I am working with Ansible and in my playbook I am running the following task, in which I have multiple loops so as to retrieve different tags from a specific xml:
- name: Retrieve multiple xml tags valuei
xml:
xmlstring: "{{ item.string }}"
xpath: "{{ item.path }}"
content: text
loop:
- { path: "/rpc-reply/vlan-instance-information/vlan-instance-group/vlan-member/vlan-tag", string: "{{topology.xml}}" }
- { path: "/rpc-reply/vlan-instance-information/vlan-instance-group/vlan-member/vlan-member-interface", string: "{{topology.xml}}" }
register: tags_value
- debug:
msg: "{{ item.matches }}"
loop: "{{ tags_value.results }}"
loop_control:
label: "{{ item.matches }}"
So I am getting the following:
ok: [sss-sd1-02] => (item=[{u'vlan-member-interface': u'et-0/0/0.0*'}, {u'vlan-member-interface': u'et-0/0/1.0*'}]) => {
"msg": [
{
"vlan-member-interface": "et-0/0/0.0*"
},
{
"vlan-member-interface": "et-0/0/1.0*"
}
]
}
and this
ok: [sss-sd1-02] => (item=[{u'vlan-tag': u'4071'}, {u'vlan-tag': u'4072'}]) => {
"msg": [
{
"vlan-tag": "4071"
},
{
"vlan-tag": "4072"
}
]
}
Is there a way to group "vlan-member-interface": "et-0/0/0.0*" and "vlan-tag": "4071" in 1 result , either in this task or in a different one ? And also is there a way to create a list with only {4071, 4072} ? Because i cannot handle it as it is right now !!!
The question can be simplified. Let's have the data
results:
- [A: a1, A: a2]
- [B: b1, B: b2]
Q1: "Group "A:a1" and "B:b1" in 1 result"
A: Use zip function. For example
- set_fact:
my_groups: "{{ results.0|zip(results.1)|list }}"
- debug:
var: my_groups
gives
"my_groups": [
[
{
"A": "a1"
},
{
"B": "b1"
}
],
[
{
"A": "a2"
},
{
"B": "b2"
}
]
]
}
Q2: "Create a list with only [b1, b2]"
A: Use dict2items and json_query functions. For example
- set_fact:
my_values: "{{ results.1|map('dict2items')|list|json_query('[].value') }}"
- debug:
var: my_values
gives
"my_values": [
"b1",
"b2"
]
Question 1 is substitution of: Group "vlan-member-interface": "et-0/0/0.0*" and "vlan-tag": "4071" in 1 result
Question 2 is substitution of: Create a list with only {4071, 4072}
Variable results is substitution of tags_value.results

