Ansible - vmware: how to find a guest on a multiple hosts vcenter? - ansible

One of the many Ansible Community.VMWare modules parameters is 'hostname', which is the name of the ESXi server.
In my case, a guest could be in one of multiple ESXi servers (8, for now), and also a new server could be added by the support team at any time.
Is there a way to find on which ESXi server a guest is? Or is it mandatory that I know this at start?
I could have a list of the ESXi servers, keep updating it on demand, and loop over this list using module 'community.vmware.vmware_guest_find' and "with_items", but actually, I don't know how would I do this (iterate over the servers, changing the 'hostname', and stopping when I finally find the guest).
Any help?

I came up with this solution below. It's necessary to have previously the list of ESXi hosts.
[...]
vars:
vcenters_hostname:
- vcenter01
- vcenter02
- ...
[...]
- block:
- name: Navigate throughout all vcenters looking for the guest
community.vmware.vmware_guest_find:
hostname: "{{ item }}"
username: "{{ vcenter_username }}"
password: "{{ vcenter_password }}"
name: "{{ guest_name }}"
validate_certs: no
delegate_to: localhost
register: guest_find_result
with_items: "{{ vcenter_hostnames }}"
rescue:
- name: Doing nothing only to don't raise a fail message
meta: noop
always:
- name: Record which vcenter and folder is the guest
ansible.builtin.set_fact:
guest_folder: "{{ item['folders'][0] }}"
vcenter_hostname: "{{ item['item'] }}"
with_items: "{{ guest_find_result['results'] }}"
when: item['failed'] == false

Ansible Playbook with include_tasks

I have an Ansible playbook called main.yml that builds a Windows VM using an OVF template. It then configures the VM using variables that I pass. Typical Ansible stuff.
What I would like to do is have another task inside the main.yml run at the end that configures a couple things on the VM (configureserver.yml). I pass "{{ vmName }}" as a variable in the main.yml, and want the 2nd playbook (configureserver.yml) to run against that `"{{ vmName }}" variable.
Main.yml (removed some of the customization to shorten this post)
- name: Deploy Virtual Machine from an OVF template in content library
community.vmware.vmware_content_deploy_ovf_template:
name: "{{ vmName }}"
hostname: "{{ vcenterName }}"
username: "{{ vmwareUser }}"
password: "{{ vmwarePassword }}"
template: "{{ templateName }}"
- name: Configure the VM
community.vmware.vmware_guest:
name: "{{ vmName }}"
hostname: "{{ vcenterName }}"
username: "{{ vmwareUser }}"
password: "{{ vmwarePassword }}"
datacenter: "{{ datacenterName }}"
cluster: "{{ clusterName }}"
datastore: "{{ datastoreclusterName }}"
# THIS IS WHAT I WANT TO ADD
- name: Configure the D Drive
include_tasks:
file: configureserver.yml
configureserver.yml
- hosts: "{{ vmName }}"
gather_facts: no
become: yes
vars_files:
- passwords.yml
- vars.test.yml
vars:
- ansible_connection: ssh
- ansible_shell_type: cmd
- ansible_become_method: runas
- ansible_become_user: System
In the code above, I want to run a separate task in a separate yml that will configure the server. I want to run the configureserver.yml playbook against the "{{ vmName }}" variable as the inventory or host.
Glad to provide more details if needed.
I figured it out. I changed the include_tasks to include_playbook and that did the trick

