It feels like there should be a cleaner way to get the non-empty
|Partitions|, but I’m no |jq| guru. This was a fun one.
I put this into a shell script just because it’s easier to make tweaks
while testing. It should work as a one-liner if that suites you better.
|#!/bin/bash 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] }' |
On my system, this produces the following output:
|{ "hostname": "tango", "Disks": { "dm-0": "475.34 GB", "nvme0n1":
"476.94 GB", "zram0": "8.00 GB" }, "Partitions": { "nvme0n1p1": "600.00
MB", "nvme0n1p2": "1.00 GB", "nvme0n1p3": "475.35 GB" }, "Mounts": [
"/", "/home", "/boot", "/boot/efi" ] } |

Is anyone good with ./JQ?
I'm trying to pull out data from the setup output from Ansible. I can
do most of what I need to but I'm stuck on something that is probably
quite simple.
I'm trying to generate a list of hosts including disks + sizes and
partitions + sizes AND mount points.
I can get the first two quite easily like this (this should work on
any server running on localhost) - I need the sed to format the json
correctly:
$ 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) }'
{
"hostname": "ip-172-31-16-55",
"Disks": {
"xvda": "10.00 GB"
},
"Partitions": {
"xvda1": "1.00 GB",
"xvda2": "9.00 GB"
}
}
(formatting is a little off with copy and paste)
Now if I want to collect mount points I can do it like this:
$ ansible localhost -m setup | sed '1 s/^.*$/{/' | jq -r
'.ansible_facts.ansible_mounts[].mount'
/
/boot
But because the mount information is an array (I think?) i need to map
it to get it to work? I'd like to get the results in the same list as
the one above but when i add it in it works, but it gives me a new
list for every mount point instead of just one list!
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),
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": "/"
}
{
"hostname": "ip-172-31-16-55",
"Disks": {
"xvda": "10.00 GB"
},
"Partitions": {
"xvda1": "1.00 GB",
"xvda2": "9.00 GB"
},
"Mounts": "/boot"
}
BUT, this is what I'm trying to get:
{
"hostname": "ip-172-31-16-55",
"Disks": {
"xvda": "10.00 GB"
},
"Partitions": {
"xvda1": "1.00 GB",
"xvda2": "9.00 GB"
},
"Mounts": "/"
"Mounts": "/boot"
}
}
or even a "," separated list on one line?
},
"Mounts": "/", "/boot"
}
I think I can't see the wood for the trees now and a little nudge
would be greatly appreciated.
Thanks
