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:
