# What is Groovy?
|
|
|
|
[Apache Groovy](http://groovy-lang.org/) is a powerful, optionally typed and dynamic language, with static-typing and static compilation capabilities, for the Java platform aimed at improving developer productivity thanks to a concise, familiar and easy to learn syntax. It integrates smoothly with any Java program, and immediately delivers to your application powerful features, including scripting capabilities, Domain-Specific Language authoring, runtime and compile-time meta-programming and functional programming.

# How to use this image
|
|
|
|
Note that if you are mounting a volume and the uid running Docker is not `1000`, you should run as user `root` (`-u root`).
|
|
|
|
## Starting Groovysh
|
|
|
|
`docker run -it --rm groovy`
|
|
|
|
## Running a Groovy script
|
|
|
|
`docker run --rm -v "$PWD":/home/groovy/scripts -w /home/groovy/scripts groovy groovy <script> <script-args>`
|
|
|
|
## Reusing the Grapes cache
|
|
|
|
The local Grapes cache can be reused across containers by creating a volume and mounting it in `/home/groovy/.groovy/grapes`.
|
|
|
|
```console
|
|
docker volume create --name grapes-cache
|
|
docker run --rm -it -v grapes-cache:/home/groovy/.groovy/grapes groovy
|
|
```
|
|
|
|
# Image Variants
|
|
|
|
The `groovy` images come in many flavors, each designed for a specific use case.
|
|
|
|
## `groovy:<version>`
|
|
|
|
This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container (mount your source code and start the container to start your app), as well as the base to build other images off of.
|
|
|
|
## `groovy:<version>-alpine`
|
|
|
|
This image is based on the popular [Alpine Linux project](https://alpinelinux.org), available in [the `alpine` official image](https://hub.docker.com/_/alpine). Alpine Linux is much smaller than most distribution base images (~5MB), and thus leads to much slimmer images in general.
|
|
|
|
This variant is useful when final image size being as small as possible is your primary concern. The main caveat to note is that it does use [musl libc](https://musl.libc.org) instead of [glibc and friends](https://www.etalabs.net/compare_libcs.html), so software will often run into issues depending on the depth of their libc requirements/assumptions. See [this Hacker News comment thread](https://news.ycombinator.com/item?id=10782897) for more discussion of the issues that might arise and some pro/con comparisons of using Alpine-based images.
|
|
|
|
To minimize image size, it's uncommon for additional related tools (such as `git` or `bash`) to be included in Alpine-based images. Using this image as a base, add the things you need in your own Dockerfile (see the [`alpine` image description](https://hub.docker.com/_/alpine/) for examples of how to install packages if you are unfamiliar).
