I am running docker containers on an AWS via ECS. I have setup a cluster with some basic configuration.
Now I am looking forward to get no. of all running containers on this cluster (spread across 2-3 EC2 instances)? Does AWS / Docker provide any API for this?
I know on a container instance, doing docker ps -a will return me list of all running / stopped containers, while docker ps will return running containers on one system. But I want an API (which can be called from outside) or command (which I can run on any of the instance part of the cluster) and it shows me total number of running containers across cluster?
