## Summary
- Increase kamaji controller memory limit from 500Mi to 512Mi
- Increase kamaji controller memory request from 100Mi to 256Mi
- Add startup probe with 60-second timeout (12 attempts × 5s periods)
- Increase readiness/liveness probe initialDelaySeconds from 5s/15s to
30s
## Problem
The kamaji controller was experiencing frequent CrashLoopBackOff due to
OOMKilled errors. Analysis showed:
- Container was being killed with exit code 137 (OOMKilled) after ~20-25
seconds of runtime
- Memory limit of 500Mi was insufficient for controller initialization
- Readiness probe was failing because it started too early (5s
initialDelay), before the controller finished leader election (~17s)
## Solution
**Memory increase:**
- Limit: 500Mi → 512Mi (based on production testing)
- Request: 100Mi → 256Mi (ensures adequate reservation)
**Startup probe:**
- Added to give controller up to 60 seconds to initialize without being
killed by liveness probe
- 12 attempts × 5s period = 60s maximum startup time
**Probe delays:**
- ReadinessProbe: 5s → 30s initialDelay (controller needs ~17s to
acquire leader lease)
- LivenessProbe: 15s → 30s initialDelay (aligned with readiness)
## Testing
Verified in production cluster:
- Controller runs stable with 0 restarts
- No more OOMKilled events
- Successfully creates kubeconfig secrets for tenant clusters
## Related Issues
Fixes tenant cluster components stuck in ContainerCreating due to
missing kubeconfig secrets (caused by crashing kamaji controller).

## Summary by CodeRabbit
* **Chores**
* Introduced automated health checks using HTTP-based probes to monitor
service status during startup, continuous operation, and readiness to
handle traffic.
* Adjusted container memory resource allocation for enhanced stability
and performance.
