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](https://github.com/kubesphere/kubeeye/releases), which includes Helm chart, demo rules, and images for offline installation.



```shell

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.



```shell

kubectl apply -f rule

```



#### Create Inspect Plan



Configure inspection plans on demand.

```shell

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

    - name: inspect-rule-sbnormalpodstatus 

    - name: inspect-rule-deployment

    - name: inspect-rule-sysctl

    - name: inspect-rule-prometheus

    - name: inspect-rule-filechange

    - name: inspect-rule-systemd

  # nodeName: master

  # nodeSelector:

  #   node-role.kubernetes.io/master: ""        

  # Multi-cluster inspection (currently only supports multi-cluster inspection in KubeSphere)

  # clusterName: 

  # - name: host

EOF



kubectl apply -f plan.yaml

```



#### Obtaining Inspection Reports

##### Check Inspection Results

```shell

# View the name of the inspection result for inspection report download.

kubectl get inspectresult

```

###### Command

```shell

## Get the address and port of kubeeye-apiserver service.

kubectl get svc -n kubeeye-system kubeeye-apiserver -o custom-columns=CLUSTER-IP:.spec.clusterIP,PORT:.spec.ports[*].port



## Download the inspection report, and please replace <> with the actual information obtained from the environment.

curl http://:9090/kapis/kubeeye.kubesphere.io/v1alpha2/inspectresults/\?type\=html -o inspectReport.html



## After downloading, you can use a browser to open the HTML file for viewing.

```

###### Web Console

```shell

## Create a nodePort type svc for kubeeye-apiserver.

kubectl -n kubeeye-system expose deploy kubeeye-apiserver --port=9090 --type=NodePort --name=ke-apiserver-node-port



## Enter the inspection report URL in the browser to view, and remember to replace <> with the actual information obtained from the environment.
