One way to support multiple gateways would have been to add support for specifying them in the existing custom resource. privacy statement. You can work around this problem for simple tests and demos as follows: Use a wildcard * value for the host in the Gateway All DNS hosting services basically work the same way, whether you chose Azure, AWS, GCP, or another third party provider. We have three options. Make sure Although Istio can be configured to supportKubernetes Ingress Resources, a better approach would be to use Istios custom resources (Gateway,VirtualService). Deploy a Custom Ingress Gateway Using Cert-Manager. because you configure the requested host properly and DNS resolvable. Accordingly, an ingress gateway serves as the entry point for all services running within the mesh. In order to deploy the ingress gateway as a daemonset, i followed the advice in this link: Using JsonPatch in K8sObjectOverlay Config In general, you should manually set an external hostname that points to these addresses, but for demo purposes you can usexip.io, which is a domain name that provides wildcard DNS for any IP address.
