2.7. Installing a cluster on AWS into an existing VPC
In OpenShift Container Platform version 4.5, you can install a cluster into an existing Amazon Virtual Private Cloud (VPC) on Amazon Web Services (AWS). The installation program provisions the rest of the required infrastructure, which you can further customize. To customize the installation, you modify parameters in the
install-config.yaml file before you install the cluster.
- 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 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.
- If you use a firewall, you must configure it to allow the sites that your cluster requires access to.
- 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.
