Docker How To Install Java

Installing Java in a docker container is easy. You just need to copy in the JDK and install it as you normally would. This can be done in a dockerfile. You could also, alternatively, use your systems package manager.

This is a trimmed down example of a docker file that would install Java in a container:

vi Dockerfile


FROM standard

#COPY jdk-13.0.1_linux-x64_bin.tar.gz /
#RUN tar xvfz jdk-13.0.1_linux-x64_bin.tar.gz
#RUN rm jdk-13.0.1_linux-x64_bin.tar.gz
#RUN cp -r jdk-13.0.1 /opt
#RUN cd /opt && ln -s jdk-13.0.1 java

COPY jdk-7u15-linux-x64.tar.gz /
RUN tar xvfz jdk-7u15-linux-x64.tar.gz
RUN rm jdk-7u15-linux-x64.tar.gz
RUN cp -r jdk1.7.0_15 /opt
RUN cd /opt && ln -s jdk1.7.0_15 java

CMD ["/usr/bin/supervisord"]

Build an image:

docker build -t mytestimage

This is based on my “standard” image. See the example in this lab case study for more details:
