+# Preflight checks
+
+Here we provide an Ansible playbook for detecting potential roadblocks prior to
+an install or upgrade.
+
+Ansible's default operation mode is to fail fast, on the first error. 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. Configure a custom callback plugin to get a summary of problems at the end of
+the playbook run:
+
+ ```console
+ $ export ANSIBLE_CALLBACK_PLUGINS=callback_plugins \
+ ANSIBLE_STDOUT_CALLBACK=default_plus_summary
+ ```
+
+3. Run the playbook:
+
+ ```console
+ $ ansible-playbook -i <inventory file> playbooks/adhoc/preflight/check.yml
+ ```
