PILOT_ALLOW_METADATA_CERTS_DR_MUTUAL_TLS | Boolean | false | If true, Pilot will allow certs specified in Metadata to override DR certs in MUTUAL TLS mode. This is only enabled for migration and will be removed soon. |
PILOT_CERT_PROVIDER | String | istiod | The provider of Pilot DNS certificate. |
PILOT_DEBOUNCE_AFTER | Time Duration | 100ms | The delay added to config/registry events for debouncing. This will delay the push by at least this internal.

PILOT_ENABLE_EDS_FOR_HEADLESS_SERVICES | Boolean | false | If enabled, for headless service in Kubernetes, pilot will send endpoints over EDS, allowing the sidecar to load balance among pods in the headless service. This feature should be enabled if applications access all services explicitly via a HTTP proxy port in the sidecar. |
PILOT_ENABLE_FLOW_CONTROL | Boolean | false | If enabled, pilot will wait for the completion of a receive operation beforeexecuting a push operation. This is a form of flow control and is useful inenvironments with high rates of push requests to each gateway. By default,this is false. |
PILOT_ENABLE_HEADLESS_SERVICE_POD_LISTENERS | Boolean | true | If 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_INBOUND_PASSTHROUGH | Boolean | true | If enabled, inbound clusters will be configured as ORIGINAL_DST clusters. When disabled, requests are always sent to localhost. The primary implication of this is that when enabled, binding to POD_IP will work while localhost will not; when disable, bind to POD_IP will not work, while localhost will. The enabled behavior matches the behavior without Istio enabled at all; this flag exists only for backwards compatibility. Regardless of this setting, the configuration can be overridden with the Sidecar.Ingress.DefaultEndpoint configuration. |
PILOT_ENABLE_ISTIO_TAGS | Boolean | true | Determines whether or not trace spans generated by Envoy will include Istio-specific tags. |
PILOT_ENABLE_K8S_SELECT_WORKLOAD_ENTRIES | Boolean | true | If enabled, Kubernetes services with selectors will select workload entries with matching labels. It is safe to disable it if you are quite sure you don’t need this feature |
PILOT_ENABLE_LEGACY_AUTO_PASSTHROUGH | Boolean | false | If enabled, pilot will allow any upstream cluster to be used with AUTO_PASSTHROUGH. This option is intended for backwards compatibility only and is not secure with untrusted downstreams; it will be removed in the future. |
PILOT_ENABLE_MCS_SERVICEEXPORT | Boolean | false | If enabled, Pilot will generate MCS ServiceExport objects for every non cluster-local service in the cluster |
PILOT_ENABLE_MYSQL_FILTER | Boolean | false | EnableMysqlFilter enables injection of envoy.filters.network.mysql_proxy in the filter chain. |

PILOT_ENABLE_PROTOCOL_SNIFFING_FOR_OUTBOUND | Boolean | true | If enabled, protocol sniffing will be used for outbound listeners whose port protocol is not specified or unsupported |
PILOT_ENABLE_REDIS_FILTER | Boolean | false | EnableRedisFilter enables injection of envoy.filters.network.redis_proxy in the filter chain. |

PILOT_JWT_PUB_KEY_REFRESH_INTERVAL | Time Duration | 20m0s | The interval for istiod to fetch the jwks_uri for the jwks public key. |
PILOT_PUSH_THROTTLE | Integer | 100 | Limits the number of concurrent pushes allowed. On larger machines this can be increased for faster pushes |
PILOT_REMOTE_CLUSTER_TIMEOUT | Time Duration | 30s | After this timeout expires, pilot can become ready without syncing data from clusters added via remote-secrets. Setting the timeout to 0 disables this behavior. |
PILOT_SCOPE_GATEWAY_TO_NAMESPACE | Boolean | false | If 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_SIDECAR_USE_REMOTE_ADDRESS | Boolean | false | UseRemoteAddress sets useRemoteAddress to true for side car outbound listeners. |
PILOT_SKIP_VALIDATE_TRUST_DOMAIN | Boolean | false | Skip validating the peer is from the same trust domain when mTLS is enabled in authentication policy |

PILOT_USE_ENDPOINT_SLICE | Boolean | false | If enabled, Pilot will use EndpointSlices as the source of endpoints for Kubernetes services. By default, this is false, and Endpoints will be used. This requires the Kubernetes EndpointSlice controller to be enabled. Currently this is mutual exclusive - either Endpoints or EndpointSlices will be used |
PILOT_WORKLOAD_ENTRY_GRACE_PERIOD | Time Duration | 10s | The amount of time an auto-registered workload can remain disconnected from all Pilot instances before the associated WorkloadEntry is cleaned up. |
PILOT_XDS_CACHE_SIZE | Integer | 20000 | The maximum number of cache entries for the XDS cache. |
PILOT_XDS_CACHE_STATS | Boolean | false | If true, Pilot will collect metrics for XDS cache efficiency. |

SHARED_MESH_CONFIG | String | | Additional config map to load for shared MeshConfig settings. The standard mesh config will take precedence. |
SPIFFE_BUNDLE_ENDPOINTS | String | | The SPIFFE bundle trust domain to endpoint mappings. Istiod retrieves the root certificate from each SPIFFE bundle endpoint and uses it to verify client certifiates from that trust domain. The endpoint must be compliant to the SPIFFE Bundle Endpoint standard. For details, please refer to https://github.com/spiffe/spiffe/blob/master/standards/SPIFFE_Trust_Domain_and_Bundle.md . No need to configure this for root certificates issued via Istiod or web-PKI based root certificates. Use || between <trustdomain, endpoint> tuples.
