Update Dockerfile to Best Practices: - Version pinning on Base Image - COPY is preferred over ADD - apk -U will leave index in image, use `--no-cache` to avoid storing repo index - curl kubectl directly to final destination - Change entrypoint instead of running `sh -c bash -c /bin/update.sh` 2017-02-20 09:53:03 +00:00			`FROM alpine:3.4`
