minikube start --driver=virtualbox
minikube status
minikube dashboard
kubectl config use-context minikube
eval $(minikube docker-env) # so the image can be created in space viewable from the minikube
cd in/the/project
docker build . -t teo/scalable-app
kubectl apply -f nginx_deployment.yaml
kubectl apply -f nginx_service.yaml
kubectl apply -f nginx_configMap.yaml
kubectl apply -f php_deployment.yaml
kubectl apply -f php_service.yaml
minikube service nginx # auto load
minikube service nginx --url # for manual copy
Because we are using busybox image in initContainer lifecycle event, this will not copy code from our image to volume because php container or pod is not yet created. So we might get forbidden or NOT FOUND error when we open our nginx service in browser, so we have to copy code manually to the /code/scale-app/ directory
kubectl get pods
# login into the pod
kubectl exec -it scalable-app-<one random pod name> -- /bin/bash
# copy the app in the correct destination
cp -r /var/www/. /code/scalable-app
# fix some permissions
chown -R $USER:www-data storage/
chown -R $USER:www-data bootstrap/cache/
chmod -R 775 storage/
chmod -R 775 bootstrap/cache/
minikube addons enable ingress
kubectl apply -f ingress.yaml
kubectl describe ingress
Now the app can be found in the given
minikube addons enable metrics-server
kubectl apply -f autoscaling.yaml
we can also do kubectl apply -f ./ to set all the .yaml files simultaneously
kubectl delete deployment scalable-app
kubectl delete service scalable-app
kubectl delete deployment nginx
kubectl delete service nginx
kubectl delete configmap nginx-config
kubectl delete ingress scalable-app
Using the SIEGE 4.0.4
