Usage: vault write [options] path [data]
|
|
|
|
Write data (secrets or configuration) into Vault.
|
|
|
|
Write sends data into Vault at the given path. The behavior of the write
|
|
is determined by the backend at the given path. For example, writing
|
|
to "aws/policy/ops" will create an "ops" IAM policy for the AWS backend
|
|
(configuration), but writing to "consul/foo" will write a value directly
|
|
into Consul at that key. Check the documentation of the logical backend
|
|
you're using for more information on key structure.
|
|
|
|
Data is sent via additional arguments in "key=value" pairs. If value
|
|
begins with an "@", then it is loaded from a file. Write expects data in the
|
|
file to be in JSON format. If you want to start the value with a literal "@",
|
|
then prefix the "@" with a slash: "\@".
|
|
|
|
General Options:
|
|
|
|
` + generalOptionsUsage() + `
|
|
|
|
Write Options:
|
|
|
|
-f | -force Force the write to continue without any data values
|
|
specified. This allows writing to keys that do not
|
|
need or expect any fields to be specified.
