The EventBridge Scheduler is a powerful AWS service that enables you to run one-time or recurring scheduled actions across AWS services or external APIs. With the newly added support for AWS PrivateLink, you can now schedule these actions without requiring internet gateways or NAT gateways, enhancing security and reducing exposure to public networks.
You Should Know:
1. Setting Up EventBridge Scheduler with AWS PrivateLink
To configure EventBridge Scheduler with AWS PrivateLink, follow these steps:
1. Create a VPC Endpoint for EventBridge Scheduler:
aws ec2 create-vpc-endpoint --vpc-id your-vpc-id \ --service-name com.amazonaws.region.scheduler \ --vpc-endpoint-type Interface \ --subnet-ids subnet-123456 subnet-789012 \ --security-group-ids sg-12345678
2. Verify the Endpoint Status:
aws ec2 describe-vpc-endpoints --vpc-endpoint-ids your-endpoint-id
3. Configure IAM Permissions:
Ensure your IAM role has the necessary permissions to interact with EventBridge Scheduler:
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"scheduler:<em>"
],
"Resource": "</em>"
}
]
}
2. Creating a Scheduled Rule with PrivateLink
Use the AWS CLI to create a new schedule:
aws scheduler create-schedule --name "private-schedule" \
--schedule-expression "rate(5 minutes)" \
--target '{"Arn": "arn:aws:lambda:us-east-1:123456789012:function:my-function", "RoleArn": "arn:aws:iam::123456789012:role/scheduler-role"}' \
--flexible-time-window '{"Mode": "OFF"}'
#### **3. Monitoring Scheduled Events**
Check execution logs in CloudWatch:
aws logs filter-log-events --log-group-name "/aws/events/scheduled-rules" \ --filter-pattern '"ERROR" OR "SUCCESS"'
#### **4. Troubleshooting Common Issues**
- Connectivity Errors: Verify VPC endpoint DNS resolution:
dig scheduler.us-east-1.amazonaws.com
- Permission Issues: Check IAM role policies and VPC endpoint policies.
### **What Undercode Say:**
AWS PrivateLink integration with EventBridge Scheduler is a game-changer for enterprises requiring secure, private scheduling of AWS tasks. By eliminating the need for public internet access, organizations can enforce stricter security policies while maintaining seamless automation.
