The document discusses Habitat technology for building, deploying, and running applications in various environments, emphasizing automation and continuous deployment. It covers the workflow for creating and managing containerized applications using Habitat along with AWS services and commands for container setup and management. The text includes links to try Habitat, access tutorials, and explore relevant GitHub repositories.

7. What if you could
defer infrastructure
decisions until
runtime?

8. Habitat
Application automation that enables modern
application teams to build, deploy, and run any
application in any environment - from traditional
data-centers to containerized microservices.

9. Build Service

Build
Service
A Build Service with a workflow to describe the software and behavior for Habitat applications
Explicit about dependencies
Includes what is configurable about the application
Packages are developed and built in an isolated build environment (hab studio)
Built Artifacts are post-processed in one step to multiple formats including Docker Images

16. Applications run as distributed, fully automated, and capable autonomous actors
Immutable applications, but flexible and easy to manage because automation travels
with the application
Bundles what your apps need to run and nothing else (new and legacy)
Embedded automation choreographs application cluster topology/behavior
A network with no reliance on external services and no single-point-of-failure
Provides continuous deployment without traditional Application Release Automation
(ARA) tooling

$ docker images
$ aws ecr create-repository –repository-name mattray/redis
AWS ECR setup

21. $ docker tag mattray/redis:latest aws_account_id.dkr.ecr.ap-

22. $ curl -o ~/bin/ecs-cli https://s3.amazonaws.com/amazon-ecs-
cli/ecs-cli-darwin-amd64-latest
$ chmod +x ~/bin/ecs-cli
$ ecs-cli configure --cluster habitat-demo

instance-type t2.medium --security-group habitat-demo
provisions hosts for containers with SSH, 8080 and Habitat ports open
AWS ECS setup

23. $ aws ecs list-clusters
$ ecs-cli down –force
take down the Cloudformation cluster
$ ecs-cli compose --file redis.yml service rm
remove the deployed service
$ ssh -i ~/.ssh/mattray-apac ec2-user@12.34.56.78
connect to the running ECS host
$ docker logs e1e7834c6ab2
