      Note:
      Bill-by-CVM accounts cannot be used to enable public network access for native nodes. For more information, see Account Types. If you use a bill-by-CVM account, you can submit a ticket to upgrade your account.
      This document describes how to bind a node to an elastic IP (EIP) and enable public network access for the node in the TKE console or using YAML.

      Note

      In a node pool with public network access enabled, each time a native node is created, an EIP is automatically created and bound to the node.
      The EIP bound to a node has the same lifecycle as the node.
      When you use native nodes, no fees are charged for EIPs.

      Using the Console to Enable Public Network Access for Native Nodes

      1. Log in to the TKE console and select Cluster in the left sidebar.
      2. On the cluster list page, click the ID of the target cluster to go to the details page.
      3. Choose Node management > Node pool in the left sidebar. On the Node pool list page, click Create node pool.
      4. On the Create node pool page, click Model configuration. On the Model configuration page, select Create EIP, as shown below:
      
      5. Click Create node pool.

      Fields

      Field Name
      Field Value
      Description
      spec.template.spec.providerSpec.value.internetAccessible
      addressType
      EIP: If this field is left empty, a standard EIP is used.
      HighQualityEIP: A BGP IP (dedicated EIP) is used.
      chargeType
      Billing mode:
      TrafficPostpaidByHour: Postpaid by traffic on an hourly basis.
      BandwidthPostpaidByHour: Postpaid by bandwidth on an hourly basis.
      BandwidthPackage: Paid by shared bandwidth package. The EIP must be in the allowlist of the bandwidth package.
      maxBandwidthOut
      Maximum bandwidth in Mbps.
      bandwidthPackageID
      ID of the shared bandwidth package.
      Note
      BGP IPs support only bill-by-IP accounts in the Hong Kong (China) region. You can go to the Virtual Private Cloud (VPC) console to create a shared bandwidth package.
