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.
If data is "-" then the data will be ready from stdin. To write a literal
"-", you'll have to pipe that value in from stdin. To write data from a
file, pipe the file contents in via stdin and set data to "-".
If data is a string, it will be sent with the key of "value".
General Options:
-address=TODO The address of the Vault server.
-ca-cert=path Path to a PEM encoded CA cert file to use to
verify the Vault server SSL certificate.
-ca-path=path Path to a directory of PEM encoded CA cert files
to verify the Vault server SSL certificate. If both
-ca-cert and -ca-path are specified, -ca-path is used.
-insecure Do not verify TLS certificate. This is highly
not recommended. This is especially not recommended
for unsealing a vault.
