How can I print all extra-vars before playbook is started

I have wired problem with running ansible

I'd like to print to log or anywhere else the extra-vars I'm executing the playbook with.

I am running the following command:

ansible-playbook /foo/main.yml --extra-vars "main_playbook=app_install  start_path=work" --extra-vars  {"db_config":{"db_multi_config":["value1","value2"]}}'

with the following main.yml playbook

- name: start playbook
  import_playbook: "{{ playbook_dir }}/{{ main_playbook}}/{{ start_path}}.yml"

I'd like to print the values of all extra-vars passed on the command line before it gets to main.yml. Is there any way to do this?

You can get this information in the output running ansible in full debug mode:

Given the following test.yml playbook:

- hosts: localhost
  gather_facts: false

and running it with the command:

ansible-playbook test.yml -vvvv -e toto=bla -e '{"test1":2}'

I get the following result (see the debug lines for playbook before play starts)

ansible-playbook [core 2.11.3]

You can't separate extra vars from all other vars, because they are merged. But you can see all variables for the host. (except for setup facts, which you can browse separately with -m setup).

The trick is to print all variables from hostvars group for 'itself', ansible_host:

ansible -i inventory -e extra_vars_here -m debug -a 'msg={{hostvars[inventory_hostname]}}' all

(replace all with specific hostname if you wish).

If you are overwhelmed, you can filter it with .keys(): hostvars[inventory_hostname].keys().
