# Dotnet Containerization and Garbage Collection
ℹ️ This example was put together on a Mac using a *nix shell scripts and [homebrew](https://brew.sh) and may not work in other environments.
## Motivation
The intention behind this project is to demonstrate the DATAS memory management optimization in .NET 9 (compared to .NET 8) and how to visualize them using OpenTelemetry.
## Setup
### Install dependencies
```sh
brew install minikube kubectl kustomization k6
```
### Run a local kubernetes cluster
```sh
minikube start --extra-config=kubelet.authentication-token-webhook=false --extra-config=kubelet.authorization-mode=AlwaysAllow
```
*Note: To configure shell to use minikube docker environment, run*
```sh
eval $(minikube -p minikube docker-env)
```
### Build the image
```sh
make build
```
### Verify image is available
```sh
minikube image ls --format table
```
### Setup test environment
```sh
kubectl apply -f ./kubectl/observability
```
### Deploy service and expose endpoint
```sh
make serve_dotnet8 # for dotnet 8
make serve_dotnet9 # for dotnet 9
```
Service is exposed on a random port on localhost. Copy URL and port printed out.
## Run Tests
### Install k6
```sh
brew install k6
```
### Run k6 tests
```sh
k6 run k6/test.js -e MAX_USERS= -e BASE_URL
```
### Access Grafana
```sh
make grafana
```
Login using default user `admin` with password `admin`.
## Teardown
### Reset shell configuration
```sh
eval $(minikube docker-env --unset)
```
