Keeping consistent environments across your development, test, and production systems can be a complex task. Docker containers offer a way to develop and test your application in the same environment in which it runs in production. You can use tools such as Docker Compose for local testing of applications; Jenkins and AWS CodePipeline for building and workflow orchestration; and Amazon EC2 Container Service to manage and scale containers. In this session, you will learn how to build containers into your continuous deployment workflow and orchestrate container deployments using Amazon ECS. Learning Objectives: Learn to use the Amazon ECS CLI to test applications locally Orchestrate continuous delivery workflows using AWS CodePipeline Schedule containers on production clusters using Amazon ECS Who Should Attend: Developers, DevOps Engineers

9. Docker and Docker Toolbox
• Docker (Linux > 3.10) or Docker Toolbox
(OS X, Windows)
• Define app environment with Dockerfile

10. Dockerfile
FROM python:2-onbuild
CMD [ "python", "./application.py" ]

11. Docker Compose
Define and run multi-container applications:
1. Define app environment with Dockerfile
2. Define services that make up your app in docker-compose.yml
3. Run docker-compose up to start and run entire app

12. docker-compose.yml
signup:
build: .
ports:
- "80:5000"
environment:
- APP_CONFIG=application.config
- AWS_ACCESS_KEY_ID
- AWS_SECRET_ACCESS_KEY

15. ECS CI/CD Partners

16. Jenkins
Extensible
Flexible builds
• Ant or Maven based projects
• Docker images
Optionally runs in Docker container

17. CloudBees Docker Build and Publish plugin

18. Amazon EC2 Container Registry
Private Docker Repository
• v2 Docker Registry
• IAM and AWS Auth integration
• Low latency push, pulls, and inspection
Alternatives
• Dockerhub
• Docker Trusted Registry

19. Stage 3 - Test

20. Test environment

21. Selenium WebDriver and PhantomJS
import unittest
from selenium import webdriver
class TestSignup(unittest.TestCase):
def test_signup(self):
self.driver.get("http://beta.example.com/#signupModal")
self.driver.find_element_by_id("name").send_keys("My Name")
self.driver.find_element_by_id("email").send_keys("myemail@name.com")
self.driver.find_element_by_id("signup").click()
self.assertTrue(self.find_element_by_id("signupSuccess").isDisplayed()

22. Jenkins
• Run tests directly via Docker run
• Run tests in a Docker slave on Amazon ECS

23. CloudBees Jenkins ECS plugin

24. Jenkins slave Dockerfile

27. Amazon EC2 Container Service
Highly scalable container management service
• Easily manage clusters for any scale
• Flexible container placement
• Integrated with other AWS services
• Extensible
Amazon ECS concepts
• Cluster and container instances
• Task definition and task

28. Amazon ECS CLI
• Easily create Amazon ECS clusters & supporting
resources such as EC2 instances
• Run Docker Compose configuration files on Amazon ECS
• Available today – http://amzn.to/1jBf45a

29. Amazon ECS CLI
> ecs-cli configure --region AWS_REGION --access-key AWS_ACCESS_KEY --secret-key
AWS_SECRET_KEY --cluster default
> ecs-cli compose service create
> ecs-cli compose service up
