Disable write permission for etcd key?

Question

I use etcdctl put /my/branch/1 value123 to insert value into /my/branch/1. I want to remove write access for that /my/branch/1 key using etcdctl, how can I do that?

Seems that role grant-permission or revoke-permission doesn't work, so I can still add values into that key.

See my answer on your latest question about etcd and permissions. You have to have two type of clients: a) master TLS cert b) other TLS certs

To master you grant-role root master and therefore you have master client that can control etcd, whereas all other clients would have restricted access as you wish
