ansible when comparing integer values










0















This role attempts to get cpu temperatures from raspberry pi computers (host1 only in this case), check whether docker container boinc_universeathome is running, and then if the container is running and the cpu temp > highThresholdTrigger then it should pause the container.



If i run this without the when clauses in the role, then correctly it always pauses the container.



Why does it not work when the when clauses are present ever? i expect that with the when clauses present, it should only pause the container when the condition is met. But the condition is never met.



Presumably this is because there is something wrong with the way i am writing the when clauses but i dont know what it wrong?



(I know i'm using shell here and not a docker module)



My hosts:



[monitorrpihosts]
host1

[monitorrpihosts:vars]
ansible_connection=ssh
ansible_ssh_user=someusername
highThresholdTrigger=70
highThresholdReset=40


My playbook:



---
- name: Monitor rpi
hosts: monitorrpihosts
become: yes
become_user: root
become_method: sudo

roles:
- monitorrpi


My role:



---
- name: Get current cpu temp
shell: '/opt/vc/bin/vcgencmd measure_temp | grep ^temp= | cut -d= -f2 | cut -d. -f1'
register: cpu_temp

- name: check if boinc is running
shell: 'docker ps | grep boinc_universeathome | grep -v Paused'
ignore_errors: True
register: boinc_running

- name: pause boinc if cpu temp gt highThreshold
shell: 'docker pause boinc_universeathome'
when:
- cpu_temp.stdout_lines|int > highThresholdTrigger|int
- boinc_running.rc|int == 0
