I'm unsure if the title matches to what I'm trying to ask but I didn't know what other title to use.
So my question:
What I'm trying to do is gather disk info from VMWare and post the output of capacity_in_kb for EACH disk in a file (but currently only debug).
- name: Gather disk info from virtual machine
community.vmware.vmware_guest_disk_info:
hostname: "{{ lookup('ansible.builtin.env', 'VMWARE_HOST') }}"
username: "{{ lookup('ansible.builtin.env', 'VMWARE_USER') }}"
password: "{{ lookup('ansible.builtin.env', 'VMWARE_PASSWORD') }}"
validate_certs: no
name: "{{ ansible_hostname }}"
datacenter: "{{ lookup('ansible.builtin.env', 'VMWARE_HOST') }}"
delegate_to: 127.0.0.1
register: disk_info
- debug:
var: disk_info
This outputs the following:
{
"disk_info": {
"guest_disk_info": {
"0": {
"key": 2000,
"label": "Hard disk 1",
"summary": "16,777,216 KB",

"capacity_in_kb": 262144000,

}
},

},

"changed": false
}
We now want to get capacity_in_kb for every disk. Some VMs only have one disk attached, some have two, some three and so on...
We tried
- name: with_dict
ansible.builtin.debug:
msg: "{{ item.value.label }} - {{ item.value.capacity_in_kb }}"
loop: "{{ disk_info.guest_disk_info|dict2items }}"
but that also doesn't work for us and only gives us the output of the first disk [0] in the list.
Does anyone have an idea? Thanks in advance :)
Edit: as #β.εηοιτ.βε pointet out it's
- loop: "{{ disk_info|dict2items }}"
+ loop: "{{ disk_info.guest_disk_info|dict2items }}"
but still it only iterates over the first disk and not the second, third, etc..
EDIT2: it worked, but I just didn't see it...dumb me
If you want to iterate the data, the task below
- debug:
msg: "{{ item.value.label }}: {{ item.value.capacity_in_kb }}"
loop: "{{ disk_info.guest_disk_info|dict2items }}"
loop_control:
label: "{{ item.key }}"
gives
ok: [localhost] => (item=0) =>
msg: 'Hard disk 1: 16777216'
ok: [localhost] => (item=1) =>
msg: 'Hard disk 2: 262144000'
The next option is to avoid the iteration and create a dictionary
label_capacity_q: '*.[label, capacity_in_kb]'
label_capacity: "{{ dict(disk_info.guest_disk_info|
json_query(label_capacity_q)) }}"
gives
label_capacity:
Hard disk 1: 16777216
Hard disk 2: 262144000
Example of a complete playbook for testing
- hosts: localhost
vars:
label_capacity_q: '*.[label, capacity_in_kb]'
label_capacity: "{{ dict(disk_info.guest_disk_info|
json_query(label_capacity_q)) }}"
tasks:
- debug:
var: label_capacity
- debug:
msg: "{{ item.key }}: {{ item.value }}"
loop: "{{ label_capacity|dict2items }}"
- debug:
msg: |-
{% for k,v in label_capacity.items() %}
{{ k }}: {{ v }}
{% endfor %}
gives (abridged)

i have to create a firewall group

name: "try"
type: "default"
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 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"
I'm not sure if i'm taking the correct way but i have the next problem.
I need a simple task like:
- name: Copying files
template:
src: "{{ item[1] }}.j2"
dest: "{{ path }}/{{ item[0] }}/{{ item[1] }}"
with_nested:
- [ 'env1' , 'env2' ]
- [ 'file1' , 'file2']
Actual results:
/path/env1/file1
/path/env1/file2
/path/env2/file1
/path/env2/file2
Expected results:
/path/env1/file1
/path/env2/file2
I just need that file1 generate template in directory env1 and the file2 generate template in env2.
I can't do it with a simple 'with_items' because i hace 2 items to iterate, the name of the directory and the name of the file.
I'm sure that there is a way to do that correctly..
Thanks in advance
Use zip filter. The play below
- hosts: localhost
vars:
list1: [ 'env1' , 'env2' ]
list2: [ 'file1' , 'file2']
tasks:
- debug:
msg: "/path/{{ item.0 }}/{{ item.1 }}"
loop: "{{ list1|zip(list2)|list }}"
gives (grep msg):
"msg": "/path/env1/file1"
"msg": "/path/env2/file2"
you can try following to get expected results :
- name: Copying files
template:
src: "{{ item[1] }}.j2"
dest: "{{ path }}/{{ item[0] }}/{{ item[1] }}"
with_together:
- [ 'env1' , 'env2' ]
- [ 'file1' , 'file2']

I have an Ansible playlist which registers a return variable:
- name: Create Instance
ec2_instance:
aws_access_key: "{{access_key}}"
aws_secret_key: "{{secret_key}}"
key_name: ***
instance_type: t2.micro
security_group: ***
image_id: ami-39f8215b
region: ***
register: details
So the details is a JSON object like this:
{
"details": {
"changed": false,
"changes": [],
"failed": false,
"instance_ids": [
"i-1111abcde"
],
...
}
All I want to do is write a text file with each instance_id in there:
i-1111abcde
I've tried all of the following, none working:
debug:
var: item
with_items: details['instance_ids']
debug:
var: item.item
with_items: details['instance_ids']
debug:
var: details.instance_ids
with_items: details
# This works, but prints the entire JSON array...
Solution
- name: Debug Info
debug:
var: item
loop: "{{details.instance_ids}}"
- name: Write Temp File
lineinfile:
path: /tmp/temp.txt
line: "{{ item }}"
loop: "{{ details.instance_ids }}"
Note: loop is a more modern Ansible concept that with_items or with_*
