## Installing
### Using ingress-nginx
```shell
kind create cluster --image kindest/node:v1.27.3 --config=kind/cluster.yaml
helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
helm install ingress-nginx/ingress-nginx --name-template ingress-nginx --create-namespace -n ingress-nginx --values kind/ingress-nginx-values.yaml --version 4.8.3 --wait
helm install sample-app/helm-charts/ingress-nginx --name-template sample-app --create-namespace -n sample-app --wait
helm upgrade sample-app sample-app/helm-charts/ingress-nginx -n sample-app --reuse-values --set canary.weight=50 --wait
```
### Using argo-rollouts
```shell
kind create cluster --image kindest/node:v1.27.3 --config=kind/cluster.yaml
helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
helm install ingress-nginx/ingress-nginx --name-template ingress-nginx --create-namespace -n ingress-nginx --values kind/ingress-nginx-values.yaml --version 4.8.3 --wait
helm repo add argo https://argoproj.github.io/argo-helm
helm install argo/argo-rollouts --name-template argo-rollouts --create-namespace -n argo-rollouts --set dashboard.enabled=true --version 2.32.5 --wait
helm install sample-app/helm-charts/argo-rollouts --name-template sample-app --create-namespace -n sample-app --wait
kubectl argo rollouts dashboard -n argo-rollouts &
kubectl argo rollouts set image sample-app sample-app=ghcr.io/jhandguy/canary-deployment/sample-app:latest -n sample-app
kubectl argo rollouts promote sample-app -n sample-app
```
### Using argo-rollouts + prometheus
```shell
kind create cluster --image kindest/node:v1.27.3 --config=kind/cluster.yaml
helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
helm install ingress-nginx/ingress-nginx --name-template ingress-nginx --create-namespace -n ingress-nginx --values kind/ingress-nginx-values.yaml --version 4.8.3 --wait
helm repo add argo https://argoproj.github.io/argo-helm
helm install argo/argo-rollouts --name-template argo-rollouts --create-namespace -n argo-rollouts --set dashboard.enabled=true --version 2.32.5 --wait
helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm install prometheus-community/kube-prometheus-stack --name-template prometheus --create-namespace -n prometheus --version 54.2.2 --wait
helm install sample-app/helm-charts/argo-rollouts --name-template sample-app --create-namespace -n sample-app --set prometheus.enabled=true --wait
kubectl argo rollouts dashboard -n argo-rollouts &
kubectl argo rollouts set image sample-app sample-app=ghcr.io/jhandguy/canary-deployment/sample-app:latest -n sample-app
kubectl argo rollouts promote sample-app -n sample-app
```
## Smoke Testing
### Weighted canary
```shell
curl localhost/success -H "Host: sample.app" -v
curl localhost/error -H "Host: sample.app" -v
```
### Always canary
```shell
curl localhost/success -H "Host: sample.app" -H "X-Canary: always" -v
curl localhost/error -H "Host: sample.app" -H "X-Canary: always" -v
```
### Never canary
```shell
curl localhost/success -H "Host: sample.app" -H "X-Canary: never" -v
curl localhost/error -H "Host: sample.app" -H "X-Canary: never" -v
```
## Load Testing
```shell
k6 run k6/script.js
```
## Uninstalling
```shell
kind delete cluster
```
