Ansible Tower Install and Configure

Introduction

Automation needs a boost of work in a limited time. Obtain the most of your investment with an enterprise automation platform that delivers agility and flexibility. No matter where you are on your automation journey with ansible tower.

Ansible Tower (previously ‘AWX’) is a web-based that makes Ansible easy to use. It will be the center for all of your automation tasks. The tower is free for usage for up to 10 nodes and comes bundled with fantastic support from Ansible.

It can be installed in many ways. OpenShift based deployments are limited to the only Tower. Deployment from Automation Hub on OpenShift is not possible. Deployed on Automation Hub. You can check more detail, refer to OpenShift Deployment and Configuration.

Ansible Tower is an excellent tool that does what the CLI tasks. It will complement but not replace, the tasks of automating the main tasks graphically, especially the monitoring dashboard tasks. It also greatly reduces the intimidation factor for those new to Ansible by introducing a much easier-to-understand visual tool. But for playbook creation, Ansible’s CLI is still your best option.
