Tikv: `make docker` doesn't work on MacOS

[oraluben]

Bug Report

I was trying to build a docker image for tikv on my mac, and it shows some error message as below.
I briefly searched among the issues and didn't find some existing issues, so I'm not sure if this is intended or not.

What version of TiKV are you using?

not relevant

What operating system and CPU are you using?

MacOS

Steps to reproduce

run make docker

What did you expect?

command succeeds without error

What did happened?

$ make docker
bash ./scripts/gen-dockerfile.sh | docker build -t pingcap/tikv -f - .
sed: illegal option -- r
...

I had this issue the other day. Whichever version of sed ships with MacOS is not the version anticipated by this script. Try installing gnu-sed via:
brew install gnu-sed
and make sure that /usr/local/opt/gnu-sed/libexec/gnubin appears before wherever the default sed is in your path
