Updating a Heroku deployment

[douglasac10]

Hi,

We have an instance of Password Pusher that we have running on a Heroku deployment. We absolutely love it!

What is the best way of updating this one?

Thanks!

Hi @douglasac10 - thanks for the nice words!

It depends on how you have it setup but most common way to update your Heroku deployment from the CLI (using the heroku command) is:

git checkout master
git pull origin --rebase
git push heroku master

# Then run the database migration to update the database tables (no data is lost)
heroku run rails db:migrate

Before you do that, it's always good to know/have some safeties:

1. Backup and export the database first: heroku pg:backups:capture --app application-name
2. Know about releases and how to rollback in case of error: heroku releases && heroku rollback

Also check the latest version of the configuration document. There are some new options that you may want to set. You can add these environment variables with heroku config:set PWP__DEFAULT_LOCALE =es. See also the heroku docs.

I hope this helps!

Thanks for that - worked a treat!

I did have to add the variable BUNDLE_WITH=postgres to the Config Vars (as mentioned here), but once that was done all good :)

Doh good point - that step is new in the last few months. Glad to hear everything is updated!
