Cloudflare R2 buckets can be used to store static assets like images and GIFs for the Discourse community, but they cannot be used to store community backups! Introduction: Cloudflare R2 object storage can be used as an alternative to Amazon S3 for storing uploads for your Discourse forum. The fol…

You’re right, I use a Cloudflare R2 storage bucket to store my community’s images, GIFs, and other resources. This greatly reduces the load on the community server and speeds up page loading. I haven’t set up automatic backups for my community to be stored in the Cloudflare R2 storage bucket becaus…

Funny. I thought I’d used R2 for backups before. But perhaps I’m not remembering correctly. You can still follow the recommended instructions and make a note not to put backups there.

Thank you for the reminder, I will highlight this part. Cloudflare R2 buckets can be used to store static assets like images and GIFs for the Discourse community, but they cannot be used to store community backups!

Just to update this post I had some gotchas that needed to be included before cloudflare worked for me. 1. Region shannon: S3 region: You can enter any region, it doesn’t matter for R2. This wasn’t true, I had to use “auto” or the region I selected, auto is easier so use auto. if you nee…

[image] joshhabka: sudo -E -u discourse bundle exec rake s3:upload_assets I did both of those and rebuilt app.yml: ## S3 Configuration DISCOURSE_USE_S3: true DISCOURSE_S3_REGION: auto DISCOURSE_S3_ACCESS_KEY_ID: XXX DISCOURSE_S3_SECRET_ACCESS_KEY: XXX DISCOURSE_S3_CDN_URL: https:…

I think you might have to remove the bucket name from the endpoint. the trailing /xxx should be removed so it’s just .com

Rebuilding and will re-run command, thank you for helping me with this! My app.yml looks like this below now: ## S3 Configuration DISCOURSE_USE_S3: true DISCOURSE_S3_REGION: auto DISCOURSE_S3_ACCESS_KEY_ID: XXX DISCOURSE_S3_SECRET_ACCESS_KEY: XXX DISCOURSE_S3_CDN_URL: https://pub-XXX.r…

I believe all of that is correct. Be sure the the CDN_URL (https://pub-xxx.r2.dev) has public read access so anonymous users can see the assets. You can tell what’s going on in the browsers dev tools. You’ll get a bunch of 403s and red requests in the network tab if the permissions are wrong.
