Usage: vault init [options]

|
Initialize a new Vault server.
|
|
|
|
This command connects to a Vault server and initializes it for the
|
|
first time. This sets up the initial set of master keys and sets up the
|
|
backend data store structure.
|
|
|
|
This command can't be called on an already-initialized Vault.

|
Init Options:
|
|
|
|
-check Don't actually initialize, just check if Vault is
|
|
already initialized. A return code of 0 means Vault
|
|
is initialized; a return code of 2 means Vault is not
|
|
initialized; a return code of 1 means an error was
|
|
encountered.
|
|
|
|
-key-shares=5 The number of key shares to split the master key
|
|
into.
|
|
|
|
-key-threshold=3 The number of key shares required to reconstruct
|
|
the master key.
|
|
|
|
-pgp-keys If provided, must be a comma-separated list of
|
|
files on disk containing binary- or base64-format
|
|
public PGP keys, or Keybase usernames specified as
|
|
"keybase:<username>". The number of given entries
|
|
must match 'key-shares'. The output unseal keys will
|
|
encrypted and hex-encoded, in order, with the given
|
|
public keys. If you want to use them with the 'vault
|
|
unseal' command, you will need to hex decode and
|
|
decrypt; this will be the plaintext unseal key.
