Question

我是Docker的新手。 Probalby我正在做一些愚蠢的事情。当我在本地构建项目时，可以在没有docker问题的情况下运行它。我的项目配置如下：

application.properties

spring.application.name=dockertest
server.port=8081

pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>ch.meyenberger.webapps</groupId>
    <artifactId>dockertest</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>

    <name>dockertest</name>
    <description>Demo project for Spring Boot</description>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.3.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
        <spring-cloud.version>Finchley.SR1</spring-cloud.version>
        <docker.image.prefix>meyenbergerwebapps</docker.image.prefix>
    </properties>

    <dependencies>
        <dependency>

            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <plugin>
                <groupId>com.spotify</groupId>
                <artifactId>dockerfile-maven-plugin</artifactId>
                <version>1.3.6</version>
                <configuration>
                    <repository>${docker.image.prefix}/${project.artifactId}</repository>
                    <buildArgs>
                        <JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE>
                    </buildArgs>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

Dockerfile

FROM openjdk:8-jdk-alpine
VOLUME /tmp
ARG JAR_FILE
COPY ${JAR_FILE} app.jar
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

因此，当我将代码推送到GitHub存储库时，我配置了自动Docker构建。当我执行docker pull meyenbergerwebapps/dockertest和docker run -p 8081:8081 -t meyenbergerwebapps/dockertest时，总是出现以下错误Error: Invalid or corrupt jarfile /app.jar。我做错了什么？当我手动执行此操作时，它将起作用。

我遵循了本指南 https://spring.io/guides/gs/spring-boot-docker/ ，我看不出有什么区别。谢谢您的帮助！

从错误中我认为您的Jar文件的路径不可访问。您确定要提及jar文件的写入路径吗？你可以试试这个吗？ :cd

Spring / GitHub / Docker-错误：jarfile无效或损坏
