Hello,
I try to figure out, how I can find the failed hosts in rescue.
My idea was to use:
- name: add failed hosts to the exclude list
add_host:
name: "{{ item }}"
groups: failed_hosts_in_block
when: hostvars:[item]['ansible_failed_result']['failed'] == true
with_items: "{{ stored_ansible_hosts }}"
stored_ansible_hosts contains all ansible_play_hosts right at the beginning
of the play.
The above code does not work, because when does not like the hostvar
variable somehow :) "conditional check errors". I tried a lot of possible
combinations
hostvars:[item]ansible_failed_result'.failed
hostvars:[item]['ansible_failed_result'].failed
hostvars:[item]['ansible_failed_result']['failed']
.
.
even:
- debug:
var: hostvars[hostname].ansible_failed_result.failed
or
- debug:
msg: "{{ hostvars[hostname].ansible_failed_result.failed }}"
gives the result "true"
For me, it is only important to find out, which host failed. There are a
lot of tasks in the block statement and it makes no sense to write error
handling for each single task, register the return code and take action on
this one. Also adding these hostnames to a list failed (thought that failed
hosts could not be added to a host group....)
I hope you can help!
Regards
