Hi all,

I am using ansible 2.4.2 as below:

[Leon Xie]

Hi all,

I found a bug on ansible 1.9.2 and have finished coding.
If I want this bug to be fixed in later 1.9.x release, which branch should 
I submit my pull request?
Should I submit to stable-1.9 branch or devel branch?

Best,
Leon

Re: [ansible-project] Re: ansible didn't stop execution upon a task failure

[Leon Xie]

Hi Brian,

Is there any way to abort 42 and 43 host if any task fails on 41 host?
As I know, "any_errors_fatal: True" and " max_fail_percentage: 0' can be 
used to archive this, however, it didn't work.

thank

[ansible-project] ansible didn't stop execution upon a task failure

[Leon Xie]

hi

I have the below ansible playbook named backup_data.yml, which is included 
by the main playbook named upgrade.yml.

backup_data.yml
++
---
- name: backup data
  hosts: allvm 
  remote_user: root
  max_fail_percentage: 0
  any_errors_fatal: True

prepare_vms.yml

[ansible-project] a question about 'Interrupt execution on any error'

[Leon Xie]

hi all,

according to the section entitled 'Interrupt execution on any error 
' in the 
below URL:
http://docs.ansible.com/ansible/playbooks_delegation.html#rolling-update-batch-size

I wrote the below playbook:


---
- hosts: host
  remote_user: root
  any_errors_fatal: True
  tasks:
- command: 'false'

- hosts: "allvm"
  any_errors_fatal: True
  remote_user: root
  tasks:
- command: 'true'


what I expect is that when tasks for 'host' fails, the task for 'allvm' 
won't be run.

however, I got the below output

[localhost]$ ansible-playbook -c paramiko -i hosts  demo.yml 

PLAY [host]

[ansible-project] how to abort task execution for other hosts if one task fails for one host

[Leon Xie]

hi all,

I have the below ansible playbook

++
- name: do task for AA
  hosts: AA
  roles:
- AA_ROLE

- name: do task for BB
  hosts: BB
  roles:
- BB_ROLE
++

Currently even if one task in AA_ROLE for AA fails, the tasks in BB_ROLE 
for BB will also be run.

what I want is that if any task in AA_ROLE fails, the tasks in BB_ROLE 
won't be executed.

is there any method to achieve this?

thanks a lot in advance.

Re: [ansible-project] how to abort execution upon a single fail on any host

[Leon Xie]

Hi Serge,

your suggestion about any_errors_fatal works for the hosts that in a single 
play.
if there is another play and one of the hosts in the play is not in the 
hosts that marked as any_errors_fatal, the tasks in this play will also be 
executed.

- backup_data

- hosts: localhost
  max_fail_percentage: 0
  roles:
- prepare_data

+++
what I get now is that even if any task in stop_server role fail, the task 
in backup_data for allhosts still runs.

what I want is that if any failure occurs in any host, the other tasks 
won't be run for the remaining hosts.
is there a way to achieve this?

[ansible-project] ansible known_hosts module failed

[Leon Xie]

Hi all,

I use the below playbook to add known hosts:


- name: demo
  hosts: 10.223.0.51
  remote_user: root
  tasks:
- name: fetch
  fetch: src=/etc/ssh/ssh_host_rsa_key.pub dest=/tmp/keys
 fail_on_missing=yes validate_checksum=yes
- name: demo
  hosts: 10.223.0.52
  remote_user: root
  tasks:
- name: known_hosts
  known_hosts: path="/home/xiaoliang/.ssh/known_hosts" host="sun1-db-1" 
state=present
   key="{{ lookup('file', 
'/tmp/keys/10.223.0.51/etc/ssh/ssh_host_rsa_key.pub') }}"




$ ansible-playbook  -i ../../inventory/hosts demo.yml -
