Create Inventory via API

1. Generate token: Admin → User details → Tokens → Add (Scope: Write)

2. Get inventory ID:

curl -sH "Authorization: Bearer YOUR_TOKEN" \
  -X GET https://<awx_server>/api/v2/inventories/ | \
  jq '.results[] | select(.name=="vms") | .id'

3. Add hosts:

# Single host
curl -X POST "https://<awx_server>/api/v2/inventories/2/hosts/" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -d '{"name": "10.66.10.5"}'

# Multiple hosts from Kubernetes VMs
for ip in $(kubectl get -A vm -o json | jq '.items[].status.ipAddress' -r); do
  curl -X POST "https://<awx_server>/api/v2/inventories/2/hosts/" \
    -H "Content-Type: application/json" \
    -H "Authorization: Bearer YOUR_TOKEN" \
    -d '{"name": "'${ip}'"}'
done
