Using Docker to supercharge .NET development on Linux

My presentation from DDD Sydney 2017, held at UTS Sydney in July. Note that this talk is slightly different from the one at Fringe as it is longer, more detailed and a little heavier on the demos.

1. USING DOCKER TO SUPERCHARGE .NET DEVELOPMENT ON LINUX Alistair Chapman @agc93 1
2. DOCKER + .NET CORE + LINUX = 2
3. AGENDA Introduction Building with Docker Building for Docker Being a magpie developer 101 3
4. INTRODUCTION Alistair Chapman agc93 agc93 4
5. A NOTE ON MOVING TARGETS 1.1 2.0 Preview 5
6. DOCKER Process and environment isolation Supported on Linux, Windows (mostly) and macOS (sort of) Currently undergoing a minor identity crisis .NET CORE The next generation of the .NET platform Supported on Windows, macOS (mostly) and Linux (sort of) Currently undergoing a minor identity crisis 6
7. .NET CORE ON LINUX THE BARE ESSENTIALS 7
8. ADDING DOCKER TO THE MIX Use a Dockerfile to build an image You can then run your image to run your app in a container Your base image decides the environment FROM microsoft/dotnet:1.1.2-sdk COPY . /app WORKDIR /app RUN ["dotnet", "restore"] RUN ["dotnet", "build"] EXPOSE 5000/tcp CMD ["dotnet", "run", "--server.urls", "http://*:5000"] 8
9. ADDING DOCKER TO THE MIX Dockerifying a basic .NET app 9
10. BUILDING WITH DOCKER USING CONTAINERS FOR .NET BUILDS AND TESTS 10
11. BUILDING WITH DOCKER Docker containers provide: Isolation "Clean" environment Deterministic builds Containers won't provide: "Real-world" usage Security for untrusted code* Compatibility guarantees 11
12. BUILDING FOR DOCKER DOING WHAT THE COOL KIDS DO BUILDING CLOUD-NATIVE APPS IN CONTAINERS 12
13. BUILDING FOR DOCKER 13
14. BUILDING FOR DOCKER 14
15. BUILDING FOR DOCKER 15
16. WHERE TO NEXT? Try it out for yourself Check out Windows Containers Develop further with schedulers Host on your platform of choice 16
