3. What is EC2 Container Service (ECS) ?
Anything you can run on EC2 instance can run on
Container in ECS
Supports Docker Containers
Easily run applications on a managed cluster of EC2
instances
Start, Stop, Delete containers

4. EC2 Container Service (ECS) Terminology

5. CLUSTER
Logical group of container instances in AWS region
Start empty, dynamically scalable
Resource Pool

6. Container
Docker container created during task instantiation

7. Container instance
EC2 instance registered to an ECS Cluster
Docker Daemon
ECS Agent

8. Container Agent
registers an EC2 instance to an ECS cluster

9. TASK DEFINITION
One or more containers de nitions to run your application
Shared volume de nitions
Description of application to be deployed

10. Task
De nes what docker container should be launched on an
EC2 instance
Unit of work
Grouping of related containers

11. Service
De nes the desired number of tasks/containers to run
simultaneously in an ECS Cluster

12. Scheduler
Method of placing task on container instance

13. Let's setup

14. Set up ECS cluster

15. Create the task de nition

16. Create an ECS role

17. SET UP AN EC2 CONTAINER INSTANCE WITH THE CONTAINER AGENT INSTALLED AND ADD IT TO THE
CLUSTER
Choose AMI
Choose Instance Type
Con gure Instance
Add Storage
Tag Instance
Con gure Security Group
Review

18. Set up a service based on the httpd container

19. Check whether our EC2 container instance is displaying our
website which we con gured as part of the task de nition

20. Amazon EC2 Container Registry (ECR)
Stores and Manages Docker Images - Source control like
tool for images
No upfront fee, pay only for the data stored

21. Create a repository

22. CONFIGURATION WITH THE CLI
Be a fully managed service with no software to install or
infrastructure to scale.
Integrate with AWS Identity and Access Management
(IAM) to simplify authorization and to provide ne-grained
control.
Transfer container images to and from Amazon EC2
Container Registry via HTTPS.
Support Docker Registry HTTP API V2 allowing you to use
Docker CLI commands or other Docker tools.
Integrate with third-party developer tools through
partners including CloudBees, Codeship, CoreOS,
Mesosphere, Shippable and others.

23. How to Push to and Pull from Amazon EC2 Container
Registry (ECR)

24. Login
aws ecr get-login --region us-east-1
docker login

25. Tag Build
docker tag repositoryName:latest
438574456465345.dkr.ecr.us-east-
1.amazonaws.com/mpatel:latest

26. Push Docker Image
docker push 438574456465345.dkr.ecr.us-
east-1.amazonaws.com/mpatel:latest

27. Pull Docker Image
docker pull 438574456465345.dkr.ecr.us-
east-1.amazonaws.com/mpatel:latest

28. ECS ACCESS TOOLS
AWS Management Console
AWS command line tools
Amazon ECS CLI
AWS SDKs

29. CONTAINER INSTANCE AUTOSCALING
MemoryReservation
MemoryUtilization
CPUReservation

30. Pros of ECS

31. ECS is monitoring status of Docker containers, so if it goes
down it will be deployed automatically

32. ASG is monitoring your EC2 instances, if one instance goes
down, it will spawn new instance

33. ECS can do zero-downtime deployments of new version (Blue
- Green deployments)
Blue - Green deployments means create new
set of containers, which is next version of your
application and bring down previous version
of container then switch over traf c.

34. Updation requires two things
Create new revision of task
Update the revision in the service

35. LIMITS
Number of clusters per region, per account 1000
Number of container instances per cluster 1000
Number of services per cluster 500

36. LIMITS CONT.
Number of load balancers per service 1
Number of tasks per service (the desired count) 1000
Number of tasks launched (count) per run- task 10
Number of container instances per start- task 10
Throttle on container instance registration rate 1 per
second / 60 max per minute
Task de nition size limit 32 KiB
Task de nition max containers 10
Throttle on task de nition registration rate 1 per second /
60 max per minute
