Go executable not found when using golang container

[codeblooded]

First things first, the version numbers:

$ docker version
Client:
 Version:      17.03.1-ce
 API version:  1.27
 Go version:   go1.7.5
 Git commit:   c6d412e
 Built:        Tue Mar 28 00:40:02 2017
 OS/Arch:      darwin/amd64

Server:
 Version:      17.03.1-ce
 API version:  1.27 (minimum version 1.12)
 Go version:   go1.7.5
 Git commit:   c6d412e
 Built:        Fri Mar 24 00:00:50 2017
 OS/Arch:      linux/amd64
 Experimental: true

$ docker-compose version
docker-compose version 1.11.2, build dfed245
docker-py version: 2.1.0
CPython version: 2.7.12
OpenSSL version: OpenSSL 1.0.2j  26 Sep 2016

I'm getting the following error:

Cannot start service web: oci runtime error: container_linux.go:247: starting container process caused "exec: \"go\": executable file not found in $PATH"

And this is my Dockerfile:

FROM golang:1.8

WORKDIR /go/src/gigem
COPY . /go/src/gigem

RUN go build
RUN go install

CMD ["gigem"]

I'm also using Compose (and I'll include the yml, but the error occurs with/without compose):

version: '3'
services:
  db:
    image: postgres
    volumes:
      - ./data:/var/lib/postgresql/data
  web:
    build: .
    volumes:
      - .:/go/src/gigem
    ports:
      - "3000:3000"
    depends_on:
      - db

And all that's in my Go program is:

package main

import (
	"fmt"
	"net/http"
)

func main() {
	http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
		fmt.Fprintf(w, "Hello Docker!")
	})

	fmt.Println("Running!")
	fmt.Println(http.ListenAndServe("0.0.0.0:3000", nil))
}

I'm not quite sure why go is not being found in the $PATH.

Strangely enough... I think this may be a bug with Docker and not this specific container. When launching a bash session in the container interactively, I see that go is part of the $PATH. So, I then attempted to run the executable manually. It returned:

standard_init_linux.go:178: exec user process caused "exec format error"

So it appears the executable that the container built is malformed. I manually rebuilt the executable in the bash session, and it worked as expected. I'm thinking this may be an issue with volumes and Docker for Mac. Perhaps, the build tool is somehow compiling for the mac architecture instead of the linux. I'm not entirely sure. It's really weird.

I asked on StackOverflow here and got some helpful advice. It seems to be a rare behavior though!

Literally restarted my machine and it worked. I think docker just needed to be completely killed off and restarted. I'm closing this b/c this seems to be more of an issue with docker.
