Docker中的Golang Build找不到本地导入

Question

I am pretty new to GoLang. I have a pretty simple dockerFile that is trying to build a goLang webservice.

FROM golang:alpine

WORKDIR /app/webservice_refArch
ADD . /app/webservice_refArch

RUN apk add git
RUN apk upgrade

RUN cd /app/webservice_refArch/ && go get webservice_refArch/restapi
RUN cd /app/webservice_refArch/cmd/reference-w-s-server && go build -o ../../server
ENTRYPOINT ./goapp

When the build runs it cannot find a local import.

go get webservice_refArch/restapi

The error that I get is:

package webservice_refArch/restapi: unrecognized import path "webservice_refArch/restapi" (import path does not begin with hostname)

When I run that same command on my local (in the same folder) it runs just fine. I am sure that I am missing something stupid but any thoughts on why it fails when running from docker would be appreciated.

Answer 1

It was because I wasn't copying over to my GOROOT location. As a result, when it was trying to find the local resource it wasn't in the GOROOT spot.

Changing the dockerFile to look like this worked...

FROM golang:alpine

WORKDIR /go
ADD . /go/src/webservice_refArch

RUN apk add git
RUN apk upgrade

RUN cd /go/src/webservice_refArch/ && go get ./...
RUN cd /go/src/webservice_refArch/cmd/reference-w-s-server && go build -o ../../server
ENTRYPOINT ./goapp
