Update Dockerfile

[nporteschaikin]

• Use standard node image (includes git)

Tested this - it builds and runs.

What was the node version on the old image? What does this do to the size of the image?

[gdiggs]

You can get a nice size bump if you add this into the next line:

RUN apk --update add git && \
      git clone https://github.com/etsy/statsd.git && \
      cd statsd && git reset --hard v0.7.2 && \
      apk del git && \
     npm install statsd-librato-backend statsd-datadog-backend

Glad you asked. Using node was a mistake; it's massive (>700 MB). Moved to a tagged version of alpine. 20 MB on master, 77.5 MB here.

Nice

60 MB now.
