Function http_backoff 

pub fn http_backoff() -> ExponentialBackoff

Create exponential backoff configuration for HTTP API retries.

HTTP API calls (e.g., bindcar sidecar) use faster retry cycles than Kubernetes API since they target local/nearby services that should fail fast.

Configuration

• Initial interval: 50ms
• Max interval: 10 seconds
• Max elapsed time: 2 minutes total
• Multiplier: 2.0 (exponential growth)
• Randomization: ±10% (prevents thundering herd)

Retry Schedule

With these settings, retries occur at approximately:

1. 50ms
2. 100ms
3. 200ms
4. 400ms
5. 800ms
6. 1.6s
7. 3.2s
8. 6.4s
9. 10s (capped at max interval) 10-12. 10s intervals until 2 minutes elapsed

Returns

Configured ExponentialBackoff instance
