"exec：\"go\"：在$PATH中找不到可执行文件“

Question

我已经创建了dockerfile，成功地构建了它，但是当我运行它时

数独码头运行-d -it -p 15555:9888 --名称= docker -golang-test goTestDocker go main.go host=0.0.0.0

它返回一个错误。

docker:来自守护进程的错误响应: OCI运行时创建失败: container_linux.go:348:启动容器进程导致"exec：\“：可执行文件在$PATH中找不到”未知“。

这是我的码头文件

FROM golang:1.10.2-alpine3.7 AS build 
RUN apk --no-cache add gcc g++ make ca-certificates
WORKDIR /home/user/Desktop/work/go-work/GoProject/project

RUN go get github.com/golang/protobuf/proto

Answer 1

FROM golang:1.10.2-alpine3.7 AS build 
RUN apk --no-cache add gcc g++ make ca-certificates
WORKDIR /go/src/github.com/{$whoami}/testProject
RUN ls
RUN pwd
COPY . .
RUN pwd
RUN apk update -qq && apk add git
RUN go get github.com/golang/protobuf/jsonpb
RUN go get github.com/golang/protobuf/proto
RUN go build .

FROM alpine:3.7
WORKDIR /usr/bin
COPY --from=build /go/src/github.com/{$whoami}/testProject/testProject .
EXPOSE 9888
CMD ["./app"] --v

这是一个多阶段的dockerfile，您可以复制项目、获取依赖项并构建它，然后在第二个阶段只运行它(通过CMD ["./app"])。

如果你想用你的方式去做：

FROM golang:1.10.2-alpine3.7
RUN apk --no-cache add gcc g++ make ca-certificates
WORKDIR /go/src/github.com/{$whoami}/testProject
COPY . .
RUN apk update -qq && apk add git
RUN go get github.com/golang/protobuf/jsonpb
RUN go get github.com/golang/protobuf/proto

是您想要的dockerfile (我的建议是ofc，因为它只是通过docker run命令运行)
