### Images ### Images
There are three types of Docker images here: the Java Development Kit (JDK), the Java Runtime Environment (JRE) and a small footprint version of the JDK (slim). These images can be used as the basis for custom built images for running your applications.

##### Alpine Linux
Consider using [Alpine Linux](http://alpinelinux.org/) if you are concerned about the size of the overall image. Alpine Linux is a stripped down version of Linux that is based on [musl libc](http://wiki.musl-libc.org/wiki/Functional_differences_from_glibc) and Busybox, resulting in a [Docker image](https://hub.docker.com/_/alpine/) size of approximately 5 MB. Due to its extremely small size and reduced number of installed packages, it has a much smaller attack surface which improves security. The OpenJDK binaries built by AdoptOpenJDK currently have a dependency on gnu glibc, the sources can be found [here](https://github.com/sgerrand/docker-glibc-builder/releases/). Installing this library adds an extra 8 MB to the image size.

### How to use this Image ### How to use this Image
To run a pre-built jar file with the latest OpenJDK 8 with HotSpot JRE image, use the following Dockerfile: To run a pre-built jar file with the latest OpenJDK 11 with HotSpot JRE image, use the following Dockerfile:
```dockerfile ```dockerfile
