Vault is not configured to use TLS, please provide a set of certificates. It is strongly discouraged to use Vault without TLS.
Vault is not initialized as the key shards need to be distributed to key holders, and it is suggested to encrypt them with GPG. Please refer to the Vault documentation.
Nomad is not configured to use Vault as it requires a Vault Token. Please refer to the Nomad documentation for information on how to configure the integration.
