System requirements

Use this information when planning your installation of containerized Ansible Automation Platform.

Prerequisites
Copy link

  • Configure a dedicated non-root user on the Red Hat Enterprise Linux host.
    • This user requires sudo or other Ansible supported privilege escalation (sudo is recommended) to perform administrative tasks during the installation.
    • This user is responsible for the installation of containerized Ansible Automation Platform.
    • This user is also the service account for the containers running Ansible Automation Platform.
  • For managed nodes, configure a dedicated user on each node. Ansible Automation Platform connects as this user to run tasks on the node. For more information about configuring a dedicated user on each node, see Prepare the managed nodes.
  • For remote host installations, configure SSH public key authentication for the non-root user. For guidelines on setting up SSH public key authentication for the non-root user, see How to configure SSH public key authentication for passwordless login.
  • Ensure the Red Hat Enterprise Linux host has internet access if you are using the default online installation method.
  • Open the appropriate network ports if you have a firewall in place. For more information about the ports to open, see Container enterprise topology in Tested deployment models.
Important

Podman does not support storing container images on an NFS share. To use an NFS share for the user home directory, set up the Podman storage backend path outside of the NFS share. For more information, see Rootless Podman and NFS.

Table 1. System configuration
Type Description Notes

Subscription
  • Valid Red Hat Ansible Automation Platform subscription
  • Valid Red Hat Enterprise Linux subscription (to consume the BaseOS and AppStream repositories)

Operating system
  • Red Hat Enterprise Linux 9.4 or later minor versions of Red Hat Enterprise Linux 9.
  • Red Hat Enterprise Linux 10 or later minor versions of Red Hat Enterprise Linux 10.

CPU architecture

x86_64, AArch64, s390x (IBM Z), ppc64le (IBM Power)

ansible-core

  • RHEL 9: installation program uses ansible-core 2.14, Ansible Automation Platform operation uses ansible-core 2.16.
  • RHEL 10: installation program uses ansible-core 2.16, Ansible Automation Platform operation uses ansible-core 2.16.
  • The installation program uses the ansible-core package from the RHEL AppStream repository.
  • Ansible Automation Platform bundles ansible-core 2.16 for operation, so you do not need to install it manually.

Browser

A currently supported version of Mozilla Firefox or Google Chrome.

Database
  • For Ansible Automation Platform managed databases: PostgreSQL 15.
  • For customer provided (external) databases: PostgreSQL 15, 16, or 17.
  • External (customer supported) databases require International Components for Unicode (ICU) support.
  • External databases using PostgreSQL 16 or 17 must rely on external backup and restore processes. Backup and restore functionality is dependent on utilities provided with PostgreSQL 15.

Database requirements

Ansible Automation Platform can work with two varieties of database:

  1. Database installed with Ansible Automation Platform - This database consists of a PostgreSQL installation done as part of an Ansible Automation Platform installation using PostgreSQL packages that Red Hat provides.
  2. Customer provided or configured database - This is an external database that the customer provides, whether on bare metal, virtual machine, container, or cloud hosted service.

Ansible Automation Platform requires a customer provided (external) database to have International Components for Unicode (ICU) support.
