In my case I am mounting my Ansible code inside a Docker container under `/ansible/playbook/`. Under this directory you will see the `roles`, `inventories`

I would like to mount another directory that contains some RPM files.

In Ansible I have this code:

```
---
- name: copy ZooKeeper rpm file
  copy:
    src: zookeeper-3.4.13-1.x86_64.rpm
    dest: /tmp

- name: install ZooKeeper rpm package
  yum:
    name: /tmp/zookeeper-3.4.13-1.x86_64.rpm
    state: present

```

The problem is that ZooKeeper does not exist in any of the default search paths:

```
Could not find or access 'zookeeper-3.4.13-1.x86_64.rpm'
Searched in:
    /ansible/playbook/roles/kafka/files/zookeeper-3.4.13-1.x86_64.rpm
    /ansible/playbook/roles/kafka/zookeeper-3.4.13-1.x86_64.rpm
    /ansible/playbook/roles/kafka/tasks/files/zookeeper-3.4.13-1.x86_64.rpm
    /ansible/playbook/roles/kafka/tasks/zookeeper-3.4.13-1.x86_64.rpm
    /ansible/playbook/files/zookeeper-3.4.13-1.x86_64.rpm
    /ansible/playbook/zookeeper-3.4.13-1.x86_64.rpm

```

How can I add extra search paths to this list for example:

```
    /ansible/rpms/zookeeper-3.4.13-1.x86_64.rpm//

```

I don't want to hardcode absolute paths (if this works) in the Ansible code. I would like to provide something like: `ANSIBLE_EXTRA_SEARCH_PATH`.

How can I do this?

PS: I cannot create a symlink to my RPM directory inside the already mounted `/ansible/playbook` because Docker will see it and a bad link (not being able to read it, because the target directory, the one containing the RPM files is not part of the Docker container file system.)
