Expected Behaviour

The ufo ship command should deploy the ECS service without any issues, creating the necessary ECS cluster and running the tasks as expected.

Current Behavior

The ufo ship command gets stuck at the ECS service creation step, displaying the error message:

CREATE_IN_PROGRESS AWS::ECS::Service EcsService Eventual consistency check initiated

The error in AWS reads:

service demo-web-dev-EcsService-QY7NEm2trctk was unable to place a task because no container instance met all of its requirements. Reason: No Container Instances were found in your cluster. For more information, see the Troubleshooting section of the Amazon ECS Developer Guide.

Step-by-step reproduction instructions

1. Install UFO:

   gem install ufo

2. Set up AWS config and credentials:

   # ~/.aws/config
   [dev]
   region = us-west-1
   output = json
   
   # ~/.aws/credentials
   [dev]
   aws_access_key_id=REPLACE_ME
   aws_secret_access_key=REPLACE_ME

3. Set AWS_PROFILE and verify credentials:

   export AWS_PROFILE=dev
   aws sts get-caller-identity
   aws s3 ls

4. Create ECS cluster named dev in the us-west-1 region:

   aws ecs describe-clusters --clusters dev --region us-west-1 --profile dev

5. Set up the demo project:

   mkdir demo && cd demo
   aws ecr create-repository --repository-name demo
   REPO=$(aws ecr describe-repositories --region us-west-1 --profile dev --repository-name demo | jq -r '.repositories[].repositoryUri')
   echo $REPO
   AWS_PROFILE=dev ufo init --app demo --repo $REPO

6. Ship the code:

   AWS_PROFILE=dev ufo ship -y

7. Observe the error:

   CREATE_IN_PROGRESS AWS::ECS::Service EcsService Eventual consistency check initiated
