'delegate_to' is not a valid attribute for a TaskInclude

@mattymo any ideas on how to solve this?

[cwpenhale]

Hey, I'm running into this as well. I'm on the Ansible 2.8.0rc1 because I needed 'use_contrib_script_compatible_sanitization' fix for the GCP dynamic inventory plugin. Is this a known issue, are there other people running into this?

[rhockenbury]

Hit this today w/ 2.8.0rc2. This is the expected beahavior of 2.8 according to this - ansible/ansible#56072

[electrocucaracha]

It seems like INVALID_TASK_ATTRIBUTE_FAILED default value has been changed to True. Maybe I quick workaround could be its default value until it's change in ansible.

export ANSIBLE_INVALID_TASK_ATTRIBUTE_FAILED=False

[rhockenbury]

Yes, I believe I ended up setting that, but got hung up on a handful of other errors I encountered further along when using the 2.8 rc, and eventually gave up. Would be interested to hear if anyone has successfully deployed Kubespray with Ansible2.8

@rhockenbury I did it. I have submitted the PR to disable that feature, in the meantime you can use the workaround that I mentioned disabling ANSIBLE_INVALID_TASK_ATTRIBUTE_FAILED thru a environment variable.

[rhockenbury]

I'm hitting this w/ ansible 2.8:

TASK [download : kubeadm | Copy kubeadm binary from download dir] *********************************************************************************************************************************************************

@electrocucaracha Did you run into this?

[electrocucaracha]

@rhockenbury it seems like you're running kubespray in Ubuntu distro. What I do is to install sshpass before its execution.

[karthik101]

On some environments passing the variable didnt do any effect so i had to add the below in ansible.cfg file in kubespray folder.

[defaults]
invalid_task_attribute_failed=False

[woopstar]

Ansible 2.8 is not supported yet

[houming818]

can I downgrade to any version of ansible?

[electrocucaracha]

can I downgrade to any version of ansible?

@stduolc according to the documentation you should use v2.7.8

[rushins]

i hit the same error today

ERROR! 'delegate_to' is not a valid attribute for a TaskInclude

The error appears to be in '/root/kubespray/roles/network_plugin/calico/tasks/main.yml': line 6, column 3, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

• include_tasks: upgrade.yml

BR,
Rushi.

[nf123git]

The problem is this:

1. I can use import_tasks with delegate_to
2. I cannot use import_tasks with a loop - it says:
   You cannot use loops on 'import_tasks' statements. You should use 'include_tasks' instead.
3. I cannot use delegate_to, with include_tasks, because I hit this issue:
   'delegate_to' is not a valid attribute for a TaskInclude

So... once again, Ansible makes it impossible to do something that should be incredibly simple.

Found a workaround for 3. at least.
Just wrap the include_tasks in a block. and put the delegate at the block level.

e.g.

- include_tasks: inc.yml
  delegate_to: host1

change to:

- block:
    - include_tasks: inc.yml
  delegate_to: host1

This post may help:

The solution, explained

Input:
We can not use loop with import, we need to use include.
We can not use delegate to with include, we need to use import.
Solution:
We use loop + include_tasks to run a separate tasklist.
2. We use import_role + delegate_to to delegate a role to another host.

[techcloudim]

This is expected behaviour in Ansible 2.8. ansible/ansible#56072

you need to follow below syntax

- name: Setting up xxxx
   include_tasks: xxxx.yml
   args:
     apply:
         delegate_to: 127.0.0.1
   with_items:
     - "{{ plugins_loop }}"
   run_once: true
