Since <code>Ansible 2.2</code>, the <code>include_vars</code> (<a href="https://docs.ansible.com/ansible/2.5/modules/include_vars_module.html" rel="nofollow noreferrer">link</a>) module has been expanded quite a bit.

It's now possible to do something like:

<pre><code>- include_vars:
 name: 'apps'
 dir: '../vars'
 extensions:
 - 'yaml'
 - 'yml'
</code></pre>

<code>name</code> is the key there. From the module page:

<blockquote>
 The name of a variable into which assign the included vars. If omitted (null) they will be made top level vars.
</blockquote>

This allows you to convert:

<pre><code>vars/
 app1.yml
 app2.yml
 ...
</code></pre>

app1.yml:

<pre><code>name: app1
git_repo: https://github.com/philgyford/app1.git
# ...
</code></pre>

app2.yml:

<pre><code>name: app2
git_repo: https://github.com/philgyford/app2.git
# ...
</code></pre>

Into...

<pre><code>apps:
 - name: app1
 git_repo: https://github.com/philgyford/app1.git
 # ...
 - name: app2
 git_repo: https://github.com/philgyford/app2.git
 # ...
</code></pre>

Well, you cannot directly build an array, but you can achieve the same effort with a dict.

Suppose you want to construct an array:

<pre><code>[{
 name: 'bob',
 age: 30
}, {
 name: 'alice',
 age: 35 
}]
</code></pre>

You can put each element in a file like:

<h3>bob.yml</h3>

<pre><code>bob:
 name: bob
 age: 30
</code></pre>

<h3>alice.yml</h3>

<pre><code>alice:
 name: alice
 age: 35
</code></pre>

Place these files in the same dir (e.g. <code>user</code>), then use <code>include_vars</code> to load the whole dir:

<pre><code>- name: Include vars
 include_vars:
 name: users
 dir: user
</code></pre>

This will give you a dict <code>users</code>: 

<pre><code>users:
 alice:
 name: alice
 age: 35
 bob:
 name: bob
 age: 30
</code></pre>

User the <code>dict2items</code> filter in ansible, you get the array you want

Wanted to post a possible alternate solution by getting a list of variables that match a pattern, then you can just process all those variables, sorta manual merge.

The following code block gives an example of pulling all variables that match a specific pattern and looping. you could set a new fact with them merged, or simply process them all individually.

<pre><code>- name: "debug2" debug:
 msg: "value is: {{ lookup('vars', item) }} " 
 loop: "{{ hostvars[inventory_hostname] | select('match', '^linux_hosts_entries') |list }}"
</code></pre>

see the following <a href="https://groups.google.com/forum/#!topic/ansible-project/Ssnk6exNjNs" rel="nofollow noreferrer">post</a> for further details.

blocks|key|472781|text|如果不想更改哈希的默认行为。我建议你我的解决方案。我定义了多个变量(使用相同的regex)，当Ineed合并它们时，我从hostvars中过滤它们。例：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|472782|-+name:+Combine+variables+with+prefix+enabled_services

If you don't want to change default behavior of hash. I suggest you my solution.
I define multiple variables (with same regex) when Ineed to merge them, I filter them from hostvars. Eg:

<pre><code>- name: Combine variables with prefix enabled_services
 debug:
 msg: "{{ hostvars[inventory_hostname].keys() | map('regex_search', 'enabled_services.*') | select('string') | list }}"

Use attribute <a href="https://docs.ansible.com/ansible/latest/modules/include_vars_module.html#parameter-name" rel="nofollow noreferrer">name</a> and put the included variables into the dictionaries. Fit the name of the dictionaries to your needs. For example
<pre class="lang-yaml prettyprint-override"><code> - name: Load var files
 include_vars:
 file: &quot;{{ item }}&quot;
 name: &quot;incl_vars_{{ item|basename|splitext|first }}&quot;
 with_fileglob:
 - vars/*.yml
</code></pre>
Then, use the lookup plugin <a href="https://docs.ansible.com/ansible/latest/plugins/lookup/varnames.html#varnames-lookup-matching-variable-names" rel="nofollow noreferrer">varnames</a> (New in version 2.8.), find all dictionaries, and iterate the list. In the loop use the lookup plugin <a href="https://docs.ansible.com/ansible/latest/plugins/lookup/vars.html#vars-lookup-templated-value-of-variables" rel="nofollow noreferrer">vars</a> (New in version 2.5.) and create the list apps. For example
<pre class="lang-yaml prettyprint-override"><code> - set_fact:
 apps: &quot;{{ apps|default([]) + [lookup('vars', item)] }}&quot;
 loop: &quot;{{ query('varnames', '^incl_vars_(.*)$') }}&quot;
</code></pre>
gives
<pre class="lang-yaml prettyprint-override"><code>apps:
 - git_repo: https://github.com/philgyford/app2.git
 name: app2
 - git_repo: https://github.com/philgyford/app1.git
 name: app1
</code></pre>
You can convert the list to a dictionary if you want to
<pre class="lang-yaml prettyprint-override"><code> - set_fact:
 apps: &quot;{{ dict(_keys|zip(apps)) }}&quot;
 vars:
 _keys: &quot;{{ apps|map(attribute='name')|list }}&quot;

I've used this:
<pre><code>- name: Load data
 run_once: true
 set_fact:
 my_data: &quot;{{ my_data|default([]) + [lookup('file', item) | from_yaml] }}&quot;
 with_fileglob: &quot;../data/*.yml&quot; # relative to this file
</code></pre>

In Ansible, in a role, I have vars files like this:

<pre><code>vars/
 app1.yml
 app2.yml
</code></pre>

Each file contains vars specific to an app/website like this:

<pre><code>name: app1
git_repo: https://github.com/philgyford/app1.git
# ...
</code></pre>

Ideally, without the task knowing in advance which apps have variable files, I'd like to end up with an array called <code>apps</code> like this:

<pre><code>apps:
 - name: app1
 git_repo: https://github.com/philgyford/app1.git
 # ...
 - name: app2
 git_repo: https://github.com/philgyford/app2.git
 # ...
</code></pre>

ie, that combines the variables from the files into one.

I know I can load all the variable files like this:

<pre><code>- name: Load var files
 with_fileglob:
 - ../vars/*.yml
 include_vars: '{{ item }}'
</code></pre>

But given each file has identical variable names, it will overwrite each previous set of variables. I can't see a way to load the variables and put them into an <code>apps</code> array.

I'm open to rearranging things slightly if it's the only way to make something like this possible.

In Ansible, how to combine variables from separate files into one array?
