Getting unhealthy service error

Question

Dear,

I am trying to create my demo ECS service on Farget with public docker image. I tried multiple time but always getting instance unhealthy.

Could you please help me to know where I am doing wrong.

Test data are as follows:
cluster name: **nginx-demo-cl**
task defination: **nginxdemos-hello**
service: **nginxdemos-hello-SVC**
LoadBalancer: **NginxALB**
Target Group: **nginx-tg**
Security Group: **nginxdemos-sg** and **nginxdemos-alb-sg**
docker image: **nginxdemos/nginx-hello**

Answer

Hi,

According to the error message, it seems that you are having problems with the health check. Have you read the following Knowledge Center article about [How to troubleshoot health check failures for Amazon ECS tasks on Fargate?](https://repost.aws/knowledge-center/ecs-fargate-health-check-failures) Your specific error is described and they recommend checking the security group inbound configuration,  ping port value or health check grace period, among other steps.
