YAML列表筛选

Question

有人能在以下方面帮助我吗：

任一

ok: [localhost] => {
"tag_info": {
"changed": false,
"msg": "All items completed",
"results": [
{"vm_list": [ "NSY6TFSANSBL01"]},
]

OR
ok: [localhost] => {
"tag_info": {
"changed": false,
"msg": "All items completed",
"results": [
{"vm_list": [ "NSY6TFSANSBL01"]},
{"vm_list": [ "NSY6TFSANSBL01,NSY6TFSANSBL02"]},
{"vm_list": [ "NSY6TFSANSBL01,NSY6TFSANSBL02,NSY6TFSANSBL03"]},
]
Intersection of N lists works with the code
- set_fact:
final_list: "{{ final_list|
default(tag_info.results.0.vm_list)|
intersect(tag_info.results[item].vm_list) }}"
loop: "{{ range(1, tag_info.results|length, 1)|list }}"

当只有一个vm_list对象时，我希望final_list为｛"vm_list"：["NSY6TFSANSBL01"]｝，否则它应该是多个列表的交集。你能告诉我怎么写吗。

Answer 1

这样写

- set_fact:
final_list: "{{ (tag_info | json_query('results[*].vm_list')|flatten(levels=1)|unique if tag_info.results|length > 1) | default(tag_info.results.0.vm_list) }}"
loop: "{{ tag_info.results }}"
- debug:
var: final_list

假设：

每个问题中的所有vmlist对象都是数组中的单个字符串。

我假设不是这样，它实际上是一个字符串列表，如下所示，

ok: [localhost] => {
"tag_info": {
"changed": false,
"msg": "All items completed",
"results": [
{"vm_list": [ "NSY6TFSANSBL01"]},
]

OR
ok: [localhost] => {
"tag_info": {
"changed": false,
"msg": "All items completed",
"results": [
{"vm_list": [ "NSY6TFSANSBL01"]},
{"vm_list": [ "NSY6TFSANSBL01","NSY6TFSANSBL02"]},
{"vm_list": [ "NSY6TFSANSBL01","NSY6TFSANSBL02","NSY6TFSANSBL03"]},
]
