站长资讯网先来架构，如图：
1.前端出口服务为阿里SLB
2.Zookeeper集群为整个微服务环境提供注册中心，Zookeeper集群每个znode的IP固定，也同样由config-service服务配置。
3.集中配置服务config-service，由git集中管理配置文件，config-service配置映射宿主机某个目录。配置如需修改直接Git中修改，触发宿主机映射的目录中进行git pull操作，然后重启对应的provider，配置即可生效。
4.facade作为分发器做分发服务。
微服务工作流程：
1)provider启动，读取写死的config-service配置服务，从配置服务中获取到Zookeeper地址，进行注册。
2)请求由阿里SLB分发至对应微服务facade，网关前往Zookeeper集群注册中心获取可用服务。
3)获取到可用provider后，facade进行分发请求，策略为轮询。
4)如后端provider挂了，无法提供服务，Zookeeper会自动剔除该服务的注册。
建立微服务基础运行环境，gateway网关、Zookeeper注册中心、config-service配置基础运行环境。开始构建以上基础运行环境：
一、创建zookeeper3.4.10集群服务
需包含了jdk和配置好环境变量的镜像，jdk1.8镜像。
jdk1.8镜像交付到阿里云Docker Registry仓库
Docker Rancher宿主机
1.下载jdk1.8.0_25.tar包，自行下载。

4.登录阿里云容器镜像服务
创建镜像仓库名称ms-jdk1.8
5.镜像push到阿里云Docker Registry
切换到rancher/server
登录到阿里云Docker Registry
登录Docker Registry -> 打tag -> push到Docker Registry

