[ansible-devel] wait_for -> check for no moving logs, and skip string "Consul Health Check"

[Denny Fuchs]

hi,

at the moment we use something like:

  - name: wait for possible traffic
shell: "tail -n 5 /var/log/nginx/ssl-*access*log"
register: watch_nginx_log
retries: 30
delay: 5
until: "watch_nginx_log.stdout_lines | reject('search','nginx_status') 
| list | count == 0"
when: zero_weight is defined




The goal is to search, if there is _any_ string in the Nginx log file, but 
drop/skip the nginx_status, which comes from a Consul health check. So, if 
there is any other string, "wait_for" should "wait" and counting, until 
there is no other lines and then do the next part. An example logfile with 
no other strings looks like:


172.16.1.4 - - [29/Aug/2019:08:43:22 +0200] "GET /nginx_status HTTP/1.1" 
200 111 "-" "Consul Health Check"
172.16.1.4 - - [29/Aug/2019:08:43:42 +0200] "GET /nginx_status HTTP/1.1" 
200 111 "-" "Consul Health Check"
172.16.1.4 - - [29/Aug/2019:08:44:02 +0200] "GET /nginx_status HTTP/1.1" 
200 111 "-" "Consul Health Check"
172.16.1.4 - - [29/Aug/2019:08:44:22 +0200] "GET /nginx_status HTTP/1.1" 
200 111 "-" "Consul Health Check"
172.16.1.4 - - [29/Aug/2019:08:44:42 +0200] "GET /nginx_status HTTP/1.1" 
200 111 "-" "Consul Health Check"
172.16.1.4 - - [29/Aug/2019:08:45:02 +0200] "GET /nginx_status HTTP/1.1" 
200 111 "-" "Consul Health Check"



I want to replace it with a more Ansible way. I found, that there is a 
"wait_for" with search_regex. Is it possible ? I have to do the same with a 
squid access.log :-)

[ansible-devel] Execute module only, if package is installed

[Denny Fuchs]

hi,

I'm pretty new to Ansible (2.8 on Debian Stretch) and we have very simple 
playbook for upgrading packages, including run rkhunter / puppet / reboot 
etc. My problem is, that I do not have puppet an all nodes installed, so I 
tried:

---
#vim:ts=2:sts=2:sw=2:et
  - hosts: all
serial: 1
tasks:
  - name: Gather package facts
package_facts:
  manager: auto
  - name: Run puppet to apply last changes
puppet:

  - include_tasks: update_packages.yaml

  - include_tasks: reboot.yaml

  - name: "Puppet test result"
debug:
  msg: "Puppet found"
when: "'puppet' in ansible_facts.packages"

  - name: Run puppet to fix possible changes
puppet:

Problem is: on  nodes where "puppet" is installed, puppet is skipped and on 
nodes, where puppet is NOT install, the task fails. What I'm doing wrong ?
