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.
Successfully complete this lab by achieving the following learning objectives:
- Install Prometheus in the Kubernetes cluster.
To do this, make sure you have cloned the Kubernetes charts repo:
cd ~/ git clone https://github.com/kubernetes/charts cd charts git checkout efdcffe0b6973111ec6e5e83136ea74cdbe6527d cd ../
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
- Install Grafana in the Kubernetes cluster.
To do this, make sure you have cloned the kubernetes charts repo:
cd ~/ git clone https://github.com/kubernetes/charts
Create a grafana-values.yml with this content (you will use this password to log in to Grafana):
Use helm to install Grafana with grafana-values.yml:
helm install -f ~/grafana-values.yml ~/charts/stable/grafana --name grafana --namespace grafana
