Docker for Golang应用程序 [英] Docker for golang application

问题描述

我有golang应用程序，我想为其构建docker映像名为 cloud-native-go 的应用程序文件夹，而dockerfile在根项目下知道这里有什么问题吗?

i've golang application which I want to build docker image for it the application folder called cloud-native-go and the dockerfile is under the root project Any idea what is wrong here ?

FROM golang:alpine3.7
WORKDIR /go/src/app
COPY . .
RUN apk add --no-cache git
RUN go-wrapper download   # "go get -d -v ./..."
RUN go-wrapper install    # "go install -v ./..."

#final stage
FROM alpine:latest
RUN apk --no-cache add ca-certificates
COPY --from=builder /go/bin/app /app
ENTRYPOINT ./app
LABEL Name=cloud-native-go Version=0.0.1
EXPOSE 3000

错误是:

Step 5/12 : RUN go-wrapper download   # "go get -d -v ./..."
 ---> Running in 70c2e00f332d
/bin/sh: go-wrapper: not found

i用

docker build -t cloud-native-go:1.0.0.

推荐答案

go-wrapper 已被弃用，并已使用 go 10及更高版本从图像中删除.请参见此处.

go-wrapper has been deprecated and removed from the images using go version 10 and above. See here.

如果您很好地使用 go v1.9 ，则可以使用以下图像: golang:1.9.6-alpine3.7 .

If you are fine using go v1.9 you can use the following image: golang:1.9.6-alpine3.7.

因此，您的 Dockerfile 将是:

FROM golang:1.9.6-alpine3.7
WORKDIR /go/src/app
COPY . .
RUN apk add --no-cache git
RUN go-wrapper download   # "go get -d -v ./..."
RUN go-wrapper install    # "go install -v ./..."

#final stage
FROM alpine:latest
RUN apk --no-cache add ca-certificates
COPY --from=builder /go/bin/app /app
ENTRYPOINT ./app
LABEL Name=cloud-native-go Version=0.0.1
EXPOSE 3000
