Install JDK 8 update 172 in dockerfile with ubuntu image
提问by doer_uvc
I am used to download java in my dockerfile like this :
我习惯在我的 dockerfile 中下载 java，如下所示：
# Install Java
ENV JAVA_VERSION_MAJOR 8
ENV JAVA_VERSION_MINOR 162
ENV JAVA_VERSION_BUILD 12
ENV JAVA_DOWNLOAD_HASH 0da788060d494f5095bf8624735fa2f1
RUN mkdir -p /usr/lib/jvm \
&& cd /usr/lib/jvm \
&& wget -nv --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/${JAVA_VERSION_MAJOR}u${JAVA_VERSION_MINOR}-b${JAVA_VERSION_BUILD}/${JAVA_DOWNLOAD_HASH}/jdk-${JAVA_VERSION_MAJOR}u${JAVA_VERSION_MINOR}-linux-x64.tar.gz \
&& tar xf jdk-${JAVA_VERSION_MAJOR}u${JAVA_VERSION_MINOR}-linux-x64.tar.gz \
&& rm jdk-${JAVA_VERSION_MAJOR}u${JAVA_VERSION_MINOR}-linux-x64.tar.gz \
&& update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.${JAVA_VERSION_MAJOR}.0_${JAVA_VERSION_MINOR}/bin/java" 1
ENV JAVA_HOME /usr/lib/jvm/jdk1.${JAVA_VERSION_MAJOR}.0_${JAVA_VERSION_MINOR}
Apparently, oracle has released new update 8u172and download within dockerfile is failing with ERROR 404: Not Found.
显然，oracle 已经发布了新的更新8u172并且在 dockerfile 中下载失败ERROR 404: Not Found.
My question is , how do I find out JAVA_DOWNLOAD_HASHvariable ?
我的问题是，如何找出JAVA_DOWNLOAD_HASH变量？
Rest of variable values are clear to me :
其余的变量值对我来说很清楚：
JAVA_VERSION_MAJOR 8
JAVA_VERSION_MINOR 172
JAVA_VERSION_BUILD 11
Please note that my base docker image is : ubuntu:16.04
请注意，我的基本泊坞窗图像是： ubuntu:16.04

I think oracle has fixed broken web8upd.
我认为 oracle 已经修复了broken web8upd.
So now dockerfile specified on githubworks perfectly !
所以现在github上指定的dockerfile完美运行！
Just copy-pasting same dockerfile with some modifications :
只需复制粘贴相同的 dockerfile 并进行一些修改：
FROM ubuntu:16.04
# To solve add-apt-repository : command not found
RUN apt-get -y install software-properties-common
# Install Java
RUN \
echo oracle-java8-installer shared/accepted-oracle-license-v1-1 select true | debconf-set-selections && \
add-apt-repository -y ppa:webupd8team/java && \
apt-get update && \
apt-get install -y oracle-java8-installer --allow-unauthenticated && \
rm -rf /var/lib/apt/lists/* && \
rm -rf /var/cache/oracle-jdk8-installer
# Define commonly used JAVA_HOME variable
ENV JAVA_HOME /usr/lib/jvm/java-8-oracle
Please note : rm -rf /var/lib/apt/lists/*will remove all lists fetched by apt-get update.
请注意：rm -rf /var/lib/apt/lists/*将删除由 获取的所有列表apt-get update。
So if you want to install more things after installing Java, remove rm -rf /var/lib/apt/lists/*otherwise you have to run apt-get updateagain.
所以如果你想在安装后安装更多的东西Java，删除rm -rf /var/lib/apt/lists/*否则你必须apt-get update再次运行。
