Deployment

What I Did

1. Met with Ben to go over FED and Dev work-flow to keep things same going forth with the intern group project.
2. I spent most of the day debugging errors while attempting to deploy “These Numbers Matter” from my functioning local environment to Heroku. Foolishly, I had not been deploying along the way, so I ended up spending a ton of time researching things that, though important to know, were completely unrelated to the problem at hand.

   What I Learned

3. Continuous integration is a development practice that allows for developers to integrate code frequently throughout a given day. Each code check-in is verified by an automated build, decreasing the amount of time spent later on tracking down bugs. CircleCI provides this service.
4. Ben mentioned that it may be possible to pull in new production changes directly into our our local master and staging environments using a rake task. I’ve yet to look into this further.
5. Dragonfly is a ruby gem for on-the-fly image processing suitable for Rails, Sinatra, etc.
6. Heroku buildpacks transform deployed code into a slug, which can then be conveniently executed on a dyno.
7. Slugs are compressed and pre-packaged copies of you application optimized for distribution to the dyno manager.
8. A dyno is a lightweight Linux container that runs a single user-specified command. A dyno can run any command available in its default environment.
9. A LXC (Linux Container) is an operating-system-level virtualization method for running multiple isolated Linux systems (containers) on a control host using a single Linux kernel.
10. A daemon is a long-running background process that answers requests for services.
11. The following situations entail running multiple buildpacks for your Heroku app -
    • a buildpack for each language you utilize in your app (e.g. JavaScript buildpack for node modules)
    • run a daemon process such as pgbouncer within you application
    • pull in system dependencies with apt

      What I Still Don’t Understand

      I’m still not entirely sure how to go about seeding images for ease of setting up a functioning environment for “These Numbers Matter” replete with the appropriate content and images.
