Extend and override nginx config for Elastic Beanstalk Amazon Linux 2

Documentation on how to override or extend the default nginx config on Elastic Beanstalk running om Amazon Linux 2. Correct as of 2021-08-01. Also see the general documentation on how to extend linux servers.

All references to placing files refer to putting a file at this location in your application bundle. You should never modify a file directly at your Elastic Beanstalk server by ssh:ing to the server, since such a change will be wiped whenever your servers autoscale or if you rebuild your application completely.

Adding a new location block

The easiest extension is to add a new location block to the main server block. This can be done by placing a .conf file with a server block in the folder .platform/nginx/conf.d/elasticbeanstalk. Any such file is automatically included in the main server block.

Overriding the default location

# Runs rake assets:clean
# Defaults to nil (no asset cleanup is performed)
# If you use Rails 4+ and you'd like to clean up old assets after each deploy,
# set this to the number of versions to keep
set :keep_assets, 2

# Clear existing task so we can replace it rather than "add" to it.
Rake::Task["deploy:compile_assets"].clear

Because I couldn't find these with a quick Google search on 28 April 2015:

Usage:
  rails new APP_PATH [options]

Options:
  -r, [--ruby=PATH]                                      # Path to the Ruby binary of your choice
                                                         # Default: /home/brian/.rvm/rubies/ruby-2.2.0/bin/ruby
  -m, [--template=TEMPLATE]                              # Path to some application template (can be a filesystem path or URL)
      [--skip-gemfile], [--no-skip-gemfile]              # Don't create a Gemfile

jquery.scrollLock.js

Useful for when a blocking user experience is needed (in my case, didn't want people unwittingly loosing their place by scrolling while a modal required their attention): $.scrollLock() locks the body in place, preventing scroll until it is unlocked.

// Locks the page if it's currently unlocked
$.scrollLock();

// ...or vice versa
