Getting executable file not found in $PATH: un known error message

I'm getting executable file not found in $PATH: unknown error while trying to run docker image of golang project. Following is my docker file.

FROM golang:latest
LABEL maintainer = "Nisal Perera <[email protected]>"
RUN mkdir -p /go/src/github.com/user/app/
COPY . /go/src/github.com/user/app/
WORKDIR /go/src/github.com/user/app/
RUN go get -u github.com/golang/dep/cmd/dep
#RUN dep init
RUN dep ensure
RUN go build
CMD ["go run main.go"]

The error I'm getting is the following

docker: Error response from daemon: OCI runtime create failed: container_linux.go:370: starting container process caused: exec: "go run main.go": executable file not found in $PATH: un
known.

Please help me with this. thanks

You dont need to use go run ... since you previously run go build, built file will be named after directory and looks like its app, try CMD ["./app"]

BTW the right usage of CMD in your case would be CMD ["go", "run", "main.go"], the error you have is related to CMD command its assume go run main.go is one file but it's not.

You're trying to use the CMD clause in its exec form so you have to split the command and its arguments. The accepted format is

CMD ["executable","param1","param2"]

So yours would be

CMD ["go", "run", "main.go"]

You are getting this error as the file "main.go" is not available at the working directory where it is executing the "go run main.go" command.

Please check the main.go file is available or not if yes then please define the complete path for the main.go file and try.
