How to caching Windows fact of ansible_fact to Redis? - ansible

Question

I have ansible_fact caching using redis.
It is well gathering to cache of redis for RHEL/AIX/HPUX and using ansible_fact of playbook.
but, Windows fact is not caching to redis.
What problem? or What configuration will do?
My ansible version is
[user]$ ansible --version
ansible 2.8.0
config file = /home/user/.ansible.cfg
configured module search path = [u'/home/user/utility/module']
ansible python module location = /usr/lib/python2.7/site-packages/ansible
executable location = /bin/ansible
python version = 2.7.5 (default, Mar 26 2019, 22:13:06) [GCC 4.8.5 20150623 (Red Hat 4.8.5-36)]
My ansible.cfg is
$ ansible-config dump --only-changed
ANSIBLE_PIPELINING(/home/user/.ansible.cfg) = True
CACHE_PLUGIN(/home/user/.ansible.cfg) = redis
CACHE_PLUGIN_CONNECTION(/home/user/.ansible.cfg) = localhost:6379:0
CACHE_PLUGIN_TIMEOUT(/home/user/.ansible.cfg) = 86100
DEFAULT_FACT_PATH(/home/user/.ansible.cfg) = /home/user/facts.d
DEFAULT_GATHERING(/home/user/.ansible.cfg) = smart
DEFAULT_REMOTE_USER(/home/user/.ansible.cfg) = user
First playbook is well done (gather_fact: yes), gathering ansible_memtotal_mb for windows
- name: gather fact
hosts: windows
gather_facts: yes
tasks:
- name: insertline
lineinfile
path: "fact.html"
insertbefore: "</th></tr>"
line: "{{ ansible_memtotal_mb }}"
Second playbook is problem (gather_fact: no), it is not use fact for cache data and fatal error occur.
- name: gather fact
hosts: windows
gather_facts: no
tasks:
- name: insertline
lineinfile
path: "fact.html"
insertbefore: "</th></tr>"
line: "{{ ansible_memtotal_mb }}"
The ansible_memtotal_mb is not using cache data of redis, despite of using cache for redis.
TASK [(lineinfile) Save result DATA to HTML file. ****************************

The error appears to be in '/home/user/systeminfo.yml': line 73, column 7, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
- name: (lineinfile) Save result DATA to HTML file. [\"{{ WEB_DIR }}\"]

We could be wrong, but this one looks like it might be an issue with
missing quotes. Always quote template expression brackets when they
start a value. For instance:
with_items:
- {{ foo }}
Should be written as:
with_items:
- \"{{ foo }}\"
"}
