Let's say that I have a role

# foo.yml
---
- name: A task
  tags: tag_A
  debug:
    msg: "A task"

- name: B task
  tags: tag_B
  debug:
    msg: "B task"

Now I want to create a playbook that will call the role foo, but only run the tag tag_B. I know that I can pass the --tags flag to the ansible-playbook command, but I want to do this every time and I don't want users to have to know to provide that flag? How do I call that role and only get the B_task task? I've tried

roles:
  - { role: 'foo', tags: 'tag_B' }

and

tasks:
  - include_role: foo
    tags: tag_B

But these just APPLY the tag to all of the tasks, it doesn't filter the tasks. I don't want to run all of the them, just the one.

Q: "Create a playbook that will call the role foo, but only run the tag tag_B."

A: It is not posible to declare TAGS_RUN and TAGS_SKIP inside a playbook. There are three options only that must be declared before a play starts

1. The environment variable. ANSIBLE_RUN_TAGS=tag_B

2. The configuration section [tags] run=tag_B

3. The option --tags ansible-playbook --tags tag_B pb.yml

In addition to this you can use Ansible Runner and put the tags into the file env/cmdline.
