Envoy: unable to initialize hot restart: unable to bind domain socket with id=0

[fabware]

I'm trying to run two envoy instance on same host and I get error message: "unable to initialize hot restart: unable to bind domain socket with id=0"

Is it by design or anything I'm missing?

In general we don't recommend running more than 1 envoy per machine (easier to operate, one source of stats, etc.) but if you want to you can use this option: https://lyft.github.io/envoy/docs/operations/cli.html#cmdoption--base-id

This will tell Envoy to use a different set of unix domain sockets so that each envoy can be hot restarted independently.

--base-id 1 solved my problem, thanks for your help and suggestion.

It would be nice to add the above suggestion along with error message, this may make it easier for new comers.
