14.2. 使用 CLI 进行 vSphere 安装后配置

流程

1. 为 vCenter 生成 base64 编码的用户名和密码：

   $ echo -n "<vcenter_username>" | base64 -w0

   Copy to Clipboard Toggle word wrap

   将 <vcenter_username> 替换为您的 vCenter 用户名。

   $ echo -n "<vcenter_password>" | base64 -w0

   Copy to Clipboard Toggle word wrap

   将 <vcenter_password> 替换为您的 vCenter 密码。

2. 备份 vSphere 凭证：

   $ oc get secret vsphere-creds -o yaml -n kube-system > creds_backup.yaml

   Copy to Clipboard Toggle word wrap

3. 编辑 vSphere 凭证：

   $ cp creds_backup.yaml vsphere-creds.yaml

   Copy to Clipboard Toggle word wrap

   $ vi vsphere-creds.yaml

   Copy to Clipboard Toggle word wrap

   apiVersion: v1
   data:
     <vcenter_address>.username: <vcenter_username_encoded>
     <vcenter_address>.password: <vcenter_password_encoded>
   kind: Secret
   metadata:
     annotations:
       cloudcredential.openshift.io/mode: passthrough
     creationTimestamp: "2022-01-25T17:39:50Z"
     name: vsphere-creds
     namespace: kube-system
     resourceVersion: "2437"
     uid: 06971978-e3a5-4741-87f9-2ca3602f2658
   type: Opaque

   Copy to Clipboard Toggle word wrap

   将 <vcenter_address> 替换为 vCenter 地址。将 <vcenter_username_encoded> 替换为 vSphere 用户名的 base64 编码版本。将 <vcenter_password_encoded> 替换为 vSphere 密码的 base64 编码版本。

4. 替换 vSphere 凭证：

   $ oc replace -f vsphere-creds.yaml

   Copy to Clipboard Toggle word wrap

5. 重新部署 kube-controller-manager pod：

   $ oc patch kubecontrollermanager cluster -p='{"spec": {"forceRedeploymentReason": "recovery-'"$( date --rfc-3339=ns )"'"}}' --type=merge

   Copy to Clipboard Toggle word wrap

6. 备份 vSphere 云供应商配置：

   $ oc get cm cloud-provider-config -o yaml -n openshift-config > cloud-provider-config_backup.yaml

   Copy to Clipboard Toggle word wrap

7. 编辑云供应商配置：

   $ cloud-provider-config_backup.yaml cloud-provider-config.yaml

   Copy to Clipboard Toggle word wrap

   $ vi cloud-provider-config.yaml

   Copy to Clipboard Toggle word wrap

   apiVersion: v1
   data:
     config: |
       [Global]
       secret-name = "vsphere-creds"
       secret-namespace = "kube-system"
       insecure-flag = "1"
   
       [Workspace]
       server = "<vcenter_address>"
       datacenter = "<datacenter>"
       default-datastore = "<datastore>"
       folder = "/<datacenter>/vm/<folder>"
   
       [VirtualCenter "<vcenter_address>"]
       datacenters = "<datacenter>"
   kind: ConfigMap
   metadata:
     creationTimestamp: "2022-01-25T17:40:49Z"
     name: cloud-provider-config
     namespace: openshift-config
     resourceVersion: "2070"
     uid: 80bb8618-bf25-442b-b023-b31311918507

   Copy to Clipboard Toggle word wrap

   将 <vcenter_address> 替换为 vCenter 地址。将 <datacenter> 替换为数据中心的名称。将 <datastore> 替换为数据存储的名称。将 <folder> 替换为包含集群虚拟机的文件夹。

8. 应用云供应商配置：

   $ oc apply -f cloud-provider-config.yaml

   Copy to Clipboard Toggle word wrap

9. 使用 uninitialized 污点为集群加污点：

   重要

   如果要安装 OpenShift Container Platform 4.13 或更高版本，请执行以下的第 9 步到第 12 步。

   1. 识别要加污点的节点：

      $ oc get nodes

      Copy to Clipboard Toggle word wrap

   2. 对每个节点运行以下命令：

      $ oc adm taint node <node_name> node.cloudprovider.kubernetes.io/uninitialized=true:NoSchedule

      Copy to Clipboard Toggle word wrap

      将 <node_name> 替换为节点的名称。

   示例

   $ oc get nodes
   NAME                STATUS   ROLES                  AGE   VERSION
   master-0   Ready    control-plane,master   45h   v1.26.3+379cd9f
   master-1   Ready    control-plane,master   45h   v1.26.3+379cd9f
   worker-0   Ready    worker                 45h   v1.26.3+379cd9f
   worker-1   Ready    worker                 45h   v1.26.3+379cd9f
   master-2   Ready    control-plane,master   45h   v1.26.3+379cd9f
   
   $ oc adm taint node master-0 node.cloudprovider.kubernetes.io/uninitialized=true:NoSchedule
   $ oc adm taint node master-1 node.cloudprovider.kubernetes.io/uninitialized=true:NoSchedule
   $ oc adm taint node master-2 node.cloudprovider.kubernetes.io/uninitialized=true:NoSchedule
   $ oc adm taint node worker-0 node.cloudprovider.kubernetes.io/uninitialized=true:NoSchedule
   $ oc adm taint node worker-1 node.cloudprovider.kubernetes.io/uninitialized=true:NoSchedule
