Parsing dictionary from VMware module - ansible

I'm using ansible community.vmware.vmware_datacenter_info.I only want to get the name of my several datacenter in vCenter.
Here is my play:
---
- hosts: localhost
gather_facts: False
tasks:
- name: Gather information about all datacenters
community.vmware.vmware_datacenter_info:
hostname: "{{ vCenter }}"
username: "{{ vCenter_username }}"
password: "{{ vCenter_password }}"
validate_certs: False
delegate_to: localhost
register: result
Here is the output of my variable result:
TASK [Print the gateway for each host when defined] ********************************
ok: [localhost] => {
"msg": {
"changed": false,
"datacenter_info": [
{
"config_status": "gray",
"moid": "datacenter-271",
"name": "Sample_DC_1",
"overall_status": "gray"
},
{
"config_status": "gray",
"moid": "datacenter-276",
"name": "Sample_DC_2",
"overall_status": "gray"
}
],
"failed": false
}
}
What I would like to get is only the name for both datacenter: Sample_DC_1 and Simple_DC_2 so I can use them in another play.
What I tried:
- name: Display datacenter name
debug:
msg:
- "{{ item.value.name }}"
loop: "{{ lookup('dict', result) }}"
Result:
fatal: [localhost]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'bool object' has no attribute 'name
if I only try to display "Key: {{ item.key }}" & " Value: {{ item.value }}" I got this output:
"msg": [
"Key : datacenter_info Value : [{'name': 'Sample_DC_1', 'moid': 'datacenter-271', 'config_status': 'gray', 'overall_status': 'gray'}, {'name': 'Sample_DC_2', 'moid': 'datacenter-276', 'config_status': 'gray', 'overall_status': 'gray'}]"
]
How can I register my both datacenter's name in a var so I can re-use them later in the playbook?

Q: "Get the names of both datacenter."
A: Map the attribute
dc_names: "{{ result.datacenter_info|map(attribute='name')|list }}"
Example of a complete playbook for testing
- hosts: localhost
vars:
result:

datacenter_info:
- config_status: gray

name: Sample_DC_1
overall_status: gray
- config_status: gray
moid: datacenter-276
name: Sample_DC_2
overall_status: gray
failed: false
dc_names: "{{ result.datacenter_info|map(attribute='name')|list }}"
tasks:
- debug:
var: dc_names
gives
dc_names:
- Sample_DC_1
- Sample_DC_2

To collect backing_datastore from the vmware_guest_disk_info module output

I'm using the below tasks in the playbook to find the backing datastore in the vmware but I tried various options, which is not helping to gather the backing_datastore name, kindly suggest how to fetch:
- name: Take Snapshot

tasks:
- name: Gather data of the registered virtual machines
community.vmware.vmware_vm_info:

password: '{{ vcenter_password }}'
vm_type: vm
validate_certs: no
delegate_to: localhost
register: vminfo
- debug:
msg: "{{ item.datacenter }}"
loop: "{{ vminfo.virtual_machines}}"

Kindly suggest how can I fetch the backing_datastore from the above mentioned output.
The result is a list because there might be more items with the attribute backing_datastore. For example,
backing_datastores: "{{ disk_fact.results|json_query(_query) }}"
_query: '[].guest_disk_info[].*.backing_datastore'
gives
backing_datastores:
- - ENV04
If you want the first one
backing_datastore: "{{ backing_datastores|flatten|first }}"
gives
backing_datastore: ENV04
If you want to iterate results
- debug:
msg: "{{ item.guest_disk_info['0'].backing_datastore }}"
loop: "{{ disk_fact.results }}"
loop_control:
label: "{{ item.item.ip_address }}"
when: not item.skipped|d(false)
gives the attribute backing_datastore of the disk "0"

