Red Hat Training

A Red Hat training course is available for OpenShift Container Platform

25.2. 为 vSphere 配置 OpenShift Container Platform

您可以通过两种方式为 vSphere 配置 OpenShift Container Platform：

25.2.1. 选项 1：使用 Ansible 为 vSphere 配置 OpenShift Container Platform

您可以通过修改 Ansible 清单文件，为 VMware vSphere(VCP)配置 OpenShift Container Platform。这些更改可在安装后或现有集群进行。

流程

  1. 将以下内容添加到 Ansible 清单文件中： 

    [OSEv3:vars]
openshift_cloudprovider_kind=vsphere
openshift_cloudprovider_vsphere_username=administrator@vsphere.local 1
openshift_cloudprovider_vsphere_password=<password>
openshift_cloudprovider_vsphere_host=10.x.y.32 2
openshift_cloudprovider_vsphere_datacenter=<Datacenter> 3
openshift_cloudprovider_vsphere_datastore=<Datastore> 4
    1
    在 vSphere 中创建和附加磁盘的适当权限的用户名。
    2
    vCenter 服务器地址。
    3
    OpenShift Container Platform 虚拟机所在的 vCenter Datacenter 名称。
    4
    用于创建 VMDK 的数据存储。

  2. 运行 deploy_cluster.yml playbook。 

    $ ansible-playbook -i <inventory_file> \
  playbooks/deploy_cluster.yml

使用 Ansible 安装也会创建并配置以下文件以适合您的 vSphere 环境：

  • /etc/origin/cloudprovider/vsphere.conf
  • /etc/origin/master/master-config.yaml
  • /etc/origin/node/node-config.yaml

作为参考，显示完整清单，如下所示：

OpenShift Container Platform 需要 openshift_cloudprovider_vsphere_ 值，以便能够在持久性卷的数据存储上创建 vSphere 资源。 

$ cat /etc/ansible/hosts

如果您使用需要身份验证的容器 registry，如默认容器镜像 registry，请指定该帐户的凭证。请参阅访问并配置 Red Hat Registry。
注意

红帽不正式支持部署 vSphere 虚拟机环境，但可以配置它。
