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.)

An option would be to

  • put the rpm in any_path
  • link any_path to /ansible/playbook/rpms
  • use src: rpms/zookeeper-3.4.13-1.x86_64.rpm

  • Actually this will not work because: 1. you cannot create hard links to directories (or at least I did not find a way to do it). 2. Soft links are not properly visible inside Docker container because the original linked directory (`any_path`) is not visible inside the container. – Gabriel Petrovay Feb 17 '19 at 20:31

You could use a lookup with a list of paths and the first_found query: 

- name: install ZooKeeper rpm package
  yum:
    name: "{{ item }}/zookeeper-3.4.13-1.x86_64.rpm"
    state: present
  loop: "{{ query('first_found', { 'paths': mypaths}) }}"
  vars:
    mypaths: ['/tmp', '/opt/other_location/somedir/', '/rpms']