Ansible adding items to nested list

starting data:
ok: [test#test.com] => {
"msg": {
"testdb1": {
"dbe_user_not_in_db": [
"test_user1",
"test_user2"
],
}
}
}
I currently have the following in ansible:
- name: Create dbe_pass_pairs
set_fact:
ora_sid_home_map: "{{ora_sid_home_map|combine({ item[0].key: {'dbe_pass_pairs': {item[1]: password} }}, recursive=True)}}"
loop: "{{ ora_sid_home_map | dict2items | subelements('value.dbe_user_not_in_db') }}"
vars:
password: "{{ lookup('password', '/dev/null length=10 chars=ascii_letters,digits') }}"
Which yields:
ok: [test#test.com] => {
"msg": {
"testdb1": {
"dbe_pass_pairs": {
"test_user1": "4SS2kJ7p0z",
"test_user2": "VLIzNfoaxf"
},
"dbe_user_not_in_db": [
"test_user1",
"test_user2"
],
}
}
}
Instead of dbe_pass_pairs containing dictionary items I'd like them to be a list of strings like such with a semicolon as:
ok: [test#test.com] => {
"msg": {
"testdb1": {
"dbe_pass_pairs": [
"test_user1;4SS2kJ7p0z",
"test_user2;VLIzNfoaxf"
],
"dbe_user_not_in_db": [
"test_user1",
"test_user2"
],
}
}
}
Doing something like the following just overwrite the list instead of appending:
- name: Create dbe_pass_pairs
set_fact:
ora_sid_home_map: "{{ora_sid_home_map|combine({ item[0].key: {'dbe_pass_pairs': [item[1] + ';' + password] }}, recursive=True)}}"
loop: "{{ ora_sid_home_map | dict2items | subelements('value.dbe_user_not_in_db') }}"
vars:
password: "{{ lookup('password', '/dev/null length=10 chars=ascii_letters,digits') }}"
"dbe_pass_pairs": [
"test_user2;AxL6ayeZIH"
],
Any idea how to get what I'm looking for data wise?
a solution using jinja2:
- name: Reproduce issue
hosts: localhost
gather_facts: yes
vars:
ora_sid_home_map:
testdb1:
dbe_user_not_in_db: ["test_user1", "test_user2"]

{%- if ns.result.append(user ~ ';' ~ password) -%}{%- endif -%}
{%- endfor -%}
{{ {ns.ident: ora_sid_home_map[ns.ident] | combine({'dbe_pass_pairs': ns.result})} }}
- debug:

}
}
}
without jinja2:

Ansible register variable iteration issue with var.results

Below is the code which hold values in a register variable:
- name: "Install Msi on the Server - {{item.app_name}}"
win_package:
path: d:\temp_deploy\{{servergroup_variable}}_{{release_variable}}.{{build_variable}}\{{ item.app_name }}_{{ item.app_expectedversion }}.msi
state: present
arguments: "INSTALLDIR={{ item.app_installPath }} SELECTEDREGION={{ environment_variable }} ALLUSERS=1 /L*V c:\\log\\Deployment-{{ item.app_name }}.log"
retries: 3
register: task_result
until: task_result.failed == true
when: (item.app_type == "webService") or
(item.app_type == "Service" )
ignore_errors: yes
register: msi_deploy_var
After I run the msi_deploy_var, it holds the following results:
ok: [server1] => {
"msg": {
"changed": false,
"failed": false,
"reboot_required": false
}
}
ok: [server2] => {
"msg": {
"changed": true,
"failed": false,
"rc": 0,
"reboot_required": false
}
}
Now the real problem starts - when I tried to iterate on msi_deploy_var then its working as expected.
- name: "Validate Success deploy - {{item.app_name}}"
set_fact:
msi_deploy_result: "{{msi_deploy_result + [item.app_name]}}"
when: (inner_item.rc is defined) and (inner_item.rc != 0)
with_items: "{{ msi_deploy_var.results }}"
loop_control:
loop_var: inner_item
But its always skipping conditional evaluation.
Any help would be appreciated.

