在 Ansible 中如何在遍历剧本中的数组时执行角色
In Ansible how to execute a role while looping over an array in the playbook
我想遍历数组并将每个数组元素值传递给 playbook 中的角色,但它在 ansible 中不起作用,有人能帮忙吗

#play book
- name: create config for instance
hosts: all
vars:
LIST: [Asia, Americas, Artic, Antartic ,Oceania,Europe,Africa]
connection: local
roles:
- role: create_config
debug:
msg : "{{ item }}"
vars:
VENUE: "{{ item }}"
with_items:
- "{{ LIST }}"
## Role
- name: create directory structure
file:
path: "{{item}}"
state: directory
mode: 0755
with_items:
- "{{dest_folder}}/{{instance_name}}/{{VENUE}}"
我低于错误
ansible-playbook -i inventory/AlgoTest_SP create_pkg_1.yml
PLAY [create config for instance] **************************************************************************************************************************************
TASK [Gathering Facts] ****************************************************************************************************************************************************
ok: [localhost]
TASK [create_config : create directory structure] *******************************************************************************************************************
fatal: [localhost]: FAILED! => {"msg": "{{ item }}: 'item' is undefined"}
PLAY RECAP ****************************************************************************************************************************************************************
localhost : ok=1 changed=0 unreachable=0 failed=1 skipped=0 rescued=0 ignored=0
为了能够循环角色,您需要 include_role
任务,如:
- name: create config for instance
hosts: localhost
vars:
LIST: [Asia, Americas, Artic, Antartic ,Oceania,Europe,Africa]
tasks:
- include_role:
name: create_config
vars:
VENUE: "{{ item }}"
with_items:
- "{{LIST}}"
cat roles/create_config/tasks/main.yml
- debug:
msg: "{{VENUE}}"
- name: create directory structure
file:
path: "{{item}}"
state: directory
mode: 0755
with_items:
- "{{inventory_hostname}}/{{VENUE}}"
导致:
$ ansible-playbook 69045121.yml
PLAY [create config for instance] ********************************************************************************************************************************************************************************************************************************************************************************************
TASK [Gathering Facts] *******************************************************************************************************************************************************************************************************************************************************************************************************
ok: [localhost]
TASK [include_role : create_config] ******************************************************************************************************************************************************************************************************************************************************************************************
TASK [create_config : debug] *************************************************************************************************************************************************************************************************************************************************************************************************
ok: [localhost] => {
"msg": "Asia"
}
TASK [create_config : create directory structure] ****************************************************************************************************************************************************************************************************************************************************************************
changed: [localhost] => (item=localhost/Asia)
TASK [create_config : debug] *************************************************************************************************************************************************************************************************************************************************************************************************
ok: [localhost] => {
"msg": "Americas"
}
[...] and so on
最后一点,您可以而且应该以不同的方式处理这个问题。此外,您在外部(剧本)和内部(角色)with_items 的 item
变量名中存在冲突 with_items,您可以使用 loop_var
设置不同的循环变量名。
