Pod Startup Time Optimization

Slow pod startup hurts everything. The optimisations.

Image

Smaller images = faster pulls.

Multi-stage builds; only runtime layers.

Init

Lighter init containers. Parallel where possible.

Don't serialise.

Warm-up

Readiness probe doesn't pass until app is ready to serve.

Includes cache warming.
