I configured minio as image upload storage, it works well for new uploads, but I can’t migrate olds into that.
root@9c9267547230:/var/www/discourse# rake uploads:migrate_to_s3
Migrating uploads to S3 for 'default'...
Some uploads were not migrated to the new scheme. Please run these commands in the rails console
SiteSetting.migrate_to_new_scheme = true
Jobs::MigrateUploadScheme.new.execute(nil)
when I execute Jobs::MigrateUploadScheme.new.execute(nil) first time, it takes several hours and returned some exception, but seems finally success.
I think It should be possible to manually transfer upload files from local to minio by minio client (mc). Then update links by a rake task. However I didn’t try it cause I cant risk it on my community.
In your case if its only a handful of site icons, maybe just upload them manually and update links in your dashboard.
The problem that I think he was referring to is that migrate_to_s3 won’t run unless everything has been changed to the new scheme but the default/stock images are in the old scheme. And the process that updates them didn’t touch the stock images. (and if you run an update they get recreated)
