如果代码不在Internet上托管，如何导入软件包

Question

I have a package structure

$GOPATH/src/io.sure/api/proto/vi/party.pb.go
        .../io.sure/party/party.go
        ../io.sure/Dockerfile

import of party.go are

import (  
    "context"
    "google.golang.org/grpc"
    "io.sure/api/proto/v1"
    "log"
    "net"
)

FROM golang:1.12.1-alpine AS builder   
RUN apk update && apk add --no-cache git   
WORKDIR /go/src/app  
COPY ./party/ .  
COPY ./api/ .  
RUN go get -d -v  
RUN CGO_ENABLED=0 go install

FROM scratch  
WORKDIR /opt  
COPY --from=builder /go/bin/app .  
ENTRYPOINT ["/opt/app"] 

The code compiles and runs from a command line. But when I build a docker image, go get tries to download io.sure/api/proto/v1 even when i have a copied the api folder in the docker image. How can i stop/skip downloading the package, as I do not have the code on github or any other public repo.

Is vendoring a right thing to do, since its my own package which may not be exported or exported to outside world.

I tried go modules but i am facing issues and still want to work with GOPATH.

ried both the combinations but still the same error. code does get copied in image gopath.

FROM golang:1.12.1-alpine AS builder RUN apk update && apk add --no-cache git WORKDIR $GOPATH/src/io.sure COPY ./party/ . COPY ./api/ . RUN go get -d -v RUN CGO_ENABLED=0 go install

FROM scratch WORKDIR /opt COPY --from=builder /go/bin/app . ENTRYPOINT ["/opt/app"]

FROM golang:1.12.1-alpine AS builder RUN apk update && apk add --no-cache git WORKDIR $GOPATH/src RUN mkdir -p $GOPATH/src/io.sure COPY ./party/ . COPY ./api/ . RUN go get -d -v RUN CGO_ENABLED=0 go install

Answer 1

The content of your $GOPATH differs between cli and Dockerimage in that your packages are not in the right place.

You need to RUN mkdir -p $GOPATH/src/io.sure and COPY ./party $GOPATH/src/io.sure/ to achieve the same layout in the Dockerimage like on the cli.

You probably need to adapt the Paths but I hope you get the idea
