ansiible: register when grep etc

PoleStar · 03-26-2018, 11:20 AM

Code:

- name: Httpd running ?
  shell: ps axo args |  grep httpd | grep -v grep 
  register: apache
  failed_when: false
  ignore_errors: yes <---- if this removed I get red error on non httpd servers

- name: Copy script
  get_url:
    url: "http://anotherscript.sh
    dest: /tmp/anotherscript.sh
    mode: 0755
    owner: root
    group: root
    force: yes
  when: apache.rc == 0

What I want is

Code:

when apache.rc == 0
   do  url; dest; mode; owner etc
   done
when apache.rc != 0 
    next

If I put " ignore_errors: yes " then it ignore apache.rc and do every thing(url, dest, mod etc) on a given server regardless it has httpd running or not.
If I remove " ignore_errors: yes " then it starts bringing red font errors on all the servers where httpd is not running.

Please help.

You have to implement a branch of some sort following the ps command, do you know how to do it in ansiible?

Btw, a way to avoid grep -v grep

Code:

ps axo args | grep [h]ttpd

ignore_errors may ignores the exit return status from ps | grep command, I don't know
