Site Reliability Engineers (SREs)
Designing a cluster update strategy for a production environment with strict uptime requirements
Use cases
About
The Kubernetes Engine Maintenance mind map template provides a comprehensive framework for managing GKE cluster lifecycles, covering 138 nodes of technical documentation. This cheat sheet is designed for DevOps engineers and SREs to master the balance between system stability and automated updates. It specifically details the mechanics of 'Maintenance windows' and 'Maintenance exclusions', explaining how to schedule repeating time slots for permitted maintenance or define non-repeating windows where automatic maintenance is strictly forbidden. The template serves as a technical guide for understanding how Google Cloud performs tasks on clusters, including 'auto-upgrades' to masters and nodes, and the implications of user-initiated configuration changes on internal network topology. By using this Xmind template, teams can visualize the impact of security patches, mandatory upgrades, and the automated repair functionality that ensures cluster health even outside of defined windows.

Frequently asked questions
A maintenance window is a repeating time slot where automatic maintenance is permitted, whereas a maintenance exclusion is a non-repeating window where maintenance is forbidden. This Kubernetes Engine Maintenance template helps visualize how these two configurations interact to provide control over cluster updates.
Yes, the template specifies that manually-initiated upgrades begin immediately and ignore any configured maintenance windows or exclusions, allowing for urgent administrative changes when necessary.
Absolutely. The template highlights that GKE reserves the right to override maintenance policies for critical security vulnerabilities, ensuring your infrastructure remains protected even if a maintenance exclusion is active.
The template notes that automated repairs on cluster masters and nodes generally ignore maintenance windows because failing to perform these repairs could result in non-functional clusters.
