4.dubbo-api的yml配置文件部分

server:
  port: 20138
spring:
  application:
    name: dubbo-api
#MyBatis-plus的配置部分
mybatis-plus:
  global-config:
    db-config:
      table-prefix: ct_
      id-type: assign_id
  configuration:
    map-underscore-to-camel-case: true
  mapper-locations: classpath*:mapper/*Mapper.xml

5.dubbo-provider的yml文件部分

server:
  port: 20198


#指定Dubbo的配置
dubbo:
  application:
    name: dubbo-provider
  registry:
    protocol: zookeeper
    address: localhost:2181
  protocol:
    name: dubbo
    port: 20880
  scan:
    base-packages: cn.com.dubbo.provider.impl

Linux上安装zookeeper（Linux）

查看docker提供的zookeeper的镜像文件
docker search zookeeper

拉取zookeeper的镜像
docker pull zookeeper

查看docker 的镜像是否拉取成功
docker images 

运行docker镜像
docker run --privileged=true -d --name zookeeper --publish 12181:2181 -d zookeeper:latest

查看镜像是否运行成功
docker ps (能看见zookpper的名字表示镜像启动成功)

ps:如果想进入到zookeeper的容器中
docker exec -it zk容器ID /bin/bash

ls:查看容器里面的目录

cd bin/ :进入到容器的bin目录中

./zkCli.sh :进入到zookeeper的客户端

ls / 查看全部的节点
quit :退出zk客户端

exit退出docker容器

这样zookeeper的安装就完成了

下边来说下如何能直观的看到dubbo的服务注册结果(安装dubbo-admin客户端)

这边提供一个dubbo-admin的下载地址网上也有很多这边是我自己用的:

链接：https://pan.baidu.com/s/1C_S-0uLt3FzBPT0Zvh5fxA 
提取码：b62o

接下来说下dubbo-admin的客户端如何使用

ps:首选端口可以选择性修改,其次是zookeeper的服务地址要改成知己的端口地址,然后登录的用户密码可以选择修改root用户密码是root,guest用户密码是guest这边为了方便我统一修改为root

然后我们将该文件打一个包这边可以看下pom我们这边打的是jar包

运行命令
mvn clean package

能看多啊SUCCESS说明打包成功

ps:当然想吧java程序跑起来肯定是需要用到jdk的所以们可以选择在docker中安装一个JDK(docker安装JDK请自行百度谢谢)

想要将jar包变成可运行的docker容器咋办呢这边我们来编写一个Dockerfile

1.我们在linux中创建一个文件夹用来存放jar包和Dockerfile文件

cd /usr
mkdir jar_file
将jar包上传到jar_file文件中
cd jar_file/
vim Dockerfile

这边我们编写个Dockerfile文件试试#指定JDK的版本

FROM java:8

#创建人信息
MAINTAINER LingZsj

#这里的 /tmp 目录就会在运行时自动挂载为匿名卷，任何向 /tmp 中写入的信息都不会记录进容器存储层。
VOLUME /tmp

#添加文件中的dubbo-admin-0.0.1-SNAPSHOT.jar到docker容器中
ADD dubbo-admin-0.0.1-SNAPSHOT.jar dubbo-admin.jar

#bash方式执行,使得ct-plat.jar可访问
#RUN新建立一层,在其上执行这些命令,执行结束后.commit这层修改,构成新镜像
RUN bash -c "touch /dubbo-admin.jar"

#申明服务运行时容器提供服务端口,只做申明,并不会主动开启服务端口
EXPOSE 17001

#指定容器启动程序及参数
ENTRYPOINT ["java","-jar","dubbo-admin.ja"]



....好像写不下了感觉是不是我写的太啰嗦了...只能在这里追加了抱歉~QvQ~
然后在jar_file文件夹目录中运行
docker build -t dubbo-admin .

　ps:后面的.别写掉了
 
然后docker images查看镜像时候构建成功
如成功了name我们就来启动容器了

docker run -d --name dubbo-admin -p 17001:17001 dubbo-admin
这边-p前面的端口是容器与外部映射的端口也就是你外部访问的端口:后面的端口是你application.properties中配置的程序的端口别写错了...


好了写完了写完了溜了溜了,若有错误欢迎指教谢谢^V^
