ignore_errors does not take variable

[Yasir Saleem]

Hi,

   I was trying to use ignore_errors to take a variable, but it fails.

Here is example play for ignore error not working:

- hosts: jump

  remote_user: deploy

  gather_facts: yes

  tasks:

    - set_fact: test_err=yes

    - debug: var=test_err

      ignore_errors: "{{ test_err }}"

output was:

#############

    raise self._undefined_exception(hint)

When I use a static value, 'yes' it works:

- hosts: jump

  remote_user: deploy

  gather_facts: yes

  tasks:

    - set_fact: test_err=yes

    - debug: var=test_err

      ignore_errors: yes

output was:

Isn't this a bug? 

I am using ansible 1.7.1 release

Thanks,

Yasir.

Hi Yasir,

Have you read through: http://docs.ansible.com/playbooks_error_handling.html  ?

Ignore_errors is taking yes or no, because simply put there isn't any other answer possible to "Do you want me to ignore the errors?" yes/no. You are answering with "Mooo" and the system doesnt speak cowish, yet

I'm interested in knowing why do you want to let ignore_errors take a variable?

Regards,

Mark

I am setting test_err to 'yes' via set_fact:

below is playbook details:

######

- hosts: jump

  remote_user: deploy

  gather_facts: yes

  tasks:

    - set_fact: test_err=yes

    - debug: var=test_err

    - debug: var=test_err

      ignore_errors: "{{ test_err }}"

####

output of above playbook:

########

Reason we are trying to use ignore_errors via variable is because we are using our own module to run 'cucumber' tests in a role, we want to give control via variable weather to stop execution upon failures to the role user. Because in case tests are run in CI ( via jenkins) we want jenkins plugin to compile results, for command line users, ansible console we will have control.

I hope this clarifies.

Thanks,

Yasir.

You are setting test_err to the *string* yes, but ingore_errors is
looking for a boolean expression. Also, you don't need to using the
"{{ }}" syntax in ignore_errors since it is already using jinja2. Try
using the "bool" filter:

- hosts: jump
remote_user: deploy
gather_facts: yes
tasks:
- set_fact: test_err=yes
- debug: var=test_err

ignore_errors: test_err | bool

I tried few combinations:

#####

- hosts: jump

  remote_user: deploy

  gather_facts: yes

  tasks:

    - set_fact: test_err=yes

    - debug: var=test_err

    - debug: var=test_err

      ignore_errors: test_err | bool 

#####

or 

####

- hosts: jump

  remote_user: deploy

  gather_facts: yes

  tasks:

    - set_fact: test_err={{ 'yes' |bool }}

    - debug: var=test_err

    - debug: var=test_err

      ignore_errors: test_err 

####

or 

####

- hosts: jump

  remote_user: deploy

  gather_facts: yes

  tasks:

    - set_fact: test_err=True

    - debug: var=test_err

    - debug: var=test_err

      ignore_errors: test_err

####

In all cases got following error:

####

PLAY [jump] ******************************************************************* 

GATHERING FACTS ***************************************************************

TASK: [set_fact test_err=True] ************************************************

ok: [qactld1-jump] => {

    "test_err": "True"

}

TASK: [debug var=test_err] **************************************************** 

ERROR: error while evaluating conditional: test_err

Hi,

This E-mail is a little bit old but I am in the same situation.

ignore_errors: test_err | bool

doesn't work for me on ansible 1.8.4

Is there any work around?

Thank you,

The last time I needed to have conditional ignore_errors, because that option did not accept a variable I had to duplicate the task in question. One version of the task had ignore_errors: yes and had a conditional when: my_var | bool and the other had no such setting and the conditional when: not my_var | bool.

Something like this:

vars:
  myvar: yes
tasks:
  - some_module: name=blah state=present
    ignore_errors: yes
    when: myvar | bool
  - some_module: name=blah state=present
    when: not myvar | bool

Hope this helps

Tom
