Предоставление VPS:

• Использование DigitalOcean API:

  import requests
  def create_droplet(api_token, region, size, image):
   headers = {'Content-Type': 'application/json', 'Authorization': f'Bearer {api_token}'}
   data = {'name': 'my-droplet', 'region': region, 'size': size, 'image': image}
   response = requests.post('https://api.digitalocean.com/v2/droplets', headers=headers, json=data)
   return response.json()
  # Example usage
  api_token = 'your-api-token'
  region = 'nyc1'
  size = 's-1vcpu-1gb'
  image = 'ubuntu-18-04-x64'
  droplet = create_droplet(api_token, region, size, image)

• Использование API AWS EC2:

  import boto3
  def create_ec2_instance(region, image_id, instance_type):
   ec2 = boto3.resource('ec2', region_name=region)
   instance = ec2.create_instances(ImageId=image_id, InstanceType=instance_type, MinCount=1, MaxCount=1)
   return instance[0]
  # Example usage
  region = 'us-west-2'
  image_id = 'ami-0c94855ba95c71c99'
  instance_type = 't2.micro'
  ec2_instance = create_ec2_instance(region, image_id, instance_type)

Развертывание приложений на VPS:

• Использование SSH и Git:

  # Clone the repository
  git clone <repository_url>
  # Navigate to the project directory
  cd <project_directory>
  # Install dependencies (if required)
  npm install
  # Build the project
  npm run build
  # Start the application
  npm start

• Использование Docker:

  # Pull the Docker image
  docker pull <image_name>
  # Run the Docker container
  docker run -d -p <host_port>:<container_port> <image_name>

Управление ресурсами VPS:

• Мониторинг с помощью Prometheus и Grafana:

  # Install Prometheus
  wget https://github.com/prometheus/prometheus/releases/download/v2.30.2/prometheus-2.30.2.linux-amd64.tar.gz
  tar -xvf prometheus-2.30.2.linux-amd64.tar.gz
  cd prometheus-2.30.2.linux-amd64/
  ./prometheus --config.file=prometheus.yml
  # Install Grafana
  wget https://dl.grafana.com/oss/release/grafana-8.2.5.linux-amd64.tar.gz
  tar -xvf grafana-8.2.5.linux-amd64.tar.gz
  cd grafana-8.2.5/
  # Start Grafana service
  ./bin/grafana-server --config=./conf/grafana.ini

• Масштабирование с помощью Kubernetes:

  # Install Kubernetes
  curl -LO https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl
  chmod +x kubectl
  sudo mv kubectl /usr/local/bin/
  # Create a deployment
  kubectl create deployment my-app --image=<image_name>
  # Scale the deployment
  kubectl scale deployment my-app --replicas=<replica_count>
