Deploying on Kubernetes

Follow the instructions below to deploy the agent on your Kubernetes cluster.

Create a config file as described in the previous section, and name it pulse-agent-config.yml. Then create a secret from it:

# Create a new secret named pulse-agent-config with local file pulse-agent-config.yml as the config.yml
kubectl create secret generic pulse-agent-config --from-file=config.yml=pulse-agent-config.yml

Now create the deployment spec in a separate file called pulse-deployment.yaml.

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: pulse-agent
  name: pulse-agent
spec:
  replicas: 1
  revisionHistoryLimit: 2
  selector:
    matchLabels:
      app: pulse-agent
  template:
    metadata:
      labels:
        app: pulse-agent
    spec:
      automountServiceAccountToken: false
      containers:
        - image: r.bigdataboutique.com/pulse-agent
          imagePullPolicy: Always
          name: pulse-agent
          env:
            - name: PULSE_ENVIRONMENT_NAME
              value: my-environment
            - name: PULSE_AGENT_HEAP_SIZE
              value: 2G
          resources:
            limits:
              cpu: "1"
              memory: 16Gi
            requests:
              cpu: 100m
              memory: 2Gi
          livenessProbe:
            httpGet:
              path: /healthz
              port: 8080
            initialDelaySeconds: 30
            periodSeconds: 10
            timeoutSeconds: 1
          readinessProbe:
            httpGet:
              path: /healthz
              port: 8080
            initialDelaySeconds: 10
            periodSeconds: 10
            timeoutSeconds: 1
          volumeMounts:
            - mountPath: /etc/pulse-agent
              name: config
              readOnly: true
      dnsPolicy: ClusterFirst
      restartPolicy: Always
      volumes:
        - name: config
          secret:
            defaultMode: 420
            secretName: pulse-agent-config

Finally, apply the spec:

kubectl apply -f pulse-deployment.yaml
