SpringCloud 实战｜10.SpringCloud 实现docker 镜像部署-提升项目的生产力

本地仓库配置安装本地仓库

docker run -itd -v /home/registry:/var/lib/registry -p 5000:5000 --restart=always --privileged=true --name registry registry:latest

配置私有仓库

vim /etc/docker/daemon.json
{
  "insecure-registries": ["192.168.64.6:5000"]
}
systemctl daemon-reload
systemctl restart docker

http://192.168.64.6:5000/v2/_catalog

开启docker 远程连接

vim /lib/systemd/system/docker.service

# 修改ExecStart为：
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock -H 0.0.0.0:2375

配置项目定义变量

在父级项目的pom->properties 添加如下配置
docker.host：docker安装的主机ip
docker.registry.repository：上面搭建的本地仓库主机ip+端口号
docker.maven.plugin.version：插件版本

  http://192.168.64.2:2375
  192.168.64.2:5000
  1.0.0

添加编译插件

在父级项目的pom->build->pluginManagement->plugins添加如下配置

     
                    com.spotify
                    docker-maven-plugin
                    ${docker.maven.plugin.version}
                    
                        
                            build-image
                            package
                            
                                build
                                push
                            
                        
                    
                    
                        ${docker.registry.repository}/${project.artifactId}:${project.version}
                        ${docker.host}
                        java:8
                        ["java", "-jar","-Dspring.profiles.active=prod","/${project.build.finalName}.jar"]
                        
                        
                            
                                /
                                ${project.build.directory}
                                ${project.build.finalName}.jar

添加打包方式到每个子模块中

将以下加入到每个子模块的pom中

    
        
            
                org.springframework.boot
                spring-boot-maven-plugin
            
            
                com.spotify
                docker-maven-plugin

打包验证

1.执行package
2.完成推送
3.打开浏览器访问 ttp://192.168.64.6:5000/v2/_catalog
4.如果返回了我们项目的镜像，则说明docker打包成功
5.在docker 主机上执行命令 docker run 192.168.64.2:5000/ams-gateway(以网关作为验证)
6.如果执行成功，说明镜像有效

docker 常见错误解决错误1

rquest to {}->unix://localhost:80: No such file or directory
解决方案：
1.确认imageName 是否包含仓库地址(需要包含)
