I am using istioingress gateway. How can I redirect non-www traffic to www?
apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
name: my-gateway
namespace: some-config-namespace
spec:
selector:
app: my-gateway-controller
servers:
- port:
number: 80
name: http
protocol: HTTP
hosts:
- uk.bookinfo.com
- eu.bookinfo.com
- www.uk.bookinfo.com
- www.eu.bookinfo.com
tls:
httpsRedirect: true # sends 301 redirect for http requests
- port:
number: 443
name: https-443
protocol: HTTPS
hosts:
- uk.bookinfo.com
- eu.bookinfo.com
- www.uk.bookinfo.com
- www.eu.bookinfo.com
tls:
mode: SIMPLE # enables HTTPS on this port
serverCertificate: /etc/certs/servercert.pem
privateKey: /etc/certs/privatekey.pemCurrently, I am able to access the website using both endpoints. But, I want to redirect all traffic from non-www to www.
Have you tried redirect feature of Istio?
apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
name: server-vs
spec:
hosts:
- mysite.com
gateways:
- my-gateway
http:
- match:
- uri:
exact: /
redirect:
uri: /
authority: www.mysite.comAlso you could have done the redirection at DNS level. But I think some domain providers don't support it. Godaddy, for example, does.
Istio Gateway receives the traffic, and the routing from there will be handled by VirtualService configuration. For your non-www to www traffic routing, the same question was raised in Istio discussion forum, so that may be of your help.

As to getting all the traffic, you may want to use a wildcard in the hosts definition in the Gateway configuration (ref: https://istio.io/docs/reference/config/networking/gateway/#Server).
