On-Premise Poller for Kubernetes 

On-Premise Poller helps monitor your internal network and resources, like URLs, virtual machines, and network devices, behind a firewall, so you can keep track of the resources behind the virtual private network (VPN). This software requires nearly no maintenance, is firewall-friendly, and can be considered a private monitoring station.

Install On-Premise Poller in Kubernetes

Follow the steps below to install the On-Premise Poller in a Kubernetes environment on a Linux platform.

1. Create a secret for storing the account device key:
   To obtain the device key, log in to your Site24x7 account and go to Admin > Developer > Device Key. 
   Execute the following command in the terminal of Kubernetes environment.
   kubectl create secret generic site24x7-agent --namespace=default --from-literal s247_device_key=<device-key>
2. Download the On-Premise Poller Kubernetes YAML manifest:
   wget https://staticdownloads.site24x7.com/probe/site24x7-poller-statefulset.yaml
3. Update the YAML file with the following information:
   
   

   1. Provide a unique name <cluster-unique-id> that is specific to a Kubernetes cluster, such as using the default namespace UID as a unique identifier. 

      Example: <cluster-unique-id>-s247poller-sts

      For instance, in the above example, replace <cluster-unique-id> with the output from the command:

      kubectl get namespace default -o=jsonpath='{.metadata.uid}'. 

      Alternatively, you can input any other unique name.

   2. Provide a replica value (replicas: 1) for the number of On-Premise Pollers instances required. The default is set to one.
4. For Amazon's Elastic Kubernetes Service (EKS), Microsoft's Azure Kubernetes Service (AKS), and Google's Kubernetes Engine (GKE) distributions, execute this  command to apply configurations defined in a YAML file:
   kubectl apply -f site24x7-poller-statefulset.yaml
   For an OpenShift distribution, execute the below command to apply configurations defined in a YAML file:
   oc apply -f site24x7-poller-statefulset.yaml
