Argo Events S3 Quick Fix - AWS S3 Event Source

Argo Events S3 event source listens for S3 bucket events like object creation or deletion. Misconfigured S3 event sources fail to receive bucket notifications. This guide covers the fix.

Quick Fix

Wrong

s3:
  example:
    bucket:
      name: my-bucket
    events:
    - s3:ObjectCreated:*

The issue: missing endpoint, region, and accessKey configuration. The event source cannot connect to S3 without AWS credentials or endpoint configuration.

Right

s3:
  example:
    bucket:
      name: my-bucket
    events:
    - s3:ObjectCreated:*
    endpoint: s3.amazonaws.com
    region: us-east-1
    accessKey:
      key: accesskey
      name: aws-secrets
    secretKey:
      key: secretkey
      name: aws-secrets

# Expected output after applying the fix
# S3 event source connected to my-bucket in us-east-1
# Listens for s3:ObjectCreated:* events
# Upload triggers event notification
# Event source status: Running

Prevention

• Always configure endpoint, region, and credentials for S3 event sources
• Use Kubernetes secrets for AWS access keys
• Specify granular event types (s3:ObjectCreated:Put, s3:ObjectRemoved:*)
• Configure S3 bucket event notifications to the event source endpoint
• Test with a sample S3 upload before connecting production pipelines
