AWS EventBridge

Manage event-driven architectures with EventBridge.

List rules

aws events list-rules --query 'Rules[].{Name:Name,State:State,Schedule:ScheduleExpression,Description:Description}' --output table

Describe rule

aws events describe-rule --name my-rule | jq '{Name, State, ScheduleExpression, EventPattern}'

List targets for rule

aws events list-targets-by-rule --rule my-rule --query 'Targets[].{Id:Id,Arn:Arn}' --output table

Put event

aws events put-events --entries '[{
  "Source": "my.app",
  "DetailType": "OrderCreated",
  "Detail": "{\"orderId\":\"123\",\"amount\":99.99}",
  "EventBusName": "default"
}]' | jq '.Entries[] | {EventId}'

Enable/disable rule

aws events enable-rule --name my-rule
echo "Rule enabled"

aws events disable-rule --name my-rule
echo "Rule disabled"

List event buses

aws events list-event-buses --query 'EventBuses[].{Name:Name,Arn:Arn}' --output table

Notes

• Event patterns and schedule expressions use different rule types.
• Schedule expressions use cron or rate syntax: rate(5 minutes) or cron(0 12 * * ? *).
• Confirm before enabling/disabling rules or sending events.
