PROJECTCON | AGILECON Midwest 2019 in Indianapolis on May 10, 2019 Presenter: Benjamin Day Automated Release Pipelines with Azure DevOps What's DevOps and how do you make it work using Microsoft’s Azure DevOps service? At its core, DevOps is about automating every last thing that you can possibly automate between development and production. Basically, automate away all the annoying & tedious stuff that distracts you from being able to quickly and easily deliver done, working software. This session will be a mix of the practical (75%) and the theoretical (25%). We'll start by talking about the DevOps mindset and why you should even care about DevOps. From there, we'll dive in to the skills and practices you'll need in order to implement an automated, multi-environment DevOps pipeline using Azure DevOps. The demo will to take an existing ASP.NET Core application with automated tests, commit it to Git, create automated builds, and an automated release pipeline that'll take the application from development to test to production.

8. Humans are terrible at multitasking.

9. To be productive,
eliminate distractions.

10. Software delivery not software development.

11. Anything that slows you down,
automate it.

12. Anything that’s painful,
automate it.

13. What is DevOps?

14. DevOps is a mindset plus a set of practices that
focuses on automation.

15. Why DevOps?
Minimize distractions.
Make delivery & deployment easy.

16. Hint:
You want more frequent releases.

17. @benday | www.benday.com
If delivery & deployment is easy…
…it’s not a big deal to do a release
- (Hopefully, without much human involvement)
…you’ll do releases more often
…you can focus more time writing & delivering features

18. Smaller, more frequent releases
 smaller batch size

19. @benday | www.benday.com
Semi-Annual Releases
Large Batch Size
Daily / Weekly Releases
Small Batch Size

20. Smaller, more frequent releases are
easier to manage & less to worry about.

21. (Smaller mistakes.)

22. @benday | www.benday.com
DevOps for
ASP.NET Core & EF Core

23. @benday | www.benday.com
DevOps Goals
Version Controlled, Automated, Repeatable
- Ideally, including hosting environment configuration
- (Docker, ARM templates, etc)
Never deploy from a developer workstation
- No right-click  deploy
Deploy from TFS Build
Deploy from TFS Release Management Pipeline

24. @benday | www.benday.com
ASP.NET Core & EF Core DevOps Checklist
Code is under version control
Database schema & changes are under version control
Automated tests (unit tests, integration tests, UI tests)
Automated build
Automated release / deployment

25. @benday | www.benday.com
DevOps: Don’t Forget the Database!
Does your app use a database?
- You’ll need to version control it
Automated build & deploy of database schemas
Two approaches:
- SQL Server Data Tools (SSDT)
- Entity Framework Migrations

26. DevOps Tip:
Learn how to do everything from
the command line

27. @benday | www.benday.com
Demo:
Manage Your Database
Changes with EF Core Migrations

28. EF Core & EF Core Migrations
Summary

29. @benday | www.benday.com
EF Core NuGet Packages
Talk to SQL Server
Microsoft.EntityFrameworkCore.SqlServer
Database Updates (“Migrations”)
Microsoft.EntityFrameworkCore.Design
Reverse Engineer a SQL Server Database
Microsoft.EntityFrameworkCore.SqlServer.Design

30. @benday | www.benday.com
Enable the “dotnet ef” Command
Edit *.csproj
Add DotNetCliToolReference to
Microsoft.EntityFrameworkCore.Tools.DotNet

31. EF Migrations =
Entity Framework Version Control

32. @benday | www.benday.com
Migrations from the Command Line
Add / Remove a Migration
dotnet ef migrations add “{name}”
dotnet ef migrations remove
Deploy an Update
dotnet ef database update

33. @benday | www.benday.com
Things you need for EF Core
Entity Framework DB Context
- Starting point for all your database operations
- Microsoft.EntityFrameworkCore.DbContext
IDesignTimeDbContextFactory<T>
- Handles creating instances of DbContext for doing migrations
- Microsoft.EntityFrameworkCore.Design.IDesignTimeDbContextFactory

34. Hosting ASP.NET Core on IIS

35. @benday | www.benday.com
Host ASP.NET Core on IIS
Install .NET Core Windows Server Hosting Bundle
- ASP.NET Core 1.*  https://go.microsoft.com/fwlink/?linkid=848766
- ASP.NET Core 2.*  https://aka.ms/dotnetcore.2.0.0-windowshosting

36. Azure DevOps
Builds & Releases 
Azure DevOps Pipelines

37. @benday | www.benday.com
Demo: Azure DevOps Build

38. Monumental Gotcha:
“dotnet ef database update”
assumes that you have the source code…

39. (…and you won’t have your source code
when you do a release.)
