Hi Team,
Greetings for the day!
I have a variables called ‘aggregates’ under vars which ontaints cluster1,cluster3,cluster2…etc and aggr1,aggr2,aggr3…etc list as mentioned below.
{
“aggregates”: [
[
“Cluster1”,
“aggr1”
],
[
“Cluster1”,
“aggr2”
],
[
“Cluster1”,
“aggr4”
],
[
“Cluster2”,
“aggr1”
],
[
“Cluster3”,
“aggr2”
]
]
}
Your ‘aggregates’ is a list of lists. For each aggregate list item, you have a two-element list where element [0] is cluster name and element [1] is aggregate name.
Loop through aggregates, and use item.0 for cluster and item.1 for hostname ?

Yes, I got it what I was looking for.
Thank you very much for your help Todd and Walter.
If you are defining aggregates (vs getting from some other task register var), there is another way you could construct your aggregates var.
aggregates:
{ cluster: “Cluster 1”, aggregate: “aggr1” }
{ cluster: “Cluster 1”, aggregate: “aggr2” }
{ cluster: “Cluster 1”, aggregate: “aggr4” }
{ cluster: “Cluster 2”, aggregate: “aggr1” }
{ cluster: “Cluster 3”, aggregate: “aggr2” }
This syntax makes it really easy to add more items and maintain proper syntax.
Your item.0 changes to item.cluster, and your item.1 change to item.aggregate.
name: Get info
na_ontap_rest_info:
<<: *login
gather_subset:
storage/volumes
parameters:
aggregates.name: “{{ item.cluster }}”
hostname: “{{ item.aggregate }}”
use_python_keys: true
register: vol_data
loop: “{{ aggregates }}”
no_log: false
debug: var=vol_data
This might be more description and easier for someone else to make the connection between your aggregates var and your loop references. The aggregates var is still a list. It is a list of JSON dictionary items.
Hi, All and Walter,
Thank you for good suggestions.
That’s a really good way to deal with it but there is something I should mention here to request help.
Actually below aggregates data coming from another set_task ( see below) which contains a list data.
vars:
aggregates:
aggregates data coming below set_fact.
Looking for:
As above mentioned set_fact giving data into list into lists, Can we make aggregates data into dict structure as mentioned below from same set_fact ?
aggregates:
{ cluster: “Cluster 1”, aggregate: “aggr1” }
{ cluster: “Cluster 1”, aggregate: “aggr2” }
{ cluster: “Cluster 1”, aggregate: “aggr4” }
{ cluster: “Cluster 2”, aggregate: “aggr1” }
{ cluster: “Cluster 3”, aggregate: “aggr2” }
Thank you for your time and helping out.
No problem.
set_fact:
json_list: “{{ aggregates2 | map(‘zip’,[‘cluster’,‘aggregate’]) | map(‘map’,‘reverse’) | map(‘community.general.dict’) }}”
produces
“json_list”: [
{
“aggregate”: “aggr1”,
“cluster”: “Cluster 1”
},
{
“aggregate”: “aggr2”,
“cluster”: “Cluster 1”
},
{
“aggregate”: “aggr4”,
“cluster”: “Cluster 1”
},
{
“aggregate”: “aggr1”,
“cluster”: “Cluster 2”
},
{
“aggregate”: “aggr2”,
“cluster”: “Cluster 3”
}
]

Hi,
Is there any version dependance to use community.general.dict? my current Ansible version 2.9.13.
When i use
output:
ok: [localhost] => {
“json_list”: “<generator object sync_do_map at 0x7f47f2a99fc0>”
When i use:
Output:
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: jinja2.exceptions.TemplateRuntimeError: No filter named ‘community.general.dict’.
fatal: [localhost]: FAILED! => {
“changed”: false
}
Absent community.general.dict you can do it in two steps:
set_fact:
json_list: “{{ aggregates2 | map(‘zip’,[‘cluster’,‘aggregate’]) | map(‘map’,‘reverse’) }}”
loop: “{{ aggregates2 }}”
set_fact:
new_list: “{{ (new_list | default()) + [ { item.0.0: item.0.1, item.1.0: item.1.1 } ] }}”
loop: “{{ json_list }}”

Hi Walter,
Sorry for the trouble. I got still some error

The same playbook also giving issue from end. May be i will look into in deep if any version dependance.
the output i got for you provided playbook:

You probably need to upgrade your ansible.
Walter
Yes guess so, Thanking you once again.
