Hi,
I've created quite simple python module for installation and execution of
multihost tests. And because of synchronization between the hosts, I need
to generate "random" string/id/whatever and pass it to each test and it has
to be the same for all hosts in one test. (But it has to be different when
I'll rerun the ansible playbook.)
Current solution looks like this: I'll locally create random string in
separate task before the test execution and pass it as argument to the
run_test module (named uuid):
- name: generate uuidgen for test1
command: uuidgen
run_once: true
delegate_to: localhost
register: uuid
- name: run test1
run_test: name=test1 unique_id="{{ uuid.stdout_lines[0] }}"
- name: generate uuidgen for test2
command: uuidgen
run_once: true
delegate_to: localhost
register: uuid
- name: run test2
run_test: name=test2 unique_id="{{ uuid.stdout_lines[0] }}"
- name: generate uuidgen for test3
command: uuidgen
run_once: true
delegate_to: localhost
register: uuid
- name: run test3
run_test: name=test3 unique_id="{{ uuid.stdout_lines[0] }}"
But my idea was to simplify it and generate some id directly inside the
module (or probably reuse some internal ansible variable), so the final
playbook could look like this (and each test will have available unique
string common for all hosts):
- name: run test1
run_test: name=test1
- name: run test2
run_test: name=test2
- name: run test3
run_test: name=test3
I've tried to use method get_module_path() and parse the first number after
ansible-tmp-... in the path (it looks like
/root/.ansible/tmp/ansible-tmp-1423668579.15-197746855489444), but it seems
like it sometimes vary and it broke the synchronization.
Do you have any suggestion how to generate or where to obtain common id for
all hosts inside the ansible module (written in python)?
Thanks!
Daniel
