1. Introduction

In this repo, I want to explore some of the basic Ansible features that allow you to manage your VMs.

2. Setting up a local environment

Manage the new VM

kcli create plan -f docs/kcli-template-rhel92.yaml rhel92 # Create a basic plan with one VM
kcli plan -s rhel92 # Start the plan
kcli plan -w rhel92 # Stop the plan
kcli list vm        # Show VMs status
kcli plan -d rhel92 # Delete the plan

Add the VM to the /etc/hosts

sudo bash -c 'echo "192.168.122.100 rhel92.vm" >> /etc/hosts'

Copy your ssh keys

ssh-copy-id rhel92.vm

3. Ansible Automation Platform

Red Hat Ansible Automation Platform is an end-to-end automation platform to configure systems, deploy software, and orchestrate advanced workflows.

3.1. Vi useful configuration

autocmd FileType yaml setlocal ai ts=2 sw=2 et

4. Ansible basics

4.1. Get documentation

List all the available modules

# List available images
ansible-navigator images

# List available modules
ansible-navigator doc -l

# List available collections
ansible-navigator collections

# Get documentation for one module
ansible-navigator -s doc module_name

# Create a role from scratch
ansible-galaxy init alvaro.testing

Autogenerate ansible config file with defaults

ansible-navigator config init --disabled > ansible.cfg

Autogenerate ansible-navigator YAML with defaults

ansible-navigator settings --sample > ansible-navigator.yml

4.2. Ansible Vault

# Create secret
ansible-vault create --vault-password-file=vault-pass.txt group_vars/web/vault.yml

# Edit Secret
ansible-vault edit --vault-password-file=vault-pass.txt group_vars/web/vault.yml

# Execute Plays with password
ansible-navigator run -m stdout --vault-password-file=vault-pass.txt plays/20_variables.yaml

4.3. Gather Facts

ansible-navigator run -m stdout plays/30_facts.yaml

4.4. Loops, Conditionals, and Handlers

ansible-navigator run -m stdout --ask-become-pass plays/40_task_control.yaml

4.5. Manage Files

ansible-navigator run -m stdout plays/50_deploy_files.yaml

4.6. Complex Plays

ansible-navigator run -m stdout --ask-become-pass plays/60_complex_plays.yaml

4.7. Roles and Collections

Install existing roles and collections

# Install a Role
ansible-galaxy role install -r roles/requirements.yml

# Install a Collection
ansible-galaxy collection install -r collections/requirements.yml -p collections

KCS about System Roles availability and support: https://access.redhat.com/articles/3050101

ansible-navigator run -m stdout --ask-become-pass plays/70_roles_and_collections.yaml

4.8. Manage Subscriptions

ansible-navigator run -m stdout --ask-become-pass plays/90_rh_subs.yaml

💡	I strongly recommend the exercises proposed by mateuszstompor in his repo rhce-ex294-exam. He has some generic exercises that provide a good starting point to make sure that you control the topics that appear in the RHCE exam for RHEL 9.
