  • 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}}
