100 # A size of how many sessions will be handled. default to 100.

edgehub:
    websocket:
        url: wss://0.0.0.0:10000/e632aba927ea4ac2b575ec1603d56f10/fb4ebb70-2783-42b8-b3ef-63e2fd6d242e/events
        certfile: /etc/kubeedge/certs/edge.crt
        keyfile: /etc/kubeedge/certs/edge.key
        handshake-timeout: 30 #second
        write-deadline: 15 # second
        read-deadline: 15 # second
    quic:
        url: 127.0.0.1:10001
        cafile: /etc/kubeedge/ca/rootCA.crt
        certfile: /etc/kubeedge/certs/edge.crt
        keyfile: /etc/kubeedge/certs/edge.key
        handshake-timeout: 30 #second
        write-deadline: 15 # second
        read-deadline: 15 # second
    controller:
        protocol: websocket # websocket, quic
        heartbeat: 15  # second
        project-id: e632aba927ea4ac2b575ec1603d56f10
        node-id: fb4ebb70-2783-42b8-b3ef-63e2fd6d242e

edged:
    register-node-namespace: default
    hostname-override: fb4ebb70-2783-42b8-b3ef-63e2fd6d242e
    interface-name: eth0
    edged-memory-capacity-bytes: 7852396000
    node-status-update-frequency: 10 # second
    device-plugin-enabled: false
    gpu-plugin-enabled: false
    image-gc-high-threshold: 80 # percent
    image-gc-low-threshold: 40 # percent
    maximum-dead-containers-per-container: 1
    docker-address: unix:///var/run/docker.sock
    runtime-type: docker
    remote-runtime-endpoint: unix:///var/run/dockershim.sock
    remote-image-endpoint: unix:///var/run/dockershim.sock
    runtime-request-timeout: 2
    podsandbox-image: kubeedge/pause:3.1 # kubeedge/pause:3.1 for x86 arch , kubeedge/pause-arm:3.1 for arm arch, kubeedge/pause-arm64 for arm64 arch
    image-pull-progress-deadline: 60 # second
    cgroup-driver: cgroupfs
    node-ip: ""
    cluster-dns: ""
    cluster-domain: ""

mesh:
    loadbalance:
        strategy-name: RoundRobin

2、创建node,启动edgecore进程

root@ubuntu:# kubectl apply -f node.json

node.json内容（注意 metadata.name 需要和 edge.yaml 中一致）

{ 
   
  "kind": "Node",
  "apiVersion": "v1",
  "metadata": { 
   
    "name": "fb4ebb70-2783-42b8-b3ef-63e2fd6d242e",
    "labels": { 
   
      "name": "edge-node",
      "node-role.kubernetes.io/edge": ""
    }
  }
}


root@ubuntu:/etc/kubeedge/kubeedge/edge/conf# export GOARCHAIUS_CONFIG_PATH=/etc/kubeedge/kubeedge/edge && edgecore > /etc/kubeedge/kubeedge/edge/edgecore.log 2>&1 &
