网络ACL组、网络ACL策略、网络ACL规则之间的关系是什么?
三者关系
网络ACL资源分为网络ACL组、网络ACL策略和网络ACL规则。
三者的关系是:
- 一个网络ACL策略可以绑定多个网络ACL规则,
- 一个网络ACL组可以绑定两个网络ACL策略,分别是入方向网络ACL策略和出方向网络ACL策略,
- 网络ACL策略需要绑定到网络ACL组使用。
登录网络控制台,查看网络ACL的基本信息,可以看到网络ACL组的名称和ID。
在入方向规则或出方向规则界面,可以添加、修改、删除网络ACL规则,这些规则均绑定在同一个入方向策略或出方向策略中。
示例
举例描述创建网络ACL资源的过程,理解三者之间的关系。
- 创建网络ACL规则
POST /v2.0/fwaas/firewall_rules
请求体
{ "firewall_rule": { "name": "fw-rule-ingress-1", "description": "create a ingress firewall rule ", "protocol": "TCP", "action": "ALLOW", "ip_version": 4, "destination_ip_address": "192.168.22.0/24", "source_ip_address": "0.0.0.0/0", "enabled": true } }
响应体,获取到firewall_rule_id:84d10f4a-9f8b-41b8-bdfa-5a0f18736f12

- 创建网络ACL组
POST /v2.0/fwaas/firewall_groups
请求体,绑定入方向网络ACL策略

响应体,获取到firewall_group_id:102493e8-fc6d-4f0d-b57f-55c5be86f5c0
{ "firewall_group": { "id": "102493e8-fc6d-4f0d-b57f-55c5be86f5c0", "name": "fw-group-example", "project_id": "5f6387106c2048b589b369d96c2f23a2", "tenant_id": "5f6387106c2048b589b369d96c2f23a2", "admin_state_up": true, "egress_firewall_policy_id": null, "ingress_firewall_policy_id": "da037721-b895-4e07-bbcc-f5f6ac2759fb", "description": "create a firewall group", "created_at": "2023-03-09T08:54:40", "updated_at": "2023-03-09T08:54:40", "status": "INACTIVE", "ports": [], "public": false } }
登录网络控制台,可以查看到创建的网络ACL资源。
