Java-Service-API

This app is used to start a docker container, in which the java code is compiled and executed.

To build the app run:

mvn clean package

To run the app go to target directory and run:

java -jar java-service-api-0.0.1-SNAPSHOT.jar

To change the location where the app saves the generated java files you will have to modify the property CLASS_DIRECTORY from Constants class.

How to configure a new jdk version:

First you will have to create a Dockerfile in the project java-runner-config

To configure a new Dockerfile in java-runner-config create a new Dockerfiel with the following name format:

jdk_version.Dockerfie

Example: openjdk_10.Dockerfile

The content of the new file should be:

FROM jdk-image:version

ENV GOTTY_TAG_VER v1.0.1

RUN apt-get -y update && \
   apt-get install -y curl && \
   curl -sLk https://github.com/yudai/gotty/releases/download/${GOTTY_TAG_VER}/gotty_linux_amd64.tar.gz \
   | tar xzC /usr/local/bin && \
   apt-get purge --auto-remove -y curl && \
   apt-get clean && \
   rm -rf /var/lib/apt/lists*

COPY ./gotty_config/gotty /gotty

For previous example the following code will be valid:

FROM openjdk:10.0.1-10-jdk-slim

ENV GOTTY_TAG_VER v1.0.1

RUN apt-get -y update && \
    apt-get install -y curl && \
    curl -sLk https://github.com/yudai/gotty/releases/download/${GOTTY_TAG_VER}/gotty_linux_amd64.tar.gz \
    | tar xzC /usr/local/bin && \
    apt-get purge --auto-remove -y curl && \
    apt-get clean && \
    rm -rf /var/lib/apt/lists*

COPY ./gotty_config/gotty /gotty

After the Docker file have been created you will have to build it:

docker build -t repository:tag -f Dockerfile_name .

For previous example the following command is valid:

docker build -t x-openjdk:10 -f openjdk_10.Dockerfile .

After you have built the image you will need to create a new Dockerfile and put it in the directory resources/dockerfile from this project. The name of the file can be the same as the previous file jdk_version.Dockerfile.

This Dockerfile will have as a base image the image that has been built at a previous step.

Example of content for the new file:

FROM x-openjdk:10

ARG COPY_PATH

COPY ${COPY_PATH} /classes
WORKDIR /classes

CMD ["sh","-c", "javac Main.java && java Main"]
ENTRYPOINT ["/usr/local/bin/gotty","--permit-write", "--once", "--config", "/gotty"]
