 The [Dockerfile](Dockerfile) in this repository uses the [playbook2image](https://github.com/aweiteka/playbook2image) source-to-image base image to containerize `openshift-ansible`. The resulting image can run any of the provided playbooks.
 
-**Note**: at this time there are known issues that prevent to run this image for installation/upgrade purposes from within one of the hosts that is also an installation target at the same time: if the playbook you want to run attempts to manage the docker daemon and restart it (like install/upgrade playbooks do) this would kill the container itself during its operation.

 At the very least, when running a container using an image built this way you must specify:
 
-1. The **playbook** to run. This is set using the `PLAYBOOK_FILE` environment variable.
 1. An **inventory** file. This can be mounted inside the container as a volume and specified with the `INVENTORY_FILE` environment variable. Alternatively you can serve the inventory file from a web server and use the `INVENTORY_URL` environment variable to fetch it.
 1. **ssh keys** so that Ansible can reach your hosts. These should be mounted as a volume under `/opt/app-root/src/.ssh`
+1. The **playbook** to run. This is set using the `PLAYBOOK_FILE` environment variable. If you don't specify a playbook the [`openshift_facts`](playbooks/byo/openshift_facts.yml) playbook will be run to collecting and show facts about your OpenShift environment.
 
-Here is an example of how to run a containerized `openshift-ansible` playbook that will check the expiration dates of OpenShift's internal certificates using the [`openshift_certificate_expiry` role](../../roles/openshift_certificate_expiry). The inventory and ssh keys are mounted as volumes (the latter requires setting the uid in the container and SELinux label in the key file via `:Z` so they can be accessed) and the `PLAYBOOK_FILE` environment variable is set to point to an example certificate check playbook that is already part of the image:
