Question

我已经创建了dockerfile，成功构建了它，但是当我运行它

sudo docker run -d -it -p 15555：9888 --name = docker-golang-test goTestDocker go run main.go host = 0.0.0.0

返回错误

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

这是我的Docker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 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
FROM alpine:3.7
WORKDIR /usr/bin
COPY --from=build /go/bin .
EXPOSE 9888
CMD ["./app"] --v

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，获取依赖项并进行构建，然后在第二个文件中，只需运行它（通过CMD ["./app"]）

如果您想以自己的方式这样做：

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（我的建议是第一个，因为它仅通过docker run命令运行）

PS：multistage dockerfile

“ exec：\” go \“：在$ PATH中找不到可执行文件”
