如何将AdoptOpenJDK添加到Docker镜像中？

Question

我已经创建了一个通用的docker构建文件，其中包括kubectl和Helm等实用程序，但现在我想将adoptopenjdk与Maven一起添加到映像中，但是当我测试它时，Java会因为核心转储而崩溃。

下面是Dockerfile：

JDK_FILE "OpenJDK11U-jdk_x64_linux_hotspot_11.0.4_11.tar.gz“直接从https://adoptopenjdk.net/releases.html?variant=openjdk11&jvmVariant=hotspot下载。

一个非常简单的Java测试文件：

class HelloWorld 
{ 
    public static void main(String args[]) 
    { 
        System.out.println("Hello, World"); 
    } 
}

我正在通过GitLab管道构建它：

image: ${BUILD_URL}/tools/build/docker-build-test-image/add-jdk:20191129.33

stages:
  - build

build:
  stage: build
  script:
    - java -version
    - javac HelloWorld.java
    - java HelloWorld

下面是输出：

你能告诉我我做错了什么吗？

如果你构建在基本的高山之上，你可以添加open-jdk和maven。它可能看起来像这样：

from alpine:3.10

run apk --no-cache add openjdk11 --repository=http://dl-cdn.alpinelinux.org/alpine/edge/community
run apk add bash vim curl wget jq docker git tar unzip bash-completion ca-certificates
run cd /opt && curl -sSl http://mirror.vorboss.net/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz | tar -xz

env PATH "$PATH:/opt/apache-maven-3.6.3/bin"
entrypoint ["/bin/bash"]

这将使用java 11和最新的maven设置一个高山图像(在撰写本文时)。通常，我们会使用一个run命令来最小化图像中的层数，但我将把这种优化留给您的想象力。

我已经添加了一行代码，显示如何以及在哪里安装其他工具，如Docker、bash、vim、curl等。其中一些工具用于安装maven (tar解压缩)，而另一些工具仅用于装饰。您只需要使用curl、tar和unzip来回答这个问题，但是当您正在构建一个devbox时，我想我应该添加一些用于演示。

当你决定在这样的项目中使用哪个基础镜像时，最好是从基础操作系统开始，比如apline:3，而不是一些随机的镜像，它恰好安装了你需要的东西(在你的例子中是git)。像OO一样对待它--您继承了git镜像，因此您也是一个git镜像。在你的例子中，你不是一个真正的git镜像，你是一把瑞士军刀，你不知道另一个选择的底层操作系统到底是什么(如果你使用:latest作为标签，你不知道它将来会变成什么)。
