“exec：”go “：$ PATH中找不到可执行文件”

Posted 2021-03-26

我已经创建了dockerfile，成功构建了它，但是当我运行它时

sudo docker run -d -it -p 15555：9888 --name = docker-golang-test goTestDocker go run 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：”go “：$ 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

答案

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

这是一个多级dockerfile，你复制项目，获取依赖项并构建它，然后在第二个，你只需运行它（由CMD ["./app"]）

如果你想以你的方式做到这一点：

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

是你想要的dockerfile（我的建议是第一个因为它只是通过docker run命令运行）

PS：multistage dockerfile
