KubeEye is a cloud-native cluster inspection tool specifically designed for Kubernetes, capable of identifying issues and risks within the Kubernetes cluster based on custom rules.

QuickStart

Installation

Download the installation package from Releases, which includes Helm chart, demo rules, and images for offline installation.

VERSION=v1.0.0

wget https://github.com/kubesphere/kubeeye/releases/download/${VERSION}/kubeeye-offline-${VERSION}.tar.gz

tar -zxvf kubeeye-offline-${VERSION}.tar.gz

cd kubeeye-offline-${VERSION}

# offline installation, please import the images in the 'images' folder into the local container repository yourself and modify the images repo in `chart/kubeeye/values.yaml`.

helm upgrade --install kubeeye chart/kubeeye -n kubeeye-system --create-namespace

Usage

Import Inspect Rules

The rule directory in the installation package provides demo rules, which can be customized according to specific needs.

Notice： Prometheus rules need to have the endpoint of Prometheus set in advance.

kubectl apply -f rule

Create Inspect Plan

Configure inspection plans on demand.

cat > plan.yaml << EOF
apiVersion: kubeeye.kubesphere.io/v1alpha2
kind: InspectPlan
metadata:
  name: inspectplan
spec:
  # The planned time for executing inspections only supports cron expressions. For example, '*/30 * * * ?' means that the inspection will be performed every 30 minutes.'
  # If only a single inspection is required, then remove this parameter.
  schedule: "*/30 * * * ?"
  # The maximum number of retained inspection results, if not filled in, will retain all.
  maxTasks: 10 
  # Should the inspection plan be paused, applicable only to periodic inspections, true or false (default is false).
  suspend: false
  # Inspection timeout, default 10 minutes.
  timeout: 10m
  # Inspection rule list, used to associate corresponding inspection rules, please fill in the inspectRule name.
  # Execute `kubectl get inspectrule` to view the inspection rules in the cluster.
  ruleNames:
    - name: inspect-rule-filter-file
    - name: inspect-rule-node-info
    - name: inspect-rule-node
