Hi,

Thank you for the prompt reply.

We are currently in the process of assessing the migration of our existing Istio virtual services to the Gateway API, utilizing Google Cloud's GKE-L7-GXLB. Within our current Istio setup, we employ path-based routing with regular expressions.

In attempting to reproduce this functionality using `httproute` and the `path match` feature with Regular Expressions, as specified in the CRD[1] for `httproute`, we encountered the following problem.

HTTPRoute "images-httproute" is misconfigured, err: unsupported path match type "RegularExpression"

The feature seems to still miss. Will it ever be implemented?

Ay,

We're in the same situation where we need RegularExpression feature for our Gateway API routes in GKE.

Large project with several clusters here, we had to ditch using GKE Gateway due to something simple as "Wildcards are not supported"

Hi Team

Could you please suggest if this has been implemented or ongoing.. we also need the same while implementing MCG in our environment.

My company needs RegularExpression support as well in HTTPRoute. Or a way to use PathPrefix with a simpler glob wildcard or replacement params.

Until GKE has this feature, this can be one of the possible solutions -

Nginx Reverse Proxy Server can be placed between HTTPRoute and the application services, then in Nginx you can configure regex accordingly,

Here is a blog written by me explaining how it can be done

https://blog.thecloudside.com/solving-gkes-regex-path-matching-limitation-with-nginx-reverse-proxy-server-in-a-multicluster-gke-a521fd97e14c

This is for MultiCluster GKE, But for Single Cluster as well, this implementation can be referred.
