## 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
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
~~~
~~~
# 11/12机器，启动zk：
cd /opt/zookeeper/
zookeeper]# bin/zkServer.sh start
zookeeper]# ps aux|grep zoo
zookeeper]# bin/zkServer.sh status
~~~
Mode: standalone 模式，拆分完成
~~~
# 200机器，准备资源配置清单：
~]# vi /data/k8s-yaml/dubbo-monitor/cm.yaml

# 对比两个dp有什么不同，200机器：
cd /data/k8s-yaml/dubbo-monitor/
dubbo-monitor]# vimdiff dp.yaml dp2.yaml
#:qall 退出
~~~
> **vimdiff **：编辑同一文件的不同历史版本，对各文件的内容进行比对与调整
>
> 没有vimdiff 的下载 yum install vim -y
> 这里两个文件不同的地方，注意，这里的image的版本因为我的操作问题所以一个v2一个没有v，你的应该是都没有的
~~~
# 200机器，替换dp：
dubbo-monitor]# mv dp.yaml /tmp/
dubbo-monitor]# mv dp2.yaml dp.yaml
~~~
> **mv**：如果mv后是目录，则是移动，如果是文件名，则是更改名字
~~~
# 应用资源配置清单，22机器：
~]# kubectl apply -f http://k8s-yaml.od.com/dubbo-monitor/cm.yaml
~]# kubectl apply -f http://k8s-yaml.od.com/dubbo-monitor/dp.yaml
# 看一下相关容器有没有起来
~~~
我们改成zk2
在删掉这个pod重启
刷新页面变成zk2了
完成
#### 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

#### 官方Apollo框架：
#### 简化Apollo框架：
> 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
