Hi, we have node app running on Kubernetes that needs to make Egress comms to two different hosts.
One is on the web (login.microsoftonline.com) and needs to go via a Squid proxy.
Other requests can just go via an Egress Gateway which we have set up.
I found this which details how to integrate with a proxy: https://istio.io/latest/docs/tasks/traffic-management/egress/http-proxy/
What that does (correct me if i’m wrong) is exposes the proxy to the container, so that the app can connect to the proxy e.g. via curl
HTTPS_PROXY=$PROXY_IP:$PROXY_PORT curl https://login.microsoftonline.com
Unfortunately though we are using a Microsoft library that requires access to login.microsoftonline.com, but does not let us configure it to use a proxy… As a result I was hoping I could do this proxying at infrastructure level.
Is there anyway that we could configure Istio to conditionally route traffic via a proxy without us having to explicitly use it in application code? e.g.
- If Host = microsoftonline -> proxy the request via SQUID
- if Host != microsoftonline -> route the request as normal
Many thanks in advance,
