Red Hat Summit3.3. Installing a cluster on AWS with customizations
In OpenShift Container Platform version 4.21, you can install a cluster on Amazon Web Services (AWS) by using installer-provisioned infrastructure with customizations, including network configuration options. In each, you modify parameters in the install-config.yaml file before you install the cluster. By customizing your network configuration, your cluster can coexist with existing IP address allocations in your environment and integrate with existing MTU and VXLAN configurations. You must set most of the network configuration parameters during installation, and you can modify only kubeProxy configuration parameters in a running cluster.
The scope of the OpenShift Container Platform installation configurations is intentionally narrow. It is designed for simplicity and ensured success. You can complete many more OpenShift Container Platform configuration tasks after an installation completes.
3.3.1. Prerequisites
- You reviewed details about the OpenShift Container Platform installation and update processes.
- You read the documentation on selecting a cluster installation method and preparing it for users.
You configured an AWS account to host the cluster.
중요If 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-term 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 configured it to allow the sites that your cluster requires access to.
