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

1583162339688

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

1581059149533

# 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

1581059640346

# 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

1584697777390

Mode: standalone 模式，拆分完成

# 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

1583198466051

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

1583199496585

在删掉这个pod重启

1583199525277

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

# 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

官方Apollo框架：

WHAT：请参考官方总体设计，Apollo框架的特性也已经在上面跟Spring Cloud做了对比。更多的解释可以参考官方特性文档

WHY：用该框架实现比Spring Cloud更优的能力，更多对比可参考Nacos、Apollo、Spring Cloud Config微服务配置中心对比

1587274472834

简化Apollo框架：

WHY：

参考官方微服务架构使用Apollo架构V1

Meta Server：

  • Portal通过域名访问MetaServer获取AdminService的地址列表
  • Client通过域名访问MetaServer获取ConfigService的地址列表
  • 相当于一个Eureka Proxy
  • 逻辑角色，和ConfigService住在一起部署

Eureka：

  • 用于服务发现和注册
  • Config/AdminService注册实例并定期报心跳
  • 和ConfigService住在一起部署

可以看到Eureka和Zookeeper是一样的功能，所以不再搭建重复的功能服务。

而为什么使用Zookeeper，总得来说Eureka基于AP保证高可用，遇到问题，时可以牺牲其一致性来保证系统服务的高可用性，既返回旧数据。Zookeeper基于CP，追求数据一致性。实际业务使用什么要基于业务考量。

1584698746125

1584698613252

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

1583222393771

完成

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

建议直接使用公网的 https://gitee.com/benjas/dubbo-demo-service.git 或者拷贝一份

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

    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

  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

    1582680560428

    完成，当然你可以直接fork我的

    1582680588102

继续主线

建议直接使用公网的 https://gitee.com/benjas/dubbo-demo-service.git 或者拷贝一份

在Apollo portal里创建相应两个配置项（注意看清位置，是 ：resources 下的）

1582680643369

新增配置项，并提交

1583223092507

1583223148433

发布

1583223168662

1583223190037

我们已经配置好了，然后需要用Jenkins制作镜像

建议直接使用公网的 https://gitee.com/benjas/dubbo-demo-service.git 或者拷贝一份

# 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

去#38的console里查看情况

1583223612917

报错问题：

1581324514061

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

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

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

1583223916007

# 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

去LOGS查看，可以看到连接了Apollo

1583227298634

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

当你把service扩容成两个后

1583227780562

可以看到变成两个实例

1583227821344

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

1583229141970

我们去Apollo改一下端口，改成20881，并发布

1583229265526

1583229275645

重启两个service的pods（就是删掉让它们自动重启）

1583229312442

刷新dubbo-monitor，可以看到端口已经变成20881

1583229337601

还可以改成zk2

1583229498782

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

同样，我是有Apollo分支的，操作方法和上面的service服务一样

1583289334584

用Jenkins构建dubbo消费者

再去Applications可以看到已经起来了

# 浏览器访问demo.od.com/hello?name=apollo

1583291263893

如果你登录的是这个界面，那么你没有做作业：改service的zk1成zk2，这个consumer已经是zk2的，而service还是zk1，当然不能响应

实战Apollo分环境管理dubbo服务-交付Apollo-configservice

我们要实现测试环境和生产环境只需要打包一个镜像

先开始分环境

# 11机器，解析域名：
~]# vi /var/named/od.com.zone
serial 前滚一位
zk-test            A    10.4.7.11
zk-prod            A    10.4.7.12

~]# systemctl restart named
~]# dig -t A zk-test.od.com +short
# out: 10.4.7.11
~]# dig -t A zk-prod.od.com +short
# out: 10.4.7.12

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

1583301119606

# 创建两个名称空间， 21机器：
~]# kubectl create ns test
# out:namespace/test created
~]# kubectl create secret docker-registry harbor --docker-server=harbor.od.com --docker-username=admin --docker-password=Harbor12345 -n test
# out:secret/harbor created
~]# kubectl create ns prod
# out:namespace/prod created
~]# kubectl create secret docker-registry harbor --docker-server=harbor.od.com --docker-username=admin --docker-password=Harbor12345 -n prod
# out:secret/harbor created

1583301237979

去看一下dashboard里面的Namespaces

1583301259487

把admin、portal、config都scale成0

1583301320962

# 11机器，建库：
~]# vi apolloconfig.sql
# 增加Test关键字

1583301385286

# 11机器，测试环境：

1583301481115

# 11机器，修改支持类型：

ApolloPortalDB]> show tables;
ApolloPortalDB]> select * from ServerConfig\G
ApolloPortalDB]> update ServerConfig set Value='fat,pro' where Id=1;
ApolloPortalDB]> select * from Serverconfig\G

改后

1583302030474

PS按理来说你应该只有dev，但是好像Apollo更新了，一开始就有4种支持的类型，只要你确保有fat和pro即可

# 200机器：
cd /data/k8s-yaml/apollo-portal/
# 需改以下内容
apollo-portal]# vi cm.yaml
  apollo-env.properties: |
    fat.meta=http://config-test.od.com
    pro.meta=http://config-prod.od.com

1583302159311

# 22机器，应用：
~]# kubectl apply -f http://k8s-yaml.od.com/apollo-portal/cm.yaml
# out: configmap/apollo-portal configured

1583302232037

完成

实战使用Apollo分环境管理dubbo服务——交付Apollo-portal和adminservice

确认你的nslookup.exe 有没有（一般是有的）

1581347525407

# 访问config-test.od.com
config.od.com已经没了

1583304944456

# 访问config-prod.od.com
prod可能还没好，接着往下面做，test能起来，prod肯定也能起来

1583304959338

可以看到test和prod在两个不同的容器里，这就是我们模拟的分环境
