Ansible - Resolve "The ipaddr filter requires python's netaddr be installed on the ansible controller"

Updated:   |  Ansible articles

Let's say something like this is being returned.

fatal: [server1.example.com]: FAILED! => {"msg": "The ipaddr filter requires python's netaddr be installed on the ansible controller"}

 

My Ansible playbook included ansible.utils.ipaddr.

---
- hosts: all
  tasks:
  - name: create the empty all_ipv4_addresses_with_prefix list
    set_fact:
      all_ipv4_addresses_with_prefix: []

  - name: append default IPv4 address/prefix to the 'all_ipv4_addresses_with_prefix' list
    set_fact:
      all_ipv4_addresses_with_prefix: "{{ all_ipv4_addresses_before_leapping + [(ansible_eth0.ipv4.address + '/' + ansible_eth0.ipv4.netmask) | ansible.utils.ipaddr('network/prefix')] }}"
...

 

I was running my Ansible playbook in a Python virtual environment that did not include the netaddr package.

~]$ python3.10.2_virtual_env/bin/python3.10 -m pip list
Package      Version
------------ -------
ansible-core 2.16.0
cffi         1.16.0
cryptography 41.0.5
Jinja2       3.1.2
MarkupSafe   2.1.3
packaging    23.2
pip          23.3.1
pycparser    2.21
PyYAML       6.0.1
resolvelib   1.0.1
setuptools   58.1.0
wheel        0.41.3

 

I installed the netaddr package in my Python virtual environment.

~]$ python3.10.2_virtual_env/bin/python3.10 -m pip install netaddr
Installing collected packages: netaddr
Successfully installed netaddr-0.9.0

 

Validated my Python virtual environment contained the netaddr package, re-ran my Ansible playbook and no longer got the error.

~]$ python3.10.2_virtual_env/bin/python3.10 -m pip list
