A playground for building minimal grpc service endpoints in donetcore using featherhttp.

Backlog Phase 1

Theme: Hello world for frontend, Infra

• Get basic working gRPC endpoint running using featherhttp
• Simple unit test
• Dockerize
• Set up basic CI/CD pipeline using github actions
• Enforce PR workflow gated by tests
• Add git versioning https://github.com/dotnet/Nerdbank.GitVersioning
• Dotnetcore cli client
• Bicep for creating ACR infra
• Local docker build works using selfsigned cert with test client
• Release branch push prod container to ACR
• Figure out ACR login via docker
• Fix client-side logging
• Investigate adding code coverage metrics
• Add editor config
• Add service-side logging / tracing
• Add self-signed cert support when hosted on Linux
• Add basic Prometheus metric publishing
• Replace greeter with bi-directional simple streaming ping/pong gRPC
• Helm chart to deploy to K8s
• Add basic health probe
• Script / action to deploy to k3s cluster
• Script / action to deploy to ACI

Backlog Phase 2

Theme: Hello microservice

• Add production SSL cert with Azure keyvault
• Add a backend microsevice (eg a simple in-memory queue)
• Add Open Telemetry Jaeger distributed tracing
• Add Project Tye
• Add OSM support
• Add DAPR support
• Golang client ? Authentication for front end gRPC

Backlog Phase 3

Theme: Moah backend service integration

Dev setup

Pre-requs

• VSCode
• Docker
• dotnet 5 RTM

Steps

1. Build docker image:
   • cd src\BasicService
   • docker build -t feathertestservice:0 .
2. Create self-signed cert (Taken from https://docs.microsoft.com/en-us/dotnet/core/additional-tools/self-signed-certificates-guide)
   • powershell .\localdev\createsscert.ps1
   • Start certmgr
   • Confirm that contoso.com is listed in Trusted Root Certificate Authorities\Certificates
3. Add an entry for contoso.com in hosts file
   • code C:\Windows\System32\drivers\etc\hosts
   • add hosts entry 127.0.0.1 contoso.com
4. Run docker image:
   • docker run --rm -it -p 3000:3000 -p 3001:3001 -e ASPNETCORE_URLS="https://+;http://+" -e ASPNETCORE_HTTPS_PORT=3001 -e ASPNETCORE_ENVIRONMENT=Development -e ASPNETCORE_Kestrel__Certificates__Default__Password="password" -e ASPNETCORE_Kestrel__Certificates__Default__Path=/https/contoso.com.pfx -e Logging__LogLevel__Microsoft=Debug -e Logging__LogLevel__Grpc=Debug -v /c/certs:/https/ feathertestservice:0
5. Run client
   • cd src\BasicClient
   • dotnet run
