The intent of using dynamic inventory is that a test can supply its own inventory files in the test/inventory directory. These may be completely different than the standard-inventory-* scripts ... or (in this case) these test/inventory scripts may setup certain environment variables and then invoke other inventory files.

I would suggest the following approach:

• The /usr/share/ansible/inventory/standard-inventory-docker accepts additional arguments.
• Tests which need to pass additional arguments, create their own inventory directory containing wrapper inventory scripts which invoke the standard-inventory-* inventory scripts with additional arguments.

Thank you for the suggestions. I'll start progress using that approach.

PR #33 should be sufficient to address this issue by enabling extra arguments for "docker run" to be taken from the DOCKER_EXTRA_ARGS environment variable. The rest is left up to a custom inventory script to be written and included in the tests/inventory directory.

This issue is addressed by PR #33, included in package update standard-test-roles-2.1 which is currently making its way to the rawhide and updates-testing repos. Note: the environment variable name was changed to TEST_DOCKER_EXTRA_ARGS.

As noted above, it is still up to each test to supply (an) appropriate inventory wrapper script(s) to provide the necessary settings to the scripts installed in /usr/share/ansible/inventory.

See PR#36 for an inventory merge script that finishes resolving this issue by allowing a single simple custom inventory script to wrap all of the scripts installed in /usr/share/ansible/inventory.

PR#36 solves this issue. Closing.