Setting Ansible vars with set_fact results

Im running ansible 2.9.18 on RHEL7.
I am using hvac to retrieve usernames and passwords from a Hashicorp vault.
vars:
- creds: "{{ lookup('hashi_vault', 'secret=tst2/data/cisco token= url=http://10.80.23.81:8200') }}"
tasks:
- name: set Cisco creds
set_fact:
cisco: "{{ creds['data'] }}"
- name: Get nxos facts
nxos_command:
username: "{{ cisco['username'] }}"
password: "{{ cisco['password'] }}"
commands: show ver
timeout: 30
register: ver_out
- debug: msg="{{ ver_out.stdout }}"
But username and password are deprecated and I am trying to figure out how to pass the username, password as a "provider" variable. And this code doesn't work:
vars:
asa_api:
- creds: "{{ lookup('hashi_vault', 'secret=tst2/data/cisco token= url=http://10.80.23.81:8200') }}"
set_fact:
cisco: "{{ creds['data'] }}"
username: "{{ cisco['username'] }}"
password: "{{ cisco['password'] }}"
tasks:
- name: show run
asa_command:
commands: show run
provider: "{{ asa_api }}"
register: run
become: yes
tags:
- show_run
I cannot figure how syntax for making this work. I would greatly appreciate any help.
Thanks,
Steve
Disclaimer: This is a generic answer. I do not have any network device to test this fully so you might have to adapt a bit after reading the documentation
Your are taking this the wrong way. You don't need set_fact at all and both method you are trying to use (user/pass or provider dict) are actually deprecated. Ansible treats you network device as any host and will use the available user and password you have configured if they exist.
In the following example, I'm assuming your playbook only targets network devices and that the login/pass stored in your vault is the same on all devices.
- name: Untested network device connection configuration demo
hosts: my_network_device_group
vars:
# This indicates which connection plugin to use. Default is ssh
# An other possible value is httpapi. See above documentation link
ansible_connection: network_cli
vault_secret: tst2/data/cisco
vault_token: verysecret
vault_url: http://10.80.23.81:8200
vault_options: "secret={{ vault_secret }} token={{ vault_token }} url={{ vault_url }}"
creds: "{{ lookup('hashi_vault', vault_options).data }}"
# These are the user and pass used for connection.
ansible_user: "{{ creds.username }}"
ansible_password: "{{ creds.password }}"
tasks:
- name: Get nxos version
nxos_command:
commands: show ver
timeout: 30
register: ver_cmd
- name: show version
debug:
msg: "NXOS version on {{ inventory_hostname }} is {{ ver_cmd.stdout }}"
- name: An other task to play on targets
debug:
msg: "Task played on {{ inventory_hostname }}"
Rather than vars at play level, you can store this information in your inventory for all hosts or for a specific group, even for each host. See how to organise your group and host variables if you want to use that feature.

Is there an rest api or ansible module to register an VM in vCenter

I know we can do this in PowerCli, but would like to know if there is any other method to register an VM in vcenter like using vcenter api or ansible ?
For migrating a machine vCenter A to vCenter B, my vRO does not have access to the vcenterB, but I need to register the machine in vCenter B. It would be easy if I can use rest api or ansible module to do it or is there a way I can use VMWare converter with vRO ?
Here recently a module was added to Ansible that can do just that. The module: https://github.com/ansible/ansible/blob/devel/lib/ansible/modules/cloud/vmware/vmware_guest_register_operation.py
Some example code:
- name: Register VM to inventory
vmware_guest_register_operation:
hostname: "{{ vcenter_hostname }}"
username: "{{ vcenter_username }}"
password: "{{ vcenter_password }}"
validate_certs: no
datacenter: "{{ datacenter }}"
folder: "/vm"
esxi_hostname: "{{ esxi_hostname }}"
name: "{{ vm_name }}"
template: no
path: "[datastore1] vm/vm.vmx"
state: present

