ansible-dumpall's Introduction

Dumpall

Dump all remote variables and optionally copy the result to a destination on the host.

Based on the excellent work by Lester Wade!

Requirements

None.

Role Variables

dumpall_flat_mode: yes
dumpall_guest_destination: /tmp/ansible.all
dumpall_host_destination: /somewhere/local/

Role Tags

ansible-dumpall
ansible-dumpall-all-vars
ansible-dumpall-retrieve-dumpfile
ansible-dumpall-remove-dumpfile-guest

Example Playbook

Example without a host_destination will result in a dumpfile /tmp/ansible.all on the guest:

- hosts: servers
  roles:
     - f500.dumpall

Example with a host_destination will result in a dumpfile /examine/ansible.all on the host machine: (the dumpfile on the guest is removed)

- hosts: servers
  roles:
     - { role: f500.dumpall, dumpall_host_destination: /examine/ }

If you also set the flat_mode to false, the local filename will be the entire path of the guest_destination, prepended by the hostname of the current play. See the Ansible fetch module for more information.

ansible-dumpall's Issues

Exception when running on ansible 2.1.0.0

It worked pre 2.0.

TASK [f500.dumpall : Dump all vars] ********************************************

Please consider tagging releases without the "v" prefix

Can you tag versions using just the number?

eg,2.0.2 rather than v2.0.2? It's more consistent with how most projects/roles version things and makes the requirements.yml file cleaner... right now I have to do:

- src: f500.dumpall  # from Ansible Galaxy
  version: v2.0.2

New release needed for Ansible Galaxy

It would be great for a new release to be rolled. Specifically, so PR#11 is zipped up and then available to ansible galaxy. This is a handy little role, thanks.

Interested in Changing this to use delegate_to: localhost ?

As written the code works for individual servers. But it's possible to get a report of EVERYTHING on the localhost without ever touching the remote servers to generate the report. If interested I can send a pull request with all the changes. Then we can discuss the implications.

The extensions I've made could also take this from a pure Role to an included playbook. - if desired! - The way I use this to have the following one-liner at the end of all my playbooks:

include: roles/dumpvars/dumpvars.pb
instead of
host: localhost
roles:
- dumpvars

Two things are needed

use delegate_to: localhost.
to get variables for all hosts you need a bit of extra magic. See below.

"hostvars": {
{% for key in groups["all"] %}
"{{key}}": {{ hostvars[key] |to_nice_json }}
,
{% endfor %}
