无法使用 docker 运行 Spring Boot 应用程序

Question

以下场景：场景： 我在 Eclipse 上使用 Spring Boot 2 开发了一个微服务应用程序。该应用程序工作正常。现在我想用 docker 运行它。此外，图像必须与 mysql 数据库交互。为了构建 docker 镜像，我在 pom.xml 中使用了 com.spotify 插件。    <plugin>      <groupId>com.spotify</groupId>      <artifactId>docker-maven-plugin</artifactId>      <configuration>        <imageName>usermanagementservice</imageName>        <baseImage>openjdk:8-jre-alpine</baseImage>        <entryPoint>["java", "-jar", "/${project.build.finalName}.jar"]</entryPoint>        <!-- copy the service's jar file from target into the root directory of the image -->         <resources>           <resource>             <targetPath>/</targetPath>             <directory>${project.build.directory}</directory>             <include>${project.build.finalName}.jar</include>           </resource>        </resources>      </configuration>    </plugin>这会在我的目标文件夹中创建一个 docker 文件和 .jar 文件： Docker 文件：FROM java:8ENTRYPOINT ["java", "-jar", "/UserManagementService-0.0.1-SNAPSHOT.jar"]
