Verify Keys Added to SSH Agent

ssh-add -l

Copy Key to Remote Server

ssh-copy-id user@remote.server.location

Copy Server Key to Host

Prometheus monitoring stack on Ubuntu 22.04.2 and Micro Kubernetes Cluster (microk8s)

Posted on by

1) Install Ubuntu 22.04.2 desktop

Install guest agent:

sudo apt-get install qemu-guest-agent
sudo systemctl start qemu-guest-agent

Optional – Add the curret user to the sudo group:

sudo usermod -aG sudo $USER

2) Configure RDP and VNC

fix the lock problem:

3) Install docker

sudo apt install docker.io

add the current user to docker group:

sudo usermod -aG docker $USER

4) Check docker version

docker --version

5) Create a Micro Kubernetes Cluster (microk8s)

See here: https://microk8s.io/docs/getting-started

sudo snap install microk8s --classic --channel=1.27

MicroK8s creates a group to enable seamless usage of commands which require admin privilege. To add your current user to the group and gain access to the .kube caching directory, run the following two commands:

sudo usermod -a -G microk8s $USER
sudo chown -f -R $USER ~/.kube

See the node:

microk8s kubectl get nodes

See the running services:

microk8s kubectl get services

Create an alias:

alias kubectl='microk8s kubectl'

Deploy an app:

microk8s kubectl create deployment nginx --image=nginx
microk8s kubectl get pods

Starting and Stopping MicroK8s:

microk8s stop
microk8s start

export the cluster configuration

kubectl config view --raw > ~/.kube/config

6) Alternatively – install minikube

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube_latest_amd64.deb
sudo dpkg -i minikube_latest_amd64.deb

start your cluster:

minikube start

Install kubectl:

snap install kubectl --classic
kubectl version --client

7) Install helm

$ curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3
$ chmod 700 get_helm.sh
$ ./get_helm.sh

or using snap:

sudo snap install helm --classic

8) Deploy Prometheus monitoring stack to Kubernetes with a single Helm Chart

See: https://dev.to/kaitoii11/deploy-prometheus-monitoring-stack-to-kubernetes-with-a-single-helm-chart-2fbd

helm repo add prometheus-community https://prometheus-community.github.io/helm-charts

helm repo update

kubectl create ns prom

helm search repo prometheus-community

helm install prometheus prometheus-community/kube-prometheus-stack -n prom

helm install ksm prometheus-community/kube-state-metrics -n prom # install the kube-state-metrics

kubectl --namespace prom get pods

Check configmaps and secrets:

kubectl --namespace prom get configmap
kubectl --namespace prom get secret

Look inside a secret file:

kubectl --namespace prom get secret

Check CRDs

kubectl get crd

9) Access Prometheus Dashboard

$ kubectl port-forward -n prom service/prometheus-kube-prometheus-prometheus 9090

10) Access Grafana Dashboard

$ kubectl port-forward -n prom deployment/prometheus-grafana 3000

default user/password is admin/prom-operator

11) Uninstall Prometheus stack

$ helm uninstall ksm -n prom
$ helm uninstall prom -n prom

12) Install and use K8S Lens to explore what was deployed in the kluster:
