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
- Versionv1.27
helm
- Versionv3.9
kind
- Versionv1.27
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
