Ansible Module not found

What is Ansible Module not found

Understanding Ansible and Its Purpose

Ansible is an open-source automation tool used for configuration management, application deployment, and task automation. It allows IT administrators to automate their daily tasks and manage complex deployments with ease. Ansible uses a simple, human-readable language called YAML to describe automation jobs, which makes it accessible to both developers and system administrators.

Identifying the Symptom: Module Not Found

One common issue that users encounter when working with Ansible is the 'Module not found' error. This error occurs when Ansible is unable to locate a specified module during the execution of a playbook. The error message typically looks like this:

ERROR! no action detected in task. This often indicates a misspelled module name, or incorrect module path.

Common Scenarios

Misspelled module name in the playbook. Module not installed in the Ansible environment. Incorrect module path specified.

Explaining the Issue: Why Modules Aren't Found

Ansible relies on modules to perform tasks. These modules are essentially small programs that Ansible executes on your behalf. If Ansible cannot find a module, it means that the module is either not installed, not available in the current environment, or there is a typo in the module name.

Checking Module Availability

To check if a module is available, you can use the following command:

ansible-doc -l | grep <module_name>

This command lists all available modules and filters them by the specified module name.

Steps to Fix the 'Module Not Found' Issue

To resolve the 'Module not found' error, follow these steps:

1. Verify the Module Name

Ensure that the module name is spelled correctly in your playbook. Even a small typo can cause Ansible to fail to locate the module.

2. Install the Required Module

If the module is not installed, you can install it using Ansible Galaxy or pip, depending on the module type. For example, to install a collection from Ansible Galaxy, use:

ansible-galaxy collection install <collection_name>

For Python-based modules, you might need to use pip:

pip install <module_name>

3. Check the Module Path

If you are using a custom module, ensure that the module path is correctly specified in your playbook or Ansible configuration. You can set the module path in your ansible.cfg file:

[defaults]module_path = /path/to/custom/modules
