如何在Docker Container中安装/添加jdk 7

Question

我在我的Ubuntu 14.04机器上创建了一个以Python为基础的docker镜像.我使用的Docker版本是1.12.3.用于图像的Python的基本操作系统是Debian.我还需要在我的docker镜像中使用JAVA 7(JDK 7).其中有很少的Python脚本,也很少有需要JDK的脚本.

我能够在我的图像中获得JDK 7,但是从过去的几天它就停止了工作.抛出oracle-jdk-7包不再可用的错误.然后我尝试从Dockerhub获取JDK 7 Dockerfile内容并在dockerfile中添加这些行.它工作了几次然后开始抛出空间不足的错误.

但是空间不是问题,因为'/ var'只占29%.以下是我的Dockerfile内容.

FROM python:2.7

ENV http_proxy http://http.proxy.abc.com:8000
ENV https_proxy http://http.proxy.abc.com:8000

RUN \
  apt-get update && \
  apt-get install -y openjdk-7-jdk && \
  rm -rf /var/lib/apt/lists/*

ENV JAVA_HOME /usr/lib/jvm/java-7-openjdk-amd64

RUN pip install datetime && \
pip install pandas && \
pip install xlrd && \
pip install email && \
pip install Jinja2 && \
pip install bokeh==0.12.4

我也试过跟随jdk 7:

RUN    echo "deb http://ppa.launchpad.net/webupd8team/java/ubuntu precise main" | tee /etc/apt/sources.list.d/webupd8team-java.list && \
       echo "deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu precise main" | tee -a /etc/apt/sources.list.d/webupd8team-java.list && \
       apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys EEA14886 && \
       apt-get update -qq && \
       echo oracle-java7-installer shared/accepted-oracle-license-v1-1 select true | /usr/bin/debconf-set-selections && \
       apt-get install oracle-java7-installer libxext-dev libxrender-dev libxtst-dev -y --no-install-recommends && \
       apt-get clean autoclean && \
       apt-get autoremove --yes && \
       rm -rf /var/lib/{apt,dpkg,cache,log}/ && \
      rm -rf /var/cache/oracle-jdk7-installer

这会引发错误,导致404错误导致下载失败,并且未下载Oracle JDK 7.这个工作正常,直到几天前.

我也尝试了这个.

RUN \
  apt-get update && \
  apt-get install -y openjdk-7-jdk && \
  rm -rf /var/lib/apt/lists/*

这会抛出空间已满的错误.我看到'/ var'只占29%.

也试过这个.

RUN apt-get update && \
    apt-get upgrade -y && \
    apt-get install -y  software-properties-common && \
    add-apt-repository ppa:webupd8team/java -y && \
    apt-get update && \
    echo oracle-java7-installer shared/accepted-oracle-license-v1-1 select true | /usr/bin/debconf-set-selections && \
    apt-get install -y oracle-java8-installer && \
    apt-get clean

这会引发错误,几乎没有包丢失.

请帮我在我的码头图像中获取jdk 7.任何JDK类型都可以.Oracle JDK或打开jdk.

提前致谢.

您的环境包含代理定义

ENV http_proxy http://http.proxy.abc.com:8000
ENV https_proxy http://http.proxy.abc.com:8000

这样,到外部的所有流量都被路由到不存在的位置.删除这些行和docker将能够检索apt资源.

除此之外,我会在这里给你完整的dockerfile:

FROM python:2.7-wheezy

RUN pip install datetime && \
pip install pandas && \
pip install xlrd && \
pip install email && \
pip install Jinja2 && \
pip install bokeh==0.12.4


# add webupd8 repository
RUN \
    echo "===> add webupd8 repository..."  && \
    echo "deb http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main" | tee /etc/apt/sources.list.d/webupd8team-java.list  && \
    echo "deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main" | tee -a /etc/apt/sources.list.d/webupd8team-java.list  && \
    apt-key adv --keyserver keyserver.ubuntu.com --recv-keys EEA14886  && \
    apt-get update  && \
    \
    \
    echo "===> install Java"  && \
    echo debconf shared/accepted-oracle-license-v1-1 select true | debconf-set-selections  && \
    echo debconf shared/accepted-oracle-license-v1-1 seen true | debconf-set-selections  && \
    DEBIAN_FRONTEND=noninteractive  apt-get install -y --force-yes oracle-java8-installer oracle-java8-set-default  && \
    \
    \
    echo "===> clean up..."  && \
    rm -rf /var/cache/oracle-jdk8-installer  && \
    apt-get clean  && \
    rm -rf /var/lib/apt/lists/*

建立它:

 $ docker build -t t .

它是在以下内容构建后产生的:

 $ docker run t java -version
java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)
 $ docker run t python -V
Python 2.7.13

更新:如果你想使用oracle jdk7,只需通过以下方式交换在dockerfile中安装jdk的代码.另请注意,我宁愿在不同的docker容器中保留两个不同的jdks.从不同的图像引用所需的java版本更好,只需在它们拥有的内容之后命名你的构建,例如:docker build -t py27jdk7

# add webupd8 repository
RUN \
    echo "===> add webupd8 repository..."  && \
    echo "deb http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main" | tee /etc/apt/sources.list.d/webupd8team-java.list  && \
    echo "deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main" | tee -a /etc/apt/sources.list.d/webupd8team-java.list  && \
    apt-key adv --keyserver keyserver.ubuntu.com --recv-keys EEA14886  && \
    apt-get update  && \
    \
    \
    echo "===> install Java"  && \
    echo debconf shared/accepted-oracle-license-v1-1 select true | debconf-set-selections  && \
    echo debconf shared/accepted-oracle-license-v1-1 seen true | debconf-set-selections  && \
    DEBIAN_FRONTEND=noninteractive  apt-get install -y --force-yes oracle-java7-installer oracle-java7-set-default  && \
    \
    \
    echo "===> clean up..."  && \
    rm -rf /var/cache/oracle-jdk7-installer  && \
    apt-get clean  && \
    rm -rf /var/lib/apt/lists/*
