'messaging/rabbitmq_policy' fails to set up policy parameters requiring integer as the input

[Huaxing Sun]

I keep getting error with the following ansible command.

...
- name: create policy

  rabbitmq_policy:

    name={{ item.name }}

    vhost={{ item.vhost | default('/', false) }}

    pattern={{ item.pattern }}

    priority={{ item.priority }}

    tags={{ item.tags }}

  with_items: rabbitmq_policy_configuration
...

where 'rabbitmq_policy_configuration' is

rabbitmq_policy_configuration
-name: GLOBAL
  vhost: /
  pattern: .*
  priority: 0
  tags: ha-mode=all,ha-sync-mode=automatic,max-length=1000000,expires=1296000000

When the module processes this configuration, the value of 'tags' is converted strictly to a string.

But in fact, the values of 'max-length' and 'expires' must be ints for rabbitmqctl(assuming people understand what rabbitmqctl does) to work properly.

This is the error message

failed: [10.*.*.*] => (item={'priority': 0, 'vhost': '/', 'tags': 'ha-mode=all,ha-sync-mode=automatic,max-length=1000000,expires=1296000000', 'name': 'GLOBAL', 'pattern': '.*'}) => {"cmd": "/usr/sbin/rabbitmqctl -q -n rabbit set_policy -p / GLOBAL '.*' '{\"ha-sync-mode\": \"automatic\", \"expires\": \"1296000000\", \"ha-mode\": \"all\", \"max-length\": \"1000000\"}' --priority 0", "failed": true, "item": {"name": "GLOBAL", "pattern": ".*", "priority": 0, "tags": "ha-mode=all,ha-sync-mode=automatic,max-length=1000000,expires=1296000000", "vhost": "/"}, "rc": 2}

stderr: Error: Validation failed

<<"1296000000">> is not a valid queue expiry

msg: Error: Validation failed

According to ansible docs, 'tags' can be a dictionary so I tried with this

rabbitmq_policy_configuration:
- name: GLOBAL
  vhost: /
  pattern: .*
  priority: 0
  tags:
     ha-mode: all
     ha-sync-mode: automatic
     max-length: 1000000
     expires: 1296000000

But it did not prevail.

 

failed: [10.*.*.*] => (item={'priority': 0, 'vhost': '/', 'tags': {'ha-sync-mode': 'automatic', 'expires': 1296000000, 'ha-mode': 'all', 'max-length': 1000000}, 'name': 'GLOBAL', 'pattern': '.*'}) => {"failed": true, "item": {"name": "GLOBAL", "pattern": ".*", "priority": 0, "tags": {"expires": 1296000000, "ha-mode": "all", "ha-sync-mode": "automatic", "max-length": 1000000}, "vhost": "/"}}
msg: this module requires key=value arguments (['name=GLOBAL', 'vhost=/', 'pattern=.*', 'priority=0', 'tags={ha-sync-mode:', 'automatic,', 'expires:', '1296000000,', 'ha-mode:', 'all,', 'max-length:', '1000000}'])


FATAL: all hosts have already failed -- aborting

Could anyone please help pointing out what I have done wrong? I read the source of rabbitmq_policy on github and did not spot any type conversions of individual parameter values belong to the argument of 'tags'. I am starting to doubt there is a bug.

FYI these are the environment information

Ansible version: 1.7.2-1ppa~precise

PC environment: Ubuntu 12.04

Hi Huaxing,

This appears to be a simple formatting error. In your first example, you are mixing up the "complex argument" form (where everything is formatted as a dictionary in the YAML) but are specifying the tags as a comma separated list. You should be using the dictionary format for YAML for this instead:

  tags: 
    ha-mode: all
    ha-sync-mode: automatic

    max-length: 1000000

    expires: 1296000000

And rather than using the k=v format for your task, you should be using the complex form:

- name: create policy

  rabbitmq_policy:

    name: "{{ item.name }}"

    vhost: "{{ item.vhost | default('/', false) }}"

    pattern: "{{ item.pattern }}"

    priority: "{{ item.priority }}"

    tags: "{{ item.tags }}"

  with_items: rabbitmq_policy_configuration

Let us know if this doesn't get you past the error.

Thanks!

James, thank you for the quick reply. Your advice fixed my problem. Complex form it is!!!
