Dockerfile addition

[naxels]

Hi,

Love the simplicity of the app and the simple REST API exposure
was able to get it working and getting feeds in no-time using Postman :)

A suggestion I would like to make is to add a Dockerfile, so people can run the app without needing Go/install etc
to get it working and trying it out.

Here is a sample script that works, however doesn't have Node, doesn't persist the SQLite DB, and doesn't automatically start the app when the container runs:

FROM golang

WORKDIR /go/src/app
COPY . .

RUN go get -d -v ./...
RUN go install -v ./...

EXPOSE 8080/tcp

# CMD ["go run arss --client client/public --headless"]

Thank you and keep up the good work!

Thank you for filing an issue!

I'm down to add a Dockerfile. I'll test the base script you've provided, and will make any modifications if needed
