ClientException: Family contains invalid characters when using ecs-cli compose

[wjimenez5271]

Trying to launch a docker-compose file that works locally with compose, and I get the following errors:

ecs-cli compose --file docker-compose.yml up
ERRO[0000] Error registering task definition             error=ClientException: Family contains invalid characters.
    status code: 400, request id: 81108bb6-840b-11e5-a881-4de8415be30c family=0xc208036440

Its unclear to me what "Family" its referring to

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).
