Preparing docker images for integration tests
Our test suite relies heavily on custom docker images for testing. The main reason that we use custom images is test speed: having prepared docker images vs. building them on each test execution saves a ton of time.
Adding a new image is relatively straightforward process. We can just copy one
of the preexisting definitions from the docker directory and update it. All
docker files should have a name in the format of
To build and publish our image, we can run the docker/build.sh script:
$ cd docker $ ./build.sh sensu-5.21.0.docker
Note that the command will add a sensu-go-tests- prefix to all images. In the previous example, the build script will build the quay.io/xlab-steampunk/sensu-go-tests-sensu:5.21.0 image.
