Preparing to install on Alibaba Cloud

Preparing to install on Alibaba Cloud

Alibaba Cloud on OKD is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information about the support scope of Red Hat Technology Preview features, see https://access.redhat.com/support/offerings/techpreview/.

Prerequisites

You reviewed details about the OKD installation and update processes.
You read the documentation on selecting a cluster installation method and preparing it for users.

Requirements for installing OKD on Alibaba Cloud

Before installing OKD on Alibaba Cloud, you must configure and register your domain, create a Resource Access Management (RAM) user for the installation, and review the supported Alibaba Cloud data center regions and zones for the installation.

Registering and Configuring Alibaba Cloud Domain

To install OKD, the Alibaba Cloud account you use must have a dedicated public hosted zone in your account. This zone must be authoritative for the domain. This service provides cluster DNS resolution and name lookup for external connections to the cluster.

Procedure

Identify your domain, or subdomain, and registrar. You can transfer an existing domain and registrar or obtain a new one through Alibaba Cloud or another source.

If you purchase a new domain through Alibaba Cloud, it takes time for the relevant DNS changes to propagate. For more information about purchasing domains through Alibaba Cloud, see Alibaba Cloud domains.

If you are using an existing domain and registrar, migrate its DNS to Alibaba Cloud. See Domain name transfer in the Alibaba Cloud documentation.
Configure DNS for your domain. This includes:
- Registering a generic domain name.
- Completing real-name verification for your domain name.
- Applying for an Internet Content Provider (ICP) filing.
- Enabling domain name resolution.
  
  Use an appropriate root domain, such as openshiftcorp.com, or subdomain, such as clusters.openshiftcorp.com.
If you are using a subdomain, follow the procedures of your company to add its delegation records to the parent domain.

Supported Alibaba regions

You can deploy an OKD cluster to the regions listed in the Alibaba Regions and zones documentation.
