2.9. Installing a cluster on user-provisioned infrastructure in AWS by using CloudFormation templates
In OpenShift Container Platform version 4.5, you can install a cluster on Amazon Web Services (AWS) that uses infrastructure that you provide.
One way to create this infrastructure is to use the provided CloudFormation templates. You can modify the templates to customize your infrastructure or use the information that they contain to create AWS objects according to your company’s policies.
The steps for performing a user-provisioned infrastructure installation are provided as an example only. Installing a cluster with infrastructure you provide requires knowledge of the cloud provider and the installation process of OpenShift Container Platform. Several CloudFormation templates are provided to assist in completing these steps or to help model your own. You are also free to create the required resources through other methods; the templates are just an example.
2.9.1. Prerequisites
- Review details about the OpenShift Container Platform installation and update processes.
Configure an AWS account to host the cluster.
重要If you have an AWS profile stored on your computer, it must not use a temporary session token that you generated while using a multi-factor authentication device. The cluster continues to use your current AWS credentials to create AWS resources for the entire life of the cluster, so you must use key-based, long-lived credentials. To generate appropriate keys, see Managing Access Keys for IAM Users in the AWS documentation. You can supply the keys when you run the installation program.
- Download the AWS CLI and install it on your computer. See Install the AWS CLI Using the Bundled Installer (Linux, macOS, or Unix) in the AWS documentation.
If you use a firewall, you must configure it to allow the sites that your cluster requires access to.
注記Be sure to also review this site list if you are configuring a proxy.
- If you do not allow the system to manage identity and access management (IAM), then a cluster administrator can manually create and maintain IAM credentials. Manual mode can also be used in environments where the cloud IAM APIs are not reachable.
