Ways of Working – Ansible

1. Ensure you have list of all the steps (commands) which are working.
2. Take each command find equivelent module in Ansible
3. Write a playbook (yaml) where we list the modules in a specific structure.

Summary

• We need to know the playbook format i.e. YAML
• Expressing modules in YAML form

Finding equivelent modules for commands in Ansible

• Ansible has a very large set of modules
• In addition to these modules ansible has a larger community of third party reusable assets
• To find the right module lets do the exercise

Lets look at website installation steps

• steps to install nginx

sudo apt update
sudo apt install nginx -y
sudo systemctl enable nginx.service
sudo systemctl start nginx.service

• Now download the website

sudo apt install unzip
cd /tmp
wget https://templatemo.com/tm-zip-files-2020/templatemo_589_lugx_gaming.zip
unzip templatemo_589_lugx_gaming.zip
cd templatemo_589_lugx_gaming/
sudo cp --recursive . /var/www/html/

• Google for <command> in ansible will work for 90% of the cases.

sudo apt update => apt update => command is apt  action is update
sudo apt install nginx -y => apt => command install is action

• Any command

ping google.com
systemctl restart nginx
command <args>

• Module name
  
• Parameters
  
• Examples: Will give basic usage
• Prompt to understand command

You are linux expert, i will give you the command and explain what it does breifly

Lets list out command, equivelent module and necessary parameters

Command	Module	Parameters
apt update	ansible.builtin.apt	update_cache => true
apt install nginx	ansible.builtin.apt	state => present, name => nginx
systemctl enable nginx.service	ansible.builtin.systemd_service	enabled => true, name => nginx.service
sudo systemctl start nginx.service	ansible.builtin.systemd_service	name => nginx.service, state => started
apt install unzip
wget https://templatemo.com/tm-zip-files-2020/templatemo_589_lugx_gaming.zip	ansible.builtin.get_url	url, dest => /tmp/templatemo_589_lugx_gaming.zip.zip
unzip templatemo_589_lugx_gaming.zip	ansible.builtin.unarchive	src => url, remote_src => true, dest => /var/www/html/

• Exercise: Findout steps to install tomcat 10 with openjdk 21 on ubuntu server and comeup with this table.
