ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

插件配置

插件地址 ：https://github.com/spotify/dockerfile-maven
增加属性

    <properties>
        <java.version>1.8</java.version>
        <docker.registry.url>registry.cn-beijing.aliyuncs.com</docker.registry.url>
        <docker.registry.namespace>baxiang</docker.registry.namespace>
    </properties>

增加插件配置

<plugin>
                <groupId>com.spotify</groupId>
                <artifactId>dockerfile-maven-plugin</artifactId>
                <version>1.4.13</version>
                <executions>
                    <execution>
                        <id>default</id>
                        <goals>
                            <goal>build</goal>
                            <goal>push</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <tag>${project.version}</tag>
                    <buildArgs>
                        <JAR_FILE>${project.build.finalName}.jar</JAR_FILE>
                    </buildArgs>
                    <repository>${docker.registry.url}/${docker.registry.namespace}/${project.artifactId}</repository>
                    <useMavenSettingsForAuth>true</useMavenSettingsForAuth>
                </configuration>
            </plugin>

配置maven

参考 https://github.com/spotify/dockerfile-maven/blob/master/docs/authentication.md
隐藏 POM 文件中的密码
maven 提供密码加密的功能，具体过程见：https://maven.apache.org/guides/mini/guide-encryption.html
配置完 ~/.m2/setting-security.xml 后，在 ~/.m2/setting.xml 找到 servers 标签，添加：

<servers>
    <server>
        <id>registry.cn-shanghai.aliyuncs.com</id>
        <username>userName</username>
        <password>{encryptedPassword}</password>
    </server>
</servers>

修改 POM 文件中的配置即可

<configuration>
    <repository>registry.cn-shanghai.aliyuncs.com/xxxxx/xxxxx</repository>
-   <username>userName</username>
-   <password>userPassword</password>
+   <useMavenSettingsForAuth>true</useMavenSettingsForAuth>
    <buildArgs>
        <JAR_FILE>${project.build.finalName}.jar</JAR_FILE>
    </buildArgs>
</configuration>

或者使用

<useMavenSettingsForAuth>true</useMavenSettingsForAuth>

修改maven中的conf/settings.xml文件,找到节点，在里面添加阿里云的server节点

    <server>
      <!--maven的pom中可以根据这个id找到这个server节点的配置,配置成dockerhub 的URL地址-->  
      <id>registry.cn-beijing.aliyuncs.com</id>
      <!--这里是在阿里云注册的账号-->
      <username>xxxx@xxx.com</username>
      <!--这里是在阿里云注册的密码-->
      <password>xxxx</password>
    </server>

打包命令

打tag命令

mvn package dockerfile:build

推送远程

mvn dockerfile:push

问题排查 增加-X 参数

mvn clean package docker:build -X

IDEA插件

搜索插件Docker

设置中搜索Docker

修改docker p配置

sudo vim /lib/systemd/system/docker.service

修改

增加

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

重启docker

sudo systemctl restart docker

查看2375端口是否开发

netstat -nlp|grep 2375
tcp6       0      0 :::2375                 :::*                    LISTEN      14626/dockerd

设置连接

增加仓库
