Usage: vault kv put [options] KEY [DATA]
|
||
|
||
Writes the data to the given path in the key-value store. The data can be of
|
||
any type.
|
||
|
||
$ vault kv put secret/foo bar=baz
|
||
|
||
The data can also be consumed from a file on disk by prefixing with the "@"
|
||
symbol. For example:
|
||
|
||
$ vault kv put secret/foo @data.json
|
||
|
||
Or it can be read from stdin using the "-" symbol:
|
||
|
||
$ echo "abcd1234" | vault kv put secret/foo bar=-
|
||
|
||
To perform a Check-And-Set operation, specify the -cas flag with the
|
||
appropriate version number corresponding to the key you want to perform
|
||
the CAS operation on:
|
||
|
||
$ vault kv put -cas=1 secret/foo bar=baz
|
||
|
||
Additional flags and more advanced use cases are detailed below.
