This agentless architecture makes it lightweight and easy to implement across diverse environments.
The key features that make Ansible particularly valuable include:
- Declarative Language: Ansible uses YAML (YAML Ain’t Markup Language) for its playbooks, making automation scripts human-readable and accessible even to those without extensive programming experience.
- Idempotence: Ansible operations can be run multiple times without changing the result beyond the initial application, ensuring consistent system states.
- Extensive Module Library: With thousands of built-in modules, Ansible can automate virtually any IT system, from servers and network devices to cloud services and containers.
For openSUSE administrators, Ansible offers particular advantages. The platform’s flexibility aligns well with openSUSE’s enterprise-grade stability, making it ideal for both development environments and production deployments. Whether you’re managing a single server or orchestrating complex multi-tier applications, Ansible provides the scalability needed for growing infrastructure demands.
Prerequisites for Installing Ansible on openSUSE
Before proceeding with the installation, ensure your system meets the following requirements:
- A running openSUSE system (compatible with both Leap and Tumbleweed versions)
- Administrative (sudo) privileges on your system
- Basic familiarity with the command line interface
- Network connectivity for downloading packages
- Python 3 installed (comes pre-installed on most openSUSE distributions)
- SSH client installed for remote server management
It’s also recommended to update your system before installation to ensure compatibility with the latest packages:
sudo zypper update
Taking time to prepare your environment properly will help prevent common installation issues and ensure a smooth setup process for your Ansible environment.
Installation Methods Overview
When it comes to installing Ansible on openSUSE, you have several options to consider. Each method has distinct advantages depending on your specific requirements and environment. The three primary installation methods are:
- Official openSUSE Repositories: This is the simplest and most straightforward approach. Installation via official repositories ensures system compatibility and simplified updates through the package manager. This method is ideal for those who prefer stability and ease of maintenance.
- Python Pip Installation: Using Python’s package manager provides access to the latest Ansible versions, often ahead of distribution repositories. This method offers greater flexibility and control over versions, making it suitable for development environments or when specific features from newer releases are required.
- Source Code Installation: Installing from source gives you complete control over the installation process and access to development versions. This approach is best for advanced users who need to customize their installation or contribute to Ansible development.
Consider your specific use case, required features, and maintenance preferences when selecting the installation method. For most users, the repository installation provides the best balance of simplicity and stability.
Method 1: Installing Ansible Using openSUSE Official Repositories
Installing Ansible through openSUSE’s official repositories is the most straightforward method and ensures system compatibility. Follow these detailed steps to install Ansible using zypper
, the openSUSE package manager:
Step 1: Update System Packages
First, ensure your system’s package database is up-to-date:
sudo zypper refresh
This command refreshes the repository metadata, ensuring you have access to the latest package information.
Step 2: Install Ansible
Install Ansible directly from the repository with:
sudo zypper install ansible
The package manager will automatically resolve and install all required dependencies.
Step 3: Verify Installation
Check that Ansible was installed correctly by running:
sudo zypper info ansible
This will display detailed information about the installed Ansible package, including version and installation status.
Step 4: Check Ansible Version
Confirm the installation by checking the version:
ansible --version
This command displays not only the version number but also configuration file locations and Python version used by Ansible.
The repository installation method provides the advantage of receiving updates alongside your regular system maintenance. When openSUSE updates its repositories with new Ansible versions, you’ll receive these updates through the standard system update process.
Method 2: Installing Ansible via Python Pip
Installing Ansible through Python’s package manager (pip) often provides access to newer versions than those available in the distribution repositories. This method is particularly useful for development environments or when you need specific features from the latest releases.
Step 1: Install Python Dependencies
First, ensure you have Python and pip installed on your system:
sudo zypper install python3 python3-pip sshpass
These packages provide the foundation needed for installing and running Ansible.
Step 2: Install Ansible with Pip
Install Ansible globally using pip:
sudo pip3 install ansible
Alternatively, to install a specific version of Ansible:
sudo pip3 install ansible==X.Y.Z
Replace X.Y.Z with your desired version number (e.g., 2.12.1).
