task order execution

[Peter Hudec]

Hi,

I'm facin g following ISSUE.

My roles are mostly multi distribution enabled. My testing env is based
on 8 different distribution/releases
- debian 7/8, ubuntu 14.04/16.04, centos 6/7, rhel 6/7

My way how to do distribution specific task is as follow

air-2:zabbix-agent hudecof$ cat tasks/main.yml
---
# tasks file for zabbix-agent

- name: "common | set os specific variables"
include_vars: "{{ item }}"
with_first_found:
- "os-{{ ansible_distribution }}-{{ ansible_distribution_release }}.yml"
- "os-{{ ansible_distribution }}-{{ ansible_distribution_version }}.yml"
- "os-{{ ansible_distribution }}-{{
ansible_distribution_major_version }}.yml"
- "os-{{ ansible_distribution }}.yml"
- "os-default.yml"
tags:
- zabbix-agent

- name: "run os specific tasks"
include: "{{ task_item }}"
with_items: "{{ zabbix_agent_tasks }}"
loop_control:
loop_var: task_item
tags:
- zabbix-agent

air-2:zabbix-agent hudecof$ cat vars/os-Debian.yml
---
# list of packages to install
zabbix_agent_tasks:
- packages-Debian.yml
- common-config.yml
- common-service.yml
- common-facts.yml

zabbix_agent_packages:
- zabbix-agent

# name of the service
zabbix_agent_service: zabbix-agent

# user and group
zabbix_agent_user: zabbix
zabbix_agent_group: zabbix


air-2:zabbix-agent hudecof$ cat vars/os-CentOS.yml
---
# list of packages to install
zabbix_agent_tasks:
- packages-CentOS.yml
- common-config.yml
- common-service.yml
- common-facts.yml

zabbix_agent_packages:
- zabbix-agent

# name of the service
zabbix_agent_service: zabbix-agent

# user and group
zabbix_agent_user: zabbix
zabbix_agent_group: zabbix



When I run the role against full test set, the task execution order is like

That means, the ansible is executing the debian package install on
debian based distributions /common for debian and ubuntu/, then is
running tasks common for all distributions ..
And that the problem.. I need to run the CentOS/ReadHat install package
tasks before, see the errors

Workaround is to set serial to 1, but this not a option ;(

[Peter Hudec]

I created test role to demostrate the problem, could be on github
https://github.com/hudecof/sensible_test

The output log on 8 different OS
- debian:7,8
- centos: 6,7
- ubuntu: 14.04, 16.04
- rhel: 6,7

is in logs directory
https://github.com/hudecof/sensible_test/blob/master/logs/full_run.log

As you can see, the task 01 for debian/ubuntu is run first, then is run
task 02, which is common for all servers and after that is run task 01
from centos/rhel.

On vars/os-XXXX.yml is the task order defined and I need to run the task
in that order, They are defendant ;(
Any advise?

Peter
