ClientException: Family contains invalid characters when using ecs-cli compose about amazon-ecs-cli HOT 4 CLOSED

Thanks for reporting, we will add better error messaging.

Family refers to the name of the ECS Task Definition that this tool creates by translating the docker compose yml.
http://docs.aws.amazon.com/AmazonECS/latest/developerguide/task_definition_parameters.html#family

We autogenerate the family name using the --project-name flag that is passed to ecs-cli compose, which defaults to the directory name you are running this command from. Acceptable characters for the project-name are letters (uppercase and lowercase), numbers, hyphens, and underscores.

@uttarasridhar thanks, that's helpful, I was able to get around the issue by specifying a the project name manually (with a valid name).

I am following the naming convention for the family key in the task definition json when I am using aws-cli. But I am still getting this error

An error occurred (ClientException) when calling the DescribeTaskDefinition operation: Family contains invalid characters.

 aws ecs describe-task-definition --task-definition .aws/task-definition.json --debug

Using this command.