Step 3: Create a Virtual Environment (Optional)
For isolated installations, consider using Python virtual environments:
python3 -m venv ansible_env
source ansible_env/bin/activate
pip install ansible
This approach prevents conflicts with system packages and allows multiple Ansible versions to coexist on the same system.
Step 4: Verify the Installation
Confirm the installation was successful:
ansible --version
The command should display Ansible’s version and configuration details.
When using pip installation, keep in mind that you’ll need to manage updates manually through pip rather than through the system’s package manager. This provides more control but requires more active maintenance.
Method 3: Installing Ansible from Source
Installing Ansible from source gives you complete control over the installation process and access to development versions. This method is recommended for advanced users who require specific customizations or want to contribute to Ansible development.
Step 1: Install Required Dependencies
First, install the necessary development tools and dependencies:
sudo zypper install git python3-devel python3-pip python3-setuptools
These packages provide the development environment needed to build Ansible from source.
Step 2: Clone the Ansible Repository
Clone the official Ansible repository from GitHub:
git clone https://github.com/ansible/ansible.git
cd ansible
For a specific version, check out the appropriate tag:
git checkout stable-2.12 # Replace with your desired version
Step 3: Set Up the Environment
Set up your environment to use the development version:
source ./hacking/env-setup
This script configures your environment variables to use the development version of Ansible.
Step 4: Install Required Python Packages
Install the required Python dependencies:
pip3 install -r requirements.txt
This installs all the Python packages needed by Ansible.
Step 5: Verify the Installation
Confirm that the source installation works correctly:
ansible --version
The output should show that you’re using the development version from the local directory.
Source installation requires more maintenance as you’ll need to manually pull updates from the repository and rebuild when needed. However, it provides the advantage of immediate access to the latest features and fixes.
Verifying Your Ansible Installation
After installing Ansible, it’s crucial to verify that the installation was successful and is functioning correctly. Proper verification ensures that you can proceed with confidence to configuring and using Ansible.
Checking the Ansible Version
The most basic verification is checking the installed version:
ansible --version
This command should produce output similar to:
config file = /etc/ansible/ansible.cfg
configured module search path = ['/home/user/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
ansible python module location = /usr/lib/python3.x/site-packages/ansible
executable location = /usr/bin/ansible
python version = 3.x.x
The output provides valuable information about your Ansible installation, including the configuration file location, module search paths, and Python version.
Testing Basic Functionality
To verify that Ansible can execute commands properly, try a simple ping command against localhost:
ansible localhost -m ping
A successful response should look like:
localhost | SUCCESS => {
"changed": false,
"ping": "pong"
}
If you encounter errors during verification, check common issues like:
- Python version compatibility
- Path configurations
- Permission issues
- Missing dependencies
Proper verification at this stage prevents frustration later when attempting more complex automation tasks.
Configuring Ansible After Installation
Once Ansible is installed and verified, proper configuration is essential for optimal functionality. Ansible uses a hierarchical configuration system that allows for global, user-level, and project-specific settings.
Creating the Ansible Directory Structure
First, set up the recommended directory structure:
mkdir -p ~/ansible/playbooks
mkdir -p ~/ansible/inventory
mkdir -p ~/ansible/roles
This organization helps manage your Ansible resources efficiently as your automation grows.
Setting Up the Inventory File
The inventory file defines the hosts and groups that Ansible will manage. Create a basic inventory file:
nano ~/ansible/inventory/hosts
Add your servers (for example):
[webservers]
web1.example.com
web2.example.com
[dbservers]
db1.example.com
db2.example.com
[local]
localhost ansible_connection=local
This file organizes your servers into logical groups for targeted automation.
Configuring ansible.cfg
Create or modify the Ansible configuration file to customize behavior:
nano ~/ansible/ansible.cfg
Add basic configuration:
[defaults]
inventory = ~/ansible/inventory/hosts
remote_user = ansible
host_key_checking = False
roles_path = ~/ansible/roles
[privilege_escalation]
become = True
become_method = sudo
become_user = root
become_ask_pass = False
This configuration specifies your inventory location, remote user, and privilege escalation preferences.
