Monitoring in Kubernetes with Prometheus and Grafana

Monitoring is an essential part of the overall CI/CD picture. To deploy frequently, you need to be able to have confidence that if a deployment breaks something, you will be able to identify the problem and respond quickly to minimize the impact on users. In this activity, you will learn to install and configure Prometheus and Grafana in a Kubernetes cluster, and you will set up some basic Grafana dashboards to give you insight into the performance of the cluster and the applications running in it.

Challenge

Install Prometheus in the Kubernetes cluster

To do this, make sure you have cloned the Kubernetes charts repo:

cd ~/
git clone https://github.com/ACloudGuru-Resources/charts

Create a prometheus-values.yml with this content:

```
  alertmanager:
    persistentVolume:
      enabled: false
  server:
    persistentVolume:
      enabled: false
```

Use helm to install Prometheus with prometheus-values.yml:

helm install -f ~/prometheus-values.yml ~/charts/stable/prometheus --name prometheus --namespace prometheus

Challenge

Install Grafana in the Kubernetes cluster
To do this, make sure you have cloned the kubernetes charts repo:
```
cd ~/
git clone https://github.com/ACloudGuru-Resources/charts
```
Create a grafana-values.yml with this content (you will use this password to log in to Grafana):
```
adminPassword: somePassword
```
Use helm to install Grafana with grafana-values.yml:
```
helm install -f ~/grafana-values.yml ~/charts/stable/grafana --name grafana --namespace grafana
```
