Without Container :

How to pack ?

How to load / unload ?

How to transship ?

How to check dependencies ?

How to protect ?

Container related sessions in re:Invent 2014

Docker is an open platform for developers to build, ship, and run

distributed applications in Linux containers. In this session, Nathan

LeClaire, a Solutions Engineer at Docker Inc., will be demonstrating

workflows that can dramatically accelerate the development and

deployment of distributed applications with Docker containers.

Through in-depth demos, this session will show how to achieve

painless deployments that are both readily scalable and highly

available by combining AWS's strengths as an infrastructure platform

with those of Docker's as a platform that transforms the software

development lifecycle.

If you have tried Docker but are unsure about how to run it at scale,

you will benefit from this session. Like virtualization before,

containerization (à; la Docker) is increasing the elastic nature of

cloud infrastructure by an order of magnitude. But maybe you still

have questions: How many containers can you run on a given

Amazon EC2 instance type? Which metric should you look at to

measure contention? How do you manage fleets of containers at

scale?

Container related sessions in re:Invent 2014

Container technology, particularly Docker, is all the rage these days.

At AWS, our customers have been running Linux containers at scale

for several years, and we are increasingly seeing customers adopt

Docker, especially as they build loosely coupled distributed

applications. However, to do so they have to run their own cluster

management solutions, deal with configuration management, and

manage their containers and associated metadata. We believe that

those capabilities should be a core building block technology, just

like EC2. Today, we are announcing the preview of Amazon EC2

Container Service, a new AWS service that makes is easy to run

and manage Docker-enabled distributed applications using powerful

APIs that allow you to launch and stop containers, get complete

cluster state information, and manage linked containers. In this

session we will discuss why we built the EC2 Container Service,

some of the core concepts, and walk you through how you can use

the service for your applications.

What is container – OS Virtualization

Containers are isolated,

but share OS kernel and,

where appropriate,

bins/libraries

…result is significantly faster

deployment, much less overhead,

easier migration, faster restart

Containers

Make the containers easy to use, standardized,

interoperable

• Container technology has been around for a

while (c.f. LXC, Solaris Zones, BSD Jails)

• Shipping containers are not just steel boxes.

• With Docker, low-level containers get the

following:

- Ease of use, tooling

- Re-usable components

- Ability to run on any Linux server today:

Physical, Virtual, Cloud, …

Docker is a shipping container for codes

Why are customers running Docker in the cloud?

Easy deployments with API

Standardized environment fidelity

Better fleet management

Distributed applications

Cloud is programmable and automated environment

… Good fit to Docker

Task: A grouping of related containers

Nginx Web Server Rails Application

MySQL Database

Log Collector

… about entire architecture not just a container

Task Definition

{ “family” : “my-website”,

“version” : “1.0”

“containers” : [

<<CONTAINER DEFINTIONS>>

]

}

Grouping

Versioning

Container Definition

• Names and identifies your image

• Includes default runtime attributes for your container – Environment Variables

– Port Mappings

– Container entry point and commands

– Resource constraints

– Etc..

… No longer concerned over exact state

Example

{ “name” : “webServer”,

“image” : “nginx:latest”

“cpu” : 512,

“memory” : 128,

“portMappings” : [ { “containerPort” : 9443, “hostPort” : 443 }],

“links” : [“rails”],

“essential” : true

}

Tasks Containers

Clusters Container Instances

Cluster

• Provides a pool of resources for your Tasks

• A grouping of Container Instances

• Starts empty, dynamically scalable

… about underlying infrastructure not just a container

Container Instance

• An instance on which Tasks are scheduled

• Runs AMI with ECS Agent installed

• Registers into cluster on launch

… Forget how to make instance container runnable
