Definition

SPIRE (the SPIFFE Runtime Environment) is an open-source system that implements the SPIFFE (Secure Production Identity Framework for Everyone) specification. It provides a robust framework for securely issuing, rotating, and revoking identities across heterogeneous environments. SPIRE is designed to manage service identities in dynamic and distributed systems, ensuring that workloads can securely authenticate and communicate with each other.

Secure Settings Example

server {
  bind_address = "0.0.0.0"
  bind_port = "8081"
  trust_domain = "example.org"
  data_dir = "/opt/spire/data"
  ca_key_type = "rsa-2048"
  ca_subject = {
    country = "US"
    organization = "ExampleOrg"
    common_name = "SPIRE CA"
  }
  federation {
    bundle_endpoint {
      address = "0.0.0.0"
      port = "8443"
      acls = ["192.168.1.0/24"]
    }
  }
}

Insecure Settings Example

server {
  bind_address = "0.0.0.0"
  bind_port = "8081"
  trust_domain = "example.org"
  data_dir = "/opt/spire/data"
  ca_key_type = "rsa-2048"
  ca_subject = {
    country = "US"
    organization = "ExampleOrg"
    common_name = "SPIRE CA"
  }
  federation {
    bundle_endpoint {
      address = "0.0.0.0"
      port = "8443"
      acls = ["0.0.0.0/0"]  # Insecure: Allows access from any IP address
    }
  }
}
