使用一些任务和另一个剧本创建剧本

Question

目前我正在寻找一种解决方案，我可以在其中创建一个变量，然后使用该变量导入 Playbook。

这是我的代码：

- name: test
  hosts: localhost
  vars:
    ansible_python_interpreter: /usr/bin/python3
    playbook1: server_provision
    playbook2: server_provision_oracle
  gather_facts: no
  tasks:
  - name: define Variable with when condition
    set_fact:
      server_provision: "{{ playbook1 }}"
    when: OS == "RHEL"

  - name: store variable to file
    copy:
      content: "server_provision: {{ server_provision }}"
      dest: /tmp/server_provision.yml
    when: OS == "RHEL"

  - name: define Variable with when condition
    set_fact:
      server_provision: "{{ playbook2 }}"
    when: OS == "Oracle"

  - name: store variable to file
    copy:
      content: "server_provision: {{ server_provision }}"
      dest: /tmp/server_provision.yml
    when: OS == "Oracle"


- name: test
  vars_files:
    - /tmp/server_provision.yml
  import_playbook: "{{ server_provision }}.yaml"

但是当我执行剧本时，我得到了错误，变量 server_provision 没有价值。

问题是我的 unimportet 剧本没有被执行，它从 importet 开始。

你有解决办法吗？

您可以使用 pre_tasks。 Pre Taks 在任务部分之前执行。 Ansible Docs

类似这样的：

---
  hosts: localhost
  vars:
    ansible_python_interpreter: /usr/bin/python3
    playbook1: server_provision
    playbook2: server_provision_oracle
  gather_facts: no

  vars_files:
    - /tmp/server_provision.yml

  pre_tasks:
  - name: define Variable with when condition
    set_fact:
      server_provision: "{{ playbook1 }}"
    when: OS == "RHEL"

  - name: store variable to file
    copy:
      content: "server_provision: {{ server_provision }}"
      dest: /tmp/server_provision.yml
    when: OS == "RHEL"

  - name: define Variable with when condition
    set_fact:
      server_provision: "{{ playbook2 }}"
    when: OS == "Oracle"

  - name: store variable to file
    copy:
      content: "server_provision: {{ server_provision }}"
      dest: /tmp/server_provision.yml
    when: OS == "Oracle"

  tasks:
    - name: test
      import_playbook: "{{ server_provision }}.yaml"
