flattened – return single list completely flattened¶
Synopsis¶
- given one or more lists, this lookup will flatten any list elements found recursively until only 1 list is left.
Notes¶
Note
- unlike ‘items’ which only flattens 1 level, this plugin will continue to flatten until it cannot find lists anymore.
- aka highlander plugin, there can only be one (list).
Examples¶
- name: "'unnest' all elements into single list"
debug: msg="all in one list {{lookup('flattened', [1,2,3,[5,6]], [a,b,c], [[5,6,1,3], [34,a,b,c]])}}"

Hint
If you notice any issues in this documentation, you can edit this document to improve it.
Hint
Configuration entries for each entry type have a low to high priority order. For example, a variable that is lower in the list will override a variable that is higher up.
