**Product:** tt CLI **Since:** with Tarantool 3.0 **Audience/target:** all **Root document:** https://www.tarantool.io/en/doc/latest/reference/commands/ **SME:** @ psergee @ oleg-jukovec # Details _To do in scope of #3725_ The patch adds a new argument `key` that could be specified via etcd URI: * key - a target configuration key in the prefix. A user can now perform operations (`show` and `publish`) on individual keys in etcd, not just for entire prefixes. As example: ``` $ tt cluster show https://user:pass@localhost:2379/prefix?key=target ``` Requested by @oleg-jukovec in https://github.com/tarantool/tt/commit/7fe9f113f71cbe4153a2e340e4e620d664d5c3f2.
