Can't filter Find togheter with with_sequence

[Cornelis van Ginkel]

Hi All,

I'm new here and have an issue that gives me a headache ;-)

I'm pretty new to ansible although I did the RH294 course.

Here's my playbook:

---

- name: count files and get oldest file

  hosts: all

  vars:

    - tomcat_home_dir: /data/tmp

    - folder_path: temp

  tasks:

    - name: Find how many tomcat instances we have

      find:

        paths: "{{ tomcat_home_dir }}"

        patterns: "tomcat*"

        recurse: no

        excludes: "tomcat"

        file_type: directory

      register: tmp_tomcat_dirs

    - name: debug

      debug:

        msg: "{{ tmp_tomcat_dirs.matched }}"

    - name: find files

      find:

        paths: "{{ tomcat_home_dir }}/tomcat{{ item }}/{{ folder_path }}"

        age: 90d

        recurse: yes

      with_sequence: start=1 end={{ tmp_tomcat_dirs.matched }}

      register: find_result

    - name: result

      debug:

         msg: "{{ find_result.matched }}"

which results in an error:

TASK [result] **************************************************************************************************************************************************************************************************

Thursday 25 March 2021  14:42:43 +0100 (0:00:02.455)       0:00:09.868 ********

fatal: [tstcgttoml01]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'dict object' has no attribute 'matched'\n\nThe error appears to have been in '/home/people/cginkel/automation_projects/playbooks/check_tmp_folder_tomcat/playbook.yml': line 30, column 7, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n    - name: result\n      ^ here\n"}

I understand the error, but why can't I use .matched all of a sudden?

If I run it without anything or just with .results it will give a list with all information about the files it finds. How do I get the attribute matched out of that?

here's an example list:

{

                "_ansible_ignore_errors": null,

                "_ansible_item_label": "3",

                "_ansible_item_result": true,

                "_ansible_no_log": false,

                "_ansible_parsed": true,

                "changed": false,

                "examined": 4,

                "failed": false,

                "files": [],

                "invocation": {

                    "module_args": {

                        "age": "90d",

                        "age_stamp": "mtime",

                        "contains": null,

                        "depth": null,

                        "excludes": null,

                        "file_type": "file",

                        "follow": false,

                        "get_checksum": false,

                        "hidden": false,

                        "paths": [

                            "/data/tmp/tomcat3/temp"

                        ],

                        "patterns": [

                            "*"

                        ],

                        "recurse": true,

                        "size": null,

                        "use_regex": false

                    }

                },

                "item": "3",

                "matched": 0,

                "msg": ""

Also, I am on version 2.6.6 and python 2.6.6 and can't use the map or selectattr filters.... which is a bummer, but it's a production machine I can't just upgrade.

The must be an easy way, but I spend hours reading the docs and forums.

Any help would be appreciated. If I can get around it without the with_sequence I would be glad to hear it on how to do this

With kind regards,

Cornelis

When using a loop your normal results are under a 'results' list, you
can still used matched, but now you have ONE per item in the mentioned
list:
debug:
msg: "{{ find_result.resuilts[0].matched }}"

^ will give you 'matched' for the first item

to get all matches:

debug: msg={{ find_result.results|map(attribute='matched')|list }}

^ will show matches per item in a list

change `list` for `sum` to get a total.
