= 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
|
|
|
|
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.
