Visual Ansible Inventory Builder

Ansible inventory files define your infrastructure — which servers exist, how to connect to them, and what roles they serve. Writing these files by hand is error-prone, especially for complex multi-tier deployments with bastion hosts and group variables. This visual builder lets you define groups, add hosts, and configure SSH settings interactively, then generates a properly formatted inventory file. For SSH configuration, combine with our SSH Config Generator to create matching SSH config files, or use our Systemd Service Generator to manage services on your target hosts.

INI vs YAML Ansible Inventory Format

The INI format is the traditional Ansible inventory style, using [group_name] headers with one host per line. It is simple and widely supported. The YAML format is more modern, supports nested group hierarchies, and aligns with Ansible's YAML-first approach to playbooks and configuration. For new projects, YAML is generally recommended. Both formats support host variables (ansible_host, ansible_user, ansible_port) and group-level variables. For managing the services that Ansible deploys, use our Nginx Config Generator to create reverse proxy configurations for your web servers.

How to Use the Ansible Inventory Generator

  1. Choose your preferred output format (INI or YAML).
  2. Add host groups and name them (e.g., webservers, dbservers, loadbalancers).
  3. Add hosts to each group with their IP addresses and SSH settings.
  4. Optionally add group-level variables like ansible_user or ansible_become.
  5. Copy the generated inventory file and save it as hosts.ini or inventory.yml.

Common Use Cases

  • Building Ansible inventories for multi-tier web application deployments.
  • Configuring bastion and jump host setups for secure infrastructure access.
  • Generating YAML inventories for Ansible AWX or Ansible Tower projects.
  • Creating environment-specific inventories (dev, staging, production) for CI/CD pipelines.
  • Documenting server infrastructure with organized host groups and variables.

Frequently Asked Questions

What Ansible inventory formats does this tool support?

This tool generates inventories in both INI (traditional) and YAML (modern) formats. The INI format uses brackets for groups like [webservers], while YAML uses a hierarchical structure under the 'all' key with children and hosts.

Is this tool safe for my server inventory?

Yes. This tool runs 100% in your browser using client-side JavaScript. Your hostnames, IP addresses, and SSH credentials are never sent to any server, stored in any database, or logged anywhere.

What is the difference between INI and YAML inventory formats?

INI format is simpler and uses [group_name] sections with host entries on individual lines. YAML format supports deeper nesting, is more expressive for complex inventories with nested groups, and aligns with Ansible's preference for YAML-based configuration.

Can I add group-level variables?

Yes. Each group supports optional key-value variables like ansible_python_interpreter, ansible_become, ansible_ssh_common_args, or any custom variable. In INI format these appear in [group:vars] sections.

How do I configure a bastion or jump host setup?

Use the Bastion preset to automatically configure a jump host group with ProxyJump settings. The internal hosts will include ansible_ssh_common_args with the ProxyJump flag pointing to your bastion server.
