`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}}`
