kubeedge v1.1.0部署指南

1、准备工作

1.1 kubernetes集群和edge节点

需要先至少准备两台机器，一台master节点，一台edge节点。
为了方便验证，本此验证中master节点和edge节点的OS都是ubuntu 18.04。

1）先在master节点上安装kubernetes，可以只部署master
2）edge节点上安装docker
3）edge节点上安装mosquitto

kubernetes集群和docker的安装教程网上有很多，此处不再详述。

1.2 创建安装目录 (master节点)

mkdir -p /home/bluejoy/kubeedge/deploy-v1.1.0

1.3 下载kubeedge v1.1.0源码 (master节点)

cd /home/bluejoy/kubeedge/deploy-v1.1.0
git clone https://github.com/kubeedge/kubeedge.git
cd kubeedge
git checkout v1.1.0

1.4 下载 kubeedge 1.1.0 版本二进制包(master节点)

cd /home/bluejoy/kubeedge/deploy-v1.1.0
wget https://github.com/kubeedge/kubeedge/releases/download/v1.1.0/kubeedge-v1.1.0-linux-amd64.tar.gz
tar -xzvf kubeedge-v1.1.0-linux-amd64.tar.gz
mv kubeedge-v1.1.0-linux-amd64 kubeedge-v1.1.0
cp kubeedge/cloud/cloudcore /usr/local/bin/

2、kubeedge云端部分配置 (master节点)

2.1 kubeedge证书生成

cd /home/bluejoy/kubeedge/deploy-v1.1.0/kubeedge/build/tools/
bash certgen.sh genCertAndKey edge
tar -cvzf certs.tgz /etc/kubeedge/certs/

2.2 安装crds

kubectl create -f devices_v1alpha1_device.yaml
kubectl create -f devices_v1alpha1_devicemodel.yaml

2.3 修改配置文件：

mkdir /etc/kubeedge/cloudcore
cp -r /home/bluejoy/kubeedge/deploy-v1.1.0/kubeedge-v1.1.0/cloud/cloudcore/conf /etc/kubeedge/cloudcore/
export GOARCHAIUS_CONFIG_PATH=/etc/kubeedge/cloudcore
vim /etc/kubeedge/cloudcore/conf/controller.yaml

controller.yaml文件内容如下，主要修改两处地方：
1）master地址
2）kubeconfig文件所在的地址

controller:
  kube:
    master: "https://192.168.56.105:6443"    # kube-apiserver address (such as:http://localhost:8080)
    namespace: ""
    content_type: "application/vnd.kubernetes.protobuf"
    qps: 5
    burst: 10
    node_update_frequency: 10
    kubeconfig: "/root/.kube/config"   #Enter path to kubeconfig file to enable https connection to k8s apiserver, if master and kubeconfig are both set, master will override any value in kubeconfig.
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://192.168.56.105:6443"       # kube-apiserver address (such as:http://localhost:8080)
    namespace: ""
    content_type: "application/vnd.kubernetes.protobuf"
    qps: 5
    burst: 10
    kubeconfig: "/root/.kube/config" #Enter path to kubeconfig file to enable https connection to k8s apiserver,if master and kubeconfig are both set, master will override any value in kubeconfig.

2.4 启动cloudcore进程

cp /home/bluejoy/kubeedge/deploy-v1.1.0/kubeedge-v1.1.0/cloud/cloudcore/cloudcore /usr/local/bin/
cloudcore > /var/log/kubeedge/cloudcore.log

2.5、创建node

cd /home/bluejoy/kubeedge/deploy-v1.1.0/kubeedge/build/
vim node.json

{
  "kind": "Node",
  "apiVersion": "v1",
  "metadata": {
    "name": "bluejoy-jing",
    "labels": {
      "name": "edge-node",
      "node-role.kubernetes.io/edge": ""
    }
  }
}

执行下一步命令之前，请先修改node.json文件中的metadata.name的值为edge节点的hostname

# kubectl apply -f node.json

3、kubeedge边端部分配置

3.1 安装Mosquitto

1）添加 apt-get 源：

add-apt-repository ppa:mosquitto-dev/mosquitto-ppa
apt-get update

2）安装：

apt-get install mosquitto

3.2 拷贝证书(master节点)

scp -r /etc/kubeedge/certs [email protected]:/etc/kubeedge/

3.3 拷贝二进制程序(master节点)

scp -r /home/bluejoy/kubeedge/deploy-v1.1.0/kubeedge-v1.1.0 [email protected]:/etc/kubeedge/

3.4 修改edgecore的配置文件(edge节点)

vim /etc/kubeedge/kubeedge-v1.1.0/edge/conf/edge.yaml

根据自己的情况，修改以下部分的内容：
1）edgehub.websocket.url中的IP地址和edge节点的主机名称
2）edgehub.controller.node-id的值为edge节点的主机名称
3）edged.hostname-override的值为edge节点的主机名称
4）edged.interface-name的值根据edge节点的网络接口的名称进行修改，我的是enp0s8
5）edged.cgroup-driver根据edged节点上的实际值进行修改（可以通过docker info命令查看具体的值）

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.

3.5 启动edgecore进程 （dege节点）

export GOARCHAIUS_CONFIG_PATH=/etc/kubeedge/kubeedge-v1.1.0/edge
cp /etc/kubeedge/kubeedge-v1.1.0/edge/edgecore /usr/local/bin
edgecore > /var/log/kubeedge/edgecore.log

4、验证部署结果（master节点）

4.1 查看edge节点是否ready

4.2 部署一个deployment进行验证

kubectl apply -f /home/bluejoy/kubeedge/deploy-v1.1.0/kubeedge/build/deployment.yaml

4.3 删除deployment

kubectl delete -f /home/bluejoy/kubeedge/deploy-v1.1.0/kubeedge/build/deployment.yaml
