Certainly! Here's a basic Ansible cheat sheet to help you quickly reference some common commands and concepts:
Ansible Commands:
ansible-playbook: Run an Ansible playbook to configure systems.
ansible: Run a single Ansible command on a set of hosts.
ansible-galaxy: Manage Ansible roles and collections.
Ansible Playbook Structure:
Hosts: Define the target hosts or groups in the playbook.
Tasks: Specify the actions to be performed on the target hosts.
Handlers: Define tasks to be triggered by other tasks.
Variables: Set variables for use in the playbook.
Roles: Organize tasks, handlers, and variables into reusable units.
Common Modules:
apt/yum: Manage packages on Debian/Ubuntu or Red Hat/CentOS systems.
copy/template: Copy files or use templates to configure files on remote hosts.
service/systemd: Manage services on Linux systems.
user/group: Manage users and groups on remote hosts.
file: Manage files and directories on remote hosts.
Ansible Configuration:
ansible.cfg: Main configuration file for Ansible.
Inventory: Define the hosts and groups that Ansible will manage.
Roles: Organize tasks, handlers, and variables into reusable units.
Best Practices:
Idempotence: Ensure that playbooks can be run multiple times without changing the system if no changes are needed.
Modularity: Organize playbooks into reusable roles and tasks.
Documentation: Include comments and documentation in playbooks for clarity and maintainability.
Testing: Use Ansible's testing tools to validate playbooks and roles.
