Postgres on Kubernetes for the Reluctant DBA
Talkat Data on Kubernetes Day Europe 2025 · on Tuesday, 2025-04-01· at 09:10· Level 1 | Hall Entrance N10 | Room E·
summary
Kubernetes already runs mission-critical multi-terabyte databases in production and the Data on Kubernetes report cites 70% running stateful workloads in 2022 and declares databases the number one workload in 2024. Operators (for example the Crunchy Data Postgres operator) use StatefulSets, PersistentVolumes, sidecars and control loops to automate HA, replication, backups, restores, upgrades and monitoring (Prometheus/Grafana). Start small — lift-and-shift can fail — and expect existing DBA skills to focus on architecture and performance while operators handle repeatable operational work.
