How to build docker-ce from source on macOS - docker

Question

Anyone knows if there's a guide to build from source and replace docker binary on Mac with it?
The readme doesn't say so I try some make target but got https://github.com/docker/for-mac/issues/3353
Edited
What I was trying to do, to be exact, is to debug docker cli to see why the Auth doesn't work for a single developer in my former company, regardless all factor checked and verified to be correct.

Answer 1

To do this, checkout the repo of docker cli (it was confusing at first which part of docker live where). But the cli is at:
git#github.com:docker/cli.git
Build it( this build dist for all platform), assuming you have make already:
make -f docker.Makefile binary cross
Then either use this binary(this is for Mac), for example:
build/docker-darwin-amd64 pull mysql
Or backup and replace your original /usr/local/bin/docker with the binary above.

Since on macOS you're not going to run the engine, you may try a different approach. Building the docker client using the Makefile requires docker engine, and a docker client, which you may not have.
I'm building docker (the client) from the docker/cli repository as a plain Go project:
Clone the repo:
$ git clone https://github.com/docker/cli.git
Build master, or checkout a specific tag:
$ git checkout v19.03.6
cd into the repo, create a build directory, and create the require Go project structure:
$ cd cli
$ mkdir -p build/src/github.com/
$ cd build/src/github.com/
$ ln -s ../../.. cli
cd into the build directory and set the GOPATH:
$ cd ../..
$ export GOPATH=$(pwd)
Build the docker client:
$ go build github.com/docker/cli/cmd/docker
Copy the binary from the build directory, e.g.:
$ cp docker /usr/local/bin
You'll notice that some build-related information is not set:
./docker version
Client:
Version: unknown-version
API version: 1.40
Go version: go1.13.8
Git commit: unknown-commit
Built: unknown-buildtime
OS/Arch: darwin/amd64
Experimental: false
You can pass a suitable -ldflags argument to set those variables as in:
$ go build \
-ldflags \
"-X github.com/docker/cli/cli/version.GitCommit=${docker_gitcommit} \
-X github.com/docker/cli/cli/version.Version=${version} \
-X \"github.com/docker/cli/cli/version.BuildTime=${build_time}\""
provided you have set the docker_gitcommit, version and build_time variables. The escaped quotes in the third flag are required if build_time contain spaces (as the upstream docker binaries do).
Hope this helps.
