+# OpenShift health checks
+
+This directory contains Ansible playbooks for detecting potential problems prior
+to an install, as well as health checks to run on existing OpenShift clusters.
+
+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.
+
+Thus, the playbooks run a battery of checks against the inventory hosts and have
+Ansible gather intermediate errors, giving a more complete diagnostic of the
+state of each host. If any check failed, the playbook run will be marked as
+failed.
+
+To facilitate understanding the problems that were encountered, a custom
+callback plugin summarizes execution errors at the end of a playbook run.
+
+# Available playbooks
+
+1. Pre-install playbook ([pre-install.yml](pre-install.yml)) - verifies system
+   requirements and look for common problems that can prevent a successful
+   installation of a production cluster.
+
+2. Diagnostic playbook ([health.yml](health.yml)) - check an existing cluster
+   for known signs of problems.
+
+3. Certificate expiry playbooks ([certificate_expiry](certificate_expiry)) -
+   check that certificates in use are valid and not expiring soon.
+
+## Running
+
+With a [recent installation of Ansible](../../../README.md#setup), run the playbook
+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. Run the appropriate playbook:
+
+    ```console
+    $ ansible-playbook -i <inventory file> playbooks/byo/openshift-checks/pre-install.yml
+    ```
+
+    or
+
+    ```console
+    $ ansible-playbook -i <inventory file> playbooks/byo/openshift-checks/health.yml
+    ```
+
+    or
+
+    ```console
+    $ ansible-playbook -i <inventory file> playbooks/byo/openshift-checks/certificate_expiry/default.yaml -v
+    ```
+
+## Running via Docker image
+
+This repository is built into a Docker image including Ansible so that it can
+be run anywhere Docker is available. Instructions for doing so may be found
+[in the README](../../README_CONTAINER_IMAGE.md).
