Kube toolkit

Welcome! This project provides:

• Curated Guides: Step-by-step instructions for installing popular applications using their official Helm charts in a Kubernetes cluster.
• Custom Helm Charts: A collection of Helm charts that were created for deploying unique workloads on Kubernetes.

Whether you're deploying custom solutions or setting up well-known applications like NGINX or Prometheus, this repository aims to simplify your Kubernetes journey with tested configurations and clear documentation.

Get started with the documentation.

Feel free to contribute!

Usage

From Helm CLI

# checks helm is installed
helm version

# if not already done, adds devpro repository in helm
helm repo add devpro https://devpro.github.io/helm-charts

# refreshes helm repository informations
helm repo update

# searches for a specific package from the command line
helm search repo -l <package_name>

# installs a package
helm install <package_name>

From ArgoCD

• Create a git repository to store Kubernetes definition files (GitOps approach)

# wordpress/Chart.yaml
apiVersion: v2
name: wordpress
description: Helm chart for installing WordPress
type: application
version: 0.1.0
appVersion: 1.0.0
dependencies:
  - name: wordpress
    version: 0.1.1
    repository: https://devpro.github.io/helm-charts

• Create a new application in ArgoCD to reference the git repository with the path to the folder

From Fleet

• Create a git repository to store Kubernetes definition files (GitOps approach)

# wordpress/fleet.yaml
defaultNamespace: sample-apps
helm:
  repo: https://devpro.github.io/helm-charts
  chart: wordpress
  version: 0.1.1
  releaseName: wordpress

• Create a GitRepo to reference the git repository with the path to the folder

• In your cluster
  • Go to "Apps" > "Repositories", click on "Create" and enter https://devpro.github.io/helm-charts as "Index URL", then click on "Create"
  • Go to "Apps" > "Charts", look at the available applications (charts) and install the one(s) you want

Cluster setup logic

• Create a Kubernetes Cluster and get CLI access (download kubectl configuration)
• Install & configure kube add-ons
  • Install certificate issuer (cert-manager)
  • Create storage class
  • Create Ingress Controller (NGINX or HAProxy)
  • Create load balancer
  • Install secret management (Sealed Secrets)
  • Deploy GitOps tool (ArgoCD or Fleet)
• Setup Security (NeuVector)
• Install Observability (OpenTelemetry, Prometheus, Grafana)
• Setup Continuous Deployment
  • Configure GitOps repositories and deploy backing services and applications
