@mitchellh suggested we fork `cli` and switch to that. Since we primarily use the interfaces in `cli`, and the new fork has not changed those, this is (mostly) a drop-in replacement. A small fix will be necessary for Vault Enterprise, I believe.

Usage: vault patch [options] PATH [DATA K=V...]
|
|
|
|
Patches data in Vault at the given path. The data can be credentials, secrets,
|
|
configuration, or arbitrary data. The specific behavior of this command is
|
|
determined at the thing mounted at the path.
|
|
|
|
Data is specified as "key=value" pairs. If the value begins with an "@", then
|
|
it is loaded from a file. If the value is "-", Vault will read the value from
|
|
stdin.
|
|
|
|
Unlike write, patch will only modify specified fields.
|
|
|
|
Persist data in the generic secrets engine without modifying any other fields:
|
|
|
|
$ vault patch pki/roles/example allow_localhost=false
|
|
|
|
The data can also be consumed from a file on disk by prefixing with the "@"
|
|
symbol. For example:
|
|
|
|
$ vault patch pki/roles/example @role.json
|
|
|
|
Or it can be read from stdin using the "-" symbol:
|
|
|
|
$ echo "example.com" | vault patch pki/roles/example allowed_domains=-
|
|
|
|
For a full list of examples and paths, please see the documentation that
|
|
corresponds to the secret engines in use.
