How to set-up custom domain name in Azure Container Instance

Question

I own a domain name with cloudflare nameservers. I've set up an Azure Container Instance with a running container hosted in Docker-Hub container registry. When i created the container instance i specified dns-name-label in azure's namespace, but i want to point my custom domain to this running container instead of the azure's one.

I've searching in Azure Docs for a way to point my custom domain name to this running container in ACI, but i didn't found any information about this configuration in Azure Container Instances. I did found some information regarding custom domains for blob storages, or cloud services, but none of those applied to ACI, as the custom domain setting doesn't appear in my ACI dashboard, neither in Azure CLI help commands.

Any information will be appreciated. I hope there is a solution to this that doesn't involve switching my NS to Azure's as cloudlflare is working just fine.

As for as I know, ACI exposes the DNS name using a dns-name-label in azure's namespace. The FQDN like customlabel.azureregion.azurecontainer.io. is provided by Azure DNS service. Unfortunately, there is no way to directly set the custom domain for ACI, but you could create a CNAME record in your DNS provider to redirect your subdomain like www.example.com to this FQDN. If so, you can access your ACI via subdomain www.example.com.