Understanding configuration priorities is important. Ansible looks for configuration in the following order:
- ANSIBLE_CONFIG environment variable
ansible.cfg
in the current directory~/.ansible.cfg
(user’s home directory)/etc/ansible/ansible.cfg
(system-wide)
Proper configuration sets the foundation for effective Ansible usage across your infrastructure.
Setting Up SSH for Remote Management
Since Ansible relies on SSH for remote management, proper SSH configuration is critical for seamless operation. Follow these steps to set up secure, password-less authentication:
Generating SSH Keys
If you haven’t already generated an SSH key pair:
ssh-keygen -t rsa -b 4096
Press Enter at the prompts to accept the default location and create a key without a passphrase (for automation purposes).
Distributing SSH Keys to Remote Servers
To enable password-less authentication, copy your public key to each target server:
ssh-copy-id username@remote_server
Replace username
and remote_server
with your actual username and server hostname or IP address.
Testing SSH Connectivity
Verify that you can connect without a password:
ssh username@remote_server
If successful, you’ll connect without being prompted for a password.
SSH Configuration Options for Ansible
For advanced SSH configurations, create or edit ~/.ssh/config
:
nano ~/.ssh/config
Add custom configurations for your servers:
Host web*
User ansible
IdentityFile ~/.ssh/id_rsa
StrictHostKeyChecking no
Host db*
User ansible
IdentityFile ~/.ssh/id_rsa
Port 2222
This configuration allows for custom settings per server or server group.
Proper SSH setup eliminates authentication friction and makes your Ansible automation more reliable and secure.
Creating Your First Ansible Playbook
Now that Ansible is installed and configured, it’s time to create your first playbook. Playbooks are YAML files that define automation tasks and are the core of Ansible’s functionality.
Understanding Playbook Structure
Ansible playbooks consist of:
- Hosts: Specifies which servers to target
- Tasks: Actions to perform on those hosts
- Handlers: Triggered by tasks when changes occur
- Variables: Values that can be reused throughout the playbook
- Modules: Specific functions that perform the actual work
Creating a Simple Test Playbook
Create a new file for your playbook:
nano ~/ansible/playbooks/first-playbook.yml
Add the following content for a basic web server setup:
---
- name: Configure web server
hosts: local
become: yes
tasks:
- name: Update package cache
zypper:
update_cache: yes
- name: Install Apache web server
zypper:
name: apache2
state: present
- name: Start and enable Apache service
service:
name: apache2
state: started
enabled: yes
- name: Create a test web page
copy:
content: "<html><body><h1>My first Ansible-managed website</h1></body></html>"
dest: /srv/www/htdocs/index.html
owner: wwwrun
group: www
mode: '0644'
Running Your First Playbook
Execute the playbook with:
ansible-playbook ~/ansible/playbooks/first-playbook.yml
The output will show each task being executed and its result status.
Understanding this basic structure allows you to create increasingly complex automation for your infrastructure needs. As you become more familiar with Ansible, you can incorporate variables, conditions, loops, and roles to make your playbooks more powerful and reusable.
Managing Remote Servers with Ansible
After mastering basic playbooks, you can expand your Ansible usage to manage multiple remote servers efficiently. This section covers key concepts for remote server management.
Setting Up Inventory Groups
Organize your servers into logical groups in your inventory file:
[frontend]
front1.example.com
front2.example.com
[backend]
back1.example.com
back2.example.com
[production:children]
frontend
backend
[development]
dev.example.com
This hierarchical structure allows targeting specific server types or environments.
Targeting Specific Hosts or Groups
When running playbooks, you can target specific hosts or groups:
# Target all servers
ansible-playbook playbook.yml
# Target only frontend servers
ansible-playbook playbook.yml --limit frontend
# Target specific hosts
ansible-playbook playbook.yml --limit front1.example.com,back1.example.com
This flexibility allows precise control over your automation scope.
