= Spring Boot Launch Script Tests This module contains integration tests for the default launch script that is used to make a jar file fully executable on Linux. The tests use Docker to verify the functionality in a variety of Linux distributions. == Setting up Docker The setup that's required varies depending on your operating system. === Docker on OS X Install Docker for Mac. See the https://docs.docker.com/docker-for-mac/install/[macOS installation instructions] for details. === Docker on Linux Install Docker as appropriate for your Linux distribution. See the https://docs.docker.com/engine/installation/[Linux installation instructions] for more information. Next, add your user to the `docker` group. For example: ---- $ sudo usermod -a -G docker awilkinson ---- You may need to log out and back in again for this change to take effect and for your user to be able to connect to the daemon. == Running the tests NOTE: You need Java 8 to run the integration tests as they are currently skipped for Java 9 and later. You're now ready to run the tests. Assuming that you're in the same directory as this README, the tests can be launched as follows: ---- $ gradle intTest ---- The first time the tests are run, Docker will create the container images that are used to run the tests. This can take several minutes, particularly if you have a slow network connection. Subsequent runs will be faster as the images are cached locally. You can run `docker images` to see a list of the cached images. Images created by these tests will be tagged with `spring-boot-it` prefix to easily distinguish them. == Cleaning up If you want to reclaim the disk space used by the cached images (at the expense of having to wait for them to be downloaded and rebuilt the next time you run the tests), you can use `docker images` to list the images and `docker rmi <image>` to delete them (look for `spring-boot-it` tag). See `docker rmi --help` for further details.
