ECS - Elastic Container Service

· ECS is a container orchestration service

· ECS facilitates the running of Docker on EC2

· ECS is complex and can consist of

o ECS core: user provisioned running on EC2 instances

o Fargate : ECS Tasks running on AWS compute ( serverless )

o EKS: ECS running on AWS-powered by Kubernetes (running on EC2)

· ECS Cluster: set of EC2 instances

· ECS Service: applications definitions running on ECS Cluster

· ECS Tasks & Definitions: containers running to create the application

· ECS IAM Roles: roles assigned to tasks to interact with AWS

ECS Config

· Run an EC2 instance, install the ecs agent and config file

· OR use a ready Linux ECS-ready Linux AMI ( still have to modify the config file)

· ECS Config file is at /etc/ecs/ecs.config

· ECS (Elastic Container Service): Docker container management system on AWS. Helps with creating micro-services.

· ECR (Elastic Container Registry): Docker images repository on AWS. Docker Images can be pushed and pulled from there
