I'm trying to filter a list of attributes from the below output. selection and value attributes need to be listed.
Output:
ok: [192.0.0.3] => {
"allow": "GET, PUT",
"attempts": 1,
"invocation": {
}
},
"json": {
"body": [
{
"selection": "fqdn",
"value": "airbus3.org"
},
{
"selection": "fqdn",
"value": "airbus4.org"
}
],
"key": "ntp_servers",
"meta": {
"transaction": "/api/transaction"
}
},
}
I'm trying to use the below task to filter but it's not working.
- set_fact:
ntp_details: "{{ item.selection }}"
with_items: "{{ reg_ntp.json.body | json_query('[*]') }}"
Please advise..
For example
- set_fact:
ntp_details: "{{ reg_ntp.json.body|json_query('[].selection') }}"
should give
ntp_details:
- fqdn
- fqdn

Below is my JSON file:

}

I need to get log list's name and file-name like below using ansible code.
myserv1_log: "/web/bea_logs/domains/mydom/myserv1/myserv1.log"
myserv2_log: "/web/bea_logs/domains/mydom/myserv2/myserv2.log"
There are two challenges that i m facing.
server may not always be the 3rd key of domain array.
log array may not alway be a key for all server arrays and thus should not be printed. For example. server name AdminServer does not have any log list while myserv1 & myserv2 do have.
I need an ansible code to print the desired for the dynamically changing json.
Note: server will always be a key in the domain array
I'm posting with reference to my similar query here: unable to ideally parse a json file in ansible
Kindly suggest.
you just test if both keys exist:
- hosts: localhost
gather_facts: no
vars:
json: "{{ lookup('file', './file.json') | from_json }}"
tasks:
- name: display
debug:
msg: "name: {{ servername }} --> filename: {{ filename }}"
loop: "{{ json[1].domain }}"
vars:
servername: "{{ item.server.0.name }}_log"
filename: "{{ item['server'][2]['log'][1]['file-name'] }}"
when: item.server is defined and item.server.2.log is defined
result:
TASK [display]
skipping: [localhost] => (item={'name': 'USWL1212MRSHM01'})
skipping: [localhost] => (item={'domain-version': '12.2.1.3.0'})
skipping: [localhost] => (item={'server': [{'name': 'AdminServer'}, {'ssl': {'name': 'AdminServer'}}, {'listen-port': '12400'}, {'listen-address': 'myhost1'}]})
ok: [localhost] => (item={'server': [{'name': 'myserv1'}, {'ssl': {'name': 'myserv1'}}, {'log': [{'name': 'myserv1'}, {'file-name': '/web/bea_logs/domains/mydom/myserv1/myserv1.log'}]}]}) => {
"msg": "name: myserv1_log --> filename: /web/bea_logs/domains/mydom/myserv1/myserv1.log"
}
ok: [localhost] => (item={'server': [{'name': 'myserv2'}, {'ssl': {'name': 'myserv2'}}, {'log': [{'name': 'myserv2'}, {'file-name': '/web/bea_logs/domains/mydom/myserv2/myserv2.log'}]}]}) => {
"msg": "name: myserv2_log --> filename: /web/bea_logs/domains/mydom/myserv2/myserv2.log"
}
As you can see, when the condition is not true, the action is skipped...
you could simplify by testing only key log, because in your case, keylog is always linked to key server
when: item.server.2.log is defined

