I seem to be able to query hostvars for a particular host from the command
line and get at the inventory variables
but I haven't figured out how to do this in a playbook. Might it be from
hostvars being lazily loaded - or my lack of
understanding how to access hostvars inventory variables successfully (or
both).
I've search and haven't found anything quite this specific - or actually
simple (just give me the inventory vars for this host via hostvars).
thx

As an example, this works:
$ ansible prtmpftp -m debug -a "var=tags"
prtmpftp | SUCCESS => {
"tags": {
"Veeam_Backup": [
"Linux_Production_Servers"
]
}
}
I'm trying to do this:
---
# tasks file for is-veeam-backup
- name: inventory_hostname
debug:
var: inventory_hostname
- name: show tags
debug:
var: tags
- name: show tags
debug:
var: hostvars[inventory_hostname]
My aim is to do something special if a specific VMware tag and/or tag
category exists.
With this in _meta for the sample host (in my inventory.json from a
vmware_inventory.py run):
"prtmpftp": {
"ansible_ssh_host": "prtmpftp",
"name": "prtmpftp",
"parent": {
"name": "Services",
"parent": {
"name": "Production",
"parent": {
"name": "Unix"
}
}
},
"tags": {
"Veeam_Backup": [
"Linux_Production_Servers"
]
},
"ansible_uuid": "d930e98b-e272-40ca-af60-34cfd946d917",
"runtime": {
"powerstate": "poweredOn"
},
"config": {
"name": "prtmpftp",
"template": false,
"uuid": "421c76a6-4f0e-441d-e6c5-13cafddbe1c9"
},
"ansible_host": "prtmpftp",
"guest": {
"guestid": "centos6_64Guest",
"guestfamily": "linuxGuest",
"gueststate": "running",
"hostname": "prtmpftp"
}
},
I get this from the playbook output:
$ ansible-playbook -i prtmpftp, is-veeam-backup.yml | more
