12.5.7. Obtaining the installation program
Before you install OpenShift Container Platform, download the installation file on a local computer.
- You must install the cluster from a computer that uses Linux or macOS.
- You need 500 MB of local disk space to download the installation program.
- Access the Infrastructure Provider page on the Red Hat OpenShift Cluster Manager site. If you have a Red Hat account, log in with your credentials. If you do not, create an account.
Navigate to the page for your installation type, download the installation program for your operating system, and place the file in the directory where you will store the installation configuration files.重要
The installation program creates several files on the computer that you use to install your cluster. You must keep both the installation program and the files that the installation program creates after you finish installing the cluster.重要
Deleting the files created by the installation program does not remove your cluster, even if the cluster failed during installation. You must complete the OpenShift Container Platform uninstallation procedures outlined for your specific cloud provider to remove your cluster entirely.
Extract the installation program. For example, on a computer that uses a Linux operating system, run the following command:
$ tar xvf <installation_program>.tar.gz
From the Pull Secret page on the Red Hat OpenShift Cluster Manager site, download your installation pull secret as a
.txtfile. This pull secret allows you to authenticate with the services that are provided by the included authorities, including Quay.io, which serves the container images for OpenShift Container Platform components.
