ECS Service stuck on creation

[Julian-Belcastro]

Hi!

Trying to deploy a CloudFormation template via Serverless gets stuck with 'AWS::ECS::Service' stuck on 'CREATE_IN_PROGRESS' with status 'Resource creation Initiated'.

• Can anyone please tell me if there's a configuration problem with my CloudFormation template?
• How would i troubleshoot this?

Thank you!

Just to clarify (re: above) - we're using this plugin with serverless.yml to create a fargate Task Definition.

We generated the cloudformation template using sls package (it can also be seen in the AWS dashboard).

I suspect it might be this same issue -> (Solution: Service reference TaskDef using ARN?): https://stackoverflow.com/questions/32727520/cloudformation-template-for-creating-ecs-service-stuck-in-create-in-progress
