Usage: vault seal-status [options]

  Outputs the state of the Vault, sealed or unsealed.

  This command outputs whether or not the Vault is sealed. The exit
  code also reflects the seal status (0 unsealed, 1 sealed, 2+ error).

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.
