Is it possible to write Ansible hosts/inventory files in YAML?

问题

In the best practices page, there is an example that uses hosts.yml for hosts files:

In the docs, however, I can only find the INI syntax for writing hosts files.

What is the syntax for the inventory files in YAML?

回答1:

Yes.

It's been deprecated in version 0.6 in 2012 and reintroduced in a commit first included in version 2.1 in 2016.

The example file on GitHub contains the guidelines and examples:

Comments begin with the '#' character

Blank lines are ignored

Top level entries are assumed to be groups

Hosts must be specified in a group's hosts: and they must be a key (: terminated)

groups can have children, hosts and vars keys

Anything defined under a hosts is assumed to be a var

You can enter hostnames or ip addresses

A hostname/ip can be a member of multiple groups

Ex 1: Ungrouped hosts, put in 'ungrouped' group
ungrouped:
  hosts:
      green.example.com:
          ansible_ssh_host: 191.168.100.32
      blue.example.com:
      192.168.100.1:
      192.168.100.10:
Ex 2: A collection of hosts belonging to the 'webservers' group
webservers:
  hosts:
      alpha.example.org:
      beta.example.org:
      192.168.1.100:
      192.168.1.110:
Ex 3: You can create hosts using ranges and add children groups and vars to a group. The child group can define anything you would normally add to a group
testing:
  hosts:
      www[001:006].example.com:
  vars:
      testing1: value1
  children:
      webservers:
          hosts:
              beta.example.org:

Previous answers are correct but here is simple hosts.yaml and INI like side by side in the screenshot and I'm just copying the actual hosts.yaml here too so if you want copy and paste and edit it for yourself

--- 
all: 
  hosts:               
    xmp: 
      ansible_connection: ssh
      ansible_host: "192.1.0.1"
      ansible_port: 7822
      ansible_user: nanoseco

I just discovered Ansible INI to YAML inventory converter on github which worked fine for me:

This repository contains a Python script for converting Ansible inventories in INI format to YAML format.

For some reason, the conversion ended up with host ranges ([01:03]) being seperated by = instead of the shown and correct :.
