Flyway + Kubernetes: Rolling Back Failed DB Migrations

When a database migration fails mid-deploy, your Kubernetes job hooks and Flyway versioning strategy are the difference between a five-minute fix and a 2am incident.

You'll learn:

• How to structure Flyway versioned and undo migrations so a failed V3 doesn't leave your schema in a half-applied state
• Using Kubernetes init containers and Job postStart/preStop hooks to gate application rollout on migration success or failure
• Why flyway repair matters when checksums break and how to use it safely in CI pipelines
• Patterns for keeping application code and schema changes in sync across canary and blue-green deployments
• What interviewers actually want to hear when they ask about zero-downtime schema migrations at scale
