Bunny.net CDN (Pull Zone)

Stage 1: Setup Pull Zone

1) Add new pull zone in Bunny.net

2) Create a unique name for the pullzone

Example: mastodoninstancestatic or similar.

3) Select Origin Type URL

4) Update Origin URL

Place the original FQDN of your instance in the Original URL.

5) Select your regions to replicate data

6) Add new Pull zone

Stage 2: Configure Pull Zone.

1) Force SSL

2) Setup SafeHop (retries on failures)

3) Add additional Headers (CORS)

Add `,js, gz` to the Extension list.

Example: `eot, ttf, woff, woff2, css, js, gz`

Stage 3: Configure Mastodon and NGINX

1) NGINX Headers

Add Access-Control-Allow-Origin header to nginx all locations. Example: add_header Access-Control-Allow-Origin "https://aussocialstatic.b-cdn.net";

2) Mastodon .env

Add CDN_HOST to .env.production

Example: CDN_HOST=https://aussocialstatic.b-cdn.net

3) Reload nginx and restart mastodon.

Troubleshooting

The OCR (Optical character recognition) might fail if you missed gz from the extension list.

Notes

Do we need to add to svg to the CORs?
