Kubernetes Monitoring and Logging

This skill manages monitoring and logging in Kubernetes environments, enabling the setup of Prometheus and Grafana for observability.

When to Use

Use this skill when:

• Setting up a new Kubernetes cluster and needing to implement monitoring.
• Reviewing or enhancing existing monitoring and logging strategies.
• Ensuring compliance with best practices for observability in Kubernetes.

Core Workflow

1. Setup Prometheus
   a. Deploy Prometheus using Helm charts or YAML manifests.
   b. Configure Prometheus to scrape metrics from your desired endpoints.

2. Deploy Grafana
   a. Install Grafana using Helm charts or YAML manifests.
   b. Configure data sources to connect Grafana to Prometheus.
   c. Create dashboards to visualize your metrics.

3. Implement Logging
   a. Choose a logging solution (e.g., ELK Stack or Fluentd).
   b. Configure your logging solution to capture logs from all relevant Kubernetes pods.

Implementation Patterns

Pattern 1: Deploying Prometheus

apiVersion: v1
kind: Service
metadata:
  name: prometheus
  labels:
    app: prometheus
spec:
  type: ClusterIP
  ports:
    - name: web
      port: 9090
  selector:
    app: prometheus
---

apiVersion: apps/v1
kind: Deployment
metadata:
  name: prometheus
spec:
  replicas: 1
  selector:
    matchLabels:
      app: prometheus
  template:
    metadata:
      labels:
        app: prometheus
    spec:
      containers:
        - name: prometheus
          image: prom/prometheus:latest
          args:
            - '--config.file=/etc/prometheus/prometheus.yml'
          ports:
            - containerPort: 9090
          volumeMounts:
            - name: prometheus-config
              mountPath: /etc/prometheus
      volumes:
        - name: prometheus-config
          configMap:
            name: prometheus-config 

Pattern 2: Deploying Grafana

apiVersion: v1
kind: Service
metadata:
  name: grafana
spec:
  type: NodePort
  ports:
    - port: 3000
      targetPort: 3000
  selector:
    app: grafana
---

apiVersion: apps/v1
kind: Deployment
metadata:
  name: grafana
spec:
  replicas: 1
  selector:
    matchLabels:
      app: grafana
  template:
    metadata:
      labels:
        app: grafana
    spec:
      containers:
        - name: grafana
          image: grafana/grafana:latest
          ports:
            - containerPort: 3000
          env:
            - name: GF_SECURITY_ADMIN_PASSWORD
              value: admin

Constraints

MUST DO

• Ensure that Prometheus is configured to scrape all necessary Kubernetes metrics.
• Set up Grafana dashboards for critical metrics that need monitoring regularly.

MUST NOT DO

• Do not expose Prometheus or Grafana services directly to the public internet without authentication.
• Avoid using default credentials for Grafana and Prometheus accounts.
