I want to check the ip on the server where ip list i have in the json file as below,
cat /tmp/iplist.json
[
"10.10.10.182",
"182.10.10.2",
"192.168.200.2"
]
now the condition is only one ip exist on the system so i was executing the loop to store the only the success output in variable but i am not able to do that does any one knows how can i do this
here is my playbook
---
- name: Load values from json file
hosts: localhost
gather_facts: false
vars:
ip: "{{ lookup('file', '/tmp/iplist.json') | from_json }}"
tasks:
- name: Loop over imported iplist
shell: ip a | grep {{ item }}
loop: "{{ ip }}"
changed_when: true
register: echo
- debug:
msg: "{{ echo }}"
And this how it getting failed error

When you enable gather_facts: true the variable ansible_all_ipv4_addresses will keep the list of all IPv4 addresses of the host. Use intersect to find common items. For example
- debug:
msg: "{{ ansible_all_ipv4_addresses | intersect(ip) }}"
I am running a command to get the status of tomcat and registering it in a variable. How do i extract the specific output of that command and put it in a variable to check further
Play -
- name: Check the State og tomcat service
shell: "svcs tomcat"
register: tomcat_status
- name: Show captured processes
debug:
msg: "{{ tomcat_status.stdout_lines|list }}"
The output of the above is -
server1 ok: {
"changed": false,
"msg": [
"STATE STIME FMRI",
"online 20:11:48 svc:/network/tomcat:tomcat"
]
}
How do i extract the value of STATE here? I want to know if it's online or disabled or shutdown etc.
NOTE - Output with -vvvv
server1 done: {
"changed": true,
"cmd": "svcs tomcat",
"delta": "0:00:00.025711",
"end": "2020-05-11 12:43:43.323017",
"invocation": {

"stdout_lines": [
"STATE STIME FMRI",
"online 20:11:48 svc:/network/tomcat:tomcat"
]
}
Based on your debug about, tomcat_status.stdout_lines is a list (you don't need the |list filter here because it's already a list) that looks like:
["STATE STIME FMRI", "online 20:11:48 svc:/network/tomcat:tomcat"]
To get the STATE value, you need the first field from the second line. So:
- set_fact:
tomcat_state: "{{ tomcat_status.stdout_lines.1.split().0 }}"
That takes the second line (tomcat_status.stdout_lines.1) then splits it on whitespace (.split()), and then takes the first value (.0).
Here's a complete test:
- hosts: localhost
vars:
tomcat_status:
stdout_lines:
- "STATE STIME FMRI"
- "online 20:11:48 svc:/network/tomcat:tomcat"
tasks:
- set_fact:
tomcat_state: "{{ tomcat_status.stdout_lines.1.split().0 }}"
- debug:
var: tomcat_state
Running that playbook results in:

Team,
My task is running she’ll commands on hosts that are pulled from registered variable. Currently two hosts but there will be 100 in production.
am unable to read out stdout or stdout_lines. my task and output is below. Its sshing to the remove server and then runnning df -h command and storing output.

does not output anything..
I cannot reproduce your results - I believe that you left out some information when posting.
For example, do your tasks by any chance run on different hosts? The "raid_info" variable is registered per host, so if your tasks run on different hosts this might cause your issue.

Could anyone help me out with this?
There a few things wrong with this playbook:
don't set a space character between parameter and :
use service module instead of command module
This should work:
---
- hosts: openstack
connection: ssh
remote_user: ec2-user
become: True
gather_facts: False
tasks:
- name: Stop and disable firewalld.
service:
name: firewalld
state: stopped
enabled: False
if firewalld not installed/not running you can simply ignore error message using "failed_when:"
To avoid Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg
- name: 'Disable firewalld Services'
service:
name: "{{item}}"
state: stopped
enabled: no
loop:
- firewalld
register: firewalld_service_disable
failed_when: "firewalld_service_disable|failed and ('Could not find the requested service' not in firewalld_service_disable.msg)"
ignore_errors: yes
tags: test
Below is the anisble playbook execution output
# ansible-playbook main.yml --tags test

If your ansible version 2.9 and later , follow below "service_facts" method
- name: 'Populate service facts'
service_facts:

Below is my simple playbook
name: "test"
hosts: webservers
tasks:
- name: Echo my_env_var
shell: "echo $MY_ENV_VARIABLE"
environment:
MY_ENV_VARIABLE: whatever_value
- name: Echo my_env_var again
shell: "echo $MY_ENV_VARIABLE"

- debug: msg={{stdd.stdout_lines}}
My output is always msg:"" or msg: []. Why am i not able to see the value of variable
I took your example and changed it from debug msg to debug var. I also simplified it by only running the task once, and found the error in the process. The environment argument is specific to a task. You aren't including it in your second shell task.
Here's the example I used.
