Help with DISCOURSE_CDN_URL

Installation
1

I am trying to fix the s3/cdn settings on my site and running into problems. A little back history: I had been using digital ocean spaces with bunny.net for the cdn, I had everything set up properly in the site settings, but I had never set up DISCOURSE_CDN_URL in the app.yml because I didn’t understand how it worked or it’s importance. Recently I switched over to Amazon S3 after I started having issues with DO Spaces, but stuck with bunny.net for the cdn. I think I have that part of the changeover figured out and @pfaffman is going to help me remap the database.

The issue I’m having now is with setting the DISCOURSE_CDN_URL. What I have done is create a new pull zone on bunny for this, set the origin URL to https://community.naturephotographers.network which is my forum. I have a CNAME for this pointing to assets.naturephotographers.network. I then set DISCOURSE_CDN_URL to https://assets.naturephotographers.network and it rebuilds okay, but the assets from the site are not being pulled from the cdn of assets.naturephotographers.network, they are coming from the amazon bucket for some reason.

I tried running this rake task

  after_assets_precompile:
    - exec:
        cd: $home
        cmd:
          - sudo -E -u discourse bundle exec rake s3:upload_assets

But it fails with this error:

Here are my site settings for s3/cdn:

Another interesting side note; if I have all of my s3/cdn settings in my app.yml rather than site settings it breaks my site and I have only a white page despite the settings being exactly the same, with a ton of 403 errors in the console:

  ## S3 Configuration
  DISCOURSE_USE_S3: true
  DISCOURSE_S3_REGION: us-west-1
  DISCOURSE_S3_ACCESS_KEY_ID: ***
  DISCOURSE_S3_SECRET_ACCESS_KEY: ***
  DISCOURSE_S3_CDN_URL: https://images.naturephotographers.network
  DISCOURSE_S3_BUCKET: npnimages
  DISCOURSE_S3_BACKUP_BUCKET: npn-backup
  DISCOURSE_BACKUP_LOCATION: s3

Any ideas? Thank you!

You really have to have them in the ENV vars. In the database won’t do it.
