Ansible provides the flexibility to extend its functionality by using custom plugins. By creating plugins in a specific directory structure and implementing the required methods and attributes, you can add new features or modify existing ones. This guide explains the steps to extend Ansible with plugins, empowering you to tailor your deployment workflow according to your specific needs.
Securing Ansible: Best Practices
Secure SSH Configuration:
- Disable root login.
- Enforce strong passwords or key-based authentication.
- Limit the number of failed login attempts.
Use Secure Communication Channels:
- Encrypt communication with SSL or TLS.
- Configure Ansible to use HTTPS instead of HTTP.
Limit Access to the Control Node:
- Grant access only to trusted individuals.
- Use strong passwords or key-based authentication.
Protect Sensitive Data:
- Use Ansible's vault feature to encrypt and manage sensitive information, like passwords and API keys.
Keep Ansible Control Node Updated:
- Regularly update Ansible control node with security patches.
Implement Firewall Rules:
- Configure firewalls to allow necessary traffic and block unneeded ports or protocols.
Enable Logging and Monitoring:
- Monitor Ansible activities for unauthorized access attempts or unusual activities.
Follow Server Hardening Practices:
- Apply general server hardening practices to control and managed nodes, like disabling unnecessary services, implementing intrusion detection systems, and auditing logs.
By following these best practices, you can enhance the security of your Ansible infrastructure, safeguard sensitive data, and prevent unauthorized access.
