Tasks stuck in loop when service discovery is enabled

[ookblah]

When I enable service discovery my tasks go into "activating" status and then stop, get recreated again, etc.

Not entirely sure how to fix, but I was doing some digging and this might be of help. Adding some extra config around healthchecks:

Thanks for the bug report! Could you attach your deployfish.yml so we can try to replicate your issue here?

Sure thing, here's the relevant service from my deployfish.yml and output from the CLI. Don't mind the stuff about traefik. I'm basically spinning up a php service.

#PHP Service
  - name: app
    cluster: cv-staging
    launch_type: FARGATE
    execution_role: <service role arn>
    network_mode: awsvpc
    service_discovery:
      namespace: cv-staging
      name: app
      dns_records:
        type: A
        ttl: 10
    vpc_configuration:
      subnets:
        - <subnet 1>
        - <subnet 2>
      security_groups:
        - <security group 1>
      public_ip: ENABLED
    cpu: 256
    memory: 512
    count: 2
    family: app
    containers:
      - name: app
        image: <php image>
        labels:
          - "traefik.enable=false"
        logging:
          driver: awslogs
          options:
            awslogs-group: cv-staging
            awslogs-region: us-east-1
            awslogs-stream-prefix: app

I'm able to initiate creating the service but then it repeatedly goes into this in my cli before failing deployment. Tasks in the ECS dashboard go into an endless cycle of activating, provisioning, etc. At first glance everything seems to run fine and the service appears to be up, but if you switch to the stopped tasks you see all the dead ones. If I remove the block about service discovery it works fine.
