External-dns: Route53 DNS records not deleted

[anarwal]

I am using 0.5.18 tag of external-dns (registry.opensource.zalan.do/teapot/external-dns:0.5.18) with AWS route53 and created new record with kube's ingress resources using following:

  annotations:
    kubernetes.io/ingress.class: alb
    alb.ingress.kubernetes.io/scheme: internet-facing
    alb.ingress.kubernetes.io/certificate-arn: ${route53_certificate}
    alb.ingress.kubernetes.io/ssl-policy: ELBSecurityPolicy-2016-08
    external-dns.alpha.kubernetes.io/hostname: ${somedns_com}

if I go ahead and update this ingress resource for dns entry or delete the ingress resource, it doesn't delete the record from Record53. I thought they entry should be deleted by default if ingress resource gets deleted.

Please check the container policy argument on your external-dns pod to be set to sync. I think the default value is upsert-only, which will prevent external-dns from deleting any DNS records.

Yep, it was set to upsert-only, I will update it to sync. Thanks for the response.
