This video is to demonstrate how to patch Linux server from Ansible tower. What If a task is based on status of a certain command on another machine?. You will need a Linux or Mac machine to use as an Ansible server, but Windows computers can be managed with Ansible. Note: There is a “Terraform” task available on VSTS marketplace, it has great capabilities of running templates and using storage account as a backend, but it’s currently Windows only, while Ansible task is Linux based task – for that reason this example was written to use shell scripts. First, some Linux distributions have the adduser command, wihch is a shortcut (with sensible defaults) to the useradd command. Objective The objective is to install Ansible on Ubuntu 18. Using Ansible to configure an Oracle Linux 7. I am thinking about pointing Ansible to my local repository for updates. I do not want to reboot these servers every time there is an update to the kernel, I only want to reboot for example every 2 months. The role Reboot-And-Wait you can find here. My Ansible server is running Ubuntu 17. It assumes knowledge of SSH, Linux, Git, virtual machines and basic programming. I want to walk you through the steps of installing the official Ansible release on Ubuntu Server 18.
