无法使用Docker为Golang应用创建映像

I try to create an image for my Golang application, but Docker just writes:

Step 7/9 : RUN go install ./accounting/server
 ---> Running in f998ba6a5efb
can't load package: package grpcProjects/multiService/accounting/server: cannot find package "grpcProjects/multiService/accounting/server" in any of:
        /usr/local/go/src/grpcProjects/multiService/accounting/server (from $GOROOT)
        /go/src/grpcProjects/multiService/accounting/server (from $GOPATH)

My Dockerfile:

FROM golang:1.10.4

ADD . /go/src/grpcProjects/multiService

WORKDIR /go/src/grpcProjects/multiService

RUN go get github.com/golang/protobuf/proto
RUN go get golang.org/x/net/context
RUN go get google.golang.org/grpc
RUN go install ./accounting/server

ENTRYPOINT [ "/go/bin/server" ]

EXPOSE 8080

How to solve this problem?

I've found a solution. Everything went wrong because I used this command from the root directory of the project:

$ docker build -t accounting_server ./accounting

And multiService/accounting was my building directory, so file hierarchy in the image looked like that:

/go/src/grpcProjects/multiService
/go/src/grpcProjects/multiService/server
/go/src/grpcProjects/multiService/server/service
/go/src/grpcProjects/multiService/server/service/accounting.go
/go/src/grpcProjects/multiService/server/main.go
/go/src/grpcProjects/multiService/proto
/go/src/grpcProjects/multiService/proto/accounting.proto
/go/src/grpcProjects/multiService/proto/accounting.pb.go
/go/src/grpcProjects/multiService/Dockerfile

Docker just copied the contents of local /multiService/accounting to /multiService directory of the image. So I had to change Dockerfile a bit:

FROM golang:1.10.4

ADD . /go/src/grpcProjects/multiService

RUN go get github.com/golang/protobuf/proto
RUN go get golang.org/x/net/context
RUN go get google.golang.org/grpc
RUN go install grpcProjects/multiService/accounting/server

ENTRYPOINT [ "/go/bin/server" ]

EXPOSE 8080

And I built my container with the next command:

$ docker build -t accounting_server -f ./accounting/Dockerfile .

Still from the root directory so everything was copied to the image properly.

Thanks to everyone who replied!
