Question

Trying to create a partition and mountpoint on the Azure Disks, which are getting attached to VM on creation as part of terraform. Disks should be created based on user input through Jenkins.
Each disk was passed with a LUN number and I am fetching the device name(sdc,sdd etc.) for each disk using that LUN number and grep. In my_tasks.yml this tasks to be looped with include_tasks in playbook.yml as below:
my_tasks.yml
---
- parted:
device: "{{ volumename.stdout }}"
number: 1
state: present
- filesystem:
fstype: xfs
dev: "{{ volumename.stdout }}"
- mount:
fstype: xfs
opts: noatime
src: "{{ volumename.stdout }}"
path: "{{ item.mountpoint }}"
state: mounted
- command: blkid -s UUID -o value {{ volumename.stdout }}
register: volumename_disk
- blockinfile:
path: /etc/fstab
state: present
block: |
UUID={{ volumename_disk.stdout }} {{ volumename.stdout }} xfs defaults,noatime,nofail 0 0
playbook.yml
---
- hosts: "{{ host }}"
become: true
become_method: sudo
become_user: root
vars:
mount: "{{ lookup('file', '/home/xyz/vars.txt') }}"
tasks:
- name: Generate the Lun_Name
shell: "tree /dev/disk/azure/scsi1 | grep -i lun | awk '{print $2}'"
register: lun
- set_fact:
lun_name: "{{ lun_name|default([]) + [ { 'name': lun.stdout } ] }}"
- debug:
msg: "LUN is: {{ lun_name }}"
- name: Generate the Volume_Name
shell: echo "$(ls -l /dev/disk/azure/scsi1 |grep lun |egrep -o "([^\/]+$)")"
register: volumename
- set_fact:
volumenames: "{{ volumenames|default([]) + [ { 'name': volumename.stdout } ] }}"
- debug:
msg: "VOLUMENAME is: {{ volumenames }}"
# - debug:
# msg: "the mountpoints are {{ mount }}"
- set_fact:
mountpoint: "{{ lookup('file', '/home/xyz/vars.txt').split(',') }}"
- debug:
msg: "the mountpoints are {{ mountpoint }}"
# loop: "{{ mountpoint }}"
- include_tasks: my_tasks.yml
loop: "{{ item.volumenames | list }} {{ item.mountpoint | list }}"
loop_control:
loop_var: "{{ item }}"
fatal: [10.102.26.74]: FAILED! => {"msg": "'item' is undefined"}
Issue seems to be with loop inside a include_tasks, I'm able to get the loop working for mountpoint which is running after set_fact in playbook.yml
How can I resolve this issue or improve the code?
