I'm trying to remove config files from a host if they are no longer
managed
by ansible.
The ansible managed files are in a dictionary similar to the following
:
config_files:
vhost01:
servername: vhost01
domain: company.com
vhost02:
servername: vhost02
domain: company.com
And get added to the host as follows :
- name: Add ansible managed vhost config files.
template:
src: vhost.j2
dest: "{{ vhost_path }}/{{ item.key }}.conf"
mode: 0644
with_dict: "{{ config_files }}"
But when attempting to remove them with the following it does not work
:
- name: Build list of ansible managed files.
shell: echo "{{ item.key }}.conf"
with_dict: "{{ config_files }}"
register: managed_files
- name: Build list of config files on host.
shell: ls -1 "{{ vhost_path }}"
register: vhost_config_files
- name: Remove unmanaged vhost config files.
file:
path: "{{ vhost_path }}/{{ item }}"
state: absent
with_items: vhost_config_files.stdout_lines
when: item not in managed_files.stdout_lines
When you are using register and with_dict together, all the result will
be a list in managed_files.results, one item in the list for every
iteration.
So the managed_files.stdout_lines doesn't exist.
The error is as follows :
Unable to look up a name or access an attribute in template string ({%
if
item not in managed_files.stdout_lines %} True {% else %} False {%
endif %})
Here is the output of managed_files :

Here is the output of vhost_config_files :

I recommend using
- debug: var=managed_files
and
- debug: var=vhost_config_files
Then you get it in more human readable format, and you can easily the
structure of the variable.