with_items: "{{ remote_address_phase2 }}"
if i made this activity i have 2 different task but the last operation overwrite the first
any idea?
Going by the example in the documentation for the module, it seems that the member: parameter takes a list of dicts.
Example from module documentation:
member:
-
name: "default_name_7 (source firewall.address.name firewall.addrgrp.name)"
Haven't tested it, but we can create a similar structure before "addrgrp" task with set_fact and use the newly created variable.
- set_fact:
fw_members: "{{ fw_members | default([]) + [{'name': 'NET-' ~ item}] }}"
loop: "{{ remote_address_phase2 }}"
This gives:
"fw_members": [
{
"name": "NET-192.168.88.0/24"
},
{
"name": "NET-192.168.1.0/24"
}
]
It should then be possible to pass this variable as a value to the member: parameter. Example:
- set_fact:
fw_members: "{{ fw_members | default([]) + [{'name': 'NET-' ~ item}] }}"
loop: "{{ remote_address_phase2 }}"
- name: "addrgrp"
fortios_firewall_addrgrp:
vdom: "{{ vdom }}"
state: "present"
firewall_addrgrp:
allow_routing: "disable"
#category: "default"
color: "21"
comment: "try"
exclude: "disable"
fabric_object: "disable"
member: "{{ fw_members }}"
name: "try"
type: "default"
I'm using the Cisco ACI_REST module. I'm building a playbook to shutdown all of my ACI EPGs. The ACI_EPG module is used to create the dict.
- name: Get List of EPGs
cisco.aci.aci_epg:
host: "{{ inventory_hostname }}"
username: "{{ ansible_user }}"
password: "{{ ansible_password }}"
validate_certs: no
state: query
delegate_to: localhost
register: epg_list
It creates a dictionary that looks like this:
"item": {
"key": "current",
"value": [
{
"fvAEPg": {
"attributes": {
"dn": "uni/tn-PC/ap-PROD_AP/epg-VLAN80_EPG",
"shutdown": "no",
},
"children": [
{
"fvRsBd": {
"attributes": {
"annotation": "",
"tDn": "uni/tn-PC/BD-VLAN80_BD",
"tRn": "BD-VLAN80_BD",
"tType": "name",
"tnFvBDName": "VLAN80_BD",
"uid": "0"
},
"children": [
{
"fvSubnetBDDefCont": {
"attributes": {
"name": "",
"nameAlias": "",
"status": ""
}
}
}
]
}
}
]
}
}
I need to loop through the DN values.
"dn": "uni/tn-PC/ap-PROD_AP/epg-VLAN80_EPG"
I'm playing with dict2items but am stuck. How to I reference the nested items in my dictionary? Here is some test code that I'm working with.
- name: Display EPG List
ansible.builtin.debug:
msg: "{{ item.key }} - {{ item.value }}"
loop: "{{ epg_list | dict2items }}"
Thanks,
Q: "Loop through the DN values."
A: Try json_query, e.g.
- debug:
msg: "{{ item }}"
loop: "{{ epg_list.item.value|
json_query('[].*.attributes.dn')|
flatten }}"
gives
msg: uni/tn-PC/ap-PROD_AP/epg-VLAN80_EPG
Given the data
epg_list:
item:
key: current
value:
- fvAEPg:
attributes:
dn: uni/tn-PC/ap-PROD_AP/epg-VLAN80_EPG
shutdown: 'no'
children:
- fvRsBd:
attributes:
annotation: ''
tDn: uni/tn-PC/BD-VLAN80_BD
tRn: BD-VLAN80_BD
tType: name
tnFvBDName: VLAN80_BD
uid: '0'
children:
- fvSubnetBDDefCont:
attributes:
name: ''
nameAlias: ''
status: ''
If the data is
epg_list:
current:
- fvAEPg:
attributes:
dn: uni/tn-PC/ap-PROD_AP/epg-VLAN80_EPG
shutdown: 'no'
children:
- fvRsBd:
attributes:
annotation: ''
tDn: uni/tn-PC/BD-VLAN80_BD
tRn: BD-VLAN80_BD
tType: name
tnFvBDName: VLAN80_BD
uid: '0'
children:
- fvSubnetBDDefCont:
attributes:
name: ''
nameAlias: ''
status: ''
the task below gives the same result
- debug:
msg: "{{ item }}"
loop: "{{ epg_list.current|
json_query('[].*.attributes.dn')|
flatten }}"
I'm struggling to loop over hostvars of the registered output of all the hosts in dynamic inventory.
Here is the code.
$cat collect.yaml

- hosts: "{{ env }}"
become: True
tasks:
- name: Get dockerinfo
docker_host_info:
containers: yes
register: result
- name: Debug dockerInfo
debug:

- name: dynamic grouping
add_host:

groups: "{{ item[1].Image | regex_replace('.*?/(.*?):.*', '\\1') }}"
loops:
- "{{ ansible_play_batch }}"
- "{{ hostvars[item].result.containers }}"
Error i get is item not defined. I would want the hosts refer to their respective result.containers. Not sure on how to use hostvars for the host to refer their respective result.containers.
Here is result.container output.

