Working with Amazon EC2 Container ServiceGo to Lab
All the concepts are good. However, while trying to scale the service to 8 instances, it was not able to launch more Container instances at Port 80. Following error received in Events section of ECS Service: service CloudEvangelist-ECS-Demo was unable to place a task because no container instance met all of its requirements. The closest matching container-instance c8fabe91-0e92-46e9-8167-11349f9ee786 is already using a port required by your task. For more information, see the Troubleshooting section.
Step 43, scale up to 8 cannot be reached. It can only scale up to 5 even though desired is 8. Needs to make change in CloudFormation template, and change AsgMaxNode from 5 to 8. Otherwise max instances is limited to 5.
This lab cost 8x as much as the intro, but didn't cover much more material. Practically the same course.
