However, +when performing checks, it is useful to gather as much information about +problems as possible in a single run. + +The `check.yml` playbook runs a battery of checks against the inventory hosts +and tells Ansible to ignore intermediate errors, thus giving a more complete +diagnostic of the state of each host. Still, if any check failed, the playbook +run will be marked as having failed. + +To facilitate understanding the problems that were encountered, we provide a +custom callback plugin to summarize execution errors at the end of a playbook +run. + +--- + +*Note that currently the `check.yml` playbook is only useful for RPM-based +installations. Containerized installs are excluded from checks for now, but +might be included in the future if there is demand for that.* + +--- + +## Running + +With an installation of Ansible 2.2 or greater, run the playbook directly +against your inventory file. Here is the step-by-step: + +1. If you haven't done it yet, clone this repository: + + ```console + $ git clone https://github.com/openshift/openshift-ansible + $ cd openshift-ansible + ``` + +2.
