Re: [ansible-project] item variable not defined loop does not work well with stdout_lines

[Todd Lewis]

The inconsistencies in your indentation lead me to suspect you are 
withholding evidence. :) Assuming your code is this:


*- name: check previous kafka broker server.properties shell: "ps -ef | 
grep -i kafka | grep -i server.properties | awk '{print $NF}'" register: 
serverfile tags: - upgrade - upgrade12 - name: debug grepout set_fact: 
srvfilepath: "{{ item }}" loop: "{{ serverfile.stdout_lines }}" when: 
"'server' in item" tags: - upgrade - upgrade12 - name: get the 
interbroker and messge format version details if set shell: 'grep -e 
inter.broker.protocol.version -e log.message.format.version 
{{srvfilepath}}' register: regintbrkpt tags: - upgrade12 - name: display 
interbroker version debug: msg: "{{ item }}" loop: - 
"{{regintbrkpt.stdout_lines}}" tags: - upgrade12*


Because the "*display interbroker version*" task is claiming *item* is 
undefined, then the previous task is not registering anything containing 
*stdout_lines*. I would not be surprised to find the poorly named 
"*debug grepout*" task is not finding '*server*' in the expected output 
from the first task, possibly because the shell pipeline isn't producing 
what you expect.


Suggestions:
* Run with *-vv* until this is working reliably.
* Insert debug tasks after every task that registers to ensure the data 
you are passing to subsequent tasks is what you expect.
* Consider using *pgrep -f -a kafka* and *grep -o* with to extract 
relevant data from existing processes command lines.


Good luck; let us know what you find.

Use the module *wait_for*. See
https://docs.ansible.com/ansible/latest/collections/ansible/builtin/wait_for_module.html


If you run the play on *postgres1* the task is simple

  - hosts: postgres1
tasks:
  - wait_for:
  host: 
  port: 5432

If you run the play on multiple hosts you might want to run
once and delegate the task 

  - hosts: all
tasks:
  - wait_for:
  host: 
  port: 5432
delegate_to: postgres1
run_once: true

See: pg_isready
https://www.postgresql.org/docs/current/app-pg-isready.html

Re: [ansible-project] check connectivity (telnet

[Dick Visser]

Do you want to check if the server has an established connection to an IP
address?
Or if it is listening on a specific port?
There are perhaps better ways of finding out if a server is running at some
socket

[ansible-project] check connectivity (telnet

[dulhaver via Ansible Project]

hi,
 
I am running a playbook og a couple of postgres-remotes who play different 
roles in a complex server landscape.
 
Now I want to check to check whether i.e. postgres1 has a connection via port 
5432 to a specific IP address. The true/false like result of such a check 
should be saved into a variable.
 
Manually I could i.e. do this with something like 'telnet  5432'
 
what would be the right approach (aka module) for such in an Ansible TASK?
