Init Containers Best Practices
Init containers run before main containers. The patterns that work.
Live workflow · 3 working · 1 queuedLive
Signal · gather Working
Decide · pick action Working
Apply · with verify Working
Learn · update playbook Queued
When
Pre-flight checks. Wait for dependencies. Generate config.
Specific tasks; not generic startup.
Design
Each init has a single responsibility.
Fail fast; don't wait forever.

Heavy init containers. Long startup masks readiness issues.
Keep them light.
