让ansible等待ssh连接

Question

如何让ansible等待或重试ssh连接？我有一个ansible tsk，它运行govc将虚拟机上传到vcenter，但在那之后，我立即ssh到机器中运行如下命令：

  hosts: vcenter
  gather_facts: false
  tasks:
    - name: Download GOVC
      get_url:
        url: https://github.com/vmware/govmomi/releases/download/v0.20.0/govc_linux_amd64.gz
        dest: /home/gkeadmin/govc_linux_amd64.gz

但在我得到以下代码后立即执行：fatal: [139.178.66.91]: UNREACHABLE! => {"changed": false, "msg": "Failed to connect to the host via ssh: ssh: connect to host 1.2.3.4 port 22: Operation timed out", "unreachable": true}

我再次使用--retry命令重新运行它，然后它继续运行。在我可以通过ssh...how连接之前，似乎只需要一段时间，我需要等待ssh连接在ansible中建立吗？

Answer 1

ansible支持重试。希望这能对你有所帮助。

---
- name: test
  retries: 2
  hosts: <hosts_name>
  tasks:
    - name: task
      <module_name>:

Answer 2

您可以在攻略顶部添加一个部分来等待它，例如

---
- name: wait for ssh
  tasks:
  - wait_for:
      port: 22
      host: '{{ inventory_hostname }}'
    delegate_to: localhost
- name: my playbook
  hosts: vcenter
  gather_facts: false
  tasks:
   - name: Download GOVC
  [ ... etc ... ]
