Loop through the contents of include_vars file via a shell module

[Saranya N]

I want to replicate a shell script that loops through the contents of a text.file
For i in `cat text.file`

I tried below and got an error.
I'm not getting which logic to use. Kindly advise.

- name: Load the variables

include_vars:

file: /home/devuser/internproj/inventories/NP/voblist.yml

register: dits_list

- debug:

msg: "{{ dits_list.ansible_facts }}"

- name: run the tool commands

shell: /usr/atria/bin/sertool -load -host aaa {{ items }} {{ items }}

args:

chdir: "/home/vobadmin"

with_items: "{{ vob_list.dits }}" #How to achieve this part?

I want to pass the contents of the voblist to the shell module to excute the above shell command.

Basically I want to replicate the below shell script

For i in `cat /home/devuser/internproj/inventories/NP/voblist.yml`

Do

/usr/atria/bin/sertool -load -host aaa $i $i

Done

if

===========================================================================================================

cat /home/devuser/internproj/inventories/NP/voblist.yml

---

dits:

- /project/vob_solaris_test.vbs

- /project/vob_solaris_test2.vbs

include_vars read the variable inside the file and make them available
for Ansible so no need for the register.

- name: run the tool commands

shell: /usr/atria/bin/sertool -load -host aaa {{ item }} {{ item }}
args:
chdir: "/home/vobadmin"
with_items: "{{ dits }}"

That for loop doesn't make sense with that file.
On fist loop it would contain "---", and the second it would contain
"dist:" and third "- /project/vob_solaris_test.vbs".

Hi Kai ,

Thankyou for your response but unfortunately it still doesn't work for me.

It still doesn’t work. Sorry, I’m very new to ansible and just started working on it.



I get below error:



task path: /home/dev_user/ansible_test/ansible_dev/clearcase/playbooks/testdump.yml:20

ok: [aaa.com] => {

"ansible_facts": {

"localvar": {

"vobs": [

"/project/vob_solaris_test.vbs",

"/project/vob_solaris_test22.vbs"

]

}

},

"changed": false

}



TASK [lsvob] **************************************************************************************************************************************************************************************************

}

to retry, use: --limit @/home/dev_user/ansible_test/ansible_dev/clearcase/playbooks/testdump.retry



PLAY RECAP ***************************************************************************************************************************

aaa.com : ok=3 changed=2 unreachable=0 failed=1









my playbook lokks like below:

---

- hosts: sol

become: yes

become_method: su

become_user: vobadmin

gather_facts: no



tasks:

- name: Load the variables

include_vars:

file: /home/a594588/ansible_test/ansible_dev/clearcase/inventories/NP/voblist.yml

name: localvar



- name: lsvob

shell: /usr/atria/bin/cleartool lsvob | grep -i {{ items }}

args:

chdir: "/home/vobadmin"

with_items: "{{ dits }}"





I changed the contents of the include_vars file input file:



cat /home/devuser/internproj/inventories/NP/voblist.yml



dits:



- /project/vob_solaris_test.vbs

- /project/vob_solaris_test22.vbs

[Karl Auer]

I'm new to Ansible too, so take this explanation with a grain of salt!

My understanding of "with_items" is that it takes a list. The loop iterates over the list, referring to the current element as "item".

So inside your loop, you should refer to "item" (not "items"!)) which on each iteration will be replaced by the next element from the list called "dits".

Something like this:

- name: lsvob
    shell: /usr/atria/bin/cleartool lsvob | grep -i {{ item }}

    args:
      chdir: "/home/vobadmin"
    with_items: "{{ dits }}"

I'm not sure what that shell command is doing, so can't comment on whether it is correct for your purpose.

Regards, K.

Hi Karl,

The shell command is for a tool.
But the logic I'm trying to execute is very simple.
List all the files such that the files' names contains the words present in dits list which I'm sending via the include_vars file.

I'm seriously not understanding whats going wrong here.

I get dits is not defined error like below.

task path: /home/devuser/ansible_test/ansible_dev/clearcase/playbooks/simple.yml:15

fatal: [aaa.com]: FAILED! => {

"failed": true,

"msg": "'dits' is undefined"

}

to retry, use: --limit @/home/devuser/ansible_test/ansible_dev/clearcase/playbooks/simple.retry

PLAY RECAP ****************************************************************************************************************************************************************************************************

- hosts: sol

become: yes

become_method: su

become_user: vobadmin

gather_facts: no

tasks:

- name: Load the variables

include_vars:

file: /home/devuser/ansible_test/ansible_dev/clearcase/inventories/NP/voblist.yml

name: localvar

- name: List id

shell: ls -ltr | grep -i {{ item }}

register: shell_op

with_items: "{{ dits }}"

- debug:

msg: "{{ localvar.dits }}"

cat /home/devuser/internproj/inventories/NP/voblist.yml

dits:

- aaa

- bbb

[Karl Auer]

The file you refer to in your playbook is:

/home/devuser/ansible_test/ansible_dev/clearcase/inventories/NP/voblist.yml

The file containing the dits variable is:

/home/devuser/internproj/inventories/NP/voblist.yml

Could that be the problem?

Regards, K.

Sorry that's a typo .

The location in playbook and the actual file is same.

[Saranya N]

I got this working

Since dits is a list I had to use like below.

With_items: "{{ dits | list }}"

It's impotent to pay attention to the details.

That's because it doesn't exist, I explain bellow.

Here you say, take the variables in voblist.yml and put them is the
variable localvar.
This you did not have in you first post.

So you then need to use localvar.dits

You did it here so it's important to go over the entire code when you
changes things.

To me it looks like you are changing too many things at the same time,
and because of that makes bugs in your code.
