How can I automate configuration validation in my projects?

You can automate configuration validation by using tools like Ansible, Terraform, or custom scripts that check your configurations against predefined rules.

What are the benefits of automating this process?

Automating configuration validation reduces human error, saves time, and ensures consistency across environments.

Can you give me an example of a script for validation?

Sure! Here's a simple Python script that checks if a configuration file has the required keys:

import json

required_keys = ['host', 'port', 'username']

with open('config.json') as f:
    config = json.load(f)

for key in required_keys:
    if key not in config:
        print(f'Missing key: {key}')
