Not possible to build docker from scratch ?

[buczek]

It looks to me like this tool requires docker already being available on the build system.

If so, the README should mention that. And if there is a way at all to build docker-ce from source only without using precompiled static binaries, a hint would be nice, too.

buczek@theinternet:~/git/docker-ce-packaging (master)$ make static
./scripts/checkout.sh src/github.com/docker/cli "HEAD"
+ SRC=src/github.com/docker/cli
+ REF=HEAD
[...]
+ git -C src/github.com/docker/scan-cli-plugin checkout -q refs/tags/v0.17.0
for p in static-linux cross-mac cross-win cross-arm; do \
	make -C static VERSION=0.0.1-dev GO_VERSION=1.18.5 TARGETPLATFORM= CONTAINERD_VERSION= RUNC_VERSION= ${p}; \
done
