Build Docker with Go app: cannot find package

Question

I have my Dockerfile in the root of directory with src/myapp folder, myapp contains myapp.go with main package.

Dockerfi

Answer 1

If the objective is to create a container that simply runs your binary, I would take different approach.

First build the binary for linux:

GOOS=linux CGO_ENABLED=0 go build -a -installsuffix cgo

Then build a lightweight docker image from scratch:

FROM scratch
COPY myApp 
CMD ["/myApp"]
