HTTPProxy supports routing traffic to
ExternalName service types.
Contour looks at the
spec.externalName field of the service and configures the route to use that DNS name instead of utilizing EDS.
There’s nothing specific in the HTTPProxy object that needs to be configured other than referencing a service of type
HTTPProxy supports the
requestHeadersPolicy field to rewrite the
Host header after first handling a request and before proxying to an upstream service.
This field can be used to ensure that the forwarded HTTP request contains the hostname that the external resource is expecting.
Note: The ports are required to be specified.
# httpproxy-externalname.yaml apiVersion: v1 kind: Service metadata: labels: run: externaldns name: externaldns namespace: default spec: externalName: foo-basic.bar.com ports: - name: http port: 80 protocol: TCP targetPort: 80 type: ExternalName
To proxy to another resource outside the cluster (e.g. A hosted object store bucket for example), configure that external resource in a service type
Then define a
requestHeadersPolicy which replaces the
Host header with the value of the external name service defined previously.
Finally, if the upstream service is served over TLS, set the
protocol field on the service to
tls or annotate the external name service with:
projectcontour.io/upstream-protocol.tls: 443,https, assuming your service had a port 443 and name
