Hey folks,
I have run into a problem that I have not been able to solve -- I hope
somebody out there has had better luck than I have. Here's the setup:
At the top level directory there is an executive shell script that calls a
playbook, the particular playbook called is based on inputs to the script.
For each playbook there is a corresponding role subdirectory, and each role
subdirectory is further divided into a tasks subdirectory and a vars
subdirectory. There is one vars file corresponding to each task file. Each
role contains a set of unique tasks. If a task is used in more than one
playbook then the tasks and vars files are located under the common
subdirectory.
The structure of my current ansible hierarchy is shown below. Note that the
common subdirectory and the compA and compB subdirectories look similar to
the compN subdirectory, but only the compN subdirectory is shown in detail
for simplification.
top-level directory:
compA_playbook.yaml
compB_playbook.yaml
…
compN_playbook.yaml
executive.sh
roles
|- common
|- compA
|- compB
…
|- compN
|- tasks
| task1.yaml
| task2.yaml
| …
| taskm.yaml
|- vars
task1.yaml
task2.yaml
…
taskm.yaml
A typical playbook looks like this:
---
- hosts: localhost
vars_files:
- roles/common/vars/fxn_1.yaml
tasks:
- name: function 1
import_tasks: roles/common/tasks/fxn_1.yaml
…
A typical vars file looked like this:
---
fxn_1_bool: true
fxn_1_id: ddtnn35
fxn_1_cfgfile: '"/xyz/home/user2/.functionX.cfg"'
fxn_1_starttime: "2020-09-30 07:30:00"
fxn_1_pauseinterval: 1
and a typical task file looked like this:
---
- name: set downtime
shell: >
/opt/bin/set_downtime.py {{ item }} downtime add
-t {{fxn_1_starttime}} -u {{fxn_1_id}};
loop: "{{ query('inventory_hostnames', '{{ HPC }}-spares') }}"
loop_control:
pause: "{{ fxn_1_pauseinterval }}"
when: fxn_1_bool
register: set_fxn_1
tags: [ FXN_1 ]
The code is written so that the user may specify that an entire playbook be
executed (by default) OR that one or more tasks within a playbook could be
executed by specifying the appropriate tags (each task has a unique tag).
This setup worked fine until I needed to add conditionals to choose between
var files for certain tasks. I could only get the conditionals to work by
replacing “vars_files:” with “include_vars:”; so now a typical playbook
looks like this:
---
- hosts: localhost
tasks:
- include_vars: roles/common/vars/fxn_1.yaml
when: newVar1 == true or newVar2 == true
- include_vars: /some/other/dir/fxn_1.yaml
when: newVar1 == false and newVar2 == false
- name: function 1
import_tasks: roles/common/tasks/fxn_1.yaml
The conditional clauses work fine – the correct var file is chosen based on
the values on newVar1 and newVar2. The problem comes when I use tags.
When I specify a tag the tag is only associated with the task, but NOT
associated with the include_vars, so when the task executes it fails
because the variables are undefined.
I need some way to attach the tag to the variable files as well as the
tasks files. I have tried using ansible block, but couldn’t get that to
work. Any input appreciated!
