[guilhermeblanco]

external-dns to create Route53 entries for Istio Gateway.

This would be a new source in External DNS, right?

[guilhermeblanco]

@hjacobs Indeed. From what I'm diving into external-dns code, it looks like a pretty similar copy of source/ingress.go (with some modifications to pull from the proper endpoint) and an entry on source/store.go.

Awesome. We're porting our ingress to istio as we speak and will need this pretty shortly. Is there any update here? I can potentially take a stab at it, if that's helpful.

How would my domain stay on Route 53? For example: Using kops to create my clusters, would uk.bookinfo.com point to the dns name of ELB?

Could I use this integration to automatically create DNS records for Ingress resources in AWS?

@hjacobs anybody working on this ? Istio reached 1.0.0 earlier this week. Having external-dns support for the VirtualService and/or Gateway objects would be a great addition.

AFAIK there are no PRs open for that, feel free to open one (even WIP) if you wish to work on it.

[bzon]

Is there an alternative solution?

[patelpu94]

Do we know when this will be available? We need this too, we already tested the PR branch and it works as expected.

It looks like v0.5.6 includes these changes.