至此，ms-jdk1.8镜像交付完成。
zookeeper3.4.10集群创建，并将Zookeeper3.4.10镜像交付到阿里云Docker Registry仓库。
1.zookeeper3.4.10集群构建前提准备：
zookeeper3.4.10集群需其配置文件中指定各个选举节点的ip和端口，并且zookeeper集群中的datadir（zoo.cfg配置中：dataDir=/tmp/zookeeper）中，需指定节点的myid，才能完成Zookeeper集群搭建。在不使用docker link功能前提下，容器化Zookeeper集群，需要解决：
1).myid问题。
2).Zookeeper集群节点（leader、follower）选举配置。
可使用docker内置的volume功能，将配置文件和Zookeeper的datadir映射至宿主机进行管理。
如在rancher中：
所以，宿主机必须存在：
1) zookeeper-config/，目录为Zookeeper所有配置文件，包含集群的选举节点IP和选举端口，主要zoo.cfg文件中。
ll zookeeper-config/ total 16 -rw-r--r-- 1 root root 535 Jan 4 17:43 configuration.xsl -rw-r--r-- 1 root root 2161 Jan 4 17:43 log4j.properties -rw-r--r-- 1 root root 1012 Jan 4 17:43 zoo.cfg -rw-r--r-- 1 root root 922 Jan 4 17:43 zoo_sample.cf2) zookeeper-data01/，目录对应zookeeper集群中的datadir，有存放一个myid文件，Zookeeper集群启动后产生的数据也会持久化到此宿主机目录下。Zookeeper集群有3个znode节点，所以datadir有：
zookeeper-data02/
zookeeper-data03/
ll /data/docker/ drwxr-xr-x 3 root root 48 Jan 5 17:25 ms-zookeeper3.4.10 drwxr-xr-x 2 root root 92 Jan 5 16:54 zookeeper-config drwxr-xr-x 2 root root 18 Jan 4 17:59 zookeeper-data01 drwxr-xr-x 2 root root 18 Jan 4 18:02 zookeeper-data02 drwxr-xr-x 2 root root 18 Jan 4 18:02 zookeeper-data032.镜像构建
2.1 下载zookeeper-3.4.10.tar.gz包
wget https://mirrors.cnnic.cn/apache/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz
创建zookeeper-3.4.10构建build目录
mkdir -p /data/docker/ms-zookeeper3.4.10/ -rw-r--r-- 1 root root 207 Jan 4 18:58 dockerfile drwxr-xr-x 10 root root 4096 Mar 23 2017 zookeeper-3.4.102.2 编写dockfile
vim /data/docker/ms-zookeeper3.4.10/dockerfile
FROM ms/jdk1.8:v1 MAINTAINER zookeeper3.4.10 "name@alaxiaoyou.com" ADD zookeeper-3.4.10/ /usr/local/zookeeper/ WORKDIR /usr/local/zookeeper ENTRYPOINT ./bin/zkServer.sh start && tail -f zookeeper.out其中zookeeper-3.4.10目录添加至镜像中，然后交付。但只是一个Zookeeper运行的模板，具体配置可通过volume，用宿主机的配置覆盖镜像中的配置。
2.3 构建，镜像
cd /data/docker/ms-zookeeper3.4.10 docker build -t ms/zookeeper3.4.10:v1 . docker images | grep zook ms/zookeeper3.4.10 v1 cb1bea8cf3d5 23 hours ago 567MB registry.cn-hangzhou.aliyuncs.com/xmbaby-tmp/tmp-zookeeper-ms v1 cb1bea8cf3d5 23 hours ago 567MB镜像运行，本地docker本身命令行启动Zookeeper容器
[root@rancher-qa docker]# docker run --name zookeeper01 -it -v /data/docker/zookeeper-config/:/usr/local/zookeeper/conf/ -v /data/docker/zookeeper-data01/:/tmp/zookeeper/ ms/zookeeper3.4.10 /bin/bash以上docker命令行启动卷映射目录正常，宿主机目录能映射到容器中。但rancher中用UI界面进行卷映射时，发现宿主机映射的目录在容器中并未映射到。待解决。
此问题是由于，rancher有两台主机，而容器都运行在未进行设置映射目录的宿主机中。此问题困扰近一周时间，<_>
2.4 登录阿里云容器镜像服务
创建镜像仓库名称tmp-zookeeper-ms
2.5 zookeeper镜像push到阿里云Docker Registry
切换到rancher/server
登录到阿里云Docker Registry
登录Docker Registry -> 打tag -> push到Docker Registry
[root@rancher-qa ms-zookeeper3.4.10]# docker login --username=name@alaxiaoyou.com registry.cn-hangzhou.aliyuncs.com Password: Login Succeeded [root@rancher-qa ms-zookeeper3.4.10]# [root@rancher-qa ms-zookeeper3.4.10]# docker tag cb1bea8cf3d5 registry.cn-hangzhou.aliyuncs.com/xmbaby-tmp/tmp-zookeeper-ms:v1 [root@rancher-qa ms-zookeeper3.4.10]# [root@rancher-qa ms-zookeeper3.4.10]# docker push registry.cn-hangzhou.aliyuncs.com/xmbaby-tmp/tmp-zookeeper-ms:v1 The push refers to a repository [registry.cn-hangzhou.aliyuncs.com/xmbaby-tmp/tmp-zookeeper-ms] ed1b06ecb437: Pushed 96f6833b8de8: Mounted from xmbaby-tmp/ms-jdk1.8 071d8bd76517: Mounted from xmbaby-tmp/ms-jdk1.8 v1: digest: sha256:c55b36fb410d7db9409e3ca4fb27e0d8d2d05e1970d99270ff9d5a6d8ee25e0b size: 954 [root@rancher-qa ms-zookeeper3.4.10]# docker images | grep zook registry.cn-hangzhou.aliyuncs.com/xmbaby-tmp/tmp-zookeeper-ms latest cb1bea8cf3d5 8 days ago 567MB registry.cn-hangzhou.aliyuncs.com/xmbaby-tmp/tmp-zookeeper-ms v1 cb1bea8cf3d5 8 days ago 567MB ms/zookeeper3.4.10 latest cb1bea8cf3d5 8 days ago 567MB ms/zookeeper3.4.10 v1 cb1bea8cf3d5 8 days ago 567MB2.6查看
至此，tmp-zookeeper-ms镜像交付完成。
3.这里选择rancher来做docker集群的管理和编排，除了使用docker本身命令行界面启动Zookeeper容器外，推荐使用rancher UI界面进行容器管理和创建。
在rancher中，添加zk1、zk2、zk3容器服务：
创建zk1：
卷管理：
设置容器主机：
另两个znode节点，zk2、zk3同理操作，只是路径和名称做稍微改动。
进入Zookeeper容器中查看启动信息，查看Zookeeper机器znode2为集群leader：
二、创建config-service服务
集中配置服务config-service，作为公司微服务基础运行环境部分，需要优先单独创建。
为做好后期集中打包，使用maven工具，需先创建一maven镜像，该maven镜像集成了公司自己nexus服务，任何开发都可通过此镜像进行快速打包本地的开发环境的jar包。
Docker Rancher宿主机
1.下载apache-maven-3.3.9-bin.tar.gz包，自行下载。

