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
