Ansible : query an output array

[Z-obaze]

Hi everyone,

I'm wondering if there is a simple way to display the value of on exact item for each row whatever the number of entries we have ?

I'll explain myself, I have an ouput which looks like this :

ok: [server1] => {
    "requirements": {
        "changed": false,
        "msg": "All items completed",
        "results": [
            {
                "_ansible_item_result": true,
                "_ansible_no_log": false,
                "_ansible_parsed": true,
                "changed": false,
                "invocation": {
                    "module_args": {
                        "conf_file": null,
                        "disable_gpg_check": false,
                        "disablerepo": null,
                        "enablerepo": null,
                        "exclude": null,
                        "install_repoquery": true,
                        "list": "first_package",
                        "name": null,
                        "state": "installed",
                        "update_cache": false,
                        "validate_certs": true
                    },
                    "module_name": "yum"
                },
                "item": "first_package",
                "results": [
                    {
                        "arch": "x86_64",
                        "epoch": "0",
                        "name": "name_of_the_package",
                        "nevra": "0:first_package",
                        "release": "release_of_the_package",
                        "repo": "repo",
                        "version": "version_of_the_package",
                        "yumstate": "available"
                    }
                ]
            },
            {
                "_ansible_item_result": true,
                "_ansible_no_log": false,
                "_ansible_parsed": true,
                "changed": false,
                "invocation": {
                    "module_args": {
                        "conf_file": null,
                        "disable_gpg_check": false,
                        "disablerepo": null,
                        "enablerepo": null,
                        "exclude": null,
                        "install_repoquery": true,
                        "list": "second_package",
                        "name": null,    
                        "state": "installed",
                        "update_cache": false,
                        "validate_certs": true
                    },
                    "module_name": "yum"
                },
                "item": "second_package",
                "results": [
                    {
                        "arch": "x86_64",
                        "epoch": "0",
                        "name": "name_of_the_package",
                        "nevra": "0:second_package",
                        "release": "release_of_the_package",
                        "repo": "repo",
                        "version": "version_of_the_package",
                        "yumstate": "available"
                    }
                 ]

And with that output, i'd like to display the value of "yumstate" entry for all of the items, here we have two items, but we could have 3, 4 or more.

Within my playbook i tried to do something like this, but of course it doesn't work :

        - name: debug
          debug:
             var: 'requirements.results[*].results[*].yumstate'

I also tried with a loop, but I haven't found anything.

So does anyone have a clue to do this?

Thanks for your help

- debug: var=item.results.0.yumstate
with_items: "{{ requirements.results }}"

Thanks a lot, it was just what I needed.

Hi,

I'm finally stuck with another case.

Sometimes I could get something like this :

                        "repo": "installed",
                        "version": "version_of_the_package",
                        "yumstate": "installed"

So here, I have two results for the same package.
With the tip you gave me, I can only look into the first one, I know I could add "item.results.1.yumstate" but I don't want to cause I could get more than 2 results.

I tried with the "with_subelements" but it split the array by the number of results I have and in that case I want to compare "item.results.0.yumstate" and "item.results.1.yumstate"? But as I said I could get more.

Thanks for your help

To do this you need a loop in a loop.

Put the inner most loop in a yaml file and use include with with_itmes
to loop the outer item and use loop_control to change the variable name.
https://docs.ansible.com/ansible/playbooks_loops.html#loop-control

Thanks.

And is there a way to not use include and to keep the inner loop into the same playbook than the outer loop?
Cause I don't like the way it splits the playbook into two yaml files.

No, that is the only way to do it in Ansible.

If you are only using the data in a template then you can do loop in a
loop in Jinja2.

OK thanks.

And do you know if there is a way with the yum module to not have those two entries when the latest package is installed ? I'd like to have only the one with "yumstate=installed" and not the one with available state.
Cause actually I just want to know if one package is installed or not, but I don't want to install it, just check, that's why I don't want to use the "state=installed" or even "present" cause it will install the package if it's not here.
I tried a lot of thing but so far didn't find what I wanted.
does it make sense?

Thanks
