Question

我的Dockerfile

FROM golang:1.10.2-alpine3.7 AS build
RUN apk --no-cache add gcc g++ make ca-certificates
RUN apk add git
WORKDIR /go/src/github.com/meower

COPY Gopkg.lock Gopkg.toml ./
COPY util util
COPY event event
COPY db db
COPY search search
COPY schema schema
COPY meow-service meow-service
COPY query-service query-service
COPY pusher-service pusher-service

RUN go get -d -v ./...
RUN go install ./...

FROM alpine:3.7
WORKDIR /usr/bin
COPY --from=build /go/bin .

我添加了apk添加git行。没有这一行，我的docker-compose up产生了

Step 13/17 : RUN go get -d -v ./...

使用git行，其他问题仍然存在

docker-compose up

这是什么意思？

Answer 1

go get在内部调用特定VCS的“参考”客户端工具，该工具用于托管要获取的程序包。换句话说，go get本身不知道如何与VCS服务器进行交互。

是的，为了go get由Git托管的软件包，您需要工作的Git安装程序提供可调用的git二进制文件。

关于第二个问题，does not appear to have anything related to Go，所以我建议您做一点研究，然后再问一个标记为alpine的单独问题，如果失败了。

调用`go get`时缺少Git命令