Setting multiple values in sysctl with Ansible

I have a playbook with several tasks setting values to sysctl. Instead of having a task for each setting, how can I set all the values with one task, using the sysctl module?
Playbook snippet:
- name: Set tcp_keepalive_probes in sysctl
become: yes
sysctl:
name: net.ipv4.tcp_keepalive_probes
value: 3
state: present
reload: yes
- name: Set tcp_keepalive_intvl in sysctl
become: yes
sysctl:
name: net.ipv4.tcp_keepalive_intvl
value: 10
state: present
reload: yes
- name: Set rmem_default in sysctl
become: yes
sysctl:
name: net.core.rmem_default
value: 16777216
state: present
reload: yes
define all the variables in a var file:
e.g.
sysctl:
- name: test
value: test
...
...
playbook:
- hosts: "{{ }}"
tasks:
- name: update sysctl param
sysctl:
name: "{{ item.name }}"
value: "{{ item.value }}"
state: present
reload: yes
with_items:
- "{{ hosts }}"
Simple solution: define variable as a dict
Example playbook:
---
- hosts: all
gather_facts: false
become: true
vars:
ansible_python_interpreter: /usr/bin/python3
sysctl_config:
net.ipv4.ip_forward: 1
net.ipv4.conf.all.forwarding: 1
net.ipv6.conf.all.forwarding: 1
tasks:
- name: Change various sysctl-settings
sysctl:
name: '{{ item.key }}'
value: '{{ item.value }}'
sysctl_set: yes
state: present
reload: yes
ignoreerrors: yes
with_dict: '{{ sysctl_config }}'
Output:
TASK [Change various sysctl-settings] **********************************************************************************************************************************************************************

Create an AMI using ansible ec2_ami module and grab snapshot_id(s) from registered variable

I have the following playbook:
- hosts: localhost
connection: local
gather_facts: False
tasks:
- name: Read Variables
include_vars:
file: variables.yml
- name: Create AMI
ec2_ami:
aws_access_key: "{{ ACCESS_KEY }}"
aws_secret_key: "{{ SECRET_KEY }}"
region: "{{ AWS_REGION }}"
delete_snapshot: yes
instance_id: "{{ ID_INSTANCE }}"
name: "{{ SUFFIX_BACKUP }}-{{ NAME_BACKUP }}"
wait: yes
description: "{{ DESCR }}"
tags:
project: project1
register: ami_data
Example content of "ami_data" variable:
"msg": {
"architecture": "x86_64",
"block_device_mapping": {
"/dev/sda1": {
"delete_on_termination": true,
"encrypted": false,
"size": 30,
"snapshot_id": "snap-0e95eac98734af1d1",
"volume_type": "gp2"
}
},
"changed": false,
"creationDate": "2017-12-13T17:02:47.000Z",
"description": "descripition",
"failed": false,
"hypervisor": "xen",
"image_id": "ami-XXXXXX",
"is_public": false,
"launch_permissions": {},
"location": "457841571138/MYAMINAME",
"msg": "AMI not updated",
"name": "MYAMINAME",
"ownerId": "XXXXXXXXXX",
"platform": null,
"root_device_name": "/dev/sda1",
"root_device_type": "ebs",
"state": "available",
"tags": {
"project": "project1",
},
"virtualization_type": "hvm"
}
}
And now I want to grab the "snapshot_id" that was registered on "ami_data" variable for every disk on it. I have tried the following debug tasks using "msg" to show the value(s) of "snapshot_id" but non of them worked. What I'm doing wrong?
- name: Show data
debug:
msg: "{{ ami_data.block_device_mapping[*].snapshot_id }}"
- name: Show data
debug:
msg: "{{ ami_data.block_device_mapping[/dev/sda1].snapshot_id }}"
- name: Show data
debug:
msg: "{{ ami_data.block_device_mapping./dev/sda1.snapshot_id }}"
- name: Show data
debug:
msg: "{{ ami_data.block_device_mapping.[*].snapshot_id }}"
This one works:
- name: Show data
debug:
msg: "{{ ami_data.block_device_mapping }}"
And give me the following:
ok: [localhost] => {
"msg": {
"/dev/sda1": {
"delete_on_termination": true,
"encrypted": false,
"size": 30,
"snapshot_id": "snap-0ea846d9aca82b51f",
"volume_type": "gp2"
}
}
}
Firstly, with the ami_data.block_device_mapping you have to iterate with the list and after search under the map with the key name of the element (snapshot_id in this case):
- debug:
msg: {{ item }}
with_items: "{{ ami_data.block_device_mapping|map(attribute='snapshot_id')|list}}"
You were really close. Use square brackets but use quotes to specify literals:
- name: Show data
debug:
msg: "{{ ami_data.block_device_mapping['/dev/sda1'].snapshot_id }}"
or using variables:
- name: Show data
debug:
msg: "{{ ami_data.block_device_mapping[item].snapshot_id }}"
with_items: "{{ ami_data.block_device_mapping }}"
