使用 Ansible 测试服务器是否可从主机访问并打开端口 [英] Test if a server is reachable from host and has port open with Ansible

问题描述

我想测试我配置的主机是否可以访问特定服务器并连接到特定 TCP 端口.如果它不能，剧本应该会失败.

I want to test if the host I am provisioning can reach a specific server and connect to a specific TCP port. If it can't the playbook should fail.

我该怎么做?

推荐答案

有 wait_for 模块.
要检查 target.host 是否可以访问 remote.host:8080:

There is wait_for module for this.
To check that target.host can access remote.host:8080:

- hosts: target.host
  tasks:
    - wait_for: host=remote.host port=8080 timeout=1
    - debug: msg=ok

文档中还有很多其他示例.

There are a lot of other examples in the documentation.