Using Ad-hoc Commands for Quick Tasks
For simple tasks, Ansible’s ad-hoc commands provide a quick alternative to playbooks:
# Check disk space on all servers
ansible all -a "df -h"
# Update packages on backend servers
ansible backend -b -m zypper -a "name=* state=latest"
# Restart a service on a specific server
ansible front1.example.com -b -m service -a "name=apache2 state=restarted"
Ad-hoc commands are perfect for one-off tasks that don’t require the structure of a full playbook.
Privilege Escalation on Remote Systems
Many operations require root privileges. Control how Ansible escalates privileges:
- name: Configure system settings
hosts: all
become: yes # Enable privilege escalation
become_method: sudo # Use sudo for escalation
become_user: root # Escalate to root user
tasks:
- name: Update system configuration
lineinfile:
path: /etc/sysctl.conf
line: "net.ipv4.ip_forward=1"
These settings ensure Ansible can perform administrative tasks securely across your infrastructure.
Effective remote server management with Ansible requires understanding these concepts and applying them to your specific environment needs.
Common Issues and Troubleshooting
Even with careful planning, you may encounter issues when working with Ansible on openSUSE. This section addresses common problems and their solutions.

sudo zypper update ansible
This method ensures compatibility with your openSUSE version and maintains system stability.
Updating Pip Installations
If you installed Ansible using pip, update it with:
sudo pip3 install --upgrade ansible
To update to a specific version:
sudo pip3 install --upgrade ansible==X.Y.Z
Remember that pip updates bypass the distribution’s package testing, so consider testing updates in a non-production environment first.
Managing Dependencies
Ansible depends on various Python packages that may need updating independently:
pip list --outdated | grep ansible
pip install --upgrade <package-name>
This helps ensure all components remain compatible.
Version Compatibility Considerations
Before updating, check the Ansible release notes for:
- Breaking changes that might affect your playbooks
- Deprecated features you may be using
- New requirements that might impact your environment
- Compatibility with your openSUSE version
Establishing a testing workflow for Ansible updates helps prevent unexpected issues in production environments.
Best Practices for Using Ansible on openSUSE
To maximize the benefits of Ansible on openSUSE, follow these best practices that experienced administrators have developed over years of usage.
Directory Structure Organization
Maintain a clean, logical directory structure:
ansible/
├── inventory/
│ ├── production
│ ├── staging
│ └── development
├── group_vars/
│ ├── all.yml
│ └── webservers.yml
├── host_vars/
│ └── specific-host.yml
├── roles/
│ ├── common/
│ ├── webserver/
│ └── database/
└── playbooks/
├── site.yml
├── webserver.yml
└── database.yml
This organization improves maintainability and makes collaboration easier, especially in large environments.
Version Control for Playbooks
Store your Ansible content in a version control system like Git:
# Initialize a Git repository
cd ~/ansible
git init
# Create a .gitignore file
echo "*.retry" > .gitignore
# Commit your files
git add .
git commit -m "Initial Ansible configuration"
Version control provides history tracking, collaboration features, and rollback capabilities.
Documentation Standards
Document your Ansible infrastructure thoroughly:
- Add comments in playbooks to explain complex tasks
- Maintain a README file for each role explaining its purpose and usage
- Document variables and their expected values
- Create a centralized wiki or documentation site for your Ansible practices
Good documentation reduces onboarding time for new team members and helps prevent errors.
Testing Strategies
Implement testing procedures for your Ansible code:
- Use
--check
mode to simulate changes before applying them - Create staging environments that mirror production
- Utilize
ansible-lint
to check playbook quality - Implement molecule for role testing
Thorough testing prevents unexpected issues when deploying to production systems.
Security Considerations
Prioritize security in your Ansible implementation:
- Use vault for encrypting sensitive data:
ansible-vault create secrets.yml
- Regularly rotate SSH keys and credentials
- Apply the principle of least privilege for Ansible users
- Review playbooks for security implications before deployment
- Use specific task delegation rather than running everything as root
