# 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}}`
