The document outlines a continuous deployment workflow utilizing Git and AWS, detailing the integration between a CI server and GitHub for automated builds and package generation via NuGet. It includes a step-by-step guide for configuring and creating EC2 instances on AWS using PowerShell scripts, along with instructions for installing necessary software and managing instances remotely. Key components involve instance creation, configuration, and deployment of applications from the NuGet gallery to AWS infrastructure.

1. Continuous Deployment
GIT to AWS and everything in between.

2. The CI Server – Github to Build
 The CI Server has a project that is connected to a Github repo (1:1 Mapping)
 Each Github repo has a single Solution file (.sln) with multiple projects
(.csproj)
 The CI Server will watch the repo for changes pushed to master and trigger a
build automatically

3. The CI Server – Build to NuGet
 Each build in the CI Server will have logic to generate NuSpec file for libraries
and websites (an existing NuSpec will override the default generation logic)
 The NuSpec file will be ‘pack’ed into a NuGet package for each website,
library, and declared NuSpec file
 Each NuPkg (package) created will be ‘push’ed to the NuGet Gallery
 Library packages will be consumed from gallery while developing code to
share functionality
 Website packages will be downloaded and configured on new ‘computers’ in
AWS

4. AWS – Instance Configuration Example

5. AWS – AMI Configuration

6. AWS –Instance Creation Powershell

7. Creating a new ‘computer’ in AWS
 Two components:
 Configuration file
 Powershell script to create and configure the EC2 instance
 One command will create and fully configure a new instance:
 .AWS-CreateDeployedInstance.ps1 -Credentials $creds -Region 'us-east-1' -
ConfigXml './AWS-Config.xml' -InstanceName 'MyComputersNameInConfig‘
 The application(s) that are to be deployed must exist in the NuGet Gallery
and be specified in the Configuration file

8. AWS – New Instance Steps (AWS API)
 The new instance will be created with the specified AMI (finding latest if
applicable; i.e. latest Windows 2012 R2 AMI from Amazon…)
 The new instance will be named
 The new instance get the specified EBS Volumes (disk drives) and name them
 The new instance will get the specified Elastic IP attached if applicable
 The new instance will get configured with certain necessary components (i.e.
IIS, ASP.NET) and Choclatey NuGet packages (i.e. Chrome, 7-Zip) using
Instance Creation Powershell

9. AWS – Instance Configuration Steps
(WinRM – Remote Powershell Commands)
 When the new instance is running we will install and configure the specified
software (NuGet packages in the private gallery)
 The commands will be executed via WinRM as remote commands to the new
instance
 Any necessary support configuration will be installed (i.e. https certificates)
 Once the packages are downloaded the appropriate mappings in IIS

10. Overview – Code to AWS
DEPLOYMENT POWERSHELL SCRIPT (LOCALLY RUN)
• Terminate existing and creates EC2 instance (uses
AWS API)
• Restart computer to finalize creation tasks
• Invoke remote deployment logic to configure
machine with necessary software
New
Instance
BUILD PROCESS
• Creates new build agent in Azure
• Fetch source from Github
• Build dlls and packages
• Push packages to NuGet Gallery
• Run StyleCop
• Run Unit Tests
NuGet Packages are pulled

11. Overview –
Detailed Deployment
New
Instance
DEPLOYMENT POWERSHELL SCRIPT (RUN LOCALLY)
• Terminate existing EC2 instance if necessary (uses AWS API)
• Creates EC2 instance (uses AWS API), with user data
INSTANCE CREATION POWERSHELL (USER
DATA)
• Install common dev tools via Choclatey
• Rename computer
• Setup WinRM for remote management
• Enable Powershell script execution
DEPLOYMENT POWERSHELL SCRIPT (CONTINUED)
• Names instance and EBS volumes
• Configures EIP if applicable
• Wait for WinRM availability
• Restart computer to finalize creation
• Wait for WinRM availability
• Invoke remote deployment logic
New
Instance
WINRM INVOKED POWERSHELL
• Install IIS and ASP.NET
• Install Certificate (passed through WinRM)
• Download application from NuGet Gallery
• Create AppPool in IIS
• Create Site in IIS pointed to download
user data
Invoke WinRM deployment
Wait for AWS to recognize instance
