Problems with VMWARE and In-Memory Inventory

Archives Ansible Project
1

Hi all,
I don’t know what I do wrong… I try create VMs (vmware) and provisioning after that. But when try add this new vms to inventory with add_host only add one.

The task “Gather VM facts (vmware_guest_facts)” recover 2 IPs but then “Add Host to inventory” only add one IP to in-memory inventory.

I try multiples scenarios (with_dict/set_fact…) to add_host to inventory but nothing work!

Any idias what I do wrong, any suggestions?

Thxs,

Mariano

Hello,

The probleme seems that Ansible do not that it needs to loop on the add_host part, since there is no parameter like {{ inventory_hostname }} to indicate it needs to loop on it.

Maybe if you try to add a false variable set to the inventory_hostname, it could help it to loop ?
Should look like this :

  • name: Add Host to inventory
    add_host:
    hostname: “{{ vm_facts.ansible_facts.hw_eth0.ipaddresses[0] }}”
    groups: in-memory-vms
    ansible_ssh_host: “{{ vm_facts.ansible_facts.hw_eth0.ipaddresses[0] }}”
    ansible_user: root
    ansible_password: xxxxxxxxx
    ansible_distribution: “CentOS”
    ansible_system: “Linux”
    foo: {{ inventory_hostname }}

Hi Sebastien,
I try with a loop but the result it’s the same. Only add one of both. Learn05 (.232.141)

The loop:

`

  • name: DEBUG Show inventory_hostname
    debug: msg=“inventory_hostname {{inventory_hostname}}”

  • name: Add_host with Loop
    add_host:
    name: “{{item.value.ipv4}}”
    groups: in-memory-vms
    ansible_ssh_host: “{{item.value.ipv4}}”
    ansible_distribution: “CentOS”
    ansible_system: “Linux”
    ansible_ssh_private_key_file: /root/.ssh/ansible.pem
    with_dict: “{{ instance_facts }}”
    when: item.key in [‘instance’]
    changed_when: false

`

When execute the new playbook, only added learn05, but the debug in “TASK [vmware : DEBUG Show inventory_hostname]” show two hosts.

In the common role I added a debug line “TASK [common : debug]” to show all groups outside of vmware role. If you can see the in-memory-vms group have only one IP learn05 (.232.141)

[root@learn01 ansible]# ./createvm.yml

Hi,

Ansible 2.5 is not stable as of now… I would recommend to use 2.3.x or 2.4.y version to use in production…
Anyway this is not the problem here.
As written in documentation, add_host broke loop_play (in note section : This module bypasses the play host loop and only runs once for all the hosts in the play, if you need it to iterate use a with_ directive). So it works as defined

JYL

Hi,

There’s a loop indeed, but I thinks there’s something wrong in your variable because it is looping with
first iteration item.key ==> 'instance"
second iteration item.key ==> ‘attempts’
third_iteration item.key ==> ‘changed’,
fourth iteration item.key ==> ‘failed’

So it’s more a bug in your variable you are using than the loop itself which the problem lies…

Regards,

JYL

Hello,

For my part, I’m using the way described by JYL.

`

  • include_role:
    name: myrolewhoaddsininventory
    with_items: “{{ mylist }}”
    `

the add_host task is included amonfg other things in the role.
And at the end, I get the in-memory inventory properly filed.

Hi Jean,

About this:

There’s a loop indeed, but I thinks there’s something wrong in your variable because it is looping with
first iteration item.key ==> 'instance"
second iteration item.key ==> ‘attempts’
third_iteration item.key ==> ‘changed’,
fourth iteration item.key ==> ‘failed’

In the loop I use “when: item.key in [‘instance’]” because the facts have others keys I need ignore.

About now, I downgrade ansible to 2.4 and remove the loop but the behaviour it’s the same.

[root@learn01 ansible]# ansible --version
ansible 2.4.0.0 config file = /etc/ansible/ansible.cfg configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules'] ansible python module location = /usr/lib/python2.7/site-packages/ansible executable location = /usr/bin/ansible python version = 2.7.5 (default, Aug 4 2017, 00:39:18) [GCC 4.8.5 20150623 (Red Hat 4.8.5-16)]

Hi Sebastien,
You have a role to create VMs and other to add_host to inventory? I try it and send you a feedback soon.

Thxs!

Hello

I use the same role to create the VM and add_host.
This way, with the first item, it creates the VM and add it to the in-memory inventory.
Then it loops and do the same with the second item.
Etc…
Unless you destroy your in-memory inventory at some point, it will be available and used through all the play.

Best Regards,

Ok now all work fine, I make some mistakes!!!

Downgrade to stable Ansible version just like suggested Jean solved different issues like “wait_for_ip_address: true” in ansible 2.4 work but in 2.5 not.

Now I don’t use in-memory inventory, I solve it setting ansible_ssh_host, because the server exist in the inventory and I don’t need duplicate it.
