remove files from host that are not in a dictionary

[mekonh...@gmail.com]

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

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 :

{"msg": "All items completed", "changed": true, "results": [{"_ansible_parsed": true, "changed": true, "stdout": "vhost02.conf", "_ansible_item_result": true, "warnings": [], "delta": "0:00:00.002037", "stdout_lines": ["vhost02.conf"], "end": "2017-01-10 12:14:06.090689", "_ansible_no_log": false, "start": "2017-01-10 12:14:06.088652", "cmd": "echo \"vhost02.conf\"", "item": {"key": "vhost02", "value": {"servername": "vhost02", "domain": "company.com"}}, "stderr": "", "rc": 0, "invocation": {"module_name": "command", "module_args": {"warn": true, "executable": null, "_uses_shell": true, "_raw_params": "echo \"vhost02.conf\"", "removes": null, "creates": null, "chdir": null}}}, {"_ansible_parsed": true, "changed": true, "stdout": "vhost01.conf", "_ansible_item_result": true, "warnings": [], "delta": "0:00:00.002117", "stdout_lines": ["vhost01.conf"], "end": "2017-01-10 12:14:06.253953", "_ansible_no_log": false, "start": "2017-01-10 12:14:06.251836", "cmd": "echo \"vhost01.conf\"", "item": {"key": "vhost01", "value": {"servername": "vhost01", "domain": "company.com"}}, "stderr": "", "rc": 0, "invocation": {"module_name": "command", "module_args": {"warn": true, "executable": null, "_uses_shell": true, "_raw_params": "echo \"vhost01.conf\"", "removes": null, "creates": null, "chdir": null}}}]}

Here is the output of vhost_config_files :

{"start": "2017-01-10 12:14:06.895256", "delta": "0:00:00.002718", "cmd": "ls -1 \"/etc/nginx/conf.d\"", "end": "2017-01-10 12:14:06.897974", "stderr": "", "stdout": "dummy.conf\nvhost01.conf\nvhost02.conf\nvhost03.conf", "stdout_lines": ["dummy.conf", "vhost01.conf", "vhost02.conf", "vhost03.conf"], "changed": true, "rc": 0, "warnings": []}

I would expect it to remove dummy.conf and vhost03.conf from the host.

Any help on how to do this would be greatly appreciated.

I am running Ansible version 2.2.0.0

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.

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.
