| # Run RAS test: Unsafe Shutdown Local. | |
| # | |
| # This workflow is run on 'self-hosted' runners. | |
| # | |
| # RAS tests require a different approach compared to the standard tests - they need to | |
| # reboot the runner during the test. Normally, rebooting and continuing the job on GHA | |
| # is not possible, due to losing connection with the runner. To work around this issue, | |
| # an additional runner (not connected to the GH) runs the tests instead. | |
| # | |
| # The general idea of the solution is: | |
| # - First platform [self-hosted runner] functions as the controller [ras_controller], | |
| # - Second platform functions as the test runner [ras_runner], | |
| # - The workflow launches its steps on the controller, | |
| # - The controller will then run an ansible playbook on the second platform [ras_runner], | |
| # with options provided by the workflow, | |
| # - The test runner follows the steps given by the controller, | |
| # running the tests in the process and providing results as output, | |
| # - The controller gathers this output and prints it in GHA job. | |
| # | |
| # The only drawback of this idea is that workflow would always finish successfully. | |
| # The solution was added as an additional step, at the end of the workflow, parsing the output. | |
| # | |
| # More detailed information about the ansible playbook and tests themselves can be found in: | |
| # utils/gha-runners/run-ras-linux.yml | |
