Container health check for ECS task with awsvpc network mode

Question

Hi,  
  
I'd like to create an ECS task with network mode "awsvpc". The container in the task should have a health check command calling a REST endpoint in the container via curl.  
  
With bridge network mode I'd add the health check command as "CMD,curl,--fail,http://localhost:8080/health/check/endpoint".  
  
However with awsvpc mode, it seems that the container is not reachable via localhost.  
  
How does a healthcheck work if the network mode is "awsvpc"?  
  
Cheers,  
Markus

Answer

Looks like I had to use localhost to connect to the instance.

Hi,  
  
According to the documentation here: https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task_definition_parameters.html#container_definition_healthcheck  
You should be using CMD-SHELL instead of CMD
