Question

我有一本Ansible剧本，用于创建Linode服务器。我遇到的问题是我的剧本无法确定新服务器何时启动。我正在使用Ansible 2.8.4。我的剧本如下：

---
hosts: 127.0.0.1
gather_facts: False

- name: create server
  linode_v4:
    label: "{{ host_name }}_{{ 100 | random }}"
    access_token: "{{ linode_api4_key }}"
    type: "{{ plan_1GB }}"
    region: "{{ region_us_central }}"
    image: "{{ image_debian_10 }}"
    root_pass: "{{ linode_root_password }}"
    authorized_keys: "{{ my_ssh_public_key }}"
    tags: "inventory.ini"
    state: present
  register: linode

- name: save new server's ip address to a fact
  set_fact: ip_addr={{ linode.instance.ipv4 }}
  tags: always

- debug:
    var: ip_addr

- name: wait until new server is up and listening on port 22
  wait_for:
    host: "{{ ip_addr }}"
    port: 22
    delay: 2
    timeout: 600
    state: started
    msg: "Server port is not listening"
  tags: always

我也这样尝试过：

- name: wait until new server is up
  local_action:
    module: wait_for
    state: started
    host: "{{ ip_addr }}"
    port: 22
    delay: 1
    timeout: 100

我尝试使用wait_for以及通过local_action来执行此操作，但是没有人起作用。剧本永远不会从等待任务中返回。我在剧本运行时监视我的Linode仪表板，我可以看到通过“ ip_addr”输入任务的IP地址是正确的，并且仪表板还可以在服务器启动时向我显示。我在做什么错了？

Answer 1

我通过注册操作结果并重试直到结果没有失败，解决了超时的类似问题。您可以配置重试之间的延迟和最大重试次数：

另外，我注意到您在游戏中没有包含状态，这可能会引起问题。

Answer 2

您可以尝试一下。

- name: Check if host is accessible
  wait_for: host=<host to check> port=80 timeout=3
  register: host_accessible
  failed_when: False

- include: next_task_you_want.yml
  when: host_accessible.state is defined and host_accessible.state == "started"
