The built in go http.Fileserver handles If-Modified-Since in the header by comparing it with the last modified date on the file/directory. Since the file is unaltered when we switch to a new container, that results in 304s when trying to fetch data.json, so the browser doesn't fetch the new picture after doing a rolling update. Separate issue, the Dockerfile ADD command was being interpreted as `copy html/data.json into a directory called 'html/kitten.jpg '`, instead of the `copy these 2 files into root`. Changed to separate commands using COPY, per recommended dockerfile practices.
