Thanks for that, It was exactly what I was looking for. I was so close...
This is what I get:
$ ansible localhost -m setup | sed '1 s/^.*$/{/' | jq '.ansible_facts |
{hostname: .ansible_hostname, Disks: .ansible_devices |
with_entries(.value |= .size), Partitions: [.ansible_devices[].partitions
| with_entries(.value |= .size)] | .[] | select(length>0), Mounts:
[.ansible_mounts[].mount] }'
{
"hostname": "ip-172-31-16-55",
"Disks": {
"xvda": "10.00 GB"
},
"Partitions": {
"xvda1": "1.00 GB",
"xvda2": "9.00 GB"
},
"Mounts": [
"/",
"/boot"
]
}
