-# OpenShift 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. Run the playbook:
-
- ```console
- $ ansible-playbook -i <inventory file> playbooks/byo/openshift-preflight/check.yml
- ```
