How to build out docker engine arm binary?

I see this, from here I can download docker daemon & docker client for arm64 version which works.

$ ls | xargs file

Then, I want to know how above binary comes out, I see this, it's a good article which I successfully build out binary for x86-64 with make static DOCKER_BUILD_PKGS=static-linux with the source here

But, I need arm version, so I tried next 2 methods:

  1. make static DOCKER_BUILD_PKGS="static-linux cross-arm"

  2. GOOS=linux GOARCH=arm64 make static DOCKER_BUILD_PKGS=static-linux

Above 2 methods both work to build out docker client with arm version, but the docker daemon still x86-64 version, see next:

orange@orange:~/docker-ce/components/packaging/static/build/linux/docker$ ls | xargs file

So, what I am doing wrong, how could I get arm version for dockerd?

From the source code we can see the cross-arm option does the client only.

https://github.com/docker/docker-ce-packaging/blob/753db553b261ffd84e2d452a0eff1aade6b30bf3/static/Makefile

Try to build on a ARM64 VM like ec2.
