How to use this image
Start a Java instance in your app
The most straightforward way to use this image is to use a Java container as both the build and runtime environment. In your
Dockerfile, writing something along the lines of the following will compile and run your project:
FROM openjdk:7 COPY . /usr/src/myapp WORKDIR /usr/src/myapp RUN javac Main.java CMD ["java", "Main"]
You can then run and build the Docker image:
$ docker build -t my-java-app . $ docker run -it --rm --name my-running-app my-java-app
Compile your app inside the Docker container
There may be occasions where it is not appropriate to run your app inside a container. To compile, but not run your app inside the Docker instance, you can write something like:
$ docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp openjdk:7 javac Main.java
This will add your current directory as a volume to the container, set the working directory to the volume, and run the command
javac Main.java which will tell Java to compile the code in
Main.java and output the Java class file to
