# Docker Registry Integration Testing

|
|
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](https://github.com/docker/golem)
|
|
|
|
|
|
|
|
|
|
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).
|
|
|
|
|
|
|
|
|
|
## Running integration tests
|
|
|
|
|
|
|
|
|
|
### Run using multiversion script
|
|
|
|
|
|
|
|
|
|
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 `./run_multiversion.sh -d`.
|
|
|
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
|
|
|
### Run manually using Golem
|
|
|
|
|
|
|
|
|
|
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.

|
#### Installing Golem
|
|
|
|
|
|
|
|
|
|
Golem is distributed as an executable binary which can be installed from
|
|
|
|
|
the [release page](https://github.com/docker/golem/releases/tag/v0.1).
|
|
|
|
|
|
|
|
|
|
#### Running golem with docker

|
|
|
Additionally golem can be run as a docker image requiring no additional
|
2016-04-12 21:03:56 +00:00
|
|
|
installation.
|
|
|
|
|
|
2020-08-24 11:18:39 +00:00
|
|
|
`docker run --privileged -v "$GOPATH/src/github.com/distribution/distribution/contrib/docker-integration:/test" -w /test distribution/golem golem -rundaemon .`
|

|
|
|
|
|
|
|
|
#### Golem custom images
|
|
|
|
|
|
|
|
|
|
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 .`
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
#### Use golem caching for developing tests
|
|
|
|
|
|
|
|
|
|
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 .`
|
