Cluster Management Made Easy

No cluster software to install and manage

Manages cluster state

Manages containers

Control and monitoring

Scale from one to tens of thousands of containers

Scalable

Flexible Container Placement

Applications

Batch jobs

Multiple schedulers

Designed for use with other AWS services

Elastic Load Balancing

Containers are natural for services

Simple to model

Any app, any language

Image is the version

Test & deploy same artifact

Stateless servers decrease change risk

Task definitions

Processes that run together on the same instance

Scale in tandem

May share common resources such as files, or links

Often exposed through one endpoint

Walk through

Typical user workflow

I want to run a service


Run Instances AmazonEC2

Use custom AMI with Docker support and ECS Agent. Instances will register with default cluster.

ECS CLI

High-level commands to simplify creating, updating, and monitoring clusters and tasks

Supports Docker Compose, a popular open-source tool for defining and running multi-container applications

Binaries available for Mac OSX and Linux

Open source, download, comment https://github.com/aws/amazon-ecs-cli

Create an ECS cluster

Creates all the resources required by your cluster in one command

$ ecs-cli up --keypair id_rsa --capability-iam --size 2 --instance-type t2.medium INFO[0000] Created cluster cluster=ecs-cli-demo INFO[0000] Waiting for your cluster resources to be created INFO[0001] Cloudformation stack status stackStatus=CREATE_IN_PROGRESS

Docker Compose

Model multi-container services

Run on desktop and AWS

Store in source control

web: image: amazon/amazon-ecs-sample ports: - "80:80"

Run Compose Locally

Run Compose on the local dev environment

$ docker-compose upCreating compose_web_1...Attaching to compose_web_1

Deploy the Compose File to an ECS Cluster

Can run stand-alone tasks or create an ECS service

$ ecs-cli compose service up INFO[0000] Using ECS task definition TaskDefinition=ecscompose-cli-webinar:1INFO[0000] Created an ECS Service serviceName=ecscompose-service-cli-webinar taskDefinition=ecscompose-cli-webinar:1INFO[0000] Updated ECS service successfully desiredCount=1 serviceName=ecscompose-service-cli-webinarINFO[0000] Describe ECS Service status desiredCount=1 runningCount=0 serviceName=ecscompose-service-cli-webinar

View the Running Containers

View what you created

$ ecs-cli service ps Name State Ports TaskDefinition46163c8a-fd75-481d-a670-1bda9f433493/web RUNNING 52.91.66.37:80->80/tcp ecscompose-cli-webinar:1

Scale your service

Add more tasks to scale the service

$ ecs-cli compose service scale 2INFO[0000] Updated ECS service successfully desiredCount=2 serviceName=ecscompose-service-cli-webinarINFO[0000] Describe ECS Service status desiredCount=2 runningCount=1 serviceName=ecscompose-service-cli-webinar

Update your service

Change docker-compose.yml to include an nginx proxy and redeploy

$ ecs-cli compose service upINFO[0000] Using ECS task definition TaskDefinition=ecscompose-cli-webinar:2INFO[0000] Updated the ECS service with a new task definition. Old containers will be stopped automatically, and replaced with new ones desiredCount=2 serviceName=ecscompose-service-cli-webinar taskDefinition=ecscompose-cli-webinar:2INFO[0000] ECS Service has reached a stable state desiredCount=2 runningCount=2 serviceName=ecscompose-service-cli-webinar
