Code files for course0:03
What is Ansible1:34
Discover how Ansible automates configuration management, application deployment, and remote job execution as an open source tool, and operates agentless via SSH with only Python on servers.
Install Ansible on Linux8:51
Install Ansible on Linux across Ubuntu, Amazon Linux, and Red Hat Linux by verifying Python, installing via apt, yum, or pip, and testing connectivity to localhost.
Inventory file2:53
Master the Ansible inventory file by organizing hosts and groups in ini or yaml formats, specify per-host and per-group variables, ranges, and parent-child structures to apply playbooks to groups.
Preparing On-prem VMs, create a SSH Key6:50
Prepare on-prem or cloud VMs by creating a passwordless sudo user, generating and uploading an SSH key, and establishing passwordless SSH for a load balancer and web servers setup.
Notes0:14
Preparing AWS VMs, import the SSH Key4:13
Prepare AWS infrastructure by importing the SSH public key as a key pair, create three Ubuntu virtual machines with security groups, and connect to web servers and a load balancer.
Create a inventory file for course2:05
Create an inventory file for this course using the previous lesson’s file, configuring two web servers and a load balancer with the same user and ssh key, using ip addresses.
Ansible Config4:52
Set up and use an ansible config file to manage inventory, apply commands with -i and group names, verify hosts with ping, and enable Python 3 in the config.
Ad-hoc Commands3:14
learn how ad hoc commands in Ansible run direct tasks from the terminal without writing a playbook, using modules like ping and shell to target hosts or web servers.
Ansible Playbook6:55
Create and run an Ansible playbook in yaml to install nginx on web servers, use become for sudo, and employ apt, service, and a handler for restarts.
Condition "when"4:54
Use the Ansible condition when to run tasks on Debian-like systems, and manage yum vs apt with OS family facts to create universal playbooks across Linux distributions.
Ansible Variables3:40
Define and use Ansible variables to parameterize package installation, applying names like nginx in playbooks. Manage environment-specific values with inventory groups and variables files for different environments.
Roles in Ansible5:05
Learn how Ansible roles provide a skeleton directory structure to organize tasks, handlers, templates, and variables, enabling reusable, shareable playbooks with an nginx role.
Ansible templates6:35
Learn how to use Ansible templates with Jinja2 to generate dynamic files from host variables, add a template task, and deploy a rendered nginx homepage.
Role for Load Balancer13:28
Create and deploy a load balancer role with HAProxy using Ansible, updating inventory, templates, handlers, and playbooks to distribute traffic across multiple web servers.

Requirements

Participants in this course should have familiarity with Linux and possess knowledge of basic Linux commands.
Participants in this course should be able to create a virtual machines on local laptop (VirtualBox), on VMware/HyperV or in Cloud.
