Adds a flag called
insecure-metrics-service-skip-tls-verify
to both the adapter and operator to disable TLS on the GRPC connection between the two services. This flag is defaulted tofalse
, i.e the existing behavior.I am adding this change because we use the Envoy service mesh for TLS so we need to disable TLS in our service code in order for our proxy to handle the rest.
I could not find a specific config flag test but since I wrote this in a way that if left unset, you get existing behavior, I expect any issues to show up on the e2e tests.
I did validate in our cluster and I have the expected behavior of being able to disable TLS on both client and server and having the two connect over envoy.
