2. Distributed deployments
Agenda
What is CodeDeploy?
Start with a 10 minute introduction to OpenWhere. Help to understand the context of our experience with Cloud, Continuous Delivery. We talked our capabilities, experiences, and philosophy.
Next we do a quick introduction to Docker
Outline our Continuous Delivery Pipeline with AWS & Docker
Wrap up with lessons learned
We can do a demo if time permits and have a discussion
Distributed deployments
with CodeDeploy
Demo & Discussion

3. What is CodeDeploy?

4. What is CodeDeploy?
“AWS CodeDeploy is an AWS service that coordinates application deployments to instances”
Yet another deployment tool

5. Why CodeDeploy Not meant to replace other Continuous Integration tools
Many CI tools have CodeDeploy plugins / hooks
Jenkins
Elastic Beanstalk
Chef
Puppet

6. CodeDeploy benefits Automated Deployments Minimize Downtime
Consistently deploy across multiple environments
Scales with infrastructure
Minimize Downtime
Rolling updates across instances
Application health tracking
Deployment rollback
Centralized Control
Web and CLI console for status tracking
Detailed reporting
Easy to Adopt
Reuse existing software setup and deployment processes
Platform agnostic

7. Typical Deployment Flow

8. Getting Started with CodeDeploy
IAM Role Setup
Deployment Application
Name
Revision
Deployment Group
Service Role
Deployment Configuration

9. Application Deployment Planning

10. Deploying a Revision Planning a revision deploy Copy source files
Running scripts
Copy source files and run scripts
Adding an AppSpec YML file
Pushing the revision

11. What is the AppSpec YML ? Descriptor file that directs CodeDeploy
Unique to CodeDeploy
File must be named appspec.yml
Each revision must contain one and only one file
Must be added to the root directory of the deployment content

12. AppSpec Sections Version – AWS / CodeDeploy specific.
OS – Target operating system
Files – Source / Destination mappings
Permissions – File ownership and permissions
Hooks – Entry points for executing scripts

13. AppSpec: Deployment Hooks

14. AppSpec example os: linux files: - source: Config/config.txt
destination: webapps/Config
- source: source
destination: /webapps/myApp
hooks:
BeforeInstall:
- location: Scripts/UnzipResourceBundle.sh
- location: Scripts/UnzipDataBundle.sh
AfterInstall:
- location: Scripts/RunResourceTests.sh
timeout: 180
ApplicationStart:
- location: Scripts/RunFunctionalTests.sh
timeout: 3600
ValidateService:
- location: Scripts/MonitorService.sh
runas: codedeployuser

15. Deployment Layout /tmp/ or c:\temp (root folder)
|--content (subfolder)
| |--myTextFile.txt
| |--mySourceFile.rb
| |--myExecutableFile.exe
| |--myInstallerFile.msi
| |--myPackage.rpm
| |--myImageFile.png
|--scripts (subfolder)
| |--myShellScript.sh
| |--myBatchScript.bat
| |--myPowerShellScript.ps1
|--appspec.yml

16. Validating AppSpec files
Any online YML parser

17. Pushing Revisions Revisions locations: S3 / GitHub CodeDeploy console
Command line pushing
aws deploy create-deployment \
--application-name CodeDeployGitHubDemo-App \
--deployment-config-name CodeDeployDefault.OneAtATime \
--deployment-group-name CodeDeployGitHubDemo-DepGrp \
--description "My GitHub deployment demo" \
--github-location repository=repository,commitId=commitId

20. Supported Operating Systems
EC2 Tested Operating Systems
Amazon Linux ,
Ubuntu Server LTS
Windows Server 2008 R2 and 2012 R2
On-premises instance operating systems
NOTE: the AWS CodeDeploy Agent is available as open source for adaptation to other Amazon EC2 AMI operating systems.

21. Supported AWS Regions Currently available in the following regions
US East (N. Virginia)
US West (Oregon)
EU (Ireland)
Asia Pacific (Sydney)
NOTE: CodeDeploy performs deployments to resources in the same region
For multiple region deploys, the application bundle must be available in an accessible S3 bucket or GitHub repository

22. What about Auto Scaling?
Create new Deployment Group for the application and select an Auto Scaling Group

23. Costs
No additional cost for EC2 instances
$0.02 per on-premise instance
