EC2 实例未加入 ECS 集群

Question

My EC2 instances are not being shown on ECS cluster but they are appearing on EC2 console. This issue occurs when I specify a different ubuntu image rather than default Amazon image.

Providing the ecs-cli command I used below

ecs-cli up --keypair emaile --capability-iam --size 2 --instance-type t2.medium --launch-type EC2 --image-id ami-03f0fd1a2ba530e75 --cluster-config ec2-cluster --ecs-profile ecs-profile --port 8000

I checked the instances user data and providing you the same

--d9c7ec8c5709925e324f39982c69c71d86d39ec660280837e8a5e69e93c2--

Whenever I try ecs-cli compose up getting the below error

ERRO[0000] Error running tasks                           error="InvalidParameterException: No Container Instances were found in your cluster." task definition=0xc00033e5a0
FATA[0000] InvalidParameterException: No Container Instances were found in your cluster

I think the issue is reproducible, Thanks for help in advance

Ubuntu 18.04 is not on the list of ECS-optimized AMIs. The list only includes AMIs based on Amazon Linux 1, Amazon Linux 2 and Windows.

If you want to use ubuntu, you have set it up yourself to be able to work with ECS. There are some tutorials on how to do it. One example is here .
