Where are Docker images are stored?

• Docker images are stored in Docker Repositories
• Public
  • Docker Hub
• Private
  • Amazon ECR (Elastic Container Registry)

Docker Containers Management

• To manage containers, we need a container management platform
• ECS (Elastic Container Service): Amazon's own platform
• Fargate: Amazon's own serverless platform
• EKS (Elastic Kubernetes Service): Amazon's managed Kubernetes

ECS Clusters

• ECS Clusters are logical grouping of EC2 instances
• EC2 instances run the ECS agent (Docker container)
• The ECS agents registers the instance to the ECS cluster
• The EC2 instances run a special AMI, made specifically for ECS

• When you create a ECS Cluster it comes out with a ASG (with one EC2 instance running)
