Monitoring, CI/CD, and Disaster Recovery

1.1 Overview

This section describes the configuration and implementation of continuous integration/continuous deployment (CI/CD), system monitoring, and disaster recovery strategies for CapsureLabs. These processes ensure platform stability, allow for rapid iteration, and provide resilience against unexpected failures.

1.2 CI/CD Pipeline Setup

1.2.1 Pipeline Overview

Build Stage

Compile code, build Docker images, and store in a registry.

Test Stage

Deploy Stage

1.2.2 GitLab CI Pipeline Configuration

stages:
  - build
  - test
  - deploy

variables:
  DOCKER_IMAGE: registry.gitlab.com/capsurelabs/app

build:
  stage: build
  script:
    - docker build -t $DOCKER_IMAGE .
    - docker push $DOCKER_IMAGE

test:
  stage: test
  script:
    - docker run $DOCKER_IMAGE npm test

deploy:
  stage: deploy
  environment: production
  script:
    - kubectl apply -f kubernetes/deployment.yaml
    - kubectl apply -f kubernetes/service.yaml
  only:
    - main

1.3 Monitoring System Setup with Prometheus and Grafana

1.3.1 Prometheus Configuration

apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
  name: app-monitor
  labels:
    app: capsurelabs
spec:
  selector:
    matchLabels:
      app: capsurelabs
  endpoints:
    - port: http
      interval: 15s
      path: /metrics

1.3.2 Grafana Configuration

Dashboard Setup

Use predefined Prometheus queries in Grafana to monitor CPU usage, memory, network traffic, and error rates.

Alerting

# CPU Usage
sum(rate(container_cpu_usage_seconds_total{namespace="capsurelabs"}[5m])) by (pod)

1.4 Disaster Recovery Strategy

1.4.1 Backup Management

velero backup create capsurelabs-backup --include-namespaces=capsurelabs

1.4.2 Data Redundancy and Storage

Database Replication

Use database replication (e.g., PostgreSQL replication) to ensure copies of data are maintained across multiple nodes.

Persistent Storage Snapshots

1.4.3 Failover Mechanisms

readinessProbe:
  httpGet:
    path: /health
    port: 80
  initialDelaySeconds: 5
  periodSeconds: 10
livenessProbe:
  httpGet:
    path: /health
    port: 80
  initialDelaySeconds: 5
  periodSeconds: 10
