• Best practices for containers in continuous delivery solutions

• Toolset to implement such solutions

• Demos

Why use containers?

• Process isolation

• Portable

• Fast

• Efficient

Why use containers for continuous delivery?

• Roll out features as quickly as possible

• Predictable and reproducible environment

• Fast feedback

Demo application architecture

Test environment

Deployment environment

Source

Stage 1 - Source

Development environment

Code repository

Source

Docker and Docker Toolbox

• Docker (Linux > 3.10) or Docker Toolbox (OS X, Windows)

• Define app environment with Dockerfile

Dockerfile

FROM python:2-onbuildCMD [ "python", "./application.py" ]

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

docker-compose.yml

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

Stage 2 - Build

ECS CI/CD Partners

Jenkins

Extensible

Flexible builds• Ant or Maven based projects• Docker images

Optionally runs in Docker container

CloudBees Docker Build and Publish plugin

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

Stage 3 - Test

Test environment

Test environment

Selenium WebDriver and PhantomJS

import unittestfrom 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()

Jenkins

• Run tests directly via Docker run

• Run tests in a Docker slave on Amazon ECS

CloudBees Jenkins ECS plugin

Jenkins slave Dockerfile

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

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

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

It’s Dem-o-clock!

Thank you!
