if i want to apply a patch and create new docker image, which of the Dockerfiles in github repo should i use? They all seem to be out-dated and do not work

Why do you think they are outdated/do not work? What docker repo are you using?

i am using repo v0.38.15-beta.1 If i run "docker build" specifying "Dockerfile" or "Dockerfile-dc", the image is not created, there are errors

Run "make docker"

cat: .bin/.lock: No such file or directory

go build -o .bin/go-acc <http://github.com/ory/go-acc|github.com/ory/go-acc>

/bin/bash: go: command not found

make: *** [Makefile:9: deps] Error 127

You need to install golang
