Red Hat Ansible Automation Platform system requirements - Red Hat Ansible Automation Platform

A resilient deployment requires 10 virtual machines with a minimum of 16 gigabytes (GB) of RAM and 4 virtual CPUs (vCPU). See Choose a deployment method and topology for more information on topology options.

Table 1. Base system
Type	Description	Notes
Subscription	Valid Red Hat Ansible Automation Platform subscription
Operating system	Red Hat Enterprise Linux 9.6 or later minor versions of Red Hat Enterprise Linux 9	Red Hat Ansible Automation Platform are also supported on OpenShift, see Installing on OpenShift Container Platform for more information.
CPU architecture	x86_64, AArch64, s390x (IBM Z), ppc64le (IBM Power)	IBM Z (s390x) and IBM Power (ppc64le) are not supported in Ansible Automation Platform 2.7. For IBM architecture support, use Ansible Automation Platform 2.6.
Ansible-core	Ansible-core version 2.16 or later	Ansible Automation Platform uses the system-wide ansible-core package to install the platform, but uses ansible-core 2.16 for both its control plane and built-in execution environments.
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.
IP version	IPv4, IPv6 (single-stack and dual-stack)

Table 2. Virtual machine requirements
Component	RAM	vCPU	Disk IOPS	Storage
Platform gateway	16GB	4	3000	60GB minimum
Control nodes	16GB	4	3000	80GB minimum with at least 20GB available under `/var/lib/awx`
Execution nodes	16GB	4	3000	60GB minimum
Hop nodes	16GB	4	3000	60GB minimum
Automation hub	16GB	4	3000	60GB minimum with at least 40GB allocated to `/var/lib/pulp`
Database	16GB	4	3000	100GB minimum allocated to `/var/lib/pgsql`
Event-Driven Ansible controller	16GB	4	3000	60GB minimum

Note:

These are minimum requirements and can be increased for larger workloads in increments of 2x (for example 16GB becomes 32GB and 4 vCPU becomes 8vCPU). See Horizontally scale tested deployment models to improve performance for more information.

Repository requirements

Enable the following repositories only when installing Red Hat Ansible Automation Platform:

RHEL BaseOS
RHEL AppStream

Note:

If you enable repositories besides those mentioned above, the Red Hat Ansible Automation Platform installation could fail unexpectedly.

The following are necessary for you to work with project updates and collections:

Ensure that the Network ports and protocols table are available for successful connection and download of collections from automation hub or Ansible Galaxy server.

Additional notes for Red Hat Ansible Automation Platform requirements

The Ansible Automation Platform database backups are staged on each node at /var/backups/automation-platform through the variable backup_dir. You might need to mount a new volume to /var/backups or change the staging location with the variable backup_dir to prevent issues with disk space before running the ./setup.sh -b script.
If performing a bundled Ansible Automation Platform installation, the installation setup.sh script attempts to install ansible-core (and its dependencies) from the bundle for you.
If you have installed Ansible-core manually, the Ansible Automation Platform installation setup.sh script detects that Ansible has been installed and does not attempt to reinstall it.

Note:

You must use Ansible-core, which is installed by using DNF. Ansible-core version 2.16 is required for versions 2.6 and later.
