working with file

[nicolas stevenin]

Hi,

I have a file like : [1,2,3,4,5] 

and I want to use loop for each number in this file on the playbook (I want to use the file, not write keys in the playbook). Could you help me please ?

The playbook:  (and i need to loop on "variable_file")

    - name: Gather info about all ESXi Host in given Cluster

      vmware_host_service_info:

        validate_certs: no

        hostname: xxxxx

        username: user

        password: password

        cluster_name: "{{variable_file}}"

Thanks for your help

'Like' is ambiguous. What is like what?

Is the filename like 12345? Is the content a json list of integers? Please try to be precise.

and I want to use loop for each number in this file on the playbook (I want to use the file, not write keys in the playbook).

No idea again what 'writing keys in the playbook' means. So again please be precise. 

Could you help me please ?

    - name: Gather info about all ESXi Host in given Cluster

      vmware_host_service_info:

        validate_certs: no

        hostname: xxxxx

        username: user

        password: password

        cluster_name: "{{variable_file}}"

A wild guess, if you want to read the contents of a file ? Maybe this is what you want:

Hi,

I have a json file-> cluster_name.json :

["cluster1","cluster2","cluster3","cluster4"]

And I want to iterate on every cluster name to obtain some informations so I use the module vmware_host_service_info.

My playbook is -> vmware.yml :

---

- name: test

  hosts: localhost

  vars_files:

    - cluster_name.json

  tasks:

    - name: Gather info about all ESXi Host in given Cluster

      vmware_host_service_info:

        validate_certs: no

        hostname: hostname

        username: user

        password: password

        cluster_name: "{{cluster}}"      <-- HERE I WANT TO ITERATE ON EVERY CLUSTER_NAME IN cluster_name.json

      delegate_to: localhost

Replace vars_files with a lookup:

vars:
cluster_names: "{{ lookup( 'file', 'cluster_name.json' ) }}"

This automatically converts the file contents from JSON to a list.

You can now loop over that:

tasks:
- name: Gather info about all ESXi Host in given Cluster
vmware_host_service_info:
validate_certs: no
hostname: hostname
username: user
password: password

cluster_name: "{{ item }}"
with_items: "{{ cluster_names }}"
delegate_to: localhost
