Memcached – Go applications fails and exits when running using docker-compose, but works fine with docker run command

I am running all of these operations on a remove server that is a
VM running Ubuntu 16.04.5 x64.

My Go project’s Dockerfile looks like:

FROM golang:latest

ADD . $GOPATH/src/example.com/myapp
WORKDIR $GOPATH/src/example.com/myapp
RUN go build

#EXPOSE 80

#ENTRYPOINT $GOPATH/src/example.com/myapp/myapp
ENTRYPOINT ./myapp
#CMD ["./myapp"]

When I run the docker container using docker-compose up -d, the Go application exits and I see this in the docker logs:

myapp_1 | /bin/sh: 1: ./myapp: Exec format error docker_myapp_1
exited with code 2

If I locate the image using docker images and run the image like:

 docker run -it 75d4a95ef5ec 

I can see that my golang applications runs just fine:

viper environment is: development HTTP server listening on address:
“:3005”

When I googled for this error some people suggested compiling with some special flags but I am running this container on the same Ubuntu host so I am really confused why this isn’t working using docker.

My docker-compose.yml looks like:
