Ansible - roles and tasks execution handling in playbook

[Ankur Gupta]

I am working on ansible exception handling tasks and stuck in an ansible tasks execution handling problem where I need your guide to come over.

I have 2 system host group system_a and system_b and I develop 6 roles and each role have multiple tasks.I execute 2 roles on syste_a and reaming 4 on system_b.

in my case is, if any tasks in a role(1-6) are failed then skip the remains role execution and execution one task end of the playbook on system_a group host. 

How can handle this case in ansible.

Can you help me in this situation?

here is my site.yml

  - host: system_a

  roles:

      - role-1

      - role-2

- hosts: system_b

  roles:

      - role-3

      - role-4

      - role-5

      - role-6

- tasks:

      - name: restart postfix service

        service: name=postfix state=restarted           

        delegate_to: "{{ item }}"

        loop: "{{ groups['system_a'] }}"

Did you maybe try with serial and max_fail_percentage?

both serial and max_fail_percentage do not work for this case. because I need to skip the remaining roles.

Skipping the reminder roles/task is not a problem, that just a matter of
setting any_errors_fatal: true
The challenge is that you need to run a task afterword, but that is not
supported at that level(roles), you have it on task with block/rescue.
