Docker doesn't seem to be mapping ports - docker

Question

I'm working with Hugo
Trying to run inside a Docker container to allow people to easily manage content.
My first task is to get Hugo running and people able to view the site locally.
Here's my Dockerfile:
FROM alpine:3.3
RUN apk update && apk upgrade && \
apk add --no-cache go bash git openssh && \
mkdir -p /aws && \
apk -Uuv add groff less python py-pip && \
pip install awscli && \
apk --purge -v del py-pip && \
rm /var/cache/apk/* && \
mkdir -p /go/src /go/bin && chmod -R 777 /go
ENV GOPATH /go
ENV PATH /go/bin:$PATH
RUN go get -v github.com/spf13/hugo
RUN git clone http://mygitrepo.com /app
WORKDIR /app
EXPOSE 1313
ENTRYPOINT ["hugo","server"]
I'm checking out the site repo then running Hugo - hugo server
I'm then running this container via:
docker run -d -p 1313:1313 --name app app
Which reports everything is starting OK however when I try to browse locally on localhost:1313 I see nothing.
Any ideas where I'm going wrong?
UPDATE
docker ps gives me:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
9e1f12849044 app "hugo server" 16 minutes ago Up 16 minutes 0.0.0.0:1313->1313/tcp app
And docker logs 9e1 gives me:

Answer 1

I had the same problem, but following this tutorial http://ahmedalani.com/post/so-recursive-it-hurts/, says about to use the param --bind from hugo server command.
Adding that param mentioned, and the ip 0.0.0.0 we have --bind=0.0.0.0
It works to me, I think this is a natural behavior from every container taking a localhost for self scope, but if you bind with 0.0.0.0 takes a visible scope to the main host.

Answer 2

This is because Docker is actually running in a VM. You need to navigate to the docker-machine ip instead of localhost.
curl $(docker-machine ip):1313

Answer 3

Delete EXPOSE 1313 in your Dockerfile. Dockerfile reference.
