Light Version

The light version of the Low-Ops platform allows you to run Low-Ops on a single Linux machine, making it ideal for testing purposes.

Prerequisites

Required Packages

Ensure the following binaries are installed on the machine with access to the Kubernetes API before starting:

  • kubectl - Version v1.27
  • helm - Version v3.9
  • kind - Version v1.27

Kubernetes Cluster

The Low-Ops platform requires a Kubernetes cluster. Currently supported Kubernetes versions are:

  • v1.27
  • v1.28
  • v1.29

System Resources

To run the platform, the system should have at least 16 GB of RAM and an 8-core CPU.

Platform Foundation

This setup requires a single Linux server with internet access and Docker installed.

Platform Installation

Step 1: Install Kubernetes Cluster

Create a kind-config.yaml configuration file with the following content:

kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
- role: control-plane
- role: worker
- role: worker
- role: worker
networking:
  apiServerPort: 6443
  apiServerAddress: 0.0.0.0

Create the Kubernetes cluster on the Linux server. Replace dev with your company or project name:

kind create cluster --name dev --config ./kind-config.yaml --image "kindest/node:v1.27.3" -v 1

Retrieve the Kubernetes configuration from the created cluster:

kind get kubeconfig --name=dev > ~/.kube/config

Step 2: Install Proxy (Required Only for Light Platform Installation)

Create an haproxy.cfg file with the following content:

global
    log stdout format raw local0 info

defaults
    log global
    retries 2
    option dontlognull
    timeout connect 10000
    timeout server 600000
    timeout client 600000

frontend http_frontend
    bind *:80 
    default_backend http_backend

frontend https_frontend
    bind *:443 
    default_backend https_backend

backend https_backend
    server nginx-ingress 172.19.255.200:443 check send-proxy

backend http_backend
    server nginx-ingress 172.19.255.200:80 check send-proxy

Start the HAProxy service using the following command:

docker run -d \
    --restart unless-stopped \
    --name haproxy \
    --network=kind \
    -v $(pwd)/haproxy.cfg:/usr/local/etc/haproxy/haproxy.cfg:ro \
    -p 443:443 \
    -p 80:80 \
    haproxytech/haproxy-alpine:2.4
