Alpine 的自定义运行时图像

Question

我正在尝试使用 The Badass Runtime Plugin 创建自定义运行time 图像，然后在 Alpine 上执行它。但它失败并显示以下错误消息。

jibcmd_1  | /bin/sh: exec: line 1: ./bin/jibcmd: not found

如果我执行类似 docker run -it jibcmd_jibcmd ls -l /app/bin/jibcmd 的操作，毫无疑问该文件就在那里。

如果我将父映像从 Alpine 更改为 Debian，一切正常。但是我想用Alpine。

下面是我的build.gradle文件

plugins {
    id 'java'
    id 'org.jetbrains.kotlin.jvm' version '1.3.61'
    id 'application'
    id "com.github.johnrengelman.shadow" version "5.2.0"
    id "org.beryx.runtime" version "1.8.0"
}

group 'org.example'
version '1.0.0'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8"
    implementation "com.github.ajalt:clikt:2.3.0"
    implementation "com.google.cloud.tools:jib-core:0.12.0"
    testCompile group: 'junit', name: 'junit', version: '4.12'

    implementation 'org.glassfish.jaxb:jaxb-runtime:2.4.0-b180830.0438'
    implementation 'com.sun.xml.ws:jaxws-ri:2.3.2'
}

runtime {
    modules = ['java.logging', 'java.desktop', 'java.compiler', 'java.xml']
}

compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

下面是我的 Dockerfile

FROM openjdk:14-jdk-buster AS builder
WORKDIR /src

COPY *.gradle *.properties gradlew ./
COPY gradle gradle
RUN ./gradlew --version

COPY . .
RUN ./gradlew jpackageImage

FROM alpine
#FROM debian
WORKDIR /app
COPY --from=builder /src/build/jpackage/jibcmd .
CMD exec ./bin/jibcmd

关于如何在 Alpine 上运行有什么建议吗？

ldd 仍然声称 ld-linux-x86-64.so.2 丢失了...

这可以通过使用带有 Glibc 的 Alpine 映像来解决
