====Installation====
To run Ansible Playbooks, install automation content navigator (ansible-navigator) on your control node and download an execution environment. Hosts that are managed by Ansible do not need to have ansible-navigator installed; you only need to install that tool on the control node from which you run Ansible Playbooks.

Python 3.8 or later needs to be installed on the control node before installing the ansible-core package.

You need a valid Red Hat Ansible Automation Platform subscription to install automation content navigator on your control node.

If you have activated Simple Content Access for your organization in the Red Hat Customer Portal, then you do not need to attach the subscription to your system.

The installation process is as follows:

you would need to use subscription-manager to register your system with Red Hat Subscription Management and enable the ansible-automation-platform-2.2-for-rhel-9-x86_64-rpms repository first.

===Install automation content navigator on your control nodes.===
<code>
[user@controlnode ~]$ sudo dnf install ansible-navigator</code>

Verify that automation content navigator is installed on the system.
<code>
[user@controlnode ~]$ ansible-navigator --version
ansible-navigator 2.1.0 </code>

Log in to the container registry.

<code>
[user@controlnode ~]$ podman login registry.redhat.io
Username: your-registry-username
Password: your-registry-password
Login Succeeded! </code>

Download the container image for the execution environment that you plan to use with automation content navigator. (Automation content navigator might also automatically download the default execution environment when you run the ansible-navigator command.)

<code>
[user@controlnode ~]$ podman pull \
> registry.redhat.io/ansible-automation-platform-22/ee-supported-rhel8:latest </code>

Display the list of locally available container images to verify that the image was downloaded.

<code>
[user@controlnode ~]$ ansible-navigator images
  Image                    Tag      Execution environment         Created         Size
