Cloudflare R2 guide

How to configure Cloudflare R2 and use it in MyFile Share

Create an account on Cloudflare.

Ensure that your domain is added to Cloudflare and verified with NS (Name Server) records on your domain registrar. Your domain has to be hosted through Cloudflare; otherwise, this won't work, and you will be unable to use R2 / Cloudflare CDN to host your images.

While R2 is not free, it does have a generous free tier. The full pricing is available to see here.

To create a bucket:

  1. Open R2.
  2. Select Create bucket.
  3. Type your bucket name of choice, and click Create Bucket.
  4. Select Settings.
  5. Scroll to Domain Access and select Connect Domain.
  6. Type your domain and select Continue.
  7. Select Connect domain.

This connects your domain to the R2 bucket and allows any objects inside that bucket to be accessible by the selected domain.

To create an API token:

  1. Open R2.
  2. Select Manage R2 API Tokens on the top-right side of the dashboard.
  3. Select Create API token.
  4. Select the pencil icon or R2 Token text to edit your API token name.
  5. Under Permissions, select Read or Edit for your token.
  6. Select Create API Token.
  7. Save a copy of your Access Key ID and Secret access key for the next step.

  5. Set Region: to auto.
  6. Fill Bucket name: with the bucket name you picked on Cloudflare.
  7. Change Upload path: to your preference.
  8. Update Use custom domain: to the domain that you selected in the first step.
  9. Uncheck Set public-read ACL on file.
  10. Ignore the rest of the settings.
  11. In Destinations, select Image uploader: and change it to File Uploader -> Amazon S3.
  12. Take a screenshot and ensure that it uploads correctly.
