用于 golang 应用程序的 Docker

Question

我有一个 golang 应用程序，我想为它构建 docker 镜像名为 cloud-native-go 的应用程序文件夹和 dockerfile 在根项目下知道这里出了什么问题吗？

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

我用

构建它

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

Answer 1

go-wrapper 已弃用并从使用 go 版本 10 及更高版本的图像中删除。参见 here .

如果您可以使用 go v1.9，您可以使用以下图像: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
