Environment variables
These environment variables affect the behavior of the pilot-discovery command. Please use with caution as these environment variables are experimental and can change anytime.
| Variable Name | Type | Default Value | Description |
|---|---|---|---|
AUDIENCE | String | | Expected audience in the tokens. |
CA_TRUSTED_NODE_ACCOUNTS | String | | If set, the list of service accounts that are allowed to use node authentication for CSRs. Node authentication allows an identity to create CSRs on behalf of other identities, but only if there is a pod running on the same node with that identity. This is intended for use with node proxies. |
CERT_SIGNER_DOMAIN | String | | The cert signer domain info |
CITADEL_ENABLE_JITTER_FOR_ROOT_CERT_ROTATOR | Boolean | true | If 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_TTL | Time Duration | 87600h0m0s | The TTL of self-signed CA root certificate. |
CITADEL_SELF_SIGNED_CA_RSA_KEY_SIZE | Integer | 2048 | Specify the RSA key size to use for self-signed Istio CA certificates. |
CITADEL_SELF_SIGNED_ROOT_CERT_CHECK_INTERVAL | Time Duration | 1h0m0s | The 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_PERCENTILE | Integer | 20 | Grace period percentile for self-signed root cert. |
CLOUD_PLATFORM | String | | Cloud Platform on which proxy is running, if not specified, Istio will try to discover the platform. Valid platform values are aws, azure, gcp, none |
CLUSTER_ID | String | Kubernetes | Defines the cluster and service registry that this Istiod instance belongs to |
COMPLIANCE_POLICY | String | | If set, applies policy-specific restrictions over all existing TLS settings, including in-mesh mTLS and external TLS. Valid values are: ‘’ or unset places no additional restrictions. ‘fips-140-2’ which enforces a version of the TLS protocol and a subset of cipher suites overriding any user preferences or defaults for all runtime components, including Envoy, gRPC Go SDK, and gRPC C++ SDK. WARNING: Setting compliance policy in the control plane is a necessary but not a sufficient requirement to achieve compliance. There are additional steps necessary to claim compliance, including using the validated cryptograhic modules (please consult https://www.envoyproxy.io/docs/envoy/latest/intro/arch_overview/security/ssl#fips-140-2). |
DEFAULT_WORKLOAD_CERT_TTL | Time Duration | 24h0m0s | The default TTL of issued workload certificates. Applied when the client sets a non-positive TTL in the CSR. |
ENABLE_AUTO_SNI | Boolean | true | If enabled, automatically set SNI when DestinationRules do not specify the same |
ENABLE_CA_SERVER | Boolean | true | If this is set to false, will not create CA server in istiod. |
ENABLE_DEBUG_ON_HTTP | Boolean | true | If this is set to false, the debug interface will not be enabled, recommended for production |
ENABLE_ENHANCED_RESOURCE_SCOPING | Boolean | false | If enabled, meshConfig.discoverySelectors will limit the CustomResource configurations(like Gateway,VirtualService,DestinationRule,Ingress, etc)that can be processed by pilot. This will also restrict the root-ca certificate distribution. |
ENABLE_EXTERNAL_NAME_ALIAS | Boolean | true | If enabled, ExternalName Services will be treated as simple aliases: anywhere where we would match the concrete service, we also match the ExternalName. In general, this mirrors Kubernetes behavior more closely. However, it means that policies (routes and DestinationRule) cannot be applied to the ExternalName service. If disabled, ExternalName behaves in fairly unexpected manner. Port matters, while it does not in Kubernetes. If it is a TCP port, all traffic on that port will be matched, which can have disastrous consequences. Additionally, the destination is seen as an opaque destination; even if it is another service in the mesh, policies such as mTLS and load balancing will not be used when connecting to it. |
ENABLE_HCM_INTERNAL_NETWORKS | Boolean | false | If enable, endpoints defined in mesh networks will be configured as internal addresses in Http Connection Manager |
ENABLE_LEADER_ELECTION | Boolean | true | If enabled (default), starts a leader election client and gains leadership before executing controllers. If false, it assumes that only one instance of istiod is running and skips leader election. |
ENABLE_MCS_AUTO_EXPORT | Boolean | false | If enabled, istiod will automatically generate Kubernetes Multi-Cluster Services (MCS) ServiceExport resources for every service in the mesh. Services defined to be cluster-local in MeshConfig are excluded. |
ENABLE_MCS_CLUSTER_LOCAL | Boolean | false | If enabled, istiod will treat the host <svc>.<namespace>.svc.cluster.local as defined by the Kubernetes Multi-Cluster Services (MCS) spec. In this mode, requests to cluster.local will be routed to only those endpoints residing within the same cluster as the client. Requires that both ENABLE_MCS_SERVICE_DISCOVERY and ENABLE_MCS_HOST also be enabled. |
