PILOT_DEBOUNCE_MAX | Time Duration | 10s | The 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_CONFIG | Boolean | false | |
PILOT_DISTRIBUTION_HISTORY_RETENTION | Time Duration | 1m0s | If enabled, Pilot will keep track of old versions of distributed config for this duration. |
PILOT_ENABLED_SERVICE_APIS | Boolean | false | If this is set to true, support for Kubernetes service-apis (github.com/kubernetes-sigs/service-apis) will be enabled. This feature is currently experimental, and is off by default. |
PILOT_ENABLE_ANALYSIS | Boolean | false | If enabled, pilot will run istio analyzers and write analysis errors to the Status field of any Istio Resources |
PILOT_ENABLE_CONFIG_DISTRIBUTION_TRACKING | Boolean | true | If 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_VALIDATION | Boolean | false | If 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_DEBOUNCE | Boolean | true | If 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_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_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_INCREMENTAL_MCP | Boolean | false | If enabled, pilot will set the incremental flag of the options in the mcp controller to true, and then galley may push data incrementally, it depends on whether the resource supports incremental. By default, this is false. |
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_ENABLE_STATUS | Boolean | false | If enabled, pilot will update the CRD Status field of all istio resources with reconciliation status. |
PILOT_ENABLE_TCP_METADATA_EXCHANGE | Boolean | true | If enabled, metadata exchange will be enabled for TCP using ALPN and Network Metadata Exchange filters in Envoy |
PILOT_ENABLE_THRIFT_FILTER | Boolean | false | EnableThriftFilter enables injection of envoy.filters.network.thrift_proxy in the filter chain. |
PILOT_ENABLE_VIRTUAL_SERVICE_DELEGATE | Boolean | false | If enabled, Pilot will merge virtual services with delegates. By default, this is false, and virtualService with delegate will be ignored |
PILOT_FILTER_GATEWAY_CLUSTER_CONFIG | Boolean | false | |
PILOT_HTTP10 | Boolean | false | Enables the use of HTTP 1.0 in the outbound HTTP listeners, to support legacy applications. |
PILOT_INBOUND_PROTOCOL_DETECTION_TIMEOUT | Time Duration | 1s | Protocol detection timeout for inbound listener |
PILOT_INITIAL_FETCH_TIMEOUT | Time Duration | 0s | Specifies 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_THROTTLE | Integer | 100 | Limits the number of concurrent pushes allowed. On larger machines this can be increased for faster pushes |
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_STATUS_QPS | Floating-Point | 100 | If status is enabled, controls the QPS with which status will be updated. See https://godoc.org/k8s.io/client-go/rest#Config QPS |
PILOT_TRACE_SAMPLING | Floating-Point | 100 | Sets the mesh-wide trace sampling percentage. Should be 0.0 - 100.0. Precision to 0.01. Default is 100, not recommended for production use. |
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 |
POD_NAMESPACE | String | istio-system | Namespace for the Mixer pod (Downward API). |
TERMINATION_DRAIN_DURATION_SECONDS | Integer | 5 | The 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. |
