Continuous Delivery: Reliable Software Releases Through Build, Test, and Deployment Automation
Jez Humble, David Farley

Why NOW?

  • Most CI talks ignore the Deployment problem or fail to provide repeatable steps
  • Nuget
  • Powershell

CI – Continuous Integration

  • Reduce Risk, Fail fast, Learn Fast
  • Allows you to scale software development from 1 dev to 100+ devs
  • Popular Packages: TeamCity, TFS TeamBuild, cloud providers
  • Bad processes can cost a company $25 day per developer. $6,500 yr per developer; Average team size (5): $32,500/yr of waste

CI – Integration Problems 101

  • Distributed teams + Zero shared infrastructure
  • DevId - Each developers should be able to run code locally
  • DevEnvironment - Each developer should be able to run software without shared infrastructure
  • DevBranch - Each developer should be able to work on multiple branches at the same time
  • DevTask – UI designers / integration (mocked services)
  • DevProduct – gold/silver/bronze/; C1/C2/C3/C4

CI – How it looks

continious integration

CI – Configuration Risk

  • XDT - Web.config Transformations – To handle DevId, DevEnvironment, DevBranch, DevTask, DevProduct – would require to many files to handle all possible permutations using baked in VS2010 support.

2009-2010 – FlexibleConfig – built with NPEG

CI – Database Change Management

  • Database Change Management (.sql): 00006-register-RobustHaven.SqlClr.sql Roundhouse, RH DbChangeManagement

Backup, restore, change management, obfuscate
database migration
database backup
Database prefix
Local requires branch name (devs working on multiple branches)
Staging environments – test/general/future do not – always on one branch of the code – so branch is not used

CI – Infrastructure Change Management

  • Infrastructure Change Management (.ps1): 0001-surveybinding-FlatRock.ENV.production.NODE.srvweb1.srvweb2.ps1
Infrastructure Change Management

CI Staging Environments

Hyper-V - sysprep (IIS/MSMQ/Window Services)

MSBuild vs PSake

msbuild psake

MSBuild the good

  • MVCContrib portable areas – Embedded Resources embedded resources
  • NSeviceBus – generic host NServiceBus generic host

CI – Triggering Practices

  • On checkin - vcs to build & test
  • Scheduled for nightly automated integration tests
  • Schedule for production like sync
  • Trigger dependencies to build
  • CI – Build, Test, Obfuscate, Package, Create artifacts consumed by CD environment
  • Manual Trigger - deploy

CD – Continuous Deployment

continuous deployment
  • Web Deploy + Web Farm Framework #FAIL
  • Udeploy - Expensive
  • Thoughtworks GO
  • Octopus Deploy
    • Redgate Deployment Manager – Fork of old version of Octopus Deploy
  • Chocolatey

Octopus Deploy

  • Octopus Server
    • Radiates Information on dashboard
  • Nuget Packages, Nuget Server
  • Tentacle Agent
    • Responsible to deploy on specific machine
  • REST API – Octopus-Tools (github)
    • CI – auto deploy to staging environments and production

Octopus Deploy Server – How it looks

octopus deploy octopus deploy
Migrating Octopus Server:
Raven.Smuggler.exe in
http://localhost:10930/ c:\file.octobak

Link Servers to ENV and Roles

CD Steps

  • Window Services (NServiceBus / TopShelf)
  • Websites (IIS individual appdomain)
  • LanguageWorkbench
    • (non iis or winservice)
action
scripts

CD Vars

              http://octopusdeploy.com/documentation/features/variable

Nuget Packages

nuget nuget
nuget nuget
Promote-deployment

Nuget Server

  • Initially use Nuget package – File based server
  • If you are storing a lot of packages for a long period of time – Lucene version - Klondike
  • TeamCity
nuget

Tentacle Agent

tentacle tentacle
-w c:\workingdirectory

REST API – Ties CI with CD

Octopus Deploy (411)

  • Octopus Documentation
  • Octopus Blog - #RFC on features, Ideas, dev topics
  • https://github.com/OctopusDeploy
  • @octopusdeploy
  • @paulstovell
  • @stevenkuhn
octopus

ETL process – Nation Wide

  • Octopus Deploy –
    • Great when you manage all the infrastructure
    • Great for dashboard that radiates visibility of deployments for everyone (testers, devs, business)
    • Octopus Deploy V2 when dealing with 3rd party infrastructure due to Firewall (push/pull)
  • Chocolatey – No need to open firewall. No central server that radiates information.

Azure Cloud – xpat-cli

Powershell -> xplat-cli -> to use jq.exe
You don’t need Octopus Deploy – however I like a centralized dashboard, high level orchestration, 1 tentacle deploying with apis only octopus
