Comment 1 Andrew McDermott 2020-05-20 14:01:39 UTC

https://github.com/openshift/cluster-ingress-operator/pull/401

Needs a corresponding change in openshift/router too.

Comment 4 Hongan Li 2020-06-01 03:30:41 UTC

Verified with 4.5.0-0.nightly-2020-05-30-025738 and the issue has been fixed.

After annotating the ingresscontroller with ingress.operator.openshift.io/unsupported-disable-http2="true", the Env  ROUTER_DISABLE_HTTP2=true is added to Deployment and the reencrypt route with custom cert uses HTTP1.1 now.

$ oc -n openshift-ingress-operator annotate ingresscontroller/default ingress.operator.openshift.io/unsupported-disable-http2="true"

$ oc -n openshift-ingress rsh router-default-758df89759-6v9qn
sh-4.2$ env | grep HTTP2
ROUTER_DISABLE_HTTP2=true

$ curl --resolve test-reen.example.com:443:a.b.c.d https://test-reen.example.com -k -I
HTTP/1.1 200 OK
