Error occurred during operation 'ECS Deployment Circuit Breaker was triggered"
I am trying to do the workshop https://docs.aws.amazon.com/AmazonECS/latest/developerguide/getting-started-ecs-ec2-v2.html

I already have a task execution IAM role created. I have a user with AdministratorAccess, AmazonEC2ContainerRegistryFullAccess, AmazonEC2ContainerRegistryPowerUser and SecretsManagerReadWrite policies.
the subnet launching the ECS EC2 instances is a public subnet No using ALB.

Hello.
In the case of the EC2 launch type, the container runs on EC2, so you need to check the EC2 security group settings, etc.
From the documentation, it seems that ALB is not necessary, so why are you setting up ALB?
By the way, when using ALB, I think it would be a good idea to change "hostPort" to 80 as shown below and configure the target group to listen on port 80.
