How to grant permissions to AWS user for Hartl’s rails tutorial

Question 1

I don’t know how (or where also) to grant read and write permission to the user from AWS so users can post pictures on sample_app in production enviroment. This is final task in 11th chapter, it isn’t covered by tutorial and I can’t find solution anywhere.

This is carrier_wave.rb file:

if Rails.env.production?
  CarrierWave.configure do |config|
    config.fog_credentials = {
      # Configuration for Amazon S3
      :provider              => 'AWS',
      :aws_access_key_id     => ENV['lalala'],
      :aws_secret_access_key => ENV['oloalle']
    }
    config.fog_directory     =  ENV['name of bucket']
  end
end

if Rails.env.production?

CarrierWave.configure do |config|

config.fog_credentials = {

# Configuration for Amazon S3

:provider => 'AWS',

:aws_access_key_id => ENV['lalala'],

:aws_secret_access_key => ENV['oloalle']

}

config.fog_directory = ENV['name of bucket']

end

This is procedure from tutorial:
1) create AWS IAM User and record access and secret key – done

2) create S3 bucket – done

3) grant read and write permission to the user created in the previous step – how???

4) I then run this three commands:

$ heroku config:set S3_ACCESS_KEY=lalala
$ heroku config:set S3_SECRET_KEY=oloalle
$ heroku config:set S3_BUCKET=name of bucket

$ heroku config:set S3_ACCESS_KEY=lalala

$ heroku config:set S3_SECRET_KEY=oloalle

$ heroku config:set S3_BUCKET=name of bucket

5) push to git and heroku – done

6) heroku pg:reset DATABASE – done

7)heroku run rake db:migrate and here I get this message:

Question 2

For others in future, this answer helped me a lot.

Go on Heroku, on your application, go to settings, hit Reveal Config Vars.

Click on on Edit on the right side and enter your secrets there:

S3_BUCKET: name of your bucket goes here
S3_ACCESS_KEY: xxxxx
S3_SECRET_KEY: xxxx

S3_BUCKET: name of your bucket goes here

S3_ACCESS_KEY: xxxxx

S3_SECRET_KEY: xxxx

On config/initializers/carrierwave.rb or wherever you’re entering your secrets should have:

CarrierWave.configure do |config|
  config.root = Rails.root.join('tmp') # adding these...
  config.cache_dir = 'carrierwave' # ...two lines

  config.fog_credentials = {
    :provider               => 'AWS',                        # required
    :s3_access_key_id      => ENV['S3_ACCESS_KEY'],                        # required
    :s3_secret_access_key  => ENV['S3_SECRET_KEY'],                     # required
    :region                 => 'eu-west-1',                  # optional, defaults to 'us-east-1'
    :host                   => 's3.example.com',             # optional, defaults to nil
    :endpoint               => 'https://s3.example.com:8080' # optional, defaults to nil
  }
  config.fog_directory  = ENV['S3_Bucket']                             # required
  config.fog_public     = false                                   # optional, defaults to true
  config.fog_attributes = {'Cache-Control'=>'max-age=315576000'}  # optional, defaults to {}
