How to Install Ansible | How to Setup Master & Worker Server

Ansible

Ansible is an open-source automation tool used for configuration management, application deployment, and task automation. It is widely used due to its simplicity, flexibility, and power.

Ease of Use

• Agentless: Unlike other tools like Puppet or Chef, Ansible does not require any agent installation on managed nodes. It uses SSH for communication, simplifying management.
• Simple Configuration: Uses YAML for writing playbooks, which is easy to read and understand, even for non-programmers
• Minimal Dependencies: Ansible requires only Python installed on the target machine.

Use Cases for Ansible

• Server Provisioning: Automating the setup of servers.
• Application Deployment: Deploying and managing software across systems.
• Configuration Management: Ensuring systems stay in the desired state.
• Continuous Delivery (CD): Automating workflows in CI/CD pipelines.
• Orchestration: Managing complex workflows and interdependent systems.
