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.

---

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:

pulsenode_rbac.yaml

---

Step 2: Update the Namespace

Replace the DEFAULT_NAMESPACE value in the YAML file:

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

---

Step 3: Apply the RBAC Configuration

kubectl apply -f pulsenode_rbac.yaml

---

Step 4: Deploy PulseNode to the Pulse Cluster

Run the following command to deploy PulseNode:

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"
    }
  }'

---

Step 5: Remove PulseNode from the Pulse Cluster

• Remove PulseNode Deployment

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

• Delete the RBAC Configuration

kubectl delete -f pulsenode_rbac.yaml
