I have a rather strange problem with an Ansible playbook.
This bug only occurs in my Docker container with Debian:9.9-slim and I've tried with different Docker distributions but it doesn't change the problem.
The errors I'm showing you may have line inconsistencies. This is because I have commented on a whole part of my playbook and I am showing you the playbook without the comments for reasons of professional secrecy.
So, my application is a flask-restplus API that launches playbooks via ansible-runner. In this case, ansible provides a dictionary called "device" via extravars:
{
"admin_password": "password",
"admin_user": "admin",
"dns1_server_ip": "0.0.0.0",
"equipement_name": "DEVICE_NAME",
"hostname": "ANSIBLE_BUG",
"ip": "0.0.0.0",
"port": 80
}
This is my playbook:
- hosts: localhost
connection: local
any_errors_fatal: no
tasks:
- debug:
msg: '{{ device }}'
- debug:
msg: '{{ device["ip"] }}'
I've also try this way:
- hosts: localhost
connection: local
any_errors_fatal: no
tasks:
- debug:
msg: '{{ device }}'
- debug:
msg: '{{ device.ip }}'
And I've this error:
deploy okay [WARNING]: Unable to parse /etc/ansible/hosts as an inventory source
[WARNING]: No inventory was parsed, only implicit localhost is available
[WARNING]: provided hosts list is empty, only localhost is available. Note
that the implicit localhost does not match 'all'

Someone on an other post suggest me to use "from_json" like this:
- debug:
msg: '{{ device | from_json }}'
- debug:
msg: '{{ (device | from_json)["ip"] }}'
And i've got a new error:

I tried commenting on the first msg debug, but I have the same error.
So I've been trying to iterate on device:
- debug:
msg: '{{ item }}'
with_dict: "{{ device }}"
And it's work:
deploy okay [WARNING]: Unable to parse /etc/ansible/hosts as an inventory source
[WARNING]: No inventory was parsed, only implicit localhost is available
[WARNING]: provided hosts list is empty, only localhost is available. Note
that the implicit localhost does not match 'all'

I conclude device is therefore a dictionary.
But I wanted to make sure, so I created a variable to which I assign "device":
- set_fact:
device_dict: '{{ device }}'
- debug:
msg: '{{ device_dict }}'
- debug:
msg: '{{ device_dict["ip"] }}'
And it's work:
deploy okay [WARNING]: Unable to parse /etc/ansible/hosts as an inventory source
[WARNING]: No inventory was parsed, only implicit localhost is available
[WARNING]: provided hosts list is empty, only localhost is available. Note
that the implicit localhost does not match 'all'

As a reminder, this playbook is used in a Docker container. Except if I run it on the host machine running Debian 9, my initial playbook works perfectly.
I could use the last solution exposed above, but this would make me modify a large number of playbooks containing even a large number of tasks, so I will only do this as a last resort.
If you have any questions don't hesitate :)
Do you have any idea what the problem might be?
