Ansible - write only specific output

[DM]

How do you write to a file the output of a yaml?

If possible, how do you only write to a file specific info if?

Thanks

Hi,

You must create file with extension .yml and beginning this file with "---" at the top.

It's simply.

And launch file with line command "ansible-playbook my_file.yml"

This answer answers your question ?

Thanks

Thanks I do have the "---" at the top

When I run t he ansible-playbook how do get all that info to write to a file?

It only shows up on  the cli which I know I can copy and paste to a file, but would like to output to a file

Thanks

Hi,

If you want include task in your playbook, you must only do it :

- include_task: /my_path/.../.../my_file_externe.yml

This answer answers your question ?

Thanks

There's nothing in the ansible CLI that supports explicitly dumping the output to a file. You could just use a simple shell redirect.

$ ansible -i inventories/aws -m setup all > host-facts.yaml

It's worth noting that the CLI's output doesn't make a distinction between failed plays or tasks in terms of shell standard in/standard out, all the output goes to standard out (unless it's something to do with command line parsing or something lower-level than play execution).

So for example if I remove a pubkey on a host and run the setup module to gather facts, all the output goes to STDOUT:

xx.xx.xx.xx | UNREACHABLE! => {
    "changed": false,
    "msg": "Failed to connect to the host via ssh: ec2-...@xx.xx.xx.xx: Permission denied (publickey,gssapi-keyex,gssapi-with-mic).\r\n",
    "unreachable": true
}
yy.yy.yy.yy | SUCCESS => {
    "ansible_facts": {
        "ansible_all_ipv4_addresses": [

            "aa.aa.aa.aa"

        ],

Thanks to all who responded.

The example below is a yaml file to gather data from a Juniper Networks Switch device.

How would you do it this?

- name: Get Facts

  hosts: 192.168.1.1

  roles:

    - Juniper.junos

  connection: local

  gather_facts: no

  vars_prompt:

    - name: ADMUSER

      prompt: Username

      private: no

    - name: ADMPASS

      prompt: password

      private: yes

  tasks:

    - name: Retrieve LLDP Neighbor Information Using PyEZ-included Table

      juniper_junos_table:

        file: "lldp.yml"

        table: "RouteTable"

        host: '{{ inventory_hostname }}'

        user: '{{ ADMUSER }}'

        passwd: '{{ ADMPASS }}'

        port: 830

      register: response

    - name: Print response

      debug:

        var: response

    - copy: content="{{ your_json_feed }}" dest=/etc/ansible/file-1

Hello,

I've seen this use case before. It's easier to build the reporting directly into the playbook. You can, for exmaple, create a template that will print what you want for each managed host, and assemble the pieces later:

I've seen this exact same use case. It's better to build the reporting directly into the playbook. You can, for exaple, create a template that will print what you want for each managed host, and assemble the pieces later:

Something like adding a template file like:

{{ inventory_hostname }} :
{{ response }}

​

Then templating it:

- name: create part of the report for {{ inventory_hostname }}
  template:
    src: my_template.j2
    dest: "{{ inventory_hostname.report }}"

​

Then you can use the  fetch module to bring it over to the controller and the assemble module to generate a full report.

Hope that helps,

Hugo
