etcdctl

CLI interface for interacting with etcd, a highly-available key-value pair store.

• 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}
