Cloud Formation - skip creation if resource exists

Question

I'm creating CF template and I would like to use Conditions to check if resource not exists else proceed with next steps. The error that I am getting is
```
Resource ApplicationName/application.log already exists.
```
Would the community have an input?

Description: CloudWatch log groups used by application
  ApplicationLogGroup:
    Properties:
      LogGroupName: ApplicationName/application.log
      RetentionInDays: 545
    Type: AWS::Logs::LogGroup

Answer

If you're trying to check for some existing resources into CF, it is unfortunately not available.
Instead you can use conditions and control the resource creation.
For log groups in the first iteration you could delete the log group and provision the stack, from the next iteration it would be update operation so there would be no issues.
