Be sure to use your domain when going public. 77 | 78 | ## DreamObjects S3 79 | See: https://help.dreamhost.com/hc/en-us/articles/216201557-How-to-setup-Cross-Origin-Resource-Sharing-CORS-on-DreamObjects 80 | 81 | 82 | ## CNAME your S3 bucket (optional) 83 | 84 | Objects will be available by accessing the public URL directly. Example: 85 | `http://bucket-name.s3.amazonaws.com/uploads/439fbca8-b79b-40e9-8172-4d318737ee14_file.jpg` 86 | 87 | However, if you wish to customize the URL, you can use a CNAME. First, create/rename your bucket to match the 88 | subdomain (`uploads.domain.com`). Then create the CNAME (via your DNS settings) using the exact name of the 89 | bucket/subdomain. 90 | 91 | To be clear, the bucket's name and CNAME should be identical. i.e. `uploads.domain.com` 92 | 93 | You can now access your files as: 94 | `http://uploads.domain.com/uploads/439fbca8-b79b-40e9-8172-4d318737ee14_file.jpg` 95 | 96 | ## That's it! 97 | All done!
