- Runbook management: Rundeck CE allows users to create, edit, and manage runbooks, which are collections of scripts and commands that can be executed in a specific order.
- Workflow automation: Rundeck CE provides a web-based interface for defining and executing workflows, making it easier to automate repetitive tasks and manage complex systems.

How to Build Reliable Runbooks with Rundeck CE
Step 1: Plan Your Workflow
Before creating a runbook, it’s essential to plan your workflow carefully. Identify the tasks that need to be automated and the order in which they should be executed. Consider any dependencies or prerequisites that may affect the workflow.
Step 2: Create a New Runbook
Once you have planned your workflow, create a new runbook in Rundeck CE. Give the runbook a descriptive name and add a brief description of what it does.
Step 3: Add Nodes and Commands
Add nodes to the runbook, which represent the machines that will execute the commands. Then, add commands to the runbook, which are the specific actions that will be executed on each node.
Step 4: Configure Offline Copies and Repositories
Configure offline copies and repositories for the runbook, which will allow you to manage and track changes to the workflow.
Step 5: Test and Refine the Runbook
Test the runbook thoroughly to ensure that it works as expected. Refine the runbook as needed to fix any errors or issues that arise.
Automation Workflow with Snapshots and Restore Points
What are Snapshots and Restore Points?
Snapshots and restore points are features in Rundeck CE that allow you to capture the state of a runbook at a particular point in time. Snapshots create a copy of the runbook, while restore points allow you to roll back to a previous version of the runbook.
How to Use Snapshots and Restore Points
To use snapshots and restore points, follow these steps:
- Create a snapshot of the runbook before making any changes.
- Make changes to the runbook as needed.
- Create a restore point after making changes.
- If something goes wrong, roll back to a previous version of the runbook using the restore point.