ENABLE_MCS_HOST | Boolean | false | If enabled, istiod will configure a Kubernetes Multi-Cluster Services (MCS) host (<svc>.<namespace>.svc.clusterset.local) for each service exported (via ServiceExport) in at least one cluster. Clients must, however, be able to successfully lookup these DNS hosts. That means that either Istio DNS interception must be enabled or an MCS controller must be used. Requires that ENABLE_MCS_SERVICE_DISCOVERY also be enabled. |
ENABLE_MCS_SERVICE_DISCOVERY | Boolean | false | If enabled, istiod will enable Kubernetes Multi-Cluster Services (MCS) service discovery mode. In this mode, service endpoints in a cluster will only be discoverable within the same cluster unless explicitly exported via ServiceExport. |
ENABLE_MULTICLUSTER_HEADLESS | Boolean | true | If true, the DNS name table for a headless service will resolve to same-network endpoints in any cluster. |
ENABLE_NATIVE_SIDECARS | Boolean | false | If set, used Kubernetes native Sidecar container support. Requires SidecarContainer feature flag. |
ENABLE_OPTIMIZED_CONFIG_REBUILD | Boolean | true | If enabled, pilot will only rebuild config for resources that have changed |
ENABLE_OTEL_BUILTIN_RESOURCE_LABELS | Boolean | false | If enabled, envoy will send builtin labels(e.g. node_name) via OTel sink. |
ENABLE_PROBE_KEEPALIVE_CONNECTIONS | Boolean | false | If enabled, readiness probes will keep the connection from pilot-agent to the application alive. This mirrors older Istio versions’ behaviors, but not kubelet’s. |
ENABLE_SELECTOR_BASED_K8S_GATEWAY_POLICY | Boolean | true | If disabled, Gateway API gateways will ignore workloadSelector policies, onlyapplying policies that select the gateway with a targetRef. |
ENABLE_TLS_ON_SIDECAR_INGRESS | Boolean | false | If enabled, the TLS configuration on Sidecar.ingress will take effect |
EXTERNAL_CA | String | | External CA Integration Type. Permitted value is ISTIOD_RA_KUBERNETES_API. |
EXTERNAL_ISTIOD | Boolean | false | If this is set to true, one Istiod will control remote clusters including CA. |
GCP_METADATA | String | | Pipe separated GCP metadata, schemed as PROJECT_ID|PROJECT_NUMBER|CLUSTER_NAME|CLUSTER_ZONE |
GCP_QUOTA_PROJECT | String | | Allows specification of a quota project to be used in requests to GCP APIs. |
GRPC_KEEPALIVE_INTERVAL | Time Duration | 30s | gRPC Keepalive Interval |
GRPC_KEEPALIVE_TIMEOUT | Time Duration | 10s | gRPC Keepalive Timeout |
HTTP_STRIP_FRAGMENT_FROM_PATH_UNSAFE_IF_DISABLED | Boolean | true | |
INBOUND_INTERCEPTION_MODE | String | | The mode used to redirect inbound connections to Envoy, either “REDIRECT” or “TPROXY” |
INBOUND_TPROXY_MARK | String | | |
INJECTION_WEBHOOK_CONFIG_NAME | String | istio-sidecar-injector | Name of the mutatingwebhookconfiguration to patch, if istioctl is not used. |
INJECT_ENABLED | Boolean | true | Enable mutating webhook handler. |
ISTIOD_CUSTOM_HOST | String | | Custom host name of istiod that istiod signs the server cert. Multiple custom host names are supported, and multiple values are separated by commas. |
ISTIO_AGENT_ENABLE_WASM_REMOTE_LOAD_CONVERSION | Boolean | true | If enabled, Istio agent will intercept ECDS resource update, downloads Wasm module, and replaces Wasm module remote load with downloaded local module file. |
ISTIO_BOOTSTRAP | String | | |
ISTIO_DELTA_XDS | Boolean | false | If enabled, pilot will only send the delta configs as opposed to the state of the world on a Resource Request. This feature uses the delta xds api, but does not currently send the actual deltas. |
ISTIO_DUAL_STACK | Boolean | false | If true, Istio will enable the Dual Stack feature. |
ISTIO_ENABLE_CONTROLLER_QUEUE_METRICS | Boolean | false | If enabled, publishes metrics for queue depth, latency and processing times. |
ISTIO_ENABLE_HTTP2_PROBING | Boolean | true | If enabled, HTTP2 probes will be enabled for HTTPS probes, following Kubernetes |
ISTIO_ENABLE_IPV4_OUTBOUND_LISTENER_FOR_IPV6_CLUSTERS | Boolean | false | If true, pilot will configure an additional IPv4 listener for outbound traffic in IPv6 only clusters, e.g. AWS EKS IPv6 only clusters. |
ISTIO_ENABLE_OPTIMIZED_SERVICE_PUSH | Boolean | true | If enabled, Istiod will not push changes on arbitrary annotation change. |

ISTIO_OUTBOUND_OWNER_GROUPS_EXCLUDE | String | | Comma separated list of groups whose outgoing traffic is to be excluded from redirection to Envoy. A group can be specified either by name or by a numeric GID. Only applies when traffic from all groups (i.e. “*”) is being redirected to Envoy. |
ISTIO_PROMETHEUS_ANNOTATIONS | String | | |
ISTIO_WATCH_NAMESPACE | String | | If set, limit Kubernetes watches to a single namespace. Warning: only a single namespace can be set. |
ISTIO_WORKLOAD_ENTRY_VALIDATE_IDENTITY | Boolean | true | If enabled, will validate the identity of a workload matches the identity of the WorkloadEntry it is associating with for health checks and auto registration.

PILOT_CONVERT_SIDECAR_SCOPE_CONCURRENCY | Integer | 1 | Used to adjust the concurrency of SidecarScope conversions. When istiod is deployed on a multi-core CPU server, increasing this value will help to use the CPU to accelerate configuration push, but it also means that istiod will consume more CPU resources. |
PILOT_DEBOUNCE_AFTER | Time Duration | 100ms | The delay added to config/registry events for debouncing. This will delay the push by at least this interval.
