在 AWS TNB 中更新网络实例

亚马逊 EKS 集群版本

您可以将 Amazon EKS 集群控制平面version参数的值更新到下一个次要版本。您无法降级版本。工作节点未更新。

EKSCluster:
      type: tosca.nodes.AWS.Compute.EKS
      properties:
        version: "1.28"

EKSCluster:
      type: tosca.nodes.AWS.Compute.EKS
      properties:
        version: "1.29"

缩放属性

您可以更新EKSManagedNode和 EKSSelfManagedNode TOSCA 节点的缩放属性。

EKSNodeGroup01:
    ...
    scaling:
        properties:
            desired_size: 1
            min_size: 1
            max_size: 1

EKSNodeGroup01:
    ...
    scaling:
        properties:
            desired_size: 2
            min_size: 0
            max_size: 2

亚马逊 EBS CSI 插件属性

您可以在亚马逊 EKS 集群上启用或禁用 Amazon EBS CSI 插件。您也可以更改插件版本。

EKSCluster:
  capabilities:
   ...
    ebs_csi:
      properties:
        enabled: false

EKSCluster:
  capabilities:
   ...
    ebs_csi:
      properties:
        enabled: true
        version: "v1.30.0-eksbuild.1"

VNF

您可以在 NSD VNFs 中引用，然后使用 VNFDeployment TOSCA 节点将它们部署到在 NSD 中创建的集群中。作为更新的一部分，您将能够向网络添加、更新和删除 VNFs 。

        vnfs:
          - vnf1.SampleVNF1
          - vnf3.SampleVNF3

挂钩

要在创建网络函数之前和之后运行生命周期操作，请将pre_create和post_create挂钩添加到VNFDeployment节点。

在此示例中，PreCreateHook挂钩将在实例化之前vnf3.SampleVNF3运行，PostCreateHook挂钩将在实例化之后vnf3.SampleVNF3运行。

SampleVNF1HelmDeploy:
  type: tosca.nodes.AWS.Deployment.VNFDeployment
  requirements:
    cluster: EKSCluster
    vnfs:
      - vnf1.SampleVNF1 // No change to this function, as the namespace and uuid remain the same
      - vnf3.SampleVNF3 // New VNF as the namespace, vnf3, was not previously present
  interfaces:
    Hook:
      post_create: PostCreateHook
      pre_create: PreCreateHook

挂钩

要在更新网络函数之前和之后运行生命周期操作，可以将pre_update挂钩和post_update挂钩添加到VNFDeployment节点。

在此示例中，PreUpdateHook将在更新之前运行vnf1.SampleVNF1，并在PostUpdateHook更新到命名空间 vnf1 所指示uuid的vnf包之后vnf1.SampleVNF1运行。

vnfds:
  - descriptor_id: "43c012fa-2616-41a8-a833-0dfd4c5a049e"
