   1. 在M1芯片中构建

在构建时一同构建docker镜像及推送

定义Pom

在pom的description节点中引入properties定义推送的镜像仓库

<properties>
    <java.version>1.8</java.version>
    <docker.repostory>registry.cn-hangzhou.aliyuncs.com/bohai_repo</docker.repostory>
</properties>

build节点中引入插件：dockerfile-maven-plugin

<plugin>
    <groupId>com.spotify</groupId>
    <artifactId>dockerfile-maven-plugin</artifactId>
    <version>1.4.10</version>
    <executions>
        <execution>
            <id>default</id>
            <goals>
                <goal>build</goal>
                <goal>push</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <repository>${docker.repostory}/${project.artifactId}</repository>
        <!--  镜像tag取用project.version -->
        <tag>${project.version}</tag>
        <buildArgs>
            <!--  在target目录中查找project.build.finalName节点下的jar包 -->
            <JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE>
        </buildArgs>
    </configuration>
</plugin>

新建一个dockerfile

FROM openjdk:8u191-jre-alpine3.9
ENTRYPOINT ["/usr/bin/java", "-jar", "/app.jar"]
# 在pom中定义的 标签
ARG JAR_FILE
ADD ${JAR_FILE} /app.jar
EXPOSE 8080

构建

# 只构建
$ mvn install dockerfile:build

# 构建+ 推送
$ mvn install dockerfile:push

在M1芯片中构建

$ brew install socat
$ nohup socat TCP-LISTEN:2375,range=127.0.0.1/32,reuseaddr,fork UNIX-CLIENT:/var/run/docker.sock &> /dev/null &
$ export DOCKER_HOST=tcp://127.0.0.1:2375
