Juju Actions - Use Cases

[Charles Butler]

There are a slew of opportunities for Actions to step in here, and I've got
a few use cases listed below:


   - HDFS file system operations in Big-Data scenarios
   - dump/warm cache on proxy services like Varnish
   - Ingest data-sources with any database (ex: load twitter hash-tag data
   into ElasticSearch)
   - Rebuild indexes in MongoDB
   - Trigger deployment from source-control on framework based charms
   (Rails, NodeJS, CakePHP)
      - as an interesting aside, we are kind of brute forcing this with
      config... which it really appears that an action would be better
suited to
      this task for things like, say, CI
   - Generating passwords post deployment for admin accounts instead of
   dumping a random pass in the logs or to /var/myservice/itsasecret.pwd
   - executing framework actions (eg: rake db:seed on rails)
   - Deploying additional demo assets in existing charms (see the demo.sh
   in the elasticsearch bundle)



These are just a few to kick this conversation into gear as other's come
into it and start brain bending around where their charm could benefit from
an action.

all the best,

Charles
