FOR SERVICE PROVIDERS

Migrating Providers/Backends

If you want to move data between providers (e.g., from your disk to AWS or GCS), do the following:

1. Set AUDIUS_STORAGE_DRIVER_URL_MOVE_FROM (in audius-docker-compose/creator-node/override.env) to your current provider (most likely local disk - "file:///tmp/mediorum/blobs").
2. Set AUDIUS_STORAGE_DRIVER_URL to the new provider (see below for configuration and to make sure you have the right credentials).
3. Start the server and monitor logs for errors. Once you see the message "Finished moving files between buckets" and the health check responds again, then the migration is complete. NOTE: this may take hours to complete.
4. Remove the AUDIUS_STORAGE_DRIVER_URL_MOVE_FROM env var and restart the server. You're good to go!

Configuring GCS Backend

1. Createa new Service Account and JSON key for it. scp the key onto your server and mv the key to /var/k8s/mediorum/google-application-credentials.json.
2. Create a GCS bucket:
   • Non-public access (enforce public access prevention)
   • Uniform access control
   • No protection tools
3. In the bucket permissions, grant access for Storage Legacy Bucket Owner and Storage Legacy Object Owner for the Service Account (set the principal to the Service Account’s email).
4. Set these env vars in audius-docker-compose/creator-node/override.env:
   • GOOGLE_APPLICATION_CREDENTIALS="/tmp/mediorum/google-application-credentials.json"
   • AUDIUS_STORAGE_DRIVER_URL="gs://<your bucket's name>"

Configuring AWS Backend

1. Ensure that you block public access for your bucket.
2. Create an IAM policy for the bucket with these minimum permissions:
   • Under Read choose GetObject and GetObjectAttributes.
   • Under Write choose DeleteObject and PutObject.
   • Under List choose ListBucket.
   • Click Add Arn, enter the bucket name, and check the box for Any object name.
3. Make an IAM user and group with this policy, and in the user/group click “Create access key” and select “Third-party service.”
4. Set the environment variables in your node’s audius-docker-compose/creator-node/override.env file accordingly:
   • AWS_ACCESS_KEY_ID
   • AWS_SECRET_ACCESS_KEY
   • AWS_REGION
   • AUDIUS_STORAGE_DRIVER_URL="s3://<your_bucket_name>"

Status + Run it

• make tools - install tools (make sure ~/go/bin is in path)

• make pg.bounce - starts postgres via docker-compose

• make - starts single process dev cluster

• make test

visit http://localhost:1991/

with make dev2 you can use goreman to start and stop servers:

• make dev2 - starts servers as separate processes
• goreman run stop m2
• goreman run start m2

Uploading a test file:

curl -v -XPOST -F template=audio -F files=@steve_drunk_bass.mp3 http://localhost:1991/uploads

Docker

docker build . -t mediorum
docker run -it -p 1991:1991 mediorum

Deploy

• make build.fast
