如何将动态变量传递给Ansible角色

Question

对于我们的每个服务器（web和perls），我们为每种类型的服务器提供不同的挂载点。所以对于Web服务器，我想使用＆＃34; web_mounts＆＃34;的条目。和perls将是＆＃34; perl_mounts。＆＃34;

如果我硬编码＆＃34; web_mounts＆＃34;进入＆＃34; with_items，＆＃34;它工作正常。否则，它告诉我＆＃34; nfs_group＆＃34;未定义。

import React from 'react';
import CheckpointView from './CheckpointView';

class OneCheckpointData extends React.Component {
  constructor(props, context) {
    super(props, context);

    this.state = {
      checkpoint: null,
      user: null
    };

  }

  componentWillMount() {
    this.loadCheckpoint();
    this.context.getUser((data) => this.setState({ user: data }));
  }

  loadCheckpoint() {
    $.ajax({
      url: `/api/v1/modules/three/cp/${this.props.params.cp_id}`,
      method: 'GET',
    }).done((data) => {
      this.setState({ checkpoint: data });
    });
  }

  render() {
    return this.state.checkpoint ? <CheckpointView user={this.state.user} checkpoint={this.state.checkpoint} /> : null;
  }
}

OneCheckpointData.displayName = OneCheckpointData;

OneCheckpointData.contextTypes = {
  getUser: React.PropTypes.func.isRequired
};

export default OneCheckpointData;

将你的坐骑分组在这样的字典中：

---
mounts:
  web_mounts:
    - { source: "nfs.local:/nfs/web1", dest: "/web1", opts: "rw,noatime" }
    - { source: "nfs.local:/nfs/web2", dest: "/web2", opts: "rw,noatime" }
  perl_mounts:
    - { source: "nfs.local:/nfs/perl1", dest: "/perl1", opts: "rw,noatime" }
    - { source: "nfs.local:/nfs/perl2", dest: "/perl2", opts: "rw,noatime" }

并访问这样的dict元素：

- name: Create fstab entries
  mount: fstab=nfs state=present opts="{{ item.opts }}" src="{{ item.source }}" name="{{ item.dest }}"
  with_items: "{{ mounts[nfs_group] }}"

至于＆＃34; nfs_group未定义＆＃34; 错误，请检查您是否正确调用了角色 - 您的角色名称是＆＃34; nfs_mounts＆＃34;你的顶级剧本适用于角色＆＃34;网站＆＃34;。
