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 -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. - -4. Adhoc playbook ([adhoc.yml](adhoc.yml)) - use it to run adhoc checks or to - list existing checks. - See the [next section](#the-adhoc-playbook) for a usage example. - -## 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. Install the [dependencies](../../../README.md#setup) - -3. Run the appropriate playbook: - - ```console - $ ansible-playbook -i playbooks/byo/openshift-checks/pre-install.yml - ``` - - or - - ```console - $ ansible-playbook -i playbooks/byo/openshift-checks/health.yml - ``` - - or - - ```console - $ ansible-playbook -i playbooks/byo/openshift-checks/certificate_expiry/default.yaml -v - ``` - -### The adhoc playbook - -The adhoc playbook gives flexibility to run any check or a custom group of -checks. What will be run is determined by the `openshift_checks` variable, -which, among other ways supported by Ansible, can be set on the command line -using the `-e` flag. - -For example, to run the `docker_storage` check: - -```console -$ ansible-playbook -i playbooks/byo/openshift-checks/adhoc.yml -e openshift_checks=docker_storage -``` - -To run more checks, use a comma-separated list of check names: - -```console -$ ansible-playbook -i playbooks/byo/openshift-checks/adhoc.yml -e openshift_checks=docker_storage,disk_availability -``` - -To run an entire class of checks, use the name of a check group tag, prefixed by `@`. This will run all checks tagged `preflight`: - -```console -$ ansible-playbook -i playbooks/byo/openshift-checks/adhoc.yml -e openshift_checks=@preflight -``` - -It is valid to specify multiple check tags and individual check names together -in a comma-separated list. - -To list all of the available checks and tags, run the adhoc playbook without -setting the `openshift_checks` variable: - -```console -$ ansible-playbook -i playbooks/byo/openshift-checks/adhoc.yml -``` - -## Running in a container - -This repository is built into a Docker image including Ansible so that it can -be run anywhere Docker is available, without the need to manually install dependencies. -Instructions for doing so may be found [in the README](../../../README_CONTAINER_IMAGE.md). -- cgit v1.2.3
