Helm Chart Webhook Provider port mismatch

[Skaronator]

What happened:

External-dns uses a hardcoded port (8888) for Webhook providers:

external-dns/main.go

Line 371 in b336c52

webhookapi.StartHTTPApi(p, nil, cfg.WebhookProviderReadTimeout, cfg.WebhookProviderWriteTimeout, "127.0.0.1:8888")

However, the Helm chart defines a liveness probe for the webhook provider on port 8080:

external-dns/charts/external-dns/templates/deployment.yaml

Line 162 in b336c52

containerPort: 8080

This inconsistency results in a CrashLoopBackOff, as the health check is looking for the service on port 8080, while the actual service runs on port 8888.

What you expected to happen:

Both ports are hardcoded and should be aligned to avoid this issue.

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?:

Environment:

• External-DNS version (use external-dns --version): external-dns-helm-chart-1.15.0
• DNS provider: webhook
