### Kubernetes dashboard
#### View your running workload
> We provide a web interface to visualise your workloads you have access to, you can connect to https://console.k8s-dev.pasteur.fr and follow the login process. On the left panel, you will find a drop down list and select your namespace. You will be able to view your Deployements, Pods, Services and so on.
#### Increase the number of replicas
If you want to increase the number of replicas of your web application, you can go in the Deployement section and select the 3 dots on the `polls` line; select `Scale`. You can increase or decrease the number of replicas. Kubernetes will automaticaly add or remove Pods.
#### What happen if I kill a Pod ?
You can try to `Delete` the polls `Pod` using the 3 dots icon and see that Kubernetes will automaticaly restart a new one.
### Grafana : Metrics and Logs
You can log on https://grafana.k8s-dev.pasteur.fr/ and browse the various dashboard available.

Integrate Kubernetes at the beginning of your project, you'll waste less time.
