Ansible combine two results based on the key - ansible

Question

If someone can suggest a resource to self educate, would be much appreciated. At the moment I am learning by examples based on what works. Sorry if the terminology is incorrect
I have two results in json format (dictionary?) from the commands sent to Netscaler API:
Result1 lists certificate information:
{
"errorcode": 0,
"message": "Done",
"severity": "NONE",
"sslcertkey": [
{
"certkey": "certkey1.pair",
"daystoexpiration": 0,
"status": "Expired",
"subject": "easdm.test.com"
},
{
"certkey": "certkey2.pair",
"daystoexpiration": 0,
"status": "Expired",
"subject": " CN=timer.test.com"
},
Result2 lists which certificate is bound to a virtual server:
{
"errorcode": 0,
"message": "Done",
"severity": "NONE",
"sslcertkey_sslvserver_binding": [
{
"certkey": "certkey1.pair",
"data": "1",
"servername": "easdm_gslb_btfin_pri_lb_vs",
"stateflag": "2",
"version": 1
},
{
"certkey": "certkey2.pair",
"data": "2",
"servername": "timer_gslb_btfin_pri_lb_vs",
"stateflag": "2",
"version": 1
},
I want to combine two results into Result3, so that it will combine info from Result1 with Result2 if "certkey" is matching between the results:
{
"certkey": "certkey1.pair",
"daystoexpiration": 0,
"status": "Expired",
"subject": "easdm.test.com",
"servername": "easdm_gslb_btfin_pri_lb_vs"
},
{
"certkey": "certkey2.pair",
"daystoexpiration": 0,
"status": "Expired",
"subject": " CN=timer.test.com",
"servername": "timer_gslb_btfin_pri_lb_vs"
},
There are 100's of entries in each result and some results in Result1 will not have a match in Result2 as cert is not used anywhere.
I tried using just a simple
- debug:
msg: '{{ result.json.sslcertkey | combine(result2.json.sslcertkey_sslvserver_binding, recursive=True) }}'
but it seem to only show the last match and not all of the matches.

Answer 1

Use filter community.general.lists_mergeby
result3: "{{ result1.sslcertkey|
community.general.lists_mergeby(result2.sslcertkey_sslvserver_binding,
'certkey') }}"
gives
result3:
- certkey: certkey1.pair
data: '1'
daystoexpiration: 0
servername: easdm_gslb_btfin_pri_lb_vs
stateflag: '2'
status: Expired
subject: easdm.test.com
version: 1
- certkey: certkey2.pair
data: '2'
daystoexpiration: 0
servername: timer_gslb_btfin_pri_lb_vs
stateflag: '2'
status: Expired
subject: ' CN=timer.test.com'
version: 1
