Effected Components
linode.cloud.instance
Expected Behavior
The simplest dynamic inventory file should work without warnings.
Actual Behavior
With the following minimal inventory file, a warning is generated to stderr by ansible-inventory (and everything else that uses the inventory).
$ ansible-inventory -i inv.linode.yaml --list>/dev/null
[WARNING]: Found variable using reserved name 'tags'.
Origin: <unknown>
tagsSteps to Reproduce
The file inv.linode.yaml is simply:
$ cat inv.linode.yaml
plugin: linode.cloud.instance
# Filter by tag
api_token: "{{ lookup('env', 'LINODE_CLI_TOKEN') }}"
compose:
ansible_host: ipv4[0]
