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.
