docker-使用curl安装Java 8

Question

To insall java 8 on docker container, I used this command in dockerfile

RUN curl -LO 'http://download.oracle.com/otn-pub/java/jdk/8u111-b14/jdk-8u111-linux-x64.rpm'
-H 'Cookie: oraclelicense=accept-securebackup-cookie' RUN rpm -i jdk-8u111-linux-x64.rpm RUN rm jdk-8u111-linux-x64.rpm

It worked for awhile, but now this link is not no longer available. Is there replaceable url for this? or easy way to insall java 8 on docker?

Answer 1

It's up to your using OS, so I'd like you to show your OS. For example, Ubuntu users prepares their ppa repository for Oracle Java.

RUN add-apt-repository ppa:webupd8team/java
RUN apt-get update
RUN apt-get install oracle-java8-installer

Answer 2

It seems that Oracle has changed the authorization for downloading, the actual link that the browser uses is http://download.oracle.com/otn-pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-x64.rpm?AuthParam=1496223138_c808095f7637d83147c37d69d3a87e7a , but this cannot be used with curl.

I have no solution for the problem with downloading from Oracle, but I use the official OpenJDK image as base and have found no problems with that.

Answer 3

If openjdk is OK for you, you can use

RUN apt-get install -y openjdk-8-jdk

openjdk, in contrast to oracle, does not require user's confirmation.

If you only need java runtime, consider openjdk-8-jre .

Adaption of my Dockerfile from https://hub.docker.com/r/sftech/java

FROM ubuntu

ENV JAVA_VERSION=8

RUN echo oracle-java${JAVA_VERSION}-installer shared/accepted-oracle-license-v1-1 select true | /usr/bin/debconf-set-selections
RUN apt-get update \
 && apt-get install -y software-properties-common \
 && apt-add-repository ppa:webupd8team/java \
 && apt-get update \
 && apt-get install -y oracle-java${JAVA_VERSION}-installer \
 && update-java-alternatives -s java-${JAVA_VERSION}-oracle \
 && apt-get clean \
 && rm -rf /var/lib/apt/lists/*

Answer 5

Why would you install java in an image / container, when you can get a java:8 image from the Docker store for free. The license requirements are exactly the same as the java / jdk download install from the oracle.com website.
