You can install OpenShift Container Platform on on-premise hardware or on-premise VMs using the Assisted Installer. Installing OpenShift Container Platform using the Assisted Installer supports both x86-64 and arm64 CPU architectures.
The OpenShift Container Platform Assisted Installer is a user-friendly installation solution offered on the Red Hat Hybrid Cloud Console. The Assisted Installer supports the various deployment platforms with a focus on bare metal and vSphere infrastructures.
The Assisted Installer provides installation functionality as a service. This software-as-a-service (SaaS) approach has the following advantages:
Web user interface: The web user interface performs cluster installation without the user having to create the installation configuration files manually.
No bootstrap node: A bootstrap node is not required when installing with the Assisted Installer. The bootstrapping process executes on a node within the cluster.
Hosting: The Assisted Installer hosts:
The installation configuration
A discovery ISO
Streamlined installation workflow: Deployment does not require in-depth knowledge of OpenShift Container Platform. The Assisted Installer provides reasonable defaults and provides the installer as a service, which:
Eliminates the need to install and run the OpenShift Container Platform installer locally.
Ensures the latest version of the installer up to the latest tested z-stream releases. Older versions remain available, if needed.
Enables building automation by using the API without the need to run the OpenShift Container Platform installer locally.
Advanced networking: The Assisted Installer supports IPv4/IPv6 dual stack networking, NMState-based static IP addressing, and an HTTP/S proxy.
Pre-installation validation: The Assisted Installer validates the configuration before installation to ensure a high probability of success. Validation includes:
Ensuring network connectivity
Ensuring sufficient network bandwidth
Ensuring connectivity to the registry
Ensuring time synchronization between cluster nodes
Verifying that the cluster nodes meet the minimum hardware requirements
Validating the installation configuration parameters
REST API: The Assisted Installer has a REST API, enabling automation.
The Assisted Installer supports installing OpenShift Container Platform on premises in a connected environment, including with an optional HTTP/S proxy. It can install the following:
Highly available OpenShift Container Platform or Single Node OpenShift (SNO)
OpenShift Container Platform on bare metal or vSphere with full platform integration, or other virtualization platforms without integration
Optionally OpenShift Virtualization and OpenShift Data Foundation (formerly OpenShift Container Storage)
The user interface provides an intuitive interactive workflow where automation does not exist or is not required. Users may also automate installations using the REST API.
