Inventory sub-tab

In this tab, it is possible to view the peers that have Peer Management enabled in a cluster. These are devices that can be selected to run a Playbook.This page lists the ansible inventories associated with the Nodegrid device. When runnning an ansible-inventory --list  command in Ansible, all the inventories are listed on the Inventory tab. For a coordinator, the peers of Cluster are automatically added to the ansible inventory.

It is possible to view what variables are in your host inventories.

1. Navigate to SYSTEM::CENTRAL MANAGEMENT::INVENTORY

   Current host inventories are displayed

2. Select the checkbox next to the host inventory

3. Click on the Show Variables button

   The variables for the selected host inventory are displayed

   Examples

   • Valid input formats:

     • Filepath: @/etc/ansible/variables/yourfilename.yml

       • WebUI, CLI and API: Only accepts valid files. File must exist and the ansible user can read.

     • Json: {"key":"value"} , '{"key":"value"}' , "{"key":"value"}"

     • yml: key=value ,"key=value key=value" , 'key=value key=value'

   • Invalid input formats:

     • Filepath: @/file_not_exist >> Cannot find or access the file.

     • Filepath: @/root_only_read >> Cannot read file.

     • Json: '{"name:json_name", "local:json_local"}' >> Invalid JSON format. Extra variable will be ignored according to Ansible’s default behavior, and variable precedence applies.

     • yml: 'name=value_name local= value_local' >> The extra variable “local” is invalid, so it will be ignored by Ansible, following its default behavior and variable precedence rules.
