K8sMonitor Helm Chart

This Helm chart provides a standardized way to deploy the K8sMonitor python web application on a Kubernetes cluster.

Prerequisites

A running Kubernetes cluster.
Helm installed on your local machine or CI/CD runner.
Access to a container registry where the python-web-app image is stored (if using a custom image).

Getting Started

1. Prepare the Configuration

The default configuration can be found in values.yaml. You can override any value here before installing or pass them via --set or -f <file>.

Example of modifying ingress annotations:

ingress:
  annotations:
    cert-manager.io/cluster-issuer: "letsencrypt-prod"

2. Install the Chart

To install the chart using the default values:

helm install k8smonitor ./helm-chart

To install with a custom values file:

helm install k8smonitor ./helm-chart -f custom-values.yaml

3. Upgrade the Chart

To update your installation with newer configuration or version:

helm upgrade k8smonitor ./helm-chart

Configuration Options

Value	Description	Default
`replicaCount`	Number of desired pods	2
`image.repository`	The Docker image to pull	python-web-app
`service.port`	The port the service listens on	80
`ingress.enabled`	Enable or disable Ingress	true
`persistence.size`	Size of the PersistentVolumeClaim	1Gi

Verification

Once installed, you can check the status of your deployment:

# List all pods for the app
kubectl get pods -l app=k8smonitor

# Check the service
kubectl get svc k8smonitor

# Check the ingress
kubectl get ingress k8smonitor

Troubleshooting

If the pod is not running, check the logs:

kubectl logs -l app=k8smonitor

Check for events in the namespace:

kubectl get events --sort-by=.metadata.creationTimestamp
