Summary
In this chapter, we delved into key strategies for ensuring the resilience of Kubernetes clusters. We covered the following topics:
- Backup strategies: First, we explored full, incremental, differential, and application-level backups, each designed to optimize storage and recovery speed. We also emphasized the importance of backing up resources beyond etcd, including PVs, ConfigMaps, Secrets, CRDs, and application configurations.
- Backup tools and best practices: Then, we introduced tools such as Velero, Kasten K10, and Stash, which streamline Kubernetes-specific backup processes. Best practices for effective backup management include automation, encryption, regular testing, retention policies, and documentation to ensure data protection and recovery efficiency.
- Cluster maintenance: Next, we highlighted best practices for ongoing maintenance, such as using namespaces for resource organization, implementing health checks, and adhering to the principle of...
