Variables with quotes

[Shaun Lim]

Hi all,

I'm new to Ansible and am trying to use some variables with quotes. The command I'm trying to run is as follows:

rabbitmqctl set_permissions -p /vhost username ".*" ".*" ".*"

To do this, I'm trying to use the command module. If I include the command exactly as above, the command runs successfully but I'm trying to make this reusable so I've changed a few of those into variables instead. My task currently looks like this:

- name: Set user permissions on RabbitMQ
  become: yes
  command: rabbitmqctl set_permissions -p /"{{ rabbitVhost }}" "{{ rabbitUser }}" "{{ rabbitAcl }}"

I can't seem to get this to work. I've tried sending the parameters like this:

ansible-playbook rabbit.yml --extra-vars='{"rabbitUser":"shaun","rabbitSecret":"P@ssw0rd","rabbitVhost":"sensu","rabbitAcl":"\\\".*\\\" \\\".*\\\" \\\".*\\\""}'

The error I get is as below and it looks like the parameters are being set correctly:

fatal: [localhost]: FAILED! => {
    "changed": true,
    "cmd": [
        "rabbitmqctl",
        "set_permissions",
        "-p",

        "\".*\" \".*\" \".*\""
    ],

            "executable": null,

            "stdin": null,
            "warn": true
        }
    },
    "msg": "non-zero return code",
    "rc": 64,

    "stderr_lines": [
        "Error: operation set_permissions used with invalid parameter: [\"shaun\",",
        "                                                               \"\\\".*\\\" \\\".*\\\" \\\".*\\\"\"]"
    ],

Any help would be appreciated.

Thanks.

Try to use the Ansible rabbitmq_user module as this will be much easier to accomplish your needs.

Thanks for the tip Larry.

I wanted to create my own module as I am learning Ansible.

In any case, I managed to get it done by splitting each type of permission into its own variable. I think a combined string with too many quotes caused some parsing issues.

Absolutely and completely understand.

Good luck with your learning.
