Code in docker shutdown post seems imcomplete

[kongakong]

First of all, thanks for a great article about docker shutdown: https://husobee.github.io/golang/ecs/2016/05/19/ecs-graceful-go-shutdown.html

I am trying to run your code to better understand the concept.

I put the main piece of go code from your blog post into a file main.go and put in a subdirectory './app' directory. I totally just make this up because it is not clear how to name the go file. Then I created the Dockerfile and run the docker build.

No problem at this stage.

Here is directory structure:

> tree                                                                                                                                  
.
├── Dockerfile
└── app
    └── main.go

When I bring up the docker process, I go this error:

> docker run e74e925e6789                                                                                                                
container_linux.go:262: starting container process caused "exec: \"/app\": permission denied"
docker: Error response from daemon: oci runtime error: container_linux.go:262: starting container process caused "exec: \"/app\": permission denied".

I think there is something missing with the Dockerfile?

Thank you so much for letting me know. I will try to get that corrected as soon as possible.
