以编程方式控制您的负载均衡器

通过 API 以简单、程序化的方式管理负载均衡器

Create Load Balancer

curl -X POST -H "Content-Type: application/json" \
  -H "Authorization: Bearer $TOKEN" \
  -d '{
    "name": "lb-name",
    "region": "nyc3",
    "droplet_ids": [<DROPLET_ID1>],
    "forwarding_rules": [{
      "entry_protocol": "http",
      "entry_port": 80,
      "target_protocol": "http",
      "target_port": 80
    }]
  }' \
  "https://api.digitalocean.com/v2/load_balancers"

Add another droplet

curl -X POST -H "Content-Type: application/json" \
  -H "Authorization: Bearer $TOKEN" \
  -d '{
    "droplet_ids": [<DROPLET_ID2>]
  }' \
  "https://api.digitalocean.com/v2/load_balancers/<LB_UUID>/droplets"

使用负载均衡器创建高可用设置可以执行多种操作，包括通过 API 创建新的负载均衡器，并向其添加 Droplets（Go 和 Ruby 封装器即将推出）。支持 OAuth。
