Allow Cloudflare traffic only to Azure Container Apps

Hi, since Azure Container Apps ingress filtering is only able to accept IPv4 addresses as whitelist, I’m looking for an alternative solution to allow traffic exclusively from Cloudflare network to ACA. With this limitation of ACA, CF’s IPv6 ranges can’t be added to the whitelist, so most probably some legit requests from CF would be rejected as their source IP isn’t on the whitelist. Anyone have any experience with this?

Well, if you create an A record for your.domain.com pointing to ACA, then Cloudflare will only make connections via IPv4 So you shouldn't need to worry about IPv6 at all
