Before you begin
Permissions: Some processes documented in runbooks for Toolforge will need varying levels of permission to perform. Make sure you have appropriate permissions to complete your task.
What is a runbook?
A runbook is a detailed set of instructions that explain how to perform a common task or procedure, so it can be easily and accurately repeated by others. Runbooks are particularly useful for incident response operations. Creating runbooks in response to specific incidents, makes it possible for people to repeat the steps in response to similar incidents. Because they are often used to help people respond to incidents quickly, they should be easy to read and follow, consistent, and accurate.
When should you use a runbook?
A runbook should be used whenever a common task or procedure may need to be repeated by mulitple people.
Tips for building useful runbooks
- Keep them up-to-date. Revisit the instructions after each incident to make sure they are clear and accurate.
- Keep them simple. These are sets of detailed instructions, and they do not require extra history or context.
- Publish a separate runbook for each issue or incident
- Test them. Make sure the instructions are repeatable by others by asking others to follow them and provide feedback.
- Follow a template. Make sure your runbooks follow a template, so that people can find and update information easily.
Cloud VPS runbook templates
Instructions for each issue or alert should have its own page in order to reduce unnecessary information. You can see an example here with the issue Check for VMs leaked by the nova-fullstack test. Note that the page addresses one issue only.
You can find a template/outline for creating runbooks here: Portal:Cloud_VPS/Admin/Runbooks/Runbook_template
