setup_acm_agents
=========

This role prepare prepares agents running from an on-premise inventory (bare metal or virtualized) to be provisioned. The nodes must be reachable via Virtual Media.

Requirements
------------

* The nodes must be reachable via Virtual Media.
* Access to an OpenShift cluster with ACM and MCE operators
* Access to a valid kubeconfig file available using the `KUBECONFIG` environment variable.
* AgentServiceConfig and Provisioning configured on the host cluster

Role Variables
--------------

The following variables can be set to customize the role behavior:

### Required Variables

| Variable Name | Type | Required | Default Value | Description
| --------------------------------------- | --------- | -------- | -------------------------------------- | --------------
| setup_acm_agents_inventory | List | Yes | [] | Inventory of bare metal hosts. It must contain the BMC credentials. See [Usage examples](#usage-examples)
| setup_acm_agents_infraenv_name | String | Yes | | Target the infrastructure environment
| setup_acm_agents_inject_dns | Boolean | No | false | Enables custom DNS injection. Set to true to pass custom DNS configuration; false disables it
| setup_acm_agents_inject_dns_nameserver | String | No | | Specifies the custom DNS server(s) to use when `setup_acm_agent_inject_dns` is set to true
| setup_acm_agents_location_label | String | No | "" | Location label
| setup_acm_agents_no_log | Boolean | No | `false` | Role's logging configuration
