**Docker + SpringBoot + Maven 构建发布到远程仓库**  
*环境：Aliyun Centos 7 Windows10 IDEA Maven3.5.4*

1.  Docker安装:  
      
    [参考阿里云的安装手册][Link 1]  
    
    
    1.1 **CentOS 7 (使用yum进行安装)**
    
        # step 1: 安装必要的一些系统工具
        sudo yum install -y yum-utils device-mapper-persistent-data lvm2
        # Step 2: 添加软件源信息
        sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
        # Step 3: 更新并安装 Docker-CE
        sudo yum makecache fast
        sudo yum -y install docker-ce
        # Step 4: 开启Docker服务
        sudo service docker start
        
        # 注意：
        # 官方软件源默认启用了最新的软件，您可以通过编辑软件源的方式获取各个版本的软件包。例如官方并没有将测试版本的软件源置为可用，你可以通过以下方式开启。同理可以开启各种测试版本等。
        # vim /etc/yum.repos.d/docker-ce.repo
        #   将 [docker-ce-test] 下方的 enabled=0 修改为 enabled=1
        #
        # 安装指定版本的Docker-CE:
        # Step 1: 查找Docker-CE的版本:
        # yum list docker-ce.x86_64 --showduplicates | sort -r
        #   Loading mirror speeds from cached hostfile
        #   Loaded plugins: branch, fastestmirror, langpacks
        #   docker-ce.x86_64            17.03.1.ce-1.el7.centos            docker-ce-stable
        #   docker-ce.x86_64            17.03.1.ce-1.el7.centos            @docker-ce-stable
        #   docker-ce.x86_64            17.03.0.ce-1.el7.centos            docker-ce-stable
        #   Available Packages
        # Step2 : 安装指定版本的Docker-CE: (VERSION 例如上面的 17.03.0.ce.1-1.el7.centos)
        # sudo yum -y install docker-ce-[VERSION]
    
    1.2 安装校验，输入如下命令，会显示docker信息  
      
    `docker version`
2.  Docker私服仓库搭建(无登录密码)  
      
    *环境：PSW(Private service warehouse私服仓库)，使用registry V2方式安装，[域名假设域名使用reg.winner.com][reg.winner.com]*

2.1 host域名映射：echo ‘192.168.206.210 [reg.winner.com][reg.winner.com 1]’>> /etc/hosts

2.2 环境准备-https证书(openssl证书生成，可能需要安装openssl):  
  
Key:

mkdir -p ~/certs
     cd ~/certs
     openssl genrsa -out reg.winner.com.key 2048

Crt文件：

openssl req -newkey rsa:4096 -nodes -sha256 -keyout reg.winner.com.key -x509 -days 365 -out reg.winner.com.crt

一些要填的信息:

Country Name (2 letter code) [XX]:CN
     # 国家
     State or Province Name (full name) []:JS
     # 省会
     Locality Name (eg, city) [Default City]:NJ
     # 城市
     Organization Name (eg, company) [Default Company Ltd]:ITMUCH
     # 组织(公司)
     Organizational Unit Name (eg, section) []:ITMUCH
     # 组织单位(部门)
     Common Name (eg, your name or your server's hostname) []:reg.winner.com 
     # 域名
     Email Address []:eacdy0000@126.com
     # 邮件

Tips:自签名证书不受docker信任,需要添加到Docker根证书中,Centos 7的存放路径：\`\`\`/etc/docker/certs.d/域名\`\`

mkdir -p /etc/docker/certs.d/reg.winner.com
    cp ~/certs/reg.winner.com.crt /etc/docker/certs.d/reg.winner.com/

重启docker: `service docker restart`

2.3 私服仓库的启动：

`cd ~`

docker run -d -p 443:5000 --restart=always --name registry -v `pwd`/certs:/certs -v /opt/docker-image:/opt/docker-image -e STORAGE_PATH=/opt/docker-image -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/reg.winner.com.crt -e REGISTRY_HTTP_TLS_KEY=/certs/reg.winner.com.key registry:2

一些参数解释：
        `pwd`/certs:/certs --- 将当前目录(cd ~)下的certs挂载到容器的certs目录
        -v /opt/docker-image:/opt/docker-image --指定存储镜像路径，防止私有仓库容器被删，镜像也丢失
        -e REGISTRY_HTTP_TLS_CERTIFICATE和-e REGISTRY_HTTP_TLS_KEY 指定证书路径

2.4 开放远程API，以供我们IDEA+MAVEN远程push镜像到私服仓库:  
  
1). docker默认是没有开启Remote API的，需要我们手动开启  
编辑`/lib/systemd/system/docker.service`文件。*(tips:该文件路径不一定在这里，本案例是在这个目录)*  
  
修改如下内容：

[Service]
     Type=notify
     # the default is not to use systemd for cgroups because the delegate issues still
     # exists and systemd currently does not support the cgroup feature set required
     # for containers run by docker
     ExecStart=/usr/bin/dockerd -H unix:///var/run/docker.sock -H tcp://0.0.0.0:2375
     #ExecStart=/usr/bin/dockerd -H fd://
     #ExecStart=/usr/bin/dockerd -H unix://
     ExecReload=/bin/kill -s HUP $MAINPID

重点关注:`ExecStart`这个参数  
  
2). 重启服务  
  
`sudo systemctl daemon-reload`  
  
`sudo service docker restart`  
  
3). 验证  
  
浏览器输入`192.168.206.210:2375/images/json`能返回宿主机的所有信息，如镜像信息：

[{"Containers":-1,"Created":1548890077,"Id":"sha256:d0eed8dad114db55d81c870efb8c148026da4a0f61dc7710c053da55f9604849","Labels":null,"ParentId":"","RepoDigests":["registry@sha256:870474507964d8e7d8c3b53bcfa738e3356d2747a42adad26d0d81ef4479eb1b"],"RepoTags":["registry:2"],"SharedSize":-1,"Size":25779681,"VirtualSize":25779681}]

3.1 windwos环境添加`DOCKER_HOST`环境变量:

DOCKER_HOST
      tcp://192.168.206.210:2375

3.2 pom关键配置配置：

                          <dockerHost>http://192.168.206.210:2375</dockerHost>
                          <resources>
                              <resource>
                                  <directory>${project.build.directory}</directory>
                                  <include>${project.build.finalName}.jar</include>
                              </resource>
                          </resources>
                      </configuration>
                  </plugin>

3.3 Dockerfile配置:

## 基于java 8镜像
      FROM java:8
      
      ## 将本地文件挂在到当前容器
      VOLUME /tmp
      
      ## 拷贝文件内容
      ADD omni-zipkin-server.jar zipkin-server.jar
      RUN bash -c 'touch /zipkin-server.jar'
      
      ## 开放端口
      EXPOSE 8818
      
      ## 容器启动后命令
      ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/zipkin-server.jar"]

3.4 执行maven package 打包 输出信息：
