How to refer to list during with_dict loop - loops

Question

I am trying to build playbook that dynamically queries Windows' registry to detect installed instances of SQL Server (or anything else), its version, location, etc. and do X action for every instance. This works ok if only one SQL instance is installed but I am not sure how to achieve this in multi-instance environment as I am mixing dicts and list and I am not sure how to solve this..
As a simple example playbook below detects installed SQL instances based on reg keys and checks version of SQL for each instance. I would like to out the info on per instance basis (or even better put this into dict variable so I can use it later and add more details based on other reg keys).
Problem is that some of the returned data is a list and I am not sure how to add it to the loop (or add it to dict where key is the instance for example).
Code:
- name: 'Go to Windows registry and check if any SQL instance is installed - using win_reg_stat module'
win_reg_stat:
path: HKLM:\SOFTWARE\Microsoft\Microsoft SQL Server\Instance Names\SQL
register: reg_InstalledInstances
- name: 'Go to Windows registry and for each installed instance get its version number'
win_reg_stat:
path: HKLM:\SOFTWARE\Microsoft\Microsoft SQL Server\{{item.value.raw_value}}\MSSQLServer\CurrentVersion
name: CurrentVersion
with_dict: '{{reg_InstalledInstances.properties}}'
register: reg_CurrentVersion
- debug:
msg:
- '{{reg_CurrentVersion}}'
- name: 'Show all the details'
debug:
msg:
- 'Hostname: {{inventory_hostname}}'
- 'SQL Instance: {{item.key}}'
- 'SQL Instance in Registry: {{item.value.raw_value}}'
#- 'CurrentVersion: {{reg_CurrentVersion.results.raw_value}}'
with_dict: '{{reg_InstalledInstances.properties}}'
- name:
debug:
msg:
- '{{reg_CurrentVersion}}'
Problem:
I am not sure how to refer reg_CurrentVersion into the loop - in the loop (i tried {{reg_CurrentVersion.results.item.raw_value}} as well):
...
- 'CurrentVersion: {{reg_CurrentVersion.results.raw_value}}'
with_dict: '{{reg_InstalledInstances.properties}}'
results in:
the task includes an option with an undefined variable. The error was: 'list object' has no attribute 'raw_value'
reg_CurrentVersion on its own works fine and looks like this:
ok: [gbltcdevcmdr01] => {
"msg": [
{
"changed": false,
"msg": "All items completed",
"results": [
{
"ansible_loop_var": "item",
"changed": false,
"exists": true,
"failed": false,
"item": {
"key": "SQL2014",
"value": {
"raw_value": "MSSQL12.SQL2014",
"type": "REG_SZ",
"value": "MSSQL12.SQL2014"
}
},
"raw_value": "12.0.6024.0",
"type": "REG_SZ",
"value": "12.0.6024.0"
},
{
"ansible_loop_var": "item",

