最近刚开始使用 Ansible，我遇到了一个问题。在我的 YAML 结构之一中，我定义了如下内容：

---
# file: main.yml
#
# Jenkins variables for installation and configuration

jenkins:
  debian:
    # Debian repository containing Jenkins and the associated key for accessing the repository
    repo: 'deb http://pkg.jenkins-ci.org/debian binary/'
    repo_key: 'http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key'

    # Dependencies needed for Jenkins to run properly
    dependencies:
      - 'openjdk-7-jdk'
      - 'git-core'
      - 'curl'

  port: 8080

  # Installation directory
  home: '/opt/jenkins'

  # Path to the location of the main Jenkins-cli binary
  bin_path: '{{jenkins.home}}/jenkins-cli.jar'

  # Path to the location of the Jenkins updates file
  updates_path: '{{jenkins.home}}/updates_jenkins.json'

Ansible 在特定任务中给了我这样的错误：

“在模板字符串中检测到递归循环：{{jenkins.home}}/updates_jenkins.json”

我已将其缩小到问题在于 bin_path 和 updates_path 都指的是“家”这一事实。有没有解决的办法？我需要多次定义“/opt/jenkins”，这有点糟糕。

据我所知，这是 jinja2 变量的限制。它与旧的 ${} 一起使用，并且从 1.4 开始就中断了。我不确定他们是否在 1.5 中修复了这个问题。

我的临时解决方案是从“詹金斯”搬家

这应该这样做：

bin_path: "{{ jenkins['home'] }}/jenkins-cli.jar"
