execute Ant from docker-compose

I'm a newbie with docker.

I'm creating a dockerfile, and want to execute hello world from Ant file "build.xml" with docker commands. Is this possible?

Solution

  • This is a quick solution:

    1. create a folder "ant"
    2. create a file ant/Dockerfile with the contents
    FROM alpine

WORKDIR /work

RUN apk update && apk add openjdk8 && apk add apache-ant

ENTRYPOINT [ "ant" ]
    1. create a file ant/build.xml with the contents (I know you can do better than this but I can't :) )
    <?xml version = "1.0"?>
<project name = "Hello World Project" default = "info">
   <target name = "info">
      <echo>Hello World - Welcome to Apache Ant!</echo>
   </target>
</project>
    1. build the docker image
    docker build -t ant:1.0 ./ant
    1. run the ant build
    docker run --rm -v $(pwd)/ant:/work ant:1.0

    Of course you can put in "ant" your whole project and build that.

    This can be refined, but hopefully it answers your question so far.
