I'm new in Ansible and I try to do some practice playbook. I write a playbook to deploy a Docker container as follows. I write a task in the block section if an error happened, run a task in the rescue section based on Failed message content. For example, I want to run a specific task to delete an existing container if the Failed message is something like this:
failed: [192.168.1.140] (item=stderr_lines) => {"changed": true, "cmd": ["docker", "run", "-itd", "--name", "h1", "-p", "80:80", "httpd"], "delta": "0:00:00.016385", "end": "2021-01-04 03:00:55.403364", "failed_when_result": true, "item": "stderr_lines", "msg": "non-zero return code", "rc": 125, "start": "2021-01-04 03:00:55.386979", "stderr": "/usr/bin/docker-current: Error response from daemon: Conflict.

My playbook is as follows but it didn't work correctly. Sometimes an error in reading dictionary or "Unexpected templating type error occurred on". Can somebody guide me on what should I write?

Team,
I am writing a validation task that is supposed to just check if a mount exists or not and report its state from output. so my task is below but it fails and am not sure how to handle it. any hint what adjustments do i need to make?

shell: "mount | grep sdd"
register: lvp_mount
delegate_to: "{{ item }}"
with_items: "{{ groups['kube-cpu-node'] }}"
#failed_when: lvp_mount.rc != 0
#ignore_errors: yes
# - debug:
# var: lvp_mount
- name: "Report status of mounts"
fail:

[WARNING]: Consider using the mount module rather than running 'mount'. If you
need to use command because mount is insufficient you can add 'warn: false' to
this command task or set 'command_warnings=False' in ansible.cfg to get rid of
this message.

Your task "Verify LVP Mounts on CPU Nodes for mount_device" is a loop so the register behavior is modified as specified in the documentation.
You can access the various outputs with lvp_mount.results.X.stdout where X is the index.
There is a cleaner way to write your script however. More specifically using:
delegate_to: "{{ item }}"
with_items: "{{ groups['kube-cpu-node'] }}"
is bad practice. You can accomplish your desired outcome at the play level.
For example:
- hosts: kube-cpu-node # allows you to iterate over all hosts in kube-cpu-node group
tasks:
- name: "Verify LVP Mounts on CPU Nodes for mount_device"
shell: "mount | grep sdd"
register: lvp_mount
ignore_errors: yes
# notice there is no loop here
- name: "Report status of mounts"
fail:
msg: |
Mounts sdd not found
Output of `mount | grep sdd`:
{{ lvp_mount.stdout }} # no loop so you can use lvp_mount.stdout
{{ lvp_mount.stderr }} # no loop so you can use lvp_mount.stderr

I am trying to one simple task which is find out the difference between the two files and store it in notepad. I am not able to do it with command as well as shell. Please suggest where i am going wrong-
---
- hosts: myserver
tasks:
- name: get the difference
command: diff hosts.new hosts.mod
register: diff
- debug: var=diff.cmd
Error -
fatal: [zlp12037]: FAILED! => {"changed": true, "cmd": ["diff", "hosts.new", "hosts.mod"], "delta": "0:00:00.003102", "end": "2017-03-29 10:17:34.448063", "failed": true, "rc": 1, "start": "2017-03-29 10:17:34.444961", "stderr": "", "stdout":
I'm not quite sure what your input play looks like with your formatting. But the following should be a solution:
- name: "Get difference from two files"
command: diff filea fileb
args:
chdir: "/home/user/"
failed_when: "diff.rc > 1"
register: diff
- name: debug output
debug: msg="{{ diff.stdout }}"
Some explanation:
If something fails with the diff command, the return code is > 1. We evaluate this by the "failed_when".
To get the output of the command, we print the ".stdout" element.
To make sure we're in the folder where the files are, we use "chdir".
I would move the hosts.new or hosts.mod to the ansible control machine.
Run the copy module with the src as hosts.new and the dest as hosts.mod with --check and --diff. I find this method most useful to spot differences in files across a large enterprise.
Run:
ansible all -m copy -a "src=hosts.new dest=/tmp/hosts.mod" --check --diff -i hosts
Output:
--- before: /tmp/hosts.mod
+++ after: /home/ansible/hosts.new
## -1,5 +1,5 ##

I am writing an ansible playbook that will :
log into a windows box
check if the version of the application i am deploying exists already
downloads the application from git
extracts the app's zip file
moves it to the correct directory
I am having a bunch of trouble on a section of the code where i need to find the extracted directory. I am extracting a GIT zip, and of course, through Github the zip file contains the git hash directory. What I do is i look for this directory through a simple find-like command in windows. The problem is that during debug, i can see the results in stdout_lines ... but in practice, it doesn't seem to work.
Here is the code:

Are you sure this works without an error? Because mesg is not a valid option in debug. Did you mean msg?
- debug: mesg={{ item }}
Anyway, the problem is you are using a wrong parameter. Use var instead since you are printing the value of a variable.
- debug: var={{ item }}
