### 测试在虚拟机上迁移 ###

##### 导入数据库到RDS #####

![format_png][]

##### 在虚拟机上启动测试 #####

./mm-wiki --conf conf/mm-wiki.conf

![format_png 1][]

没问题

![format_png 2][]

### 准备工作 ###

##### nfs创建 #####

略。。

##### 修改配置文件 #####

主要是调整静态文件的地址 数据库账号密码 端口号

![format_png 3][]

##### 拷贝静态文件到nfs的/opt/mm\_wiki下 用nfs 挂载 其余配置文件打进容器 #####

![format_png 4][]

##### 创建dockerfile #####

FROM harbor.aircourses.com/kubernetes/jdk-1.8.0_161:v1.1
    MAINTAINER PDABC Enterprise Container Images <hugo.xu@pdabc.com>
    
    COPY wiki /opt/wiki
    
    ENV LANG=en_US.UTF-8
    ENV LANGUAGE=en_US.UTF-8
    #ENTRYPOINT ["sh", "/opt/wiki/start.sh"]
    ENTRYPOINT ["sh", "/opt/mm_wiki/start.sh"]

### 迁移到k8s ###

##### 创建pv.yaml #####

##创建nfs-PV
    ---
    apiVersion: v1
    kind: PersistentVolume
    metadata:
      name: mm-wiki-pv
      namespace: default
      labels:
        pv: mm-wiki-pv
    spec:
      capacity:
        storage: 50Gi
      accessModes:
        - ReadWriteMany
      persistentVolumeReclaimPolicy: Retain
      nfs:
        path: /opt/mm_wiki
        server: 192.168.13.212

kubectl create -f pv.yaml

##### 创建pvc.yaml #####

##创建 mm-wiki-pvc
    ---
    kind: PersistentVolumeClaim
    apiVersion: v1
    metadata:
      name: mm-wiki-pvc
      namespace: default
    spec:
      accessModes:
        - ReadWriteMany
      resources:
        requests:
          storage: 50Gi
      selector:
        matchLabels:
          pv: mm-wiki-pv

kubectl create -f pvc.yaml

##### 创建deployment.yaml #####

apiVersion: apps/v1
    kind: Deployment
    metadata:
    # deployment名字 和svc 和ingress绑定没关系
      name: mm-wiki-dp
      namespace: default
    spec:
      replicas: 1
      # 在定义模板的时候必须定义labels,因为Deployment.spec.selector是必须字段,而他又必须和template.labels对应
      selector:
        matchLabels:
          app: mm-wiki
      # template里面定义的内容会应用到下面所有的副本集里面(例如depolyment下的pod),在template.spec.containers里面不能定义labels标签。可以kubectl get pods --show-labels查看
      template:
        metadata:
          labels:
            app: mm-wiki
        spec:
          containers:
          # containers名字 和svc 和ingress绑定没关系
          - name: mm-wiki
            image: harbor.aircourses.com/kubernetes/mm-wiki:v2.0
            volumeMounts:
            - mountPath: /opt/mm_wiki
              name: mm-wiki-data
            ports:
            - name: http
              containerPort: 80
          volumes:
          - name: mm-wiki-data
            persistentVolumeClaim:
              claimName: mm-wiki-pvc
          imagePullSecrets:
            - name: myregistrykey

kubectl apply -f deployment.yaml

##### 创建svc.yaml #####

apiVersion: v1
    kind: Service
    metadata:
      name: mm-wiki
      namespace: default
    spec:
      type: ClusterIP
      selector:
        app: mm-wiki
      ports:
      - name: http
        port: 80
        targetPort: 80

kubectl apply -f svc.yaml

##### 创建ingress.yaml #####

apiVersion: extensions/v1beta1
    kind: Ingress
    metadata:
    # 通过添加下面的annotations 来开启白名单
    # 关闭80强制跳转443 为ingress配置增加注解（annotations）：nginx.ingress.kubernetes.io/ssl-redirect: 'false' 就可以禁止http强制跳转至https
      annotations:
        nginx.ingress.kubernetes.io/whitelist-source-range: "60.191.70.64/29, 192.168.0.0/16, 47.111.185.111, 47.97.113.64, 47.99.246.58, 47.111.170.245, 47.111.247.117, 47.99.244.221, 47.110.144.233, 47.110.144.233, 121.41.103.54, 121.40.186.211, 121.40.16.165, 121.40.16.63, 60.191.70.66, 60.191.70.67"
        nginx.ingress.kubernetes.io/ssl-redirect: 'false'
      name: mm-wiki
    spec:
      tls:
       - hosts:
         - mm-wiki.aircourses.com
         secretName: aircourses
      rules:
        - host: mm-wiki.aircourses.com
          http:
            paths:
            - path: /
              backend:
                serviceName: mm-wiki
                servicePort: 80

kubectl apply -f ingress.yaml

### 中间出现了点小故障 ###

pod显示running 端口也启动了。但是访问的时候页面显示不正常，进入容器，用同一个脚本换一个端口启动就可以访问。

正常的请求如下

![format_png 5][]

访问有问题的请求返回如下

![format_png 6][]

直接起一个容器 映射配置文件和端口进去排查

docker run  -it -v /mm-wiki:/opt  --name=mm-wiki-06  harbor.aircourses.com/kubernetes/mm-wiki:v11 -p 80:80   /bin/sh

发现报错如下

直接curl ip+port 没有返回

![format_png 7][]

应该是需要在和views一级的目录下 启动项目，否则就会报错。代码应该是go写的，不太懂。排查了一小会 根据报错推测出来的。

启动脚本 修改到和views一级下面启动。 果然可以了
