This docker image includes Java 8, Grails 3.2.8 & Python 3 for use in developing Grails applications (with the Grails cli as the endpoint).
By defaut, running this image without any command will run
grails -version in the /app directory. Thus, you should mount your project in /app. For example, a more interesting command would be test-running your app.
# For files on the dockerhost docker run --rm -v /path/to/your/project:/app:rw -p 80:8080 --name grails explorite/grails3-python grails run-app # For a data container docker run --rm --link data-container-name:data -p 80:8080 --name grails explorite/grails3-python grails run-app
Of course, you can use any command here, and take notice that
grails is the entrypoint. So, to create an application, run the following:
docker run --rm -v /path/to/dir:/app:rw --name grails explorite/grails3-python create-app helloworld
Downloading a whole bunch of things each time you run the container is a pain -- not to mention a huuge bandwidth sink ( for everyone else stuck in 1995 internet with me ). A nice feature of Grails is its interactive mode. Also useful if you find yourself starting a grails container frequently, you can set the docker switches -i and -t and the grails switch
--interactive (see example). This overrides the default CMD (
-version) if you didn't change it.
docker run -it --rm -v /path/to/project:/app:rw --name grails explorite/grails3-python --interactive
Building On This Container
grails -version is not a very interesting command. So, when want to customize or get annoyed with changing your project's user and group, you can build off of this image and tweak all the settings, install more packages, etc:
FROM explorite/grails3-python MAINTAINER your-name-here <email@example.com> # In case someone loses the Dockerfile RUN rm -rf /etc/Dockerfile ADD Dockerfile /etc/Dockerfile # Add your desired user and group RUN groupadd your-group-name RUN useradd -s /bin/bash -m -d /app -g your-group-name your-user-name # Set your desired user as default USER your-user-name # Whatever default behavior you want ENTRYPOINT ["grails"] CMD ["run-app"]
Get the Image
To build this image yourself, run...
