I am trying to run a loop over a task and I am registering the results. The items in the loop are not unique and can repeat. I don’t want to run the same item twice. So, in the same task, I want to use a conditional to check if the current loop item has run so far in the loop. For this, I use the registered variable and using some filters, I try to extract the items that were not skipped so far. (I know I could use the unique filter for the use case above. But this is a trimmed down version of the actual use case where each loop item is a list where the first item can be common among different loop items, apply: tags is used, etc).
In the example below, instead of skipped I use failed to keep the example simple.
- hosts:
- localhost
gather_facts: no
tasks: - debug: msg=item
loop: [1,2,3,1,2,3,4,5]
loop_control:
index_var: index
failed_when: index == 3
register: r
ignore_errors: true
when: - ‘item not in r.results | d() | reject(“failed”) | map(attribute=“item”) | flatten’
- debug:
msg: “{{ r.results | d() | reject(‘failed’) | map(attribute=‘item’) | flatten }}”
I know this example could be rewritten with until, I just constructed it to demonstrate my point.
The first tasks prints all loop items. The second one shows however that item number 3 was failed.
Is there a way to access the results from previous loop items somehow? Is this sth I should request on github from the ansible team?
