Working with Amazon Elastic Container Service Reviews

Kept seeing errors about unable to access Cloud metrics, but the lab created successfully.

Scaling the ECS service in the lab can't exceed ECS instance count of 5 due to port bindings. Suggest modifying lab script to add another task definition and service to see how multiple containers can run on an ECS cluster.

Could only scale up to 5 tasks out of 8. Kept getting the error: "service myservice was unable to place a task because no container instance met all of its requirements. The closest matching container-instance a312bc5e-4657-4c73-8658-b2bfa2bd1735 is already using a port required by your task. For more information, see the Troubleshooting section."

Good high level, but leaves a little something to be desired in terms of the details about each component. Maybe a more complex app and a look at how the clusters are constructed and scaled would be useful.

Lab did not allow you to create 8 tasks since the auto scaling group was maxing at 5 instances. Further the task definitions were mapping to port 80 on the host, meaning that only one container could run per ec2 instance (kind of defeating the point of containers)

good lab. very informative

Nice lab! There were a few things I noticed: - During the last scale up step, there's only one extra instance with a free port, so it wasn't possible to actually scale up to 8 tasks as per the instructions. - The IAM role that wasn't provisioned didn't have access to cloudwatch, which would have been interesting to see.

I did an almost identical lab in an introductory level

not a good value vs the 1 credit introductory, and the only additional part "scaling" is unsuccessful because the pool of container servers is to small to support more than 5 tasks.

The example was suggesting to increase task count beyond the number of available instances. Therefore all tasks could not be launched. I suggest you generate a new Lab that uses Application Load Balancer instead, to allow running multiple tasks on same instance.

wish it explained more details about EC2 containers rather than just relying on magic of cloud formation template

The lab was little confusing in step 27
