* preflight checks: refactor and fix aos_versionLuke Meyer2017-04-081-53/+161
| | | | | | | | | | | Bring in openshift_repos to provide Origin repo before checks on Origin. For OCP we want the check to fail if both version 3.3 and version 3.4 are available - they shouldn't have both channels enabled. For Origin everything is in one repo so it's not surprising to find 1.4 and 1.5 versions available. Added unit tests as well.
* vendor patched upstream docker_container module.juanvallejo2017-03-231-0/+2036
| | | | | | | | | | | | | | | | Due to the use of a restricted name in the core `docker_container` module's result, any standard output of a docker container captured in the module's response was stripped out by ansible. Because of this, we are forced to vendor a patched version of this module, until a new version of ansible is released containing the patched module. This file should be removed once we begin requiring a release of ansible containing the patched `docker_container` module. This patch was taken directly from upstream, with no further changes: 20bf02f6b96356ab5fe68578a3af9462b4ca42a5
* add docker_image_availability checkjuanvallejo2017-03-231-0/+24
| | | | | | | | This patch adds a check to ensure that required docker images are available in at least one of the registries supplied in an installation host. Images are available if they are either already present locally, or able to be inspected using Skopeo on one of the configured registries.

* Replace multi-role checks with action pluginRodolfo Carvalho2017-02-102-0/+190
This approach should make it easier to add new checks without having to write lots of YAML and doing things against Ansible (e.g. ignore_errors). A single action plugin determines what checks to run per each host, including arguments to the check. A check is implemented as a class with a run method, with the same signature as an action plugin and module, and is normally backed by a regular Ansible module. Each check is implemented as a separate Python file. This allows whoever adds a new check to focus solely in a single Python module, and potentially an Ansible module within library/ too. All checks are automatically loaded, and only active checks that are requested by the playbook get executed.
