* Remove unnecessary codeRodolfo Carvalho2017-04-041-5/+1

* Make resolve_checks more strictRodolfo Carvalho2017-04-041-21/+33
| | | | | So that all names it return are directly usable, without checking for existence.
* Test OpenShift health check loaderRodolfo Carvalho2017-03-281-1/+3

* Rename module_executor -> execute_moduleRodolfo Carvalho2017-03-281-1/+1
| | | | | | | | It is a function/callable, the name should imply action, should be a verb and not a noun. Keep supporting the old name while we have PRs in-flight that use the old name.
* add docker_image_availability checkjuanvallejo2017-03-231-0/+1
| | | | | | | | 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.
* Introduce tag notation for checksRodolfo Carvalho2017-02-101-1/+22
| | | | This allows us to refer to a group of checks using a single handle.
* Replace multi-role checks with action pluginRodolfo Carvalho2017-02-101-0/+95
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.
