- Add filter `dict_kv` which returns a single key-value pair dictionary created from two arguments Example 1 ``` - hosts: localhost gather_facts: false vars: myvar: myvalue tasks: - debug: msg: "{{ myvar | dict_kv('thatsmyvar') }}" OUTPUT: ok: [localhost] => { "msg": { "thatsmyvar": "myvalue" } } ``` Example 2 ``` - hosts: localhost gather_facts: false vars: common_config: type: host database: all myservers: - server1 - server2 tasks: - debug: msg: "{{ myservers | map('dict_kv', 'server') | map('combine', common_config) }}" OUTPUT: ok: [localhost] => { "msg": [ { "database": "all", "server": "server1", "type": "host" }, { "database": "all", "server": "server2", "type": "host" } ] } ```
