Create a CFS Session with Dynamic Inventory

A Configuration Framework Service (CFS) session using dynamic inventory is used to configure live nodes. To create a CFS session using the default dynamic inventory, simply provide a session name and the name of the configuration to apply:

ncn# cray cfs sessions create --name example \
--configuration-name configurations-example
{
  "ansible": {
    "config": "cfs-default-ansible-cfg",
    "limit": "",
    "verbosity": 0
  },
  "configuration": {
    "limit": "",
    "name": "configurations-example"
  },
  "name": "example",
  "status": {
    "artifacts": [],
    "session": {
      "status": "pending",
      "succeeded": "none"
    }
  },
  "tags": {},
  "target": {
    "definition": "dynamic",
    "groups": null
  }
}

Add the --target-definition dynamic parameter to the create command to explicitly define the inventory type to be dynamic. This will enable CFS to provide the Ansible host groups via its dynamic inventory. The individual Ansible playbooks specified in the configuration layers will decide which hosts and/or groups will have configuration applied to them.
