Hello. We just migrated from Discourse EC2 to Discourse ECS (container service). When we were in EC2, S3 Uploads was not set up yet. Before the migration, we copied all images from EC2 to the S3 bucket (with public access). However, after doing the migration with S3 Uploads enabled (no CDN yet), we noticed that images (and avatars) didn’t load at all. app.yml has: DISCOURSE_USE_S3: true DISCOURSE_S3_REGION: us-east-1 DISCOURSE_S3_ACCESS_KEY_ID: aws_access_key DISCOURSE_S3_SECRET_ACCESS_KEY: aws_secret_key DISCOURSE_S3_BUCKET: DISCOURSE_S3_BACKUP_BUCKET: DISCOURSE_BACKUP_LOCATION: s3 hooks: after_assets_precompile: - exec: cd: $home cmd: - sudo -E -u discourse bundle exec rake s3:upload_assets Running the following in the container didn’t help as well: rake posts:rebake rake posts:missing_uploads rake avatars:refresh We also noticed the difference between the URLs of images (Discourse still used the “local uploads in EC2" URLs). This is the link in S3: https://[s3-bucket].s3.amazonaws.com/original/1X/831092e27d6c066c3618a587a5c378e1c794f2c6.png Link in Discourse (URL still from EC2 uploads): https://[domain]/uploads/default/original/1X/831092e27d6c066c3618a587a5c378e1c794f2c6.png Error in the browser is: 404 NOT FOUND How do we configure Discourse to use the correct S3 URLs for the images?

Hi Jay. Tried executing the command in ECS but encountered an error: [image] Just to ask, should this be ran in EC2 only? Is there another way to migrate uploads or update image URLs? Currently, the EC2 instance is stopped and the current ECS setup uses the domain and database/cache already so I’m not sure if we can point the domain and database/cache back to the old EC2 (then rebuild) without downtime. Thank you.

You’l want to run the command in an instance that has access to the images. Oh, but if you moved them to S3 yourself by hand, then you might want to do some surgery on the uploads table instead. I have been working on a howto with instructions for moving from one bucket to another that you might use to solve your problem, though you’ll need to modify those instructions to account for your local-to-bucket rather than bucket-to-bucket changes. If I were to bill you a flat rate for the job, I’d probably charge 4 hours, though if you were to pay by the hour it might be only one. Oh! Sorry. I just noticed this. If the EC2 is using the same database, then you might be able to crank it back up (leaving the ECS in place), and run the migrate-to-s3 task there; you’ll need to first put all the S3 stuff in ENV variables as described in Using Object Storage for Uploads (S3 & Clones). This is likely the easiest solution. I’d recommend doing a database-only backup before starting.

Hello Jay. Thanks for the response. Got it. I think that will work.

Did you run the migrate to S3 rake task?

I would do that on the ec2 before migrating.
