Configuration options for the flagd provider

Fields

host: String

Host address for the service

port: u16

Port number for the service

target_uri: Option<String>

Target URI for custom name resolution (e.g. “envoy://service/flagd”)

resolver_type: ResolverType

Type of resolver to use

tls: bool

Whether to use TLS for connections (uses HTTPS/gRPCS) When enabled, connections will use TLS with system/webpki root certificates by default. For self-signed or custom CA certificates, also set cert_path.

cert_path: Option<String>

Path to a PEM-encoded CA certificate file for TLS connections. Use this to connect to flagd servers using self-signed or custom CA certificates. When provided, this certificate is used as the trusted CA instead of system roots. Can also be set via the FLAGD_SERVER_CERT_PATH environment variable. Example: “/path/to/ca-cert.pem”

deadline_ms: u32

Request timeout in milliseconds

cache_settings: Option<CacheSettings>

Cache configuration settings

retry_backoff_ms: u32

Initial backoff duration in milliseconds for retry attempts (default: 1000ms) Not supported in OFREP (REST) evaluation

retry_backoff_max_ms: u32

Maximum backoff duration in milliseconds for retry attempts, prevents exponential backoff from growing indefinitely (default: 120000ms) Not supported in OFREP (REST) evaluation

retry_grace_period: u32

Maximum number of retry attempts before giving up (default: 5) Not supported in OFREP (REST) evaluation

selector: Option<String>

Source selector for filtering flag configurations Used to scope flag sync requests in in-process evaluation

socket_path: Option<String>

Unix domain socket path for connecting to flagd When provided, this takes precedence over host:port configuration Example: “/var/run/flagd.sock” Only works with GRPC resolver

source_configuration: Option<String>

Source configuration for file-based resolver

stream_deadline_ms: u32

The deadline in milliseconds for event streaming operations. Set to 0 to disable. Recommended to prevent infrastructure from killing idle connections.

keep_alive_time_ms: u64

HTTP/2 keepalive time in milliseconds. Sends pings to keep connections alive during idle periods, allowing RPCs to start quickly without delay. Set to 0 to disable.

offline_poll_interval_ms: Option<u32>

Offline polling interval in milliseconds

provider_id: Option<String>

Provider ID for identifying this provider instance to flagd Used in in-process resolver for sync requests
