Is Hetzner Object Storage and Bunny CDN Supported?

[Zomphie]

Hello. Do you support Hetzner Object Storage and Bunny CDN? I am not able to get these to work correctly.

I do see that the S3 region does not support the region I need, which is Falkenstein. How do we enable this region?

Hetzner Object Storage

I’m not too sure about this. The list doesn’t contain Hetzner.

@Zomphie

Bunny CDN

Yep, it is:

Hello. Thank you for your reply, Nate. So, we were able to get the S3 Hetzner Object Bucket to work, but we were not able to get the Bunny CDN to work at all. When we had the Bunny CDN enabled, the website would not load. It was stuck on the loading screen Discourse gives you.

Hmm… did you follow these guides?

Enable a CDN for your Discourse

So you’d like to use a CDN to speed up worldwide access to common assets on your Discourse forum? You might want to go all-in and Set up file and image uploads to S3 (see also Configure an S3 compatible object storage provider for uploads). If you want a CDN without the added complexity of S3 and having two CDNs, this is the guide for you. The CDN will reduce some load on your server by letting the CDN serve those assets so that the server doesn’t have to. It also can speed things up by deliver…

Full site CDN acceleration for Discourse

Fastly , CloudFlare and a few other CDNs offer a mode where they accelerate dynamic content. In a nutshell you point your domain IP address at the CDN and the CDN will intelligently decide how to deal with the request. Static content can be easily served from cache Dynamic content can be routed to the site. This provides some advantages over only shipping static assets which is covered in the CDN howto. You can elect for “shielding” that protects your site from traffic spikes. Dynamic cont…

When setting the DISCOURSE_S3_CDN_URL, all asssets are being requested from that host, which includes the start-discourse javascript file as well as other .js files. In some posts, it suggests setting the DISCOURSE_CDN_URL to the same host as the server running Discourse to avoid that, however doing so the .js files are still requested through the same host as the DISCOURSE_S3_CDN_URL.

No, we did not run the upload_assets command afer building the app, because we did not want to upload the .js files to the CDN, we ideally only want to have uploads in the S3 bucket and we don’t want any assets hosted on the CDN otherwise.

That’s not how it works.
You upload assets to S3 and then the CDN will pull them from S3.

We now have this working.

Can you share what made it work?

[Zomphie]

Hello! I hope this helps, if you are still not clear on this, please let me know and I will rewrite this to make more sense.

In app.yml set:

env:
  DISCOURSE_S3_CDN_URL: [BUNNY CDN]

Then after the app was rebuilt, we ran:

sudo ./launcher enter app
rake s3:upload_assets
exit

[!] I can confirm, Hetzner Object Storage does work with S3.
