Learn how to fix the "ModuleNotFoundError: No module named 'kubernetes'" issue in Ansible, even when Kubernetes is installed.
---
When working with Ansible, you might encounter a frustrating ModuleNotFoundError: No module named 'kubernetes' despite having Kubernetes installed. This error commonly appears when executing roles or tests using Molecule. Even if you've confirmed that Kubernetes is correctly installed on your system, Ansible may still not recognize the module. Here's how to troubleshoot and resolve this issue effectively.

Understanding the Error

The ModuleNotFoundError occurs when Python is unable to find the specified module (kubernetes in this case). This can be due to several reasons:

Python Path Configuration: The Kubernetes module might not be in Python's search path.

Virtual Environment: Ansible may be running in a different Python environment where Kubernetes is not installed.

Molecule Configuration: The environment Molecule runs in might be lacking the required dependencies.

Steps to Resolve the Issue

Verify Kubernetes Module Installation

First, ensure that the kubernetes package is installed in the right Python environment. Run this command to verify:

Check Python Path

Ensure that the Python interpreter used by Ansible can find the Kubernetes module. You can verify the current Python path with:

If the path does not include the directory where the Kubernetes module is installed, you might need to add it manually.

Activate Virtual Environment

If you are using a virtual environment, make sure it's activated:

After activation, run pip show kubernetes again to ensure that the module is available within the virtual environment.

Configure Molecule

Molecule might be running your tests in a different environment. Ensure that the Kubernetes module is installed in Molecule’s environment. You can add dependencies in Molecule's requirements.yml:

dependency:
name: galaxy
options:
role-file: requirements.yml
requirements: requirements.txt
