with_sequence: / with_items: question

[Jimmy Prescott]

I am probably have my syntax wrong but I am trying to reduce the amount of code in my playbook when creating cloud block storage volumes using rax_cbs. Here is what it looks like currently and works great:

- name: Build a Block Storage Volume
  gather_facts: False
  hosts: localhost
  connection: local
  tasks:
    - name: Create glustor1
      local_action:
        module: rax_cbs
        name: glustor1
        description: brick2
        volume_type: SATA
        size: 100
        region: DFW
        wait: yes
        state: present
        meta:
          app: glustor1
      register: raxvolumes
    - name: Create glustor2
      local_action:
        module: rax_cbs
        name: glustor2
        description: brick2
        volume_type: SATA
        size: 100
        region: DFW
        wait: yes
        state: present
        meta:
          app: glustor2
      register: raxvolumes
    - name: Create glustor3
      local_action:
        module: rax_cbs
        name: glustor3
        description: brick3
        volume_type: SATA
        size: 100
        region: DFW
        wait: yes
        state: present
        meta:
          app: glustor3
      register: raxvolumes
    - name: Create glustor4
      local_action:
        module: rax_cbs
        name: glustor4
        description: brick4
        volume_type: SATA
        size: 100
        region: DFW
        wait: yes
        state: present
        meta:
          app: glustor4
      register: raxvolumes

And I have tried the following based on http://docs.ansible.com/playbooks_loops.html but it errors due to item not being defined:

- name: Build a Block Storage Volume # I also tried changing {{ item }} to {{ format }}
  gather_facts: False
  hosts: localhost
  connection: local
  tasks:
    - name: Create glustor bricks
      local_action:
        module: rax_cbs
        name: "{{ item }}"
        description: Glustor Brick
        volume_type: SATA
        size: 100
        region: DFW
        wait: yes
        state: present
        with_sequence: start=1 end=4 format=glustor%d
      register: raxvolumes

TASK: [Create glustor bricks] *************************************************
fatal: [localhost] => One or more undefined variables: 'item' is undefined

FATAL: all hosts have already failed -- aborting

Also tried the following:

- name: Build a Block Storage Volume
  gather_facts: False
  hosts: localhost
  connection: local
  tasks:
    - name: Create glustor bricks
      local_action:
        module: rax_cbs
        name: "{{ item }}"
        description: Glustor Brick
        volume_type: SATA
        size: 100
        region: DFW
        wait: yes
        state: present
        with_items:
          - glustor1
          - glustor2
          - glustor3
          - glustor4
      register: raxvolumes

TASK: [Create glustor bricks] *************************************************
fatal: [localhost] => One or more undefined variables: 'item' is undefined

FATAL: all hosts have already failed -- aborting

Thanks for pointing me in the right direction!

Your with_items or with_sequence is indented too far.  It should match the indentation of "register" and "name".

Also be aware of how register and with_ works. There are some docs on the playbooks loops page in the docs.