Please see JSON results above. I hope that someone can help me. I should take two fields, an item and datacenter_info.name
I can get values separate. I don't know how to create a dictionary because I have 2 items and 3 datacenter_info.name
enter - name: Set all_items
set_fact:
all_items: "{{ vmware_dc_info.results | flatten | map(attribute='item) | flatten }}"
- name: debug all_items
debug:
var: all_items
{
"all_items": [
"vc-001",
"vc-002"
]
- name: Set all dc
set_fact:
all_dc: "{{ vmware_dc_info.results | flatten | map(attribute='datacenter_info') | flatten | map(attribute='name') | flatten }}"
- name: debug all_dc
debug:
var: all_dc
"all_dc": [
"dc-1",
"dc-2",
"dc-3"
Dictionary should looks like below
vc-001: dc-1
vc-002: dc-2
vc-002: dc-3
Is it possible? What do you think?
Resolved with code below
- name: Set fact
set_fact:
dc_list: "{{ dc_list | default([]) + [{'vcenter': item[0].item, 'dc': item[1].name}] }}"
with_subelements:
- "{{ vmware_dc_info.results }}"
- datacenter_info
loop_control:
label: "{{ item[0].item }}"
- name: Debug
debug:
var: dc_list
For example
- set_fact:
hostnames: "{{ hostnames|d({})|combine({item: names}) }}"
loop: "{{ vmware_dc.results|map(attribute='item')|list }}"
vars:
_item: "{{ vmware_dc.results|selectattr('item', '==', item) }}"
names: "{{ _item.0.datacenter_info|map(attribute='name')|list }}"
gives you the expected result
hostnames:
vc-001:
- dc-1
vc-002:
- dc-2
- dc-3
can somebody please help me with this json parse?

and I am trying this playbook
tasks:

register: atc_AS3_status
no_log: true
- name : Parse json 1

vars:
query_result: "\"ACS-AS3\".ACS"
#query_result1: "\"ACS-AS3\".ACS.*.virtualAddresses"
register: atc_AS3_status1
I got this response

"pool_ubuntu01_443",
"vs_ubuntu_80",
"pool_ubuntu01_80"
],
"changed": false,
"failed": false
}
}
but I would like to print just key which has inside key virtualAddresses
if ""ACS-AS3".ACS.*.virtualAddresses" is defined the print the key .
the result should be
vs_ubuntu_22
vs_ubuntu_443
vs_ubuntu_80
One way to get the keys of a dict, is to use the dict2items filter. This will give vs_ubuntu_22 etc. as "key" and their sub-dicts as "value". Using this we can conditionally check if virtualAddresses is defined in values.
Also parse2.json can be included as vars_file or with include_vars rather than having a task to debug and register the result.
Below task using vars_file in playbook should get you the intended keys from the JSON:
vars_files:
- parse2.json
tasks:
- name: show atc_status
debug:
var: item.key
loop: "{{ declaration['ACS-AS3']['ACS'] | dict2items }}"
when: item['value']['virtualAddresses'] is defined
I use elb_application_lb_info module to get info about my application load balancer. Here is the code I am using for it:

I need to fetch "dns_name" which is dns name of the load balancer and pass it in another play as a variable.
I tried with json_query but got the error. Here is the code:
- name: save the Json data to a Variable as a Fact
set_fact:
jsondata: "{{ albinfo.stdout | from_json }}"
- name: Get ALB dns name
set_fact:
dns_name: "{{ jsondata | json_query(jmesquery) }}"
vars:
jmesquery: 'load_balancers.dns_name'
- debug:
msg: "{{ dns_name }}"
And here is the error:
"msg": "The task includes an option with an undefined variable. The error was: Unable to look up a name or access an attribute in template string ({{ albinfo.stdout | from_json }}).\nMake sure your variable name does not contain invalid characters like '-': the JSON object must be str, bytes or bytearray
Any idea how to extract "dns_name" from the json above?
Here is the way to get the dns_name from above json output:
- name: Get Application Load Balancer DNS Name
set_fact:
rezultat: "{{ albinfo | json_query('load_balancers[*].dns_name') }}"
- debug:
msg: "{{ rezultat }}"

As you can see, the instance ID is correct, but not well formated. Is there a way to convert this output into "human readable" output? Or is there any better way to parse the instance id from the ec2 task output?
Thanks!
It's not non-human readable format, but a list object in Python notation, because you query a list.
If you want a string, you should pass it through a first filter.
win_instance_id: "{{ ec2_result | json_query('tagged_instances[*].id') | first }}"
You can also access the value directly without json_query ([0] refers to the first element of a list):
win_instance_id: "{{ ec2_result.tagged_instances[0].id }}"
