🚀 Инструкция по запуску

⚠️ Перед запуском убедись, что у тебя установлен helm, kubectl и настроен доступ к Kubernetes кластеру (например, minikube или prod-кластер).

---

1. Подготовь ingress-контроллер (если ещё не установлен)

Пример (для Minikube):

minikube addons enable ingress

---

2. Установи Helm-чарт

helm install django-release ./django-microservice-chart

---

3. Проверь, что все поды запущены

kubectl get pods

---

4. Проверь доступ к приложению

Для Minikube:

minikube tunnel
kubectl get ingress

Открой указанный IP (или укажи 127.0.0.1 yourdomain.com в /etc/hosts).

---

5. Обновление чарта

Если ты изменил конфигурации:

helm upgrade django-release ./django-microservice-chart

---

6. Удаление релиза

helm uninstall django-release
