We don't want our CMS images served from our disk in production, so we need to set up a CDN. I'll use S3 as that's what I know.
Setting up S3 is a matter of uncommenting some settings in your config/storage.yml file:
amazon:
service: S3
access_key_id: <%=ENV.fetch("AWS_ACCESS_KEY_ID")%>
secret_access_key: <%= ENV.fetch("AWS_SECRET_ACCESS_KEY") %>
region: us-west-1
bucket: bigrails
public: true
You then need to set config/environments/production.rb to use the amazon provider:
config.active_storage.service = :amazon
