Using with_items with a dictionary

[Michael Bushey]

Hello,

I have a dict that contains a list of sites. For each of these sites I would like to provide a list of symlinks to create provided by with_items. Is this possible? I have Ansible 2.3.1.0.


Thanks!
Michael

I'm not quiet sure I understand your data model but instead of with_items have a look at with_dict.

Thanks for responding Uwe! I appreciate your time. :)

I'm already using a with_dict to get the list of sites, but now for each site I would like to provide a list of symlinks to generate. The list of symlinks does not change.

This creates the docroots:

- name: Create docroot
  file: path=/var/www/html/{{ item.value.url }} state=directory owner=www-data group=www-data
  with_dict: "{{ sites }}"
  when: item.value.type == "grav"
  tags: grav, grav-sites

I would like to create the same symlinks for each of these sites, but I don't know how to get {{ site from dict }}:

- name: Create symlinks
  file: dest=/var/www/html/{{ site from dict }}/{{ item }} src=/var/www/grav/grav/{{ item }} state=link owner=www-data group=www-data
  with_items:
    - bin
    - CHANGELOG.md
    - composer.json
    - .editorconfig
    - .gitignore
    - index.php
    - LICENSE.txt
    - system
    - vendor
  tags: grav, grav-sites

My first thought was to put those two tasks into a block, modify task 1 to register a new variable that contains the current site
and use it in task 2. Then I remembered that you cannot loop over a block (currently…
https://github.com/ansible/ansible/issues/13262).


You could try to create a new list variable out of your dict which only contains all {{ site from dict }} and then use
with_nested. E.g.

- name: 'create docroot'
...

- name: 'extract sites'
set_fact: sitenames='{{ sitenames | default([]) }} + {{ item.name }}'
with_dict: '{{ sites }}'

- name: 'create symlinks'
file:
dest: '/var/www/html/{{ item[0] }}/{{ item[1] }}'
src: '/var/www/grav/grav/{{ item[1] }}'
state: link
owner: www-data
group: www-data
with_nested:
- '{{ sitenames }}'
- [ 'bin', 'CHANGELOG.md', ...]

Hi Michael, This simple example might help you that how we can use the with_items with dictionary:

---
- hosts: all
  become: no
  gather_facts: no
  connection: local
  vars:
    USERS:
      foo:
        state: present
        company: 'Bar foo'
        email: foo@test.net
        uid: 6001
        groups:
          - ring-admins
          - ring-users
     
      bar:
        state: present
        company: 'Foo bar'
        email: bar@tlt.com      
        uid: 6002
        groups:
          - ring-admins
          - ring-users


  tasks:
    - debug:
        msg: "{{ item }} , {{ USERS[item].state }} , {{ USERS[item].company }}, {{ USERS[item].email }}, {{ USERS[item].uid }} , {{ USERS[item].groups|join( ',' ) }}"
      with_items: "{{ USERS | list }}"

Result of the playbook:

╰─➤  ansible-playbook -i localhost, playbook.yml

PLAY [all] *******************************************************************************************************************

TASK [debug] *****************************************************************************************************************

ok: [localhost] => (item=foo) => {

    "item": "foo",

    "msg": "foo , present , Bar foo, f...@test.net, 6001 , ring-admins,ring-users"

}

ok: [localhost] => (item=bar) => {

    "item": "bar",

    "msg": "bar , present , Foo bar, b...@tlt.com, 6002 , ring-admins,ring-users"

}

PLAY RECAP *******************************************************************************************************************

localhost                  : ok=1    changed=0    unreachable=0    failed=0

Hope that might help you.
