Chapter 1. Installation methods


You can install an OpenShift Container Platform cluster on vSphere by using a variety of installation methods. Each method is suitable for different use cases, such as disconnected environments or minimal configuration.

1.1. Assisted Installer

You can install OpenShift Container Platform with the Assisted Installer. This method requires no setup for the installation program and is ideal for connected environments such as vSphere. Installing with the Assisted Installer also provides integration with vSphere, enabling autoscaling.

1.2. Agent-based Installer

You can install an OpenShift Container Platform cluster on vSphere by using the Agent-based Installer, which boots on-premise servers in disconnected environments with a bootable image and supports custom network configurations.

You can install OpenShift Container Platform on vSphere by using installer-provisioned infrastructure, which automates the provisioning of cluster resources and supports disconnected network environments.

  • Installing a cluster on vSphere: You can install OpenShift Container Platform on vSphere by using installer-provisioned infrastructure installation with no customization.
  • Installing a cluster on vSphere with customizations: You can install OpenShift Container Platform on vSphere by using installer-provisioned infrastructure installation with the default customization options.
  • Installing a cluster on vSphere in a restricted network: You can install a cluster on VMware vSphere infrastructure in a restricted network by creating an internal mirror of the installation release content.

    You can use this method to deploy OpenShift Container Platform on an internal network that is not visible to the internet.

1.4. User-provisioned infrastructure installation

You can install OpenShift Container Platform on vSphere by using user-provisioned infrastructure, where you provision and manage all resources required by the cluster.

  • Installing a cluster on vSphere with user-provisioned infrastructure: You can install OpenShift Container Platform on VMware vSphere infrastructure that you provision or you can install OpenShift Container Platform on VMware vSphere infrastructure that you provision with customized network configuration options.
  • Installing a cluster on vSphere in a restricted network with user-provisioned infrastructure: OpenShift Container Platform can be installed on VMware vSphere infrastructure that you provision in a restricted network.
Important

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 vSphere platform and the installation process of OpenShift Container Platform. Use the user-provisioned infrastructure installation instructions as a guide; you are free to create the required resources through other methods.