Ansible Module vmware_host_facts only returning one Host

I'm playing around with Ansible VMWare Modules and tried to get all the Information from ESXi Hosts from a vCenter.
With the Module vmware_host_facts it should be possible.
But when I run a Playbook with the following configuration, I only get the Information of one Host back - and not all. In this vCenter there are about 20 Hosts.
Playbook:
- name: Gather vmware host facts
vmware_host_facts:
hostname: vCenter_IP
username: username
password: password
register: host_facts
delegate_to: localhost
In the Documentation it tells me, that the hostname can also be a vCenter IP.
Resource:
http://docs.ansible.com/ansible/latest/modules/vmware_host_facts_module.html#vmware-host-facts
Is that module not the correct one to gather all host information from a vCenter? Or is there a "hidden trick", which I am missing?
Thanks a lot!
Kind regards,
M
I got an answer on another resource.
https://github.com/ansible/ansible/issues/43187
Basically you have to add the Hostnames as a list to the Task.
Example:
- name: Gather vmware host facts
vmware_host_facts:
hostname: "{{ item.esxi_hostname }}"
username: "{{ item.esxi_user }}"
password: "{{ item.esxi_pass }}"
validate_certs: no
register: host_facts
delegate_to: localhost
with_items:
- {esxi_hostname: hostname_1, esxi_user: username_host_1, esxi_pass: pass_host_1}
- {esxi_hostname: hostname_2, esxi_user: username_host_2, esxi_pass: pass_host_2}
These Hostnames you can gather with another module - vmware_vm_facts. Here you can get the Hostnames from. I will update this with an example playbook in the near future.
I use this module with these options, so far I have one issue if I put vcenter address it only give me first Esxi output.
- name: Somethign.
vmware_host_facts:
hostname: '{{ vcenter_hostname }}'
username: '{{ vcenter_user }}'
password: '{{ vcenter_pass }}'
validate_certs: no
register: all_cluster_hosts_facts
delegate_to: localhost
- debug: var=all_cluster_hosts_facts

Ansible - How to loop and get attributes of new EC2 instances

I'm creating a set of new EC2 instances using this play
- hosts: localhost
connection: local
gather_facts: False
tasks:
- name: Provision a set of instances
ec2:
assign_public_ip: yes
aws_access_key: XXXXXXXXXX
aws_secret_key: XXXXXXXXXX
group_id: XXXXXXXXXX
instance_type: t2.micro
image: ami-32a85152
vpc_subnet_id: XXXXXXXXXX
region: XXXXXXXXXX
user_data: "{{ lookup('file', '/SOME_PATH/cloud-config.yaml') }}"
wait: true
exact_count: 1
count_tag:
Name: Demo
instance_tags:
Name: Demo
register: ec2
- name: Add new CoreOS machines to coreos-launched group
add_host: hostname="{{ item.public_ip }}" groups=coreos-launched
with_items: "{{ ec2.instances }}"
- name: Wait for SSH to come up
wait_for: host="{{ item.public_dns_name }}" port=22 delay=60 timeout=320
with_items: "{{ ec2.instances }}"
Now, I need to create an SSL/TLS certificate for every of those new machines. To do so, I require their private IP. Yet, I don't know how to access the "{{ ec2.instances }}" I registered in the previous play.
I tried something, in the same playbook, to do something like this
- hosts: coreos-launched
gather_facts: False
tasks:
- name: Find the current machine IP addresse
command: echo "{{ item.private_ip }}" > /tmp/private_ip
with_items: "{{ ec2.instances }}"
sudo: yes
But without any success. Is there a way to use the "{{ ec2.instances }}" items inside a same playbook but in a different play?
-- EDIT --
Following Theo advices, I manage to get the instances attributes using
- name: Gather current facts
action: ec2_facts
register: ec2_facts
- name: Use the current facts
command: echo "{{ ec2_facts.ansible_facts.ansible_ec2_local_ipv4 }}"
with_items: "{{ ec2_facts }}"
The best way to learn about a return structure (short of the documentation) is to wrap it in a debug task.
- name: Debug ec2 variable
debug: var=ec2.instances
From there, follow the structure to get the variable you seek.
Also (following the idempotence model), you can use the ec2_remote_facts module to get the facts from the instances and call them in future plays/tasks as well.
See Variables -- Ansible Documentation for more info about calling registered variables.
