Environment variables

These environment variables affect the behavior of the pilot-discovery command.

Variable NameTypeDefault ValueDescription
AUDIENCEStringExpected audience in the tokens.
AUTHZ_FAILURE_LOG_BURST_SIZEInteger1
AUTHZ_FAILURE_LOG_FREQTime Duration1m0s
BYPASS_OOP_MTLS_SAN_VERIFICATIONBooleanfalseWhether or not to validate SANs for out-of-process adapters auth.
CITADEL_ENABLE_JITTER_FOR_ROOT_CERT_ROTATORBooleantrueIf true, set up a jitter to start root cert rotator. Jitter selects a backoff time in seconds to start root cert rotator, and the back off time is below root cert check interval.
CITADEL_SELF_SIGNED_CA_CERT_TTLTime Duration87600h0m0sThe TTL of self-signed CA root certificate.
CITADEL_SELF_SIGNED_ROOT_CERT_CHECK_INTERVALTime Duration1h0m0sThe interval that self-signed CA checks its root certificate expiration time and rotates root certificate. Setting this interval to zero or a negative value disables automated root cert check and rotation. This interval is suggested to be larger than 10 minutes.
CITADEL_SELF_SIGNED_ROOT_CERT_GRACE_PERIOD_PERCENTILEInteger20Grace period percentile for self-signed root cert.
ISTIOD_ADDRStringService name of istiod. If empty the istiod listener, certs will be disabled.
ISTIO_GPRC_MAXSTREAMSInteger100000Sets the maximum number of concurrent grpc streams.
ISTIO_LANGStringSelects the attribute expression language runtime for Mixer.
K8S_INGRESS_NSString
KUBERNETES_SERVICE_HOSTStringKuberenetes service host, set automatically when running in-cluster
MAX_WORKLOAD_CERT_TTLTime Duration2160h0m0sThe max TTL of issued workload certificates.
PILOT_BLOCK_HTTP_ON_443BooleantrueIf enabled, any HTTP services will be blocked on HTTPS port (443). If this is disabled, any HTTP service on port 443 could block all external traffic
PILOT_CERT_DIRString
PILOT_DEBOUNCE_AFTERTime Duration100msThe delay added to config/registry events for debouncing. This will delay the push by at least this internal. If no change is detected within this period, the push will happen, otherwise we'll keep delaying until things settle, up to a max of PILOT_DEBOUNCE_MAX.
PILOT_DEBOUNCE_MAXTime Duration10sThe maximum amount of time to wait for events while debouncing. If events keep showing up with no breaks for this time, we'll trigger a push.
PILOT_DEBUG_ADSZ_CONFIGBooleanfalse
PILOT_DISABLE_XDS_MARSHALING_TO_ANYBooleanfalse
PILOT_DISTRIBUTION_HISTORY_RETENTIONTime Duration1m0sIf enabled, Pilot will keep track of old versions of distributed config for this duration.
PILOT_ENABLE_CONFIG_DISTRIBUTION_TRACKINGBooleantrueIf enabled, Pilot will assign meaningful nonces to each Envoy configuration message, and allow users to interrogate which envoy has which config from the debug interface.
PILOT_ENABLE_CRD_VALIDATIONBooleanfalseIf enabled, pilot will validate CRDs while retrieving CRDs from kubernetes cache.Use this flag to enable validation of CRDs in Pilot, especially in deployments that do not have galley installed.
PILOT_ENABLE_EDS_DEBOUNCEBooleantrueIf enabled, Pilot will include EDS pushes in the push debouncing, configured by PILOT_DEBOUNCE_AFTER and PILOT_DEBOUNCE_MAX. EDS pushes may be delayed, but there will be fewer pushes. By default this is enabled
PILOT_ENABLE_FALLTHROUGH_ROUTEBooleantrueEnableFallthroughRoute provides an option to add a final wildcard match for routes. When ALLOW_ANY traffic policy is used, a Passthrough cluster is used. When REGISTRY_ONLY traffic policy is used, a 502 error is returned.
