无法使用Docker为Golang应用创建映像

Question

我尝试为我的Golang应用程序创建映像，但是Docker只写：

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)

我的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

如何解决这个问题？

Answer 1

我找到了解决方案。一切都出错了，因为我在项目的根目录中使用了以下命令：

$ docker build -t accounting_server ./accounting

multiService/accounting是我的建筑目录，因此图像中的文件层次结构如下所示：

/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 刚刚将本地/multiService/accounting的内容复制到了映像的/multiService目录中。所以我不得不稍微更改 Dockerfile ：

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

然后用下一条命令构建容器：

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

仍然位于根目录中，因此所有内容均已正确复制到映像。

感谢所有回答！
