How to run jpos inside a docker container?

Question

I want to run jpos (isoserver) within a docker container. So far I have found this image in Docker hub. I didn't able to found any details documentation about this image. Only few lines are available in readme.

I have found few Docker files and build was successful.But when I try to run , it takes me to a bash prompt.I have run this command

docker run -t -i jpos/ubuntu_trusty_jdk8 /bin/bash

No q2 server is running. No Logs are available in docker container when i try to run this command.

sudo docker logs 7c2661e82141

Can I use existing docker image for my requirements? If yes ,where are the details documentation for how to run, modify existing docker image?

Can anybody help?

You can take a look at the Docker files.

If you use the jPOS-template, you can create a Dockerfile of your own, like this:

FROM jpos/ubuntu_jdk8:latest

ADD jpos/build/distributions/jpos*.tar.gz /
LABEL vendor="jPOS.org"
LABEL org.jpos.template="2.1.1 master/2a2874f"
RUN ln -s /jpos-2.1.1 /jpos
WORKDIR /jpos

CMD ["bin/q2"]

Then you can build your image with a script like this:

!/bin/bash

cd `dirname $0`
rm -fr jpos 
git clone https://github.com/jpos/jPOS-template.git jpos
(cd jpos && gradle dist)
docker rmi jpos/template
docker build -t="jpos/yourproject" .

(You obviously clone from your project, based on jPOS-template).

Key points here:

• gradle dist creates a distribution in build/distributions directory
• ADD jpos/build/distributions/jpos*.tar.gz / in the Dockerfile expands the tarball inside your container.