PILOT_ENABLE_HEADLESS_SERVICE_POD_LISTENERSBooleantrueIf enabled, for a headless service/stateful set in Kubernetes, pilot will generate an outbound listener for each pod in a headless service. This feature should be disabled if headless services have a large number of pods.
PILOT_ENABLE_MYSQL_FILTERBooleanfalseEnableMysqlFilter enables injection of envoy.filters.network.mysql_proxy in the filter chain.
PILOT_ENABLE_PROTOCOL_SNIFFING_FOR_INBOUNDBooleantrueIf enabled, protocol sniffing will be used for inbound listeners whose port protocol is not specified or unsupported
PILOT_ENABLE_PROTOCOL_SNIFFING_FOR_OUTBOUNDBooleantrueIf enabled, protocol sniffing will be used for outbound listeners whose port protocol is not specified or unsupported
PILOT_ENABLE_REDIS_FILTERBooleanfalseEnableRedisFilter enables injection of envoy.filters.network.redis_proxy in the filter chain.
PILOT_ENABLE_UNSAFE_REGEXBooleanfalseIf enabled, pilot will generate Envoy configuration that does not use safe_regex but the older, deprecated regex field. This should only be enabled to support legacy deployments that have not yet been migrated to the new safe regular expressions.
PILOT_HTTP10BooleanfalseEnables the use of HTTP 1.0 in the outbound HTTP listeners, to support legacy applications.
PILOT_INBOUND_PROTOCOL_DETECTION_TIMEOUTTime Duration1sProtocol detection timeout for inbound listener
PILOT_INITIAL_FETCH_TIMEOUTTime Duration0sSpecifies the initial_fetch_timeout for config. If this time is reached without a response to the config requested by Envoy, the Envoy will move on with the init phase. This prevents envoy from getting stuck waiting on config during startup.
PILOT_PUSH_THROTTLEInteger100Limits the number of concurrent pushes allowed. On larger machines this can be increased for faster pushes
PILOT_RESPECT_DNS_TTLBooleantrueIf enabled, DNS based clusters will respect the TTL of the DNS, rather than polling at a fixed rate. This option is only provided for backward compatibility purposes and will be removed in the near future.
PILOT_RESTRICT_POD_UP_TRAFFIC_LOOPBooleantrueIf enabled, this will block inbound traffic from matching outbound listeners, which could result in an infinite loop of traffic. This option is only provided for backward compatibility purposes and will be removed in the near future.
PILOT_SCOPE_GATEWAY_TO_NAMESPACEBooleanfalseIf enabled, a gateway workload can only select gateway resources in the same namespace. Gateways with same selectors in different namespaces will not be applicable.
PILOT_SCOPE_PUSHESBooleantrueIf enabled, pilot will attempt to limit unnecessary pushes by determining what proxies a config or endpoint update will impact.
PILOT_SIDECAR_USE_REMOTE_ADDRESSBooleanfalseUseRemoteAddress sets useRemoteAddress to true for side car outbound listeners.
PILOT_SKIP_VALIDATE_TRUST_DOMAINBooleanfalseSkip validating the peer is from the same trust domain when mTLS is enabled in authentication policy
PILOT_TRACE_SAMPLINGFloating-Point100Sets the mesh-wide trace sampling percentage. Should be 0.0 - 100.0. Precision to 0.01. Default is 100, not recommended for production use.
POD_NAMEString
POD_NAMESPACEString
ROOT_CA_DIRString./etc/cacertsLocation of a local or mounted CA root
TERMINATION_DRAIN_DURATION_SECONDSInteger5The amount of time allowed for connections to complete on pilot-agent shutdown. On receiving SIGTERM or SIGINT, pilot-agent tells the active Envoy to start draining, preventing any new connections and allowing existing connections to complete. It then sleeps for the TerminationDrainDuration and then kills any remaining active Envoy processes.
TOKEN_ISSUERStringOIDC token issuer. If set, will be used to check the tokens.
USE_ISTIO_JWT_FILTERBooleanfalseUse the Istio JWT filter for JWT token verification.
WEBHOOKStringName of webhook config to patch, if istioctl is not used.
WORKLOAD_CERT_TTLTime Duration2160h0m0sThe TTL of issued workload certificates.
