These integration tests cover interactions between registry clients such as the docker daemon and the registry server. All tests can be run using the golem integration test runner
The integration tests configure components using docker compose (see docker-compose.yaml) and the runner can be using the golem configuration file (see golem.conf).
The integration tests in the
contrib/docker-integration directory can be simply run by executing the run script
./run_multiversion.sh. If there is no running daemon to connect to, run as
This command will build the distribution image from the locally checked out version and run against multiple versions of docker defined in the script. To run a specific version of the registry or docker, Golem will need to be executed manually.
Using the golem tool directly allows running against multiple versions of the registry and docker. Running against multiple versions of the registry can be useful for testing changes in the docker daemon which are not covered by the default run script.
Golem is distributed as an executable binary which can be installed from the release page.
Additionally golem can be run as a docker image requiring no additional installation.
docker run --privileged -v "$GOPATH/src/github.com/docker/distribution/contrib/docker-integration:/test" -w /test distribution/golem golem -rundaemon .
Golem tests version of software by defining the docker image to test.
Run with registry 2.2.1 and docker 1.10.3
golem -i golem-dind:latest,docker:1.10.3-dind,1.10.3 -i golem-distribution:latest,registry:2.2.1 .
Golem allows caching image configuration to reduce test start up time. Using this cache will allow tests with the same set of images to start up quickly. This can be useful when developing tests and needing the test to run quickly. If there are changes which effect the image (such as building a new registry image), then startup time will be slower.
Run this command multiple times and after the first time test runs should start much quicker.
golem -cache ~/.cache/docker/golem -i golem-dind:latest,docker:1.10.3-dind,1.10.3 -i golem-distribution:latest,registry:2.2.1 .
