docker-tempest-openstack

Docker container to run smoke tests against an OpenStack environment. It is not dangerous (unless you intentionally run the stress tests) by running it without args.

To build the Docker container ./build.sh (name of the image creaded: tempest). Type docker images to see it.
To run the container, do the auto-configuration and list all the tests, just put a openrc.sh file in this folder (admin or other user/project with admin role) and type ./run.sh without args. Without args it will list all the test available and a tempest folder will be created to store the test repository.

Configuration

You can provide your own tempest configuration by creating these files in this folder (apart of the openrc.sh file) before running ./run.sh for first time:

tempest.conf
accounts.yaml
logging.conf

If those files are found, no autoconfiguration will be done. Otherwise, the container will try to find out the tempest settings for your environment, by using the OpenStack client openstack.

Autoconfiguration is not easy for complicated environments, so in order to help or for fine tuning, you can provide some variables, have a look at run.sh and adapt it for your environment.

By default it uses ostestr command to run the tests: http://docs.openstack.org/developer/os-testr/readme.html but it is possible to switch to testr by defining TEMPEST_COMMAND=testr

Examples

Tempest repository is created in tempest.

To see the list of available tests: ./run.sh

To run help: ./run.sh --help

To run api tests with pretty print and one test at a time (concurrency == 1) : ./run.sh -p -c 1 --regex '(^tempest\.(api))'

Hacking the container

Go to docker folder and:

conf are the files will be copied to \etc\tempest
confd is the configuration for confd and the template for tempest autoconfiguration file.
bin includes the entrypoint (init.sh) and the confd utility.
init includes the files for initialization and autoconfiguration which are launched from bin\init.sh', otherwise they could run using the my_initsystem ofphusion/baseimage`

Known problems

Autoconfiguration is done the fist time that tempest folder is created, after the first run the openrc file is not needed anymore. If you need to make changes after the first time, go to tempest/etc folder and change the contents there.
tempest folder creates files owner by root. Internally, within the container, the process runs as root and it creates all the files as root uid in tempest. From the host operating system, one cannot go into the folder because the files are owned by root. Workaround, use "sudo"
It seems tempest github repository does not use tags (there are tags, but too old) or branches, so, when the container is built it always will get the master branch. I recommend tagging the docker images once they are created and upload them to a registry.
