Deploy PulseNode Agent on Kubernetes

Deploy PulseNode into a Kubernetes cluster in the same namespace as Pulse using the Manager Server deploy addons API, then configure hostname settings via deployment environment variables.

This is supported from Pulse 4.1.0 onwards.

Prerequisites

Access to the Kubernetes cluster
kubectl configured for the target cluster
Pulse Manager Ingress API endpoint

Step 1: Download and Extract the RBAC Package

Download the k8s_tar package and extract it.

Ensure the extracted contents include the file:

Bash
    
 
pulsenode_rbac.yaml
Copy

Step 2: Update the Namespace

Replace the DEFAULT_NAMESPACE value in the YAML file:

Bash
    
 
sed -i -e "s/DEFAULT_NAMESPACE/<pulse-namespace>/g" *.yaml
Copy

Step 3: Apply the RBAC Configuration

Bash
    
 
kubectl apply -f pulsenode_rbac.yaml
Copy

Step 4: Deploy PulseNode to the Pulse Cluster

Run the following command to deploy PulseNode:

Bash
    
 
curl --request PUT \  --url http://<Ingress API for the manager Server>/api/v1/mserver/deploy/pulsenode/<clustername> \  --header 'Authorization: Basic <base64-encoded-credentials>' \  --header 'Content-Type: application/json' \  --data '{    "extra_hosts": {      "<IP_address 1>": "FQDN 1",      "<IP_address 2>": "FQDN 2",      "<IP_address 3>": "FQDN 3"    }  }'
Copy

Step 5: Remove PulseNode from the Pulse Cluster

Remove PulseNode Deployment

Bash
    
 
curl --request PUT \  --url http://<Ingress API for the manager Server>/api/v1/mserver/remove/pulsenode/<clustername> \  --header 'Authorization: Basic <base64-encoded-credentials>'
Copy

Delete the RBAC Configuration

Bash
    
 
kubectl delete -f pulsenode_rbac.yaml
Copy
