如何自动安装 Ansible Galaxy 角色? [英] How to automatically install Ansible Galaxy roles?

问题描述

我所有的 Ansible 剧本/角色都已签入我的 git 存储库.

All my Ansible playbooks/roles are checked in to my git repo.

但是，对于 Ansible Galaxy 角色，我总是必须在我想从中运行 Ansible 的每台机器上明确地一个一个地下载它们.

However, for Ansible Galaxy roles I always have to explicitly download them one by one on every machine I want to run Ansible from.

在 Ansible 抱怨运行时缺少角色之前，甚至很难提前确切知道需要哪些 Ansible Galaxy 角色.

It's even tough to know in advance exactly which Ansible Galaxy roles are needed until Ansible complains about a missing role at runtime.

应该如何管理 Ansible Galaxy 角色依赖项?我想让它们与我的其他 ansible 代码一起检入我的 git repo，或者在我在新机器上运行 Ansible 时自动识别和下载它们.

How is one supposed to manage the Ansible Galaxy role dependencies? I would like to either have them checked into my git repo along with the rest of my ansible code or have them automatically be identified and downloaded when I run Ansible on a new machine.

推荐答案

对于此用例，您应该使用 requirements.yml 文件.使用各种安装方法中的任何一种描述您需要的角色:

You should use a requirements.yml file for this use-case. Describe the roles you require, using any of a variety of install methods:

# Install a role from the Ansible Galaxy
- src: dfarrell07.opendaylight

# Install a role from GitHub
- name: opendaylight
  src: https://github.com/dfarrell07/ansible-opendaylight

# Install a role from a specific git branch
- name: opendaylight
  src: https://github.com/dfarrell07/ansible-opendaylight
  version: origin/master

# Install a role at a specific tag from GitHub
- name: opendaylight
  src: https://github.com/dfarrell07/ansible-opendaylight
  version: 1.0.0

# Install a role at a specific commit from GitHub
- name: opendaylight
  src: https://github.com/dfarrell07/ansible-opendaylight
  version: <commit hash>

然后安装它们:

ansible-galaxy install -r requirements.yml

这是一个工作示例(使用 Ansible 作为 Vagrant 配置器安装 OpenDaylight).有关详细信息，请参阅相关 Ansible 文档.

Here's a working example (installing OpenDaylight using Ansible as a Vagrant provisioner). See the relevant Ansible docs for more info.
