spring - docker 运行-错误:无法访问jarfile

Question

我是dockers的新手
我正在尝试在Mac上运行:

docker 运行eloomina1 / datacollector

返回:

Error: Unable to access jarfile dataCollector-0.0.1-SNAPSHOT.jar

我已经检查过，它不是该文件的权限。
我正在建立这样的形象:

docker build --build-arg JAR_FILE = dataCollector-0.0.1-SNAPSHOT.jar -t eloomina1 / datacollector。

我的dockerfile:

    FROM adoptopenjdk/openjdk12:latest
    MAINTAINER Shahar Wider <shahar@ttt.com>
    VOLUME /tmp
    ARG JAR_FILE
    COPY target/${JAR_FILE} dataCollector.jar
    ENTRYPOINT ["java","-jar","dataCollector-0.0.1-SNAPSHOT.jar"]

我的pom.xml:

<groupId>com.eloomina</groupId>
<artifactId>dataCollector</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>dataCollector</name>

<properties>
    <java.version>12</java.version>

Answer 1

图像内的jar文件的名称为dataCollector.jar，因为您使用了COPY命令，如下所示:

COPY target/${JAR_FILE} dataCollector.jar

所以ENTRYPOINT应该是:

ENTRYPOINT ["java","-jar","dataCollector.jar"]
