有没有办法覆盖定义为ansible星系角色的模板? [英] Is there a way to override a template defined into an ansible galaxy role?

问题描述

我正在尝试使用ansible设置服务器，并且我想使用此星系角色.

I'm trying to set up a server with ansible and I'd like to use this galaxy role.

它定义了一个模板想自定义，但我不知道如何.

It defines a template that I'd like to customize, but I don't know how.

现在，我在 requirements.yml 中定义了该角色，并使用以下命令进行了安装:

Right now I defined the role into requirements.yml and I installed it using:

ansible-galaxy install -r requirements.yml

将角色安装在我的系统上的某个地方.

which installed the role somewhere on my system.

我尝试通过将文件夹树重新创建到存储剧本的存储库中来进行尝试:

I tried by recreating the folder tree into my repository where I store my playbooks:

roles
  |- ansible-role-passenger
     |- templates
        |- passenger.j2

但是它不起作用.当我运行剧本时，ansible从星系角色内部使用 passenger.j2 文件.

but it does not work. When I run my playbook, ansible uses the passenger.j2 file from inside the galaxy role.

我想我可以在github上派出银河角色，然后按照我的需要编辑文件 passenger.j2 ，但是我不知道这是否是一种更好"的方法它:)

I think I can fork the galaxy role on github and just edit the file passenger.j2 like I want, but I don't know if this is there is a "better" way to do it :)

推荐答案

很遗憾，您的发现是正确的.除非角色的作者将其实现为功能，否则从调用的剧本中覆盖角色中的硬编码模板是完全不可能的.请注意，对于 files 目录中的简单文件也是如此.

Your findings are unfortunately true. Overriding a hardcoded template in a role from a calling playbook is merely impossible unless the role's author implemented that as a feature. Note that this is also true for simple files in the files directory.

到目前为止，我发现的最好方法是:鉴于角色包含 templates/passenger.j2 中的默认模板，请在 default/main.yml 中添加一个变量例如 passenger_config_template:passenger.j2 并在角色中使用该var.然后，用户可以在其剧本/清单中覆盖该var，并为模板使用其他名称，该模板将以其他角色或直接在剧本级别的 templates 目录中获取.

The best way I have found so far: given that the role contains the default template in templates/passenger.j2, add a var in default/main.yml such as passenger_config_template: passenger.j2 and use that var in the role. The user can then override that var in its playbook/inventory and use a different name for the template which will be fetched in an other role or directly in a templates directory at playbook level.

You can have a look at a similar issue and an accepted PR I once made to @geerlingguy on his ansible-role-gitlab. He might consider doing the same thing on his passenger role (or might accept your PR if you propose one).
