Installation Overview

This section covers installing Ascender Automation Platform using the ascender-install tool across supported Kubernetes platforms.

The installer automates cluster provisioning (where supported), Ascender deployment, and optional Ascender Pro setup through a single configuration file and the ./setup.sh script.

Quick Start

New to Ascender? The K3s Quick Start gets you up and running on a single machine in minutes with no cloud account required.

Ascender Pro

Ascender Pro adds analytics, reporting, and log aggregation on top of Ascender. You can install it alongside Ascender using the same installer. See the Ascender Pro Installation Guide for configuration and setup, or contact us if you're interested in getting access.

Prerequisites

  • An x86_64 machine running Rocky Linux version 8 or 9 to run the installer from. For on-premise deployments (K3s, RKE2), this can be the same server you are installing the cluster on. For cloud platforms (EKS, GKE, AKS), we recommend a small Rocky Linux 9 admin server to run these commands from.
  • git installed (sudo dnf install -y git)
  • Root or sudo access on the installing machine
  • For cloud platforms: the appropriate CLI tool installed and authenticated (AWS CLI, gcloud, or Azure CLI)
