Did you compare this vs passing --copt=-Os to bazel? envoy_copts doesn't apply to dependencies but CLI copt is. So I think --copt=-Os may produce smaller binary.

Using I left the option for compiling just Envoy in case somebody wants to do that. Let me know if you think I should rip it out. |
I would just rip it out. Can you also document this new stuff in https://github.com/envoyproxy/envoy/blob/master/bazel/README.md? Thank you! /wait |
Yeah, I think you can rip it out and add a config to |
