https://github.com/apache/incubator-metron/pull/472
While reviewing this I had an idea for another PR that would make this
easier to use. The slowest part of spinning this up is downloading the kafka
and hbase distributions. What would you think of splitting these Dockerfiles
into 2 separate images: one with just the service installed (kafka or hbase)
and another that extends the service and installs the Metron bits on top? This
would allow us to quickly deploy Metron changes and rebuild. To get that to
work we would need to a way to get the base image installed locally. Initially
this could just be a build script that needs to be run once before spinning the
application up and long term it could live in Docker Hub.
What do you think of this idea? Would it be helpful? I'm a little
hesitant to add a manual step that needs to be done before the application will
work but I don't want to add that hook into the build process, even if we do
add a check for a running Docker machine. Maybe publishing to Docker Hub now
is the answer. Any feedback or ideas?
