“ exec：\” go \”：在$ PATH中找不到可执行文件”

Question

I have created dockerfile, successfully built it, but when I run it

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

it returns an error

docker: Error response from daemon: OCI runtime create failed: container_linux.go:348: starting container process caused "exec: \"go\": executable file not found in $PATH": unknown.

This is my Docker file

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

this is a multistage dockerfile which you copy the project, fetch dependencies and build it, and then in second one, you just run it (by CMD ["./app"])

if you want to do it in your way:

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

is the dockerfile you want (my suggestion is ofc first one cause it runs just by docker run command)

PS: multistage dockerfile