Any help would be greatly appreciated.
I would run this task using Images Names
- hosts: "{{ group }}"
gather_facts: false
become: true
become_method: sudo
tasks:
- name: stop or restart docker containers
command: "docker {{ state }} {{ container_name }}"
How about just group_by paired with the loop?
- hosts: "{{ env }}"
become: True
tasks:
- name: Get dockerinfo
docker_host_info:
containers: yes
register: result
- debug:
var: result.containers
- group_by:
key: "container_{{ item.image | regex_replace('.*?/(.*?):.*', '\\1') }}"
loop: "{{ result.containers }}"
- debug:
var: group_names
You don't need to add the prefix. But this would add each host to groups with their container image prefixes. You should be able to use the group later in the play or playbook.

Right now item[1].Image and item[1].Names[0] is only taken from first host's(vm1.nodekite.com) results.containers output. I would like to loop over for every hosts. So that, I could create dynamic group for all the hosts with their respective containers. With my code, hosts vm1,vm2,vm3 all are referring to vm1.nodekite.com's result.containers but i want the hosts to refer to their respective containers. Any help would be greatly appreciated.
I have update dynamic grouping task ouput for clarification.
changed: [vm1.nodekite.com] => {
"add_host": {
"groups": [
"webproxy"
],
"host_name": "vm1.nodekite.com",
"host_vars": {
"container_name": "customer1" }
},
changed: [vm1.nodekite.com] => {
"add_host": {
"groups": [
"egacustomer"
],
"host_name": "vm1.nodekite.com",
"host_vars": {
"container_name": "webproxy" }
},
changed: [vm2.nodekite.com] => {
"add_host": {
"groups": [
"webproxy" >> this should be webproxy
],
"host_name": "vm2.nodekite.com",

],
"host_name": "vm2.nodekite.com",
"host_vars": {
"container_name": "webproxy" } >> this should be webproxy

if you see vm2 is still referring to vm1's result.containers output.

I was having an issue of getting the item passed into the name below to be a plain string of: item='nginx' and not item='[u'/nginx]'
To get around this, I did the following:
- name: Get docker containers
become: docker
community.docker.docker_container
containers: yes
register: docker_info
- name: Stop running containers
become: docker
community.docker.docker_container
name: "{{ item }}"
state: stopped
loop: "{{ docker_info.containers | sum(attribute='Names', start=[]) | map('regex_replace','\\/','') | list }}"
when: item in apps.split(,)
In this case the apps is a comma deliminated string variable I passed into the ansible playbook to limit which apps to stop.
The sum piece, flattens the Names of all the apps running into a single list.
The regex piece removes the / in the Names parameter
I have an inventory in which many host_vars are set. Each host will contain a different number of datasets.
e.g.
host: host1
ip-addr: 192.0.2.12/24
datasets:
set1:
var1: 'east'
var2: 'west'
set2:
var1: 'north'
var2: 'south'
I can create a loop to count the datasets, but I don't seem able to use it to reference [varX]:
- name: "test loop"
debug:
msg:
- "{{ item }}"
- "{{ 'datasets.set' + item + '.var1' }}"
- "{{ datasets.set1.var1 }}"
loop: "{{ query('sequence', 'start=1 end='+((datasets|length)|string)) }}"
This appears to assemble the variable name I'm attempting to reference, however does not return the value associated with it. Manually calling that variable does return the interesting value.
ok: [host1] => (item=1) => {
"msg": [
"1",
"datasets.set1.var1",
"east"
]
}
ok: [host1] => (item=2) => {
"msg": [
"2",
"datasets.set2.var1",
"east"
]
}
Is what I'm doing possible, or should I be approaching it from another angle?
thanks in advance.
The task
- debug:
msg: "set{{ item }}.var1 = {{ datasets['set' ~ item].var1 }}"
loop: "{{ range(1, datasets|length+1)|list }}"
gives
"msg": "set1.var1 = east"
"msg": "set2.var1 = north"
