[DOCKER] How to make a Java container


What if you manage your Java application environment with Kubernetes? First, build the development environment in a container to answer


The functions are as follows Java


You will be able to create a development environment from a Dockerfile. Even if you do not want to publish the configuration information locally or in a dedicated development environment, you can create the same environment anywhere by sharing the Dockerfile.


Docker installed Mac


First of all, preliminary research "Something" features like Java containers and ssh connection settings should have been accomplished by great men!

First, search on Docker Hub https://hub.docker.com/

I didn't have a good one, so I decided to make it from Dockerfile.

Creating an environment

To home directory cd

Open a terminal and create a working folder mkdir myproject

Go to working folder cd myproject

Create a Dockerfile vi Dockerfile


FROM ubuntu:latest

ENV JAVA_HOME /usr/lib/jvm/java-8-oracle

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

CMD "/bin/bash"

Generate image from Dockerfile docker build -t testtest . Don't forget the last "."

After a short time

Successfully built 51fe1ec9021b Successfully tagged test:latest There is a display like this, and the image is finished.

Make sure the image exists docker images A list of owned images is output, and if there is "testtest", it is OK

Run the image docker run -i -t testtest java -version

OK if the output is as follows

java version "1.8.0_201" Java(TM) SE Runtime Environment (build 1.8.0_201-b09) Java HotSpot(TM) 64-Bit Server VM (build 25.201-b09, mixed mode)

Thank you for your hard work.
