## 第六章——在K8S中集成Apollo配置中心

> **前言**：
>
> **运维八荣八耻**：
>
> - 以可配置为荣，以硬编码为耻
> - 以互备为荣，以单点为耻
> - 以随时重启为荣，以不能迁移为耻
> - 以整体交付为荣，以部分交付为耻
> - 以无状态为荣，以有状态为耻
> - 以标准化为荣，以特殊化为耻
> - 以自动化工具为荣，以手动和人肉为耻
> - 以无人值守为荣，以人工介入为耻
>
> **目前我们交付进K8S集群的两个dubbo微服务和monitor，它们的配置都是写死在容器里的**
>
> **配置管理的现状**：
>
> - 配置散乱格式不标准（XML、ini、conf、yaml...）
> - 主要采用本地静态配置，应用多副本集下配置修改麻烦
> - 易引发生产事故（测试环境、生产环境配置混用）
> - 配置缺乏安全审计和版本控制功能（config review）
> - 不同环境的应用，配置不同，造成多次打包，测试失败
>
> **配置中心是什么？**：
>
> - 顾名思义，就是集中管理应用程序配置的“中心”

> 常见的配置中心：
>
> - SprigCloudConfig
> - K8S ConfigMap
> - Apollo：基于SprigCloudConfig
> - ...
>
> 目前具有争议的一般是使用Apollo还是SprigCloudConfig，看对比图，所以我们使用Apollo，而且Apollo是基于SprigCloudConfig，也就是你交付了Apollo也相当于交付了微服务

### configmap使用详解

> **WHAT**：就是为了让镜像 和 配置文件解耦，以便实现镜像的可移植性和可复用性，因为一个configMap其实就是一系列配置信息的集合，将来可直接注入到Pod中的容器使用
>
> **WHY**：为了配合Apollo使用

使用configmap管理应用配置，需要先拆分环境，拆分未test和pro环境来模拟实际工作

先把dubbo的服务（消费者/服务站/监视者）都scale成0，这样就没有容器在里面跑了

![1583162321302](assets/1583162321302.png)

![1583162339688](assets/1583162339688.png)

拆分zk成测试环境和生产环境来模拟实际情况，如下：

| 主机名            | 角色                 | ip        |
| ----------------- | -------------------- | --------- |
| HDSS7-11.host.com | zk1.od.com(Test环境) | 10.4.7.11 |
| HDSS7-12.host.com | zk2.od.com(Prod环境) | 10.4.7.12 |

之前是11、12、21一共3台，我们先把21拆了

~~~
# 11/12/21机器，停掉zookeeper并删掉相关data文件和log文件的内容：
~]# cd /opt/zookeeper
zookeeper]# bin/zkServer.sh stop
# 停不掉就 kill -9 id 杀掉
zookeeper]# ps aux|grep zoo
zookeeper]# cd /data/zookeeper/data/
data]# rm -fr ./*
cd ../logs/
logs]# rm -fr ./*
~~~

> **kill -9**：强制杀死该进程

# 11/12机器，修改zoo.cfg配置：
zookeeper]# cd /opt/zookeeper/conf
zookeeper]# vi zoo.cfg
# 把下面的三行都删掉，不需要组成集群，如图
~~~

zookeeper]# ps aux|grep zoo
zookeeper]# bin/zkServer.sh status

#### 报错信息

> flannel重启报错问题

~~~
# flannel重启需要增加以下内容，添加在最下面:
21 ~]# vi /etc/sipervisord.d/flannel.ini
killasgroup=true
stopasgroup=true
~~~

#### 如何排错：

~~~
# 查看时间是否正常
date

# 查看kubernetes的报错
21 ~]# tail -fn 200/data/logs/kubernetes/kube-kubelet/kubelet.stdout.log

# 可以重启docker 和 kubelet
21 ~]# systemctl restart docker 
21 ~]# ps aux|grep kubelet
21 ~]# kill -9 id

# 查看supervisor的状态
21 ~]# supervisorctl status

# 查看路由状态，是否能ping通其它机器
21 ~]# route -n
21 ~]# ping 172.7.22.2

# 查看flannel情况
21 ~]# tail -fn 200 /data/logs/flanneld/flanneld.stdout.log
# 12flannel主机器上get网络，如果error则加入backend
12 ~]# ./etcdctl get /coreos.com/network/config

# 报错iptables，让机器一重启就自动使用，21/22机器
~]# service iptables save
# out: [ok]
~~~

#### cm对象的另一种创建方法（可不做）：

~~~
# 22机器：
cd /opt/kubernetes/server/bin/conf
# 当前目录下要又kubelet.kubeconfig的文件
conf]# kubectl create cm kubelet-cm --from-file=./kubelet.kubeconfig
#out: configmap/kubelet-cm created
~~~

可以在dashoboard的default名称空间下Config Maps看到

随后记得删除

> Client通过推拉结合和ConfigService交互，然后ConfigService去拿ConfigDB里面的配置给Client端返回去。
>
> Portal是Apollo的一个仪表盘，通过调用AdminService去同步修改ConfigDB里面的配置
>
> 先交付ConfigService，然后交付AdminService，最后加portal

### dubbo服务提供者连接Apollo实战

首先我们在git新建一个Apollo分支，以下是操作方法

##### git创建分支并上传代码（或者直接fork我），注意，下图配的是gitlab里面web的，现在你要操作的是自己git的service，因为service没截图，所以我用web的替代

1. 切换身份

~~~
   # 上传项目的文件夹打开，然后cd到附近的新建的apollo文件夹，克隆项目并切换身份：
   $ git http://gitlab.od.com:10000/909336740/dubbo-demo-web.git
   $ cd dubbo-demo-web/
   $ git branch apollo
   $ git checkout apollo
   ~~~

![1583287244483](assets/1583287244483.png)

将Apollo分支的文件全部拉来这个文件夹，选择替换重名文件

![1583287180864](assets/1583287180864.png)

2. 把apollo的代码全部拉过去覆盖，并上传代码

~~~
   $ git add .
   $ git commit -m "apollo commit#1"
   $ git push -u origin apollo
   ~~~

![1583287633875](assets/1583287633875.png)

![1582680560428](assets/1582680560428.png)

完成，当然你可以直接fork我的

![1582680588102](assets/1582680588102.png)

#### 继续主线

在Apollo portal里创建相应两个配置项

![1582680643369](assets/1582680643369.png)

新增配置项，并提交

![1583223092507](assets/1583223092507.png)

![1583223148433](assets/1583223148433.png)

发布

![1583223168662](assets/1583223168662.png)

![1583223190037](assets/1583223190037.png)

我们已经配置好了，然后需要用Jenkins制作镜像

~~~
# 填入对应参数
app_name: dubbo-demo-service
image_name: app/dubbo-demo-service
git_repo: https://gitee.com/benjas/dubbo-demo-service.git
git_ver: apollo
add_tag: 200303_1615
target_dir: ./dubbo-server/target
base_image: base/jre8:8u112
~~~

> 注意，我这里用的是gitlab，因为网络问题，你用自己的公网git即可

![1583223413973](assets/1583223413973.png)

去#38的console里查看情况

![1583223612917](assets/1583223612917.png)

#### 报错问题：

![1581324514061](assets/1581324514061.png)

该报错的原因是mirrors没有改对

~~~
# 200机器：
cd /data/nfs-volume/jenkins_home/maven-3.6.1-8u232/conf
conf]# vi settings.xml
~~~

修改完上面的内容后保存再去重新构建

#### 继续主线

![1583223754285](assets/1583223754285.png)

镜像制作完成

~~~
# 200机器，修改指定的镜像，并添加部分内容：
cd /data/k8s-yaml/dubbo-demo-service/
dubbo-demo-service]# vi dp.yaml
        image: harbor.od.com/app/dubbo-demo-service:apollo_200303_1615
        ports:
        - containerPort: 20880
          protocol: TCP
        env:

        - name: C_OPTS
          value: -Denv=dev -Dapollo.meta=http://config.od.com
        imagePullPolicy: IfNotPresent
~~~

~~~
# 22机器，应用：
~]# kubectl apply -f http://k8s-yaml.od.com/dubbo-demo-service/dp.yaml
# out: deployment.extensions/dubbo-demo-service configured
~~~

![1583224029500](assets/1583224029500.png)

去LOGS查看，可以看到连接了Apollo

![1583227298634](assets/1583227298634.png)

> PS：这里的pod名字你可能觉得不一样，因为我镜像弄错了，重新改了一遍

![1583227711909](assets/1583227711909.png)

当你把service扩容成两个后

![1583227780562](assets/1583227780562.png)

可以看到变成两个实例

![1583227821344](assets/1583227821344.png)

在monitor里可以看到端口是20880（注意必须连接的是zk1，怎么修改上面有，先改cm，然后删掉pod让它自动重启）

![1583229093925](assets/1583229093925.png)

![1583229141970](assets/1583229141970.png)

我们去Apollo改一下端口，改成20881，并发布

![1583229265526](assets/1583229265526.png)

![1583229275645](assets/1583229275645.png)

重启两个service的pods（就是删掉让它们自动重启）

![1583229312442](assets/1583229312442.png)

刷新dubbo-monitor，可以看到端口已经变成20881

![1583229337601](assets/1583229337601.png)

还可以改成zk2

![1583229498782](assets/1583229498782.png)

> 作业：改成zk2后，需要删掉对应的pod，然后让其也在zk2，然后还需要把monitor也改成zk2，方法在上面有。这个作业一定要做，不然下面会报错，具体是哪里报错我会提示

最后我改回来了20880端口，但是依然用的zk2

完成

### dubbo服务消费者连接Apollo实战

~~~

关闭deployment里的消费者和服务者（改成scale 0，先消费者后服务者）

[^关于http://apollo-configservice:8080]: 直接用这个和用http://config-test.od.com是没有区别的，http://config-test.od.com是多了一层反代，而apollo-configservice:8080是因为它们在同一名称空间里，所以可以这么使用
