This is a simple toy setup for running envoy within VPP attached with the VCL
This testing was done in a single node cluster, with 20.0.0.1/24 being the node
address, connected to another node with 20.0.0.2/24
Envoy is configured in both cases to listen on podID:10001 and proxy to 20.0.0.2:80
Service addresses are also configured
In order for this to work, we need to remove sNAT (either globally, or just for our peer address)
set cnat snat-policy prefix 20.0.0.2/32
Then create two envoy pods (with and without VCL)
test.sh up envoyTo start envoy
# with VCL
kubectl exec -it -n envoy envoy-vcl -- taskset -c 0-3 envoy -c /etc/envoy/envoyvcl.yaml --concurrency 4
# with linux
kubectl exec -it -n envoy envoy-linux -- taskset -c 0-3 envoy -c /etc/envoy/envoy.yaml --concurrency 4
