Docker native

Built in .NET.
Spoken in every language.

Every FileServer module ships as both a NuGet package and an official Docker image — runs on ECS, EKS, Fargate, App Runner, or your laptop. Call its HTTP/gRPC API from Python, Go, Node, Java, Rust, or anything else that speaks the wire.

  • Multi-arch images: amd64 + arm64 from the same tag
  • OpenAPI + gRPC reflection enabled out of the box
  • Same configuration surface — env vars, Parameter Store, file
$ docker pull kanject/fileserver:latest
One NuGet install. Zero glue code.

Kanject.FileServer ships into your AWS, registers itself with one line in Program.cs, and exposes a typed API the rest of your service can use immediately.
