Heroku has a LOT of docs, usually well-written. It is pretty well googled. Some heroku overview and getting started docs:

• https://devcenter.heroku.com/articles/getting-started-with-rails6

• https://devcenter.heroku.com/articles/how-heroku-works

• https://devcenter.heroku.com/articles/git#creating-a-heroku-remote

Intersting heroku add-on I noticed, rails-autoscale – instead of needing to build out as many dynos as we might need to handle maximum traffic or ingest, we can have the add-on scale up automatically with use. Works for both web dynos (with traffic), and background job dynos (when we do a big ingest, it can scale up more workers!). Does cost money, price based on how high you want it to be able to scale I think.

I think I will try to get our app on heroku piece by piece…

1. Get app deployed to heroku with postgres small web dyno only – no bg jobs yet, no solr yet. (Solr functions won’t work!)

2. Add in bg jobs – including heroku buildpacks with all the software they need (vips, imagemagick, ffmpeg, egc).

3. Add in solr – not sure whether to start by trying to have it connect to existing staging solr (which would require a heroku add-on for a static outgoing IP via SOCKS, so we could let it through our solr firewall, and/or other solr changed config), OR move right away to a SaaS solr – which would cost money, have to identify which one we need.

4. App substantially working at this point, but still lots of little pieces to get in place, such as nightly jobs.
