Organize your chickens: NuGet for the enterprise

  1. Organize Your Chickens - NuGet for the Enterprise Maarten Balliauw @maartenballiauw RealDolmen
  2. Organize Your Chickens NuGet for the Enterprise
  3. Who am I? • Maarten Balliauw • Antwerp, Belgium • www.realdolmen.com • Focus on web – ASP.NET, ASP.NET MVC, PHP, Azure, … – MVP Windows Azure (formerly ASP.NET) • http://blog.maartenballiauw.be • @maartenballiauw • Author: Pro NuGet - http://amzn.to/pronuget
  4. Agenda • NuGet • Scenarios – Host your own NuGet repository Chickens?! – Continuous Package Integration – Abusing NuGet – NuGet Inception • Conclusion
  5. NuGet
  6. Welcome to Dependency Hell frustration “A term for the of software users who have installed software packages which have dependencies on specific versions of other software packages.” (Wikipedia)
  7. Cause and Effect • Reinventing the wheel – We don’t need that dependency – “If they can do it, we can do it, but better”  What happened to reuse of components? • Marketing-Driven Versioning – People are waiting for v2 to buy – Let’s call it v4 Platform Update SP3 November Edition KB2348063 RTW Refresh  We lost ownership of AssemblyVersion ?
  8. Package Management • NuGet to the Rescue! “NuGet is a Visual Studio extension that makes it easy to install and update open source libraries and tools in Visual Studio.” • Simple concept – Find Packages – (Re)Use Packages – Produce Packages
  9. DEMO Finding & consuming a NuGet package
  10. DEMOpublishing a NuGet package Creating &
  11. Semantic Versioning • Think about your versioning! (semver.org) Major Breaking changes Minor Backwards compatible API additions/changes Patch Bugfixes not affecting the API – Always specify lowerbound – Use a version range (lowerbound + upperbound) when versioning of package you depend on is messed up
  12. Hosting a repository
  13. Hosting your own repository • NuGet = public feed – Privacy – Intellectual property • NuGet maintained by package authors – Author removes v1.0.45 and you depend on it
  14. Solutions • Folder / File share • NuGet.Server package • NuGet Gallery (or Orchard Gallery) • MyGet
  15. DEMO NuGet.Server
  16. NuGet.Server limitations • Only 1 feed per installation • No UI – up to you to build it • No granular security – only 1 API-key for entire feed • Conclusion: requires you to develop if you want something more useful
  17. Meet MyGet • www.myget.org • NaaS – Register and off you go! • Supports Enterprise scenarios – Granular security – Package mirroring – Proxying
  18. DEMO MyGet
  19. Continuous Package Integration
  20. Typical source control... • Contains /References (if you are lucky) – ...and also Project/_bin_deployable_assemblies – ...and also /References/old – ...and also /..././../.././References • Usually references GAC-ed assemblies
  21. Dependencies • Software has dependencies. Deal with it. • But are those YOUR intellectual property? – YOUR reason to build software? – YOUR product? • No. They are dependencies. And they don’t belong in source control.
  22. Continuous Package Integration • Can I get rid of all these referenced assemblies duplicated all-over my source control system? Yes! • Do I need to install and maintain NuGet on all my build agents? No!
  23. DEMO Package Restore
  24. 3rd parties don’t belong in your VCS • Replace them with NuGet packages • Do commit packagesrepositories.config file • Use Enable-PackageRestore
  25. Problem! • NuGet feed is subject to change... – PackageSource msbuild property to the rescue (NuGet.settings.targets in $(SolutionDir).nuget folder) • Now what... – Host your own feed and mirror packages – Or use MyGet for that 
  26. Organize your chickens • Feed structuring – Scoped by quality: Build, QA, Production, … – Scoped by audience: public, restricted access – Other: • Scoped by product version, milestone… • Scoped by target platform
  27. Guidance • Publishing a package brings great responsibility – Breaking changes in your packages should be versioned accordingly! – Consumers might choose to no longer consume any packages you published
  28. Guidance • Package Integration ≠ Integration Testing – CI builds reflect output of source control input – Same input always produces same output  Do not auto-update packages during automated builds
  29. Abusing NuGet
  30. Abusing NuGet? Change of perspective NuGet is a package manager NuGet is a protocol for distributing packages
  31. NuGet as a Protocol
  32. Automate deployments • Build results in .nupkg • Octopus deploys to its tentacles – Test tentacles – Staging tentacles – Production tentacles • www.octopusdeploy.com
  33. Chocolatey • NuGet – developer library packages • Chocolatey – applications and tools packager – “yum” or “apt-get” for Windows • www.chocolatey.org
  34. DEMO Chocolatey
  35. Build Continuous Test Delivery of the MyGet website Package using: Push  TeamCity  NuGet Release / Publish  MyGet Deploy  Octopus DEMO Delivery Continuous
  36. Conclusion Dependencies & people are chickens Deal with them! NuGet can help Set up your own NuGet repository Continuous package integration NuGet is a package manager NuGet is a protocol

Editor's Notes

  1. Maarten
  2. Xavier: Terugverwijzen naar “Marketing versioning”
  3. Start with empty MVC template + addNuGet.ServerpkgRun siteDrop pkgs in packages folderRefresh browserFeed toevoegen in VS & show pkgs
  4. Inloggen en feed aanmakenPackage pushen vanuit NPEFeed toevoegen aan VSOp MyGet feed security instellenPackage installen in VS en tonen dat er basic auth bijkomtPackage van NuGet toevoegen op MyGet en tonen dat je alle dependencies kan meepakken, mirroring, … en dat je ook gewoon van uw packages.config kan toevoegen
  5. - Het feit dat NuGet.org geen garanties biedt op content- Wat als mensen packages verwijderen? BUILD breaks, DEVS unhappy again
  6. Now isnot the time to take a nap (NaaP) NuGet is more than a package (system), it’s a protocol to:Distributesfunctionality (automateanything!, cfrScaffolding!)Distribute websites (akadeployments!)Distribute software in general 
