如何在终端查看Ansible文档？能否通过命令查看指定URL的Play关键词信息？

Hey there! Let's break down your questions about accessing Ansible documentation right from your terminal:

1. How to View Ansible Documentation in the Terminal #

The primary tool for this is ansible-doc—it's built into Ansible and lets you access all module, plugin, and playbook keyword docs without leaving your terminal. Here are the most common use cases:

• View documentation for a specific module:
  Run ansible-doc <module_name> to get full details, examples, and parameter info. For example:

  ansible-doc apt
  

  Add the -s flag to get a snippet of the module's parameter structure (great for copying into playbooks):

  ansible-doc -s apt
  

• List all available modules:
  Use --list to see every module installed with your Ansible version:

  ansible-doc --list
  

• View documentation for other plugin types:
  Ansible has various plugin types (inventory, callback, lookup, etc.). Use the -t flag to specify the type. For example, to check an inventory plugin:

  ansible-doc -t inventory aws_ec2
  

2. Getting Playbook Keyword Info (Matching the Official Play Keywords Docs) #

Absolutely! You can use ansible-doc to access the exact same Playbook keyword information that's in the official docs. The key is targeting the playbook type with the -t flag.

• View all Playbook keywords:
  Run this command to see every play-level keyword and its details:

  ansible-doc -t playbook all
  

• View details for a specific Play keyword:
  If you want info on a single keyword (like hosts, become, or the top-level play keyword itself), specify it directly:

  ansible-doc -t playbook play
  

  This will give you the same description, parameters, and examples you'd find in the official Play keywords reference. The content is tied to your installed Ansible version, so it'll match the official docs for that exact release.

Note: The ansible command itself doesn't handle direct documentation lookup for playbook keywords—ansible-doc is the dedicated tool for all Ansible documentation needs in the terminal.
