# Dashboard

[Ansible Tower](https://www.ansible.com/tower)是企业级的Ansible web管理平台，提供了较为完善的观察Ansible任务运行的Dashboard。Tower允许控制访问帐号，以及分发SSH证书。可以通过图形界面管理`清单`文件或者从云进行同步。Tower提供了任务的日志，集成LDAP以及REST API。提供了方便和Jenkins集成的命令工具，和支持自动扩展拓扑的回调。

不过，Ansible Tower不是开源软件，对于10个节点免费，大规模应用场景需要购买Licence。

## Ansible Tower的开源替代

[semaphore](https://github.com/ansible-semaphore/semaphore)是Ansible Tower的基本功能的clone，提供了：

* 快速简单的WEB管理界面
* 通过websocket来输出任务信息
* 针对每个playbook来创建清单
* 针对特定主机运行playbook
* 多用户支持

## Ansible Tower和Foreman对比

[Foreman vs. Ansible Tower](https://www.upguard.com/articles/foreman-vs.-ansible-tower)比较了开源的服务器生命周期管理工具[Foreman](http://theforeman.org)和闭源的[Ansible Tower](https://www.ansible.com/tower)的使用场景。

> Foreman是一个非常成功的Puppet和Chef自动化管理平台，并且是得到社区活跃支持和持续开发的平台。

Foreman通过Smart Proxy架构来自动化集成配置管理平台Puppet/Chef，提供了REST API来扩展。Smart Proxy支持DHCP, DNS, TFTP 并默认支持Puppet和Chef连接。

Ansible目标是构建替代Puppet和Chef的轻量级自动化工具，所以其架构不同：使用Python编写，运行在SSH之上。Ansible Tower提供了实时的节点监控，显示当前运行的任务，以及存在问题的节点，这样可以快速检查问题。

> 从资料来看，对于Ansible开源项目，目前尚未有类似Foreman这样能够和Puppet/Chef完善结合的平台，对企业级运行Ansible来说，还是需要定制开发。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://huataihuang.gitbook.io/cloud-atlas-draft/devops/ansible/dashboard.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
