Question

我正在使用ansible剧本在数字海洋中创建Droplet，并希望在启动时使用ansible对其进行配置。 Droplet创建成功，但是当我尝试在启动时对其进行配置时，它给了python依赖性问题。我知道它，但是现在我很困惑如何在启动时或即时安装它？以下是我的烦人剧本：

---
- hosts: localhost
  tasks:
  - name: Create new DO Droplet
    digital_ocean:
     state: present
     command: droplet
     name: ansibletest
     api_token: xyz123
     size_id: '1gb'
     region_id: ams3
     image_id: '39739486'
     ssh_key_ids: '23625890'
    register: my_droplet
  - name: print info about my_droplet
    local_action:
      module:  debug
         msg= "ID is {{ my_droplet.droplet.id }} IP is {{ my_droplet.droplet.ip_address }}"
  - name: Add new droplet to host group
    local_action: add_host hostname={{ my_droplet.droplet.ip_address }} groupname=launched
  - name: Wait for SSH to come up
    local_action: wait_for host={{ my_droplet.droplet.ip_address }} port=22 delay=60 timeout=320 state=started
- hosts: launched
  become: true
  gather_facts: True
  tasks:
  - name: installing redis server 
    apt: name=redis-server state=latest

下面是我得到的错误，它与远程客户端上的python依赖关系有关。

fatal: [188.26.76.45]: FAILED! => {"changed": false, "module_stderr": "Shared connection to 188.166.71.116 closed.\r\n", "module_stdout": "/bin/sh: 1: /usr/bin/python: not found\r\n", "msg": "MODULE FAILURE", "rc": 127}

我没有在AWS中解决此问题，因为EC2实例具有python2.7。您能否帮我解决此问题，以便我可以在启动时使用Ansible配置数字海洋飞沫。任何指导将不胜感激。

我已经使用以下命令运行了剧本： ansible-playbookdrop.yml-密钥文件“ /etc/ansible/tek.pem”

谢谢。

您可以使用raw:模块配置实例，该模块仅需要ssh访问。

您可以在kubespray bootstrap role中看到这种情况的示例，但是tl; dr是：

- hosts: launched
  gather_facts: no
  become: yes
  tasks:
  - raw: |
     set -e
     # but you are responsible for your own idempotent behavior
     if [ -x /usr/bin/python ]; then exit 0; fi
     export DEBIAN_FRONTEND=noninteractive
     apt-get update
     apt-get install -y python
  # now, in theory, you can resume using ansible modules
  # and can do the equivalent of "gather_facts: yes"
  - setup:
  - # etc etc
