I am trying to use Ansible Collection for example the nginx one.

The directory tree structure looks like this:

    ├── ansible_collections
    │   └── nginxinc
    │       └── nginx_core
    │           ├── CHANGELOG.md
.......
    │           ├── README.md
    │           └── roles
    │               ├── nginx
    │               │   ├── tasks
    │               │   │   ├── amplify
    │               │   │   ├── config
    │               │   │   ├── keys
    │               │   │   ├── main.yml
    │               │   │   ├── modules
    │               │   │   ├── opensource
    │               │   │   │   └── install-debian.yml
    │               │   │   └── unit
    ....
        ├── hosts
        └── site.yaml

the site.yaml file I wrote is:

- name: Demo
  hosts: all
  connection: local
  gather_facts: no

  tasks:
  - name: test
    include_role:
      name: nginxinc.nginx_core.nginx
      tasks_from: install-debian

I am trying to run the task install-debian from the role nginx.

I run the playbook:

ansible-playbook -i hosts site.yaml

I get this error:

ERROR! the role 'nginxinc.nginx_core.nginx' was not found.....

I need help on how I should fix the site.yaml file

If I understand correctly, you should just install the Nginx collection with the following command, as explained here:
```
ansible-galaxy collection install nginxinc.nginx_core
```
It should install it in ~/.ansible/collections/ansible_collections/nginxinc/nginx_core/. Then create a playbook following these examples and the Ansible docs:
```
---
- hosts: all
  collections:
    - nginxinc.nginx_core
  roles:
    - role: nginx
```
Finally run your playbook:
```
ansible-playbook -i hosts my_nginx_playbook.yaml
```
It’ll pick the Debian version for you if your host is Debian.

I regret to say that this is not working for me. this gives the impression that collections_paths is not used.

ansible –version

ansible 2.9.17

ansible-config view
```
[defaults]
inventory=/usr/local/ansible-admin/my_hosts
roles_path=/usr/local/galaxy-roles:./roles
collections_paths=/usr/local/ansible_collections
log_path=./ansible.log
```
the collections are installed in the /usr/local/ansible_collections folder:

tree -L 2 /usr/local/ansible_collections/nginxinc/
```
/usr/local/ansible_collections/nginxinc/
└── nginx_core
    ├── CHANGELOG.md
    ├── CODE_OF_CONDUCT.md
    ├── CONTRIBUTING.md
    ├── docs
    ├── FILES.json
    ├── LICENSE
    ├── MANIFEST.json
    ├── playbooks
    ├── plugins
    ├── README.md
    └── roles
```
here is the very basic content of the playbook:

cat playbooks/nginx_core.yml
```
- name: Test collection ansible with nginxinc
 hosts: "{{ target }}"
  collections:
    - nginxinc.nginx_core
  tasks:
    - import_role:
        name: nginx
```
we get the following error message when it is launched:

ansible-playbook playbooks/nginx_core.yml –extra-vars target=myvm.mydomain.org
```
ERROR! the role 'nginx' was not found in nginxinc.nginx_core:ansible.legacy:/usr/local/ansible-admin/playbooks/roles:/usr/local/galaxy-roles:/usr/local/ansible-admin/roles:/usr/local/ansible-admin/playbooks
```
it doesn’t find the role in the collections, and worse, it doesn’t say that it looked in the collections_path…

But here is a solution that works, but it is very very ugly: add the nginx role of the collection in roles_path!
```
roles_path=/usr/local/galaxy-roles:./roles:/usr/local/ansible_collections/nginxinc/nginx_core/roles
```
warning: this is obviously a misuse of the ansible collections!

any help would be appreciated.