- tmp-config-service-ms镜像启动，统一用rancher编排UI工具来启动。
tmp-config-service-ms服务启动需依赖宿主机的目录，这个目录，是本地git仓库项目，gitlab中为：git@xxxx.git。provider配置修改，都通过gitlab进行修改，会进行更新到本地目录中，重启此provider即可生效。
2.1 启动tmp-config-service-ms服务，rancher中操作。
创建服务tmp-config-service-ms：
设置卷：
设置容器主机名：
2.2 启动tmp-config-service-ms容器服务。此provider只在启动初，会找一次config-service，但此config-service服务为单点服务。不过，容器可快速销毁和生成的特性，即使此config-service配置服务出现问题，也可立即自动重启或手工销毁有问题的容器，并重新生成新的config-service服务容器，此过程为秒级，是可接受配置服务为单点。
进入config-service服务容器，查看启动情况，日志查看：
三、创建gateway-service服务
网关gateway-service服务是整个微服务架构的入口，在构建provider前，必须建立先创建好网关服务。
git clone网关项目代码，git@xxxx.git
1.创建网关项目目录：
mkdir -p /data/httpd/ms-api-gateway-tmp/alaxiaoyou-api-gateway
[root@rancher-qa ms-api-gateway-tmp]# git clone git@xxxxx.git Cloning into 'alaxiaoyou-api-gateway'... remote: Counting objects: 1198, done. remote: Compressing objects: 100% (552/552), done. remote: Total 1198 (delta 423), reused 554 (delta 241) Receiving objects: 100% (1198/1198), 108.00 KiB | 0 bytes/s, done.

2.创建网关项目dockerfile
vim /data/httpd/ms-api-gateway-tmp/alaxiaoyou-api-gateway/dockerfile
FROM ms/jdk1.8:v1 MAINTAINER gateway-service "name@alaxiaoyou.com" RUN mkdir /data/httpd/ -p ADD gateway-service/target/alaxiaoyou-api-gateway-0.0.1-SNAPSHOT.jar /data/httpd/ EXPOSE 80 #此处虽然开启了80端口映射，但是并没有做link链接 WORKDIR /data/httpd/ ENTRYPOINT java -jar alaxiaoyou-api-gateway-0.0.1-SNAPSHOT.jar说明：ENTRYPOINT进入容器中执行此jar包。

至此，gateway-service-ms镜像交付完成。
用rancher编排UI工具来���动gateway-service：
1.进入rancher应用栈添加服务。因为网关gateway服务需映射80端口至宿主机，因此，创建容器选择“总是在每台主机上运行一个此容器的实例”。映射80端口。添加关联的目标服务。
网关服务gateway-service启动会连接关联的目标服务config-service，config-service是通过git管理的config配置项目来获取配置信息给网关服务。关联Zookeeper集群注册服务。
2.自动重启选择“从不(仅启动一次)”：
3.对于网关服务，可使用docker本身来管理内存分配，可进行动态调整：
4.进入容器查看gateway-service服务启动。
自此，网关服务gateway-service添加完成。
