產生錯誤的pom.xml:

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
             <plugin>

                <artifactId>docker-maven-plugin</artifactId>

                <configuration>
                <imageName>${docker.image.prefix}/${project.artifactId}

                        </resource>
                    </resources>
                </configuration>
            </plugin>
        </plugins>
    </build>
錯誤的原因

1.<imageName>${docker.image.prefix}/${project.artifactId}</imageName>

imagename中字母必須全部小寫,我的${project.artifactId}中含有大寫字母

2.  <dockerDirectory>/src/main/docker</dockerDirectory>


 路徑改為${project.basedir}/src/main/docker

更改之後的pom.xml

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
             <plugin>
                <groupId>com.spotify</groupId>
                <artifactId>docker-maven-plugin</artifactId>
                <version>0.4.3</version>
                <configuration>
                <imageName>luo/ec</imageName>
                    <dockerDirectory>${project.basedir}/src/main/docker</dockerDirectory>
                    <resources>
                        <resource>
                            <targetPath>/</targetPath>
                <directory>${project.build.directory}</directory>
                            <include>${project.build.finalName}.jar</include>
                        </resource>
                    </resources>
                </configuration>
            </plugin>
        </plugins>
    </build>
最後構建成功

注意:

1.在專案的/src/main下建立一個docker目錄,在docker目錄下建立Dockerfile檔案

2 Dockerfile

FROM frolvlad/alpine-oraclejdk8:slim
VOLUME /tmp
ADD ./EurekaClient-0.0.1-SNAPSHOT.jar app.jar
#RUN bash -c 'touch /app.jar'
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
EXPOSE 8761

ADD 指令後面的第一個路徑是jar相對於/target/docker/Dockerfile的路徑  第二個是容器中的路徑
