Is there away to enable HSTS HTTP Strict Transport Security for envoy gateway

[davem-git]

I'm looking to replace nginx ingress with envoy-gateway. I ran my site through ssl labs. While I got an A with envoy-gateway. I got an A+ with nginx. From what I can tell the only difference is the HSTS setting is called out on the NGINX one and not the envoy-gateway.

hey @davem-git can you try setting the header using this filter https://gateway-api.sigs.k8s.io/reference/spec/#gateway.networking.k8s.io/v1.HTTPHeaderFilter ?

Thanks for the example @mazzy89 . The only remaining question I have is, filters seems to be something you set for each individual HTTPRoute, but how can I set this globally at gateway level? So I don't have to set this in every HttpRoute

[mazzy89]

This a good question that you can find out. Let me know if you find it.

although not designed to apply filters globally, you could use earlyRequestHeaders (will be part of the next v1.2 release, available on latest) https://gateway.envoyproxy.io/latest/tasks/traffic/http-request-headers/#early-header-modification

[evanrappe]

To return this header to the client as HSTS requires this needs to be a response header, not a request header... Any similar early-header functionality coming for the response side of things?

[arkodg]

ah my bad, misread that, yeah for response header, @mazzy89's suggestion is the only way thats supported today

[davem-git]

Sorry I missed this. I'm not too familiar with the filters. I'll see if I can figure out how to set this
