How does deleting pilot pods effect an already running istio-proxy container?
I was under the impression that if pilot delivers the configuration once, istio-proxy should be able to run with it even when pilot is not available.
I am running fortio in an istio enabled namespace hitting my service (ping) that returns 200OK in response.
Here’s the fortio spec:
spec:
containers:
- name: fortio
image: fortio/fortio
command: ["fortio"]
args: ["load", "-t", "3000s", "-qps", "100", "http://ping:8080/ping"]
The test runs well until I delete the pilot pods. I observed that after about a minute or 2 of deleting the pilot pods, fortio starts giving these errors:
06:40:00 E http_client.go:677> Read error &{{0xc0003d2380}} 46.19.209.189:8080 0 : read tcp 100.122.111.88:43086->46.19.209.189:8080: i/o timeout

The corresponding logs on istio-proxy on ping service say Envoy NOT ready:
* failed checking application ports. listeners="0.0.0.0:15090"
* envoy missing listener for inbound application port: 8080

What am I missing?
