loops - ansible: how to iterate over all registered results? -

-

given following playbook:

--- - name: check if log directory exists - step 1   stat: path="{{ wl_base }}/{{ item.0.name }}/{{ wl_dom }}/servers/{{ item.1 }}/logs" get_md5=no   register: log_dir   with_subelements:     - wl_instances     - servers  - name: check if log directory exists - step 2   fail: msg="log directory not exists or not symlink."   failed_when: >     log_dir.results[0].stat.islnk not defined     or log_dir.results[0].stat.islnk != true     or log_dir.results[0].stat.lnk_source != "{{ wl_base }}/logs/{{ wl_dom }}/{{ item.1 }}"   with_subelements:     - wl_instances     - servers

that using following vars:

--- wl_instances:   - name: aservers     servers:       - adminserver   - name: mservers     servers:        - "{{ ansible_hostname }}"

the second task uses 1 of 2 possible results (results[0]).

my question is: how iterate on available items stored in log_dir.results?

a sample output debug:hostvars[inventory_hostname] follows:

    "log_dir": {         "changed": false,         "msg": "all items completed",         "results": [             {                 "changed": false,                 "invocation": {                     "module_args": "path=\"/path/to/servers/aservers/domain/adminserver/logs\" get_md5=no",                     "module_name": "stat"                 },                 "item": [                     {                         "name": "aservers"                     },                     "adminserver"                 ],                 "stat": {                     ...                     "lnk_source": "/path/to/logs/domain/adminserver",                     ...                 }             },             {                 "changed": false,                 "invocation": {                     "module_args": "path=\"/path/to/servers/mservers/domain/servers/some_hostname/logs\" get_md5=no",                     "module_name": "stat"                 },                 "item": [                     {                         "name": "mservers"                     },                     "some_hostname"                 ],                 "stat": {                     ...                     "lnk_source": "/path/to/logs/domain/some_hostname",                     ...

looping on results in array (denoted []), done as

with_items: somelist

or if it's dict contains list, in case

with_items: log_dir.results

note can written

with_items: log_dir['results']

so in task

- name: check if log directory exists - step 2   fail: msg="log directory not exists or not symlink."   failed_when: >     item.stat.islnk not defined     or item.stat.islnk != true     or item..stat.lnk_source != "{{ wl_base }}/logs/{{ wl_dom }}/{{ item.1 }}"   with_items: log_dir.results

more information , examples available in http://docs.ansible.com/playbooks_loops.html#standard-loops.

the main thing here you're wanting access part of registered variable.
