Add a check that CloudWatch Events Rules have <= 5 targets
See original GitHub issuecfn-lint version: (cfn-lint --version) 0.5.0 (but nothing changed since afaict)
Description of issue.
CloudWatch Events has a limit of 10 targets per Rule, but this isn’t validated by ValidateTemplate or cfn-lint’s rules. Consequently one has to wait til deploy time to discover this error message:
CREATE_FAILED: At most 10 targets allowed.
Failing template:
Resources:
MyCronRule:
Type: AWS::Events::Rule
Properties:
ScheduleExpression: cron(0 6 * * ? *)
Targets:
- Id: Job1
Arn: arn:target
- Id: Job2
Arn: arn:target
- Id: Job3
Arn: arn:target
- Id: Job4
Arn: arn:target
- Id: Job5

Thanks. These are the best type of rules for us to add. We’ll get this added.
Thanks for checking that should make things easier. It would have been an odd rule if it was a soft limit.
