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.
General Options:
` + generalOptionsUsage() + `
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
be 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.