"failed": false,
"item": {
"key": "SQL2016",
"value": {
"raw_value": "MSSQL13.SQL2016",
"type": "REG_SZ",
"value": "MSSQL13.SQL2016"
}
},
"raw_value": "13.2.5026.0",
"type": "REG_SZ",
"value": "13.2.5026.0"
},
{
"ansible_loop_var": "item",
"changed": false,
"exists": true,
"failed": false,
"item": {
"key": "MSSQLSERVER",
"value": {
"raw_value": "MSSQL11.MSSQLSERVER",
"type": "REG_SZ",
"value": "MSSQL11.MSSQLSERVER"
}
},
"raw_value": "11.0.7001.0",
"type": "REG_SZ",
"value": "11.0.7001.0"
},
{
"ansible_loop_var": "item",
"changed": false,
"exists": true,
"failed": false,
"item": {
"key": "SQL2017",
"value": {
"raw_value": "MSSQL14.SQL2017",
"type": "REG_SZ",
"value": "MSSQL14.SQL2017"
}
},
"raw_value": "14.0.1000.169",
"type": "REG_SZ",
"value": "14.0.1000.169"
}
]
}
]
}
EDIT:
at the moment if I run the initial code:
...
- name: 'Show all the details'
debug:
msg:
- 'Hostname: {{inventory_hostname}}'
- 'SQL Instance: {{item.key}}'
- 'SQL Instance in Registry: {{item.value.raw_value}}'
#- 'CurrentVersion: {{reg_CurrentVersion.results.raw_value}}'
with_dict: '{{reg_InstalledInstances.properties}}'
I got this:
ok: [testhost] => (item={'key': 'SQL2014', 'value': {'raw_value': 'MSSQL12.SQL2014', 'value': 'MSSQL12.SQL2014', 'type': 'REG_SZ'}}) => {
"msg": [
"Hostname: testhost",
"SQL Instance: SQL2014",
"SQL Instance in Registry: MSSQL12.SQL2014"
]
}
ok: [testhost] => (item={'key': 'SQL2016', 'value': {'raw_value': 'MSSQL13.SQL2016', 'value': 'MSSQL13.SQL2016', 'type': 'REG_SZ'}}) => {
"msg": [
"Hostname: testhost",
"SQL Instance: SQL2016",
"SQL Instance in Registry: MSSQL13.SQL2016"
]
}
ok: [testhost] => (item={'key': 'MSSQLSERVER', 'value': {'raw_value': 'MSSQL11.MSSQLSERVER', 'value': 'MSSQL11.MSSQLSERVER', 'type': 'REG_SZ'}}) => {
"msg": [
"Hostname: testhost",
"SQL Instance: MSSQLSERVER",
"SQL Instance in Registry: MSSQL11.MSSQLSERVER"
]
}
ok: [testhost] => (item={'key': 'SQL2017', 'value': {'raw_value': 'MSSQL14.SQL2017', 'value': 'MSSQL14.SQL2017', 'type': 'REG_SZ'}}) => {
"msg": [
"Hostname: testhost",
"SQL Instance: SQL2017",
"SQL Instance in Registry: MSSQL14.SQL2017"
]
}
I would like to simply add reg_CurrentVersion.results.raw_value as an extra line for each instance. Something like below:
ok: [testhost] => (item={'key': 'SQL2014', 'value': {'raw_value': 'MSSQL12.SQL2014', 'value': 'MSSQL12.SQL2014', 'type': 'REG_SZ'}}) => {
"msg": [
"Hostname: testhost",
"SQL Instance: SQL2014",
"SQL Instance in Registry: MSSQL12.SQL2014"
"CurrentVersion: 12.0.6024.0"
]
}
ok: [testhost] => (item={'key': 'SQL2016', 'value': {'raw_value': 'MSSQL13.SQL2016', 'value': 'MSSQL13.SQL2016', 'type': 'REG_SZ'}}) => {
"msg": [
"Hostname: testhost",
"SQL Instance: SQL2016",
"SQL Instance in Registry: MSSQL13.SQL2016"
"CurrentVersion: 13.2.5026.0"
]
}
ok: [testhost] => (item={'key': 'MSSQLSERVER', 'value': {'raw_value': 'MSSQL11.MSSQLSERVER', 'value': 'MSSQL11.MSSQLSERVER', 'type': 'REG_SZ'}}) => {
"msg": [
"Hostname: testhost",
"SQL Instance: MSSQLSERVER",
"SQL Instance in Registry: MSSQL11.MSSQLSERVER"
"CurrentVersion: 11.0.7001.0"
]
}
ok: [testhost] => (item={'key': 'SQL2017', 'value': {'raw_value': 'MSSQL14.SQL2017', 'value': 'MSSQL14.SQL2017', 'type': 'REG_SZ'}}) => {
"msg": [
"Hostname: testhost",
"SQL Instance: SQL2017",
"SQL Instance in Registry: MSSQL14.SQL2017"
"CurrentVersion: 14.0.1000.169"
]
}
PS. Is there a way to build dict and append new values to it later on?

Q: "Is there a way to build a dictionary and append new values to it later on?"
A: Yes. It's possible. Let's create the dictionary with the data
- set_fact:
mylist: "{{ reg_CurrentVersion.results|
json_query('[].{instance: item.key,
registry: item.value.raw_value,
version: raw_value}') }}"
- debug:
var: mylist
gives
"mylist": [
{
"instance": "SQL2014",
"registry": "MSSQL12.SQL2014",
"version": "12.0.6024.0"
},
{
"instance": "SQL2016",
"registry": "MSSQL13.SQL2016",
"version": "13.2.5026.0"
},
{
"instance": "MSSQLSERVER",
"registry": "MSSQL11.MSSQLSERVER",
"version": "11.0.7001.0"
},
{
"instance": "SQL2017",
"registry": "MSSQL14.SQL2017",
"version": "14.0.1000.169"
}
]
Append hostname to each dictionary
- set_fact:
mylist2: "{{ mylist2|default([]) +
[item|combine({'hostname': inventory_hostname})] }}"
loop: "{{ mylist }}"
- debug:
var: mylist2
gives
"mylist2": [
{
"hostname": "localhost",
"instance": "SQL2014",
"registry": "MSSQL12.SQL2014",
"version": "12.0.6024.0"
},
{
"hostname": "localhost",
"instance": "SQL2016",
"registry": "MSSQL13.SQL2016",
"version": "13.2.5026.0"
},
{
"hostname": "localhost",
"instance": "MSSQLSERVER",
"registry": "MSSQL11.MSSQLSERVER",
"version": "11.0.7001.0"
},
{
"hostname": "localhost",
"instance": "SQL2017",
"registry": "MSSQL14.SQL2017",
"version": "14.0.1000.169"
}
]
