Ansible Dynamic Inventory

How to access inventory_hostname of all the hosts of Ansible Dynamic Inventory


Here is the code.



Text

$cat collect.yaml

---

- hosts: "{{ env }}:&{{ zone }}"

become: True

tasks:

- name: Get info on docker host and list images

docker_host_info:

containers: yes

register: result



- name: Debug dockerInfo

debug:

var: result.containers

when: result.host_info.Containers != 0



- name: adding it to groups using images and vars.

add_host:

name: "{{ inventory_hostname }}"

groups: "{{ item.Image | regex_replace('.*?/(.*?):.*', '\\1') }}"

container_name: '{{ item.Names[0] | regex_replace("^/", "") }}'

with_items: "{{ result.containers | flatten(1) }}"

i'm using dynamic inventory. Here is what i run:

Text

$ansible-playbook collect.yaml -i path_of_dynamic-inventory_folder/inventory.py -e env=dev -e zone=US

here is my output,which is only picking the first host.I would like to dynamic group the rest of the hosts in the play:

YAML

TASK [Debug dockerInfo]

ok: [vm1.nodekite.com] => {

"result.containers": [

{

"Image": "ca.docker/webproxy:1.0.0",

"Names": [

"/customer1"

],

},

{

"Image": "docker.local/legacustomer:1.0.1",

"Names": [

"/webproxy"

],

},

]}

ok: [vm2.nodekite.com ] => {

"result.containers": [

{

"Image": "ca.docker/webproxy:1.0.0",

"Names": [

"/webproxyui"

],

},

{

"Image": "cna-docker-local/lega-customer:1.0.1",

"Names": [

"/webproxy"

],

},

]}

ok: [vm3.nodekite.com ] => {

"result.containers": [

{

"Image": "ca.docker/webproxy:1.0.0",

"Names": [

"/webproxy"

],

},

{

"Image": "local.docker/lega-customer:1.0.1",

"Names": [

"/customerr

],

},

]}









TASK [adding it to groups using images]

creating host via 'add_host': hostname=vm1.nodekite.com

changed: [vm1.nodekite.com] => {

"add_host": {

"groups": [

"webproxy"

],

"host_name": "vm1.nodekite.com",

"host_vars": {

"container_name": "customer1" }

},

}

PLAY RECAP:

vm1.nodekite.com : ok=3 changed=1 unreachable=0 <=====

vm2.nodekite.com : ok=2 changed=0 unreachable=0

vm3.nodekite.com : ok=2 changed=0 unreachable=0

I need to filter "{{ inventory_hostname }}" variable of all the hosts from the dynamic inventory. so that I could call module `add_host` for all hosts of the play.



I tried to alter the below code to item.inventory_hostname which doesn't work.

YAML

add_host:

name: "{{ item.inventory_hostname }}"

Could someone please assist.
