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

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:

No Roof Scams

Posted on by

There are many things consumers can do to guard against being the victim of a fraudulent roofing contractor.

  • Look for well-established, licensed, insured and bonded roofing professionals with a federal tax identification number and a permanent address.
  • Ask for a contractor’s license number and confirm with your city or county building department that the license number was issued by them and is current.
  • Check to make sure the contractor is registered to conduct business in Colorado at https://www.sos.state.co.us/biz/BusinessEntityCriteriaExt.do.
  • Ask to see the company’s certificates of insurance. Verify with the insurer the certificate is valid, the contractor is endorsed for roofing work, and the contractor’s coverage for liability and workers’ compensation is current. CONSUMER TIP: Check the number of employees covered by the policy – a low number indicates the contractor will hire temporary help who may or may not have roofing experience.
  • Don’t hire a contractor who knocks on your door following a storm. Most legitimate roofing contractors do not conduct business this way.
  • Contact the Colorado Roofing Association (CRA), which maintains a current list of licensed, properly insured, professional contractors who have committed to abiding by the CRA Code of Ethics, and have passed a nationally recognized exam that addresses roofing work on residential and/or commercial property.
  • Contact the Better Business Bureau to check for complaints filed against any company you are considering hiring.
  • Be sure to get more than one estimate.
  • Require references that specifically include other homes in your area, and check them.
  • Make sure you review and understand all documents sent to your insurance carrier.
  • Never pay a contractor in full or sign a completion certificate until all the work is completed.
  • Don’t be pushed into signing a contract right away. Never sign a contract with blanks or statements like “see insurance estimate, etc.” – fraudulent contractors may enter unacceptable terms later.
  • Always ensure that before you sign a contract it includes all the requirements established in Colorado Senate Bill 38.
    1. Scope of work and materials to be provided.
    2. Cost for same based on damages known at the time the contract is entered into.
    3. Approximate dates of service.
    4. Roofing contractor’s contact information.
    5. Identification of contractor’s surety and liability coverage insurer and their contact information.
    6. Contractor’s policy regarding cancellation of contract and refund of any deposit including a rescission clause allowing the property owner to rescind the contract for roofing services and obtain a full refund of any deposit within 72 hours after entering the contract.
    7. A statement that if the property owner plans to pay for the roofing services through an insurance claim, the contractor cannot pay, waive or rebate the homeowner’s insurance deductible in part or in whole.
    8. A statement that the contractor shall hold in trust any payment from the property owner until the contractor has delivered roofing materials to the jobsite or has performed a majority of the roofing work on the property.
    9. A statement that the property owner may rescind a contract for services, the payment for which will be made from the proceeds of a property insurance claim, within 72 hours after receiving notice from their insurer that the claim is denied in whole or in part.
