`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_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_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_MONGO_FILTER`	Boolean	`true`	EnableMongoFilter enables injection of `envoy.filters.network.mongo_proxy` in the filter chain.
`PILOT_ENABLE_MYSQL_FILTER`	Boolean	`false`	EnableMysqlFilter enables injection of `envoy.filters.network.mysql_proxy` in the filter chain.
`PILOT_ENABLE_PROTOCOL_SNIFFING_FOR_INBOUND`	Boolean	`true`	If enabled, protocol sniffing will be used for inbound listeners whose port protocol is not specified or unsupported

`PILOT_ENVOY_FILTER_STATS`	Boolean	`false`	If true, Pilot will collect metrics for envoy filter operations.
`PILOT_FILTER_GATEWAY_CLUSTER_CONFIG`	Boolean	`false`
`PILOT_FLOW_CONTROL_TIMEOUT`	Time Duration	`15s`	If set, the max amount of time to delay a push by. Depends on PILOT_ENABLE_FLOW_CONTROL.
`PILOT_HTTP10`	Boolean	`false`	Enables the use of HTTP 1.0 in the outbound HTTP listeners, to support legacy applications.
`PILOT_HTTP_DELAYED_CLOSE_TIMEOUT`	Time Duration	`1s`	The delayed close timeout is for downstream HTTP connections. This should be set to a high value or disable it when peer is reading large chunk of data and to give an opportunity to initiate the close sequence properly. A value of 0s disables this
`PILOT_INBOUND_PROTOCOL_DETECTION_TIMEOUT`	Time Duration	`1s`	Protocol detection timeout for inbound listener
`PILOT_JWT_ENABLE_REMOTE_JWKS`	Boolean	`false`	If enabled, checks to see if the configured JwksUri in RequestAuthentication is a mesh cluster URL and configures Remote Jwks to let Envoy fetch the Jwks instead of Istiod.
`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_USE_TARGET_PORT_FOR_GATEWAY_ROUTES`	Boolean	`true`	If true, routes will use the target port of the gateway service in the route name, not the service port.
`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.

`POD_NAME`	String
`REQUIRE_3P_TOKEN`	Boolean	`false`	Reject k8s default tokens, without audience. If false, default K8S token will be accepted
`REWRITE_PROBE_LEGACY_LOCALHOST_DESTINATION`	Boolean	`false`	If enabled, readiness probes will be sent to ‘localhost’. Otherwise, they will be sent to the Pod’s IP, matching Kubernetes’ behavior.
`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.
