I am getting below error (/bin/sh: nslookup: command not found ) when i am using vagrant for ansible code testing using molecule testig
TASK [Query nslookup own domain] ***********************************************

so it seems nslookup is not installed
You can add a task to install the necessary tools
- name: Install nslookup
apt:
name: dnsutils
state: present
If you are on red-hat distro you need following package
- name: Install nslookup
yum:
name: bind-utils
state: present
or if you want to distribute any bistro you can add both
- name: Install nslookup for ubuntu
apt:
name: dnsutils
state: present
when: ansible_os_family == 'Debian'
- name: Install nslookup for redhat family
yum:
name: bind-utils
state: present
when: ansible_os_family == 'RedHat'
I have to execute below 2 commands whose value depends on the system.
# sysctl -w kernel.shmmax= parse_from_shm.sh script #For example 17179869184
# sysctl -w kernel.shmall= parse_from_shm.sh script #For example 4194304
./shm.sh will echo both system values required in the below format
kernel.shmmax=4185686016
kernel.shmall=1021896
So I have to parse & get integer value above result & execute ultimately below 2 commands
# sysctl -w kernel.shmmax=4185686016
# sysctl -w kernel.shmall=1021896
I have tried to register & parse the integer values using regex. But I couldn't able to process it perfectly. Any help would be of great help.

As you can very clearly see in the set_fact results dict, the output of regexp_search is a list of matched strings, not the just the capture group. And, because your regex is imprecise, that's why your shmmax is the numbers plus a newline plus the rest of the text.
The accurate regex is shmmax=([0-9]+) because those values aren't "any character except a double quote" it's "any number after the equals sign"

I have written the following ansible playbook to find the disk failure on the raid
- name: checking raid status
shell: "cat /proc/mdstat | grep nvme"
register: "array_check"
- debug:
msg: "{{ array_check.stdout_lines }}"
Following is the output I got
"msg": [
"md0 : active raid1 nvme0n1p1[0] nvme1n1p1[1]",
"md2 : active raid1 nvme1n1p3[1](F) nvme0n1p3[0]",
"md1 : active raid1 nvme1n1p2[1] nvme0n1p2[0]"
]
I want to extract the disk name which is failed from the register variable array_check.
How do I do this in the ansible? Can I use set_fact module in ansible? Can I use grep, awk, sed command on the register variable array_check
This is the playbook I am using to check the health status of a drive using smartctl

Change the indent like below and remove ignore_errors.
