Generating missing optimized images with S3


After our migration (back) to Amazon S3, we appear to have quite a few images where the optimized versions are missing, but the full-size ones are there (example).

There is a Rake task for regenerating optimized images, but it only appears to work with local storage. How would I do this with remote images?

A question for @zogstrip I think!


Still waiting for an update on this.

We have some quite noticeable missing post images, and had at least one broken scaled avatar…

I’m afraid you’ll have to write your own rake task for that. Here’s some pseudo code on how I’d start

FOR EACH oi IN optimized_images
   IF file_exists_on_s3?(oi.upload.url) AND NOT file_exists_on_s3?(oi.url) THEN
       OptimizedImage.create_for(oi.upload, oi.width, oi.height)
   END IF

@uppfinnarn Did you manage to solve this?

I just migrated to S3, and indeed the /optimized/ folder is not transferred in the migration. I’d like to get rid of the /optimized/ folder, as it adds significant weight to my daily backup.

How big is your Discourse backup?

I’m not sure if the following is complete, but this rails console command brute-forces them all:

UserAvatar.all.each {|ua| uaid = ua.gravatar_upload_id || ua.custom_upload_id; Jobs::CreateAvatarThumbnails.perform_async(upload_id: uaid) if uaid }
