安裝 SeeSaw 負載平衡器
本頁列出了 SeeSaw 託管負載平衡器的安裝和設定說明。
Seesaw 是安裝在 VMware Anthos Clusters 環境中(版本 1.6 至 1.10)的預設託管網路負載平衡器。
安裝 SeeSaw 負載平衡器
SeeSaw 負載平衡器與 VMware 上的 Anthos Clusters 完全集成,並作為管理員和使用者叢集設定的一部分執行自動部署。有文字區塊 `cluster.yaml`必須修改設定檔以提供負載平衡器信息,然後在叢集部署之前還有一個額外的步驟,使用內建的 `gkectl`工具。

SeeSaw 負載平衡器可以 HA 或非 HA 模式部署。為了進行此驗證,SeeSaw 負載平衡器以非 HA 模式部署,這是預設值。出於生產目的, NetApp建議在 HA 配置中部署 SeeSaw,以實現容錯和可靠性。 |
與 Anthos 集成
每個設定檔中都有一個部分,分別用於管理員叢集和您選擇部署的每個使用者集群,以配置負載平衡器,以便由 Anthos On-Prem 管理。
以下文字是 GKE-Admin 叢集分區配置的範例。需要取消註解和修改的值以粗體顯示如下:
loadBalancer:
# (Required) The VIPs to use for load balancing
vips:
# Used to connect to the Kubernetes API
controlPlaneVIP: "10.61.181.230"
# # (Optional) Used for admin cluster addons (needed for multi cluster features). Must
# # be the same across clusters
# # addonsVIP: ""
# (Required) Which load balancer to use "F5BigIP" "Seesaw" or "ManualLB". Uncomment
# the corresponding field below to provide the detailed spec
kind: Seesaw
# # (Required when using "ManualLB" kind) Specify pre-defined nodeports
# manualLB:
# # NodePort for ingress service's http (only needed for user cluster)
# ingressHTTPNodePort: 0
# # NodePort for ingress service's https (only needed for user cluster)
# ingressHTTPSNodePort: 0
# # NodePort for control plane service
# controlPlaneNodePort: 30968
# # NodePort for addon service (only needed for admin cluster)
# addonsNodePort: 31405
# # (Required when using "F5BigIP" kind) Specify the already-existing partition and
# # credentials
# f5BigIP:
# address:
# credentials:
# username:
# password:
# partition:
# # # (Optional) Specify a pool name if using SNAT
# # snatPoolName: ""
# (Required when using "Seesaw" kind) Specify the Seesaw configs
seesaw:
# (Required) The absolute or relative path to the yaml file to use for IP allocation
# for LB VMs. Must contain one or two IPs.
ipBlockFilePath: "admin-seesaw-block.yaml"
# (Required) The Virtual Router IDentifier of VRRP for the Seesaw group. Must
# be between 1-255 and unique in a VLAN.
vrid: 100
# (Required) The IP announced by the master of Seesaw group
masterIP: "10.61.181.236"
# (Required) The number CPUs per machine
cpus: 1
# (Required) Memory size in MB per machine
memoryMB: 2048
# (Optional) Network that the LB interface of Seesaw runs in (default: cluster
# network)
vCenter:
# vSphere network name
networkName: VM_Network
# (Optional) Run two LB VMs to achieve high availability (default: false)
enableHA: false
SeeSaw 負載平衡器還具有單獨的靜態 `seesaw-block.yaml`您必須為每個集群部署提供該檔案。該文件必須位於與 `cluster.yaml`部署文件,或必須在上面的部分指定完整路徑。
樣本 `admin-seesaw-block.yaml`文件類似以下腳本:
blocks:
- netmask: "255.255.255.0"
gateway: "10.63.172.1"
ips:
- ip: "10.63.172.152"
hostname: "admin-seesaw-vm"

該文件提供了負載平衡器向底層叢集提供的網路的網關和網路掩碼,以及為運行負載平衡器而部署的虛擬機器的管理 IP 和主機名稱。 |
