etcdctl

Interact with etcd, a highly-available key-value pair store. More information: https://etcd.io/docs/latest/dev-guide/interacting_v3/.

• Display the value associated with a specified key:
  etcdctl get {{my/key}}
• Store a key-value pair:
  etcdctl put {{my/key}} {{my_value}}
• Delete a key-value pair:
  etcdctl del {{my/key}}
• Store a key-value pair, reading the value from a file:
  etcdctl put {{my/file}} < {{path/to/file.txt}}
• Save a snapshot of the etcd keystore:
  etcdctl snapshot save {{path/to/snapshot.db}}
• Restore a snapshot of an etcd keystore (restart the etcd server afterwards):
  etcdctl snapshot restore {{path/to/snapshot.db}}
• Add a user:
  etcdctl user add {{my_user}}
• Watch a key for changes:
  etcdctl watch {{my/key}}
