How to build envoy from source code

I’m trying to build sidecar using the code from istio/proxy: The Istio proxy components. (, the command I use is make build_envoy BUILD_WITH_CONTAINER=1. However, I can’t find the location of the executable after the build ends successfully.

My doubts are:

  1. Where can I find the executable after make
  2. Is there any guidance document on building the envoy sidecar

Just as you can see, I am a beginner. Thank you for answering my question. :smiling_face_with_three_hearts:
