pilot-agent completion bash

Generate the autocompletion script for the bash shell.

This script depends on the 'bash-completion' package. If it is not installed already, you can install it via your OS's package manager.

To load completions in your current shell session:

source <(pilot-agent completion bash)

To load completions for every new session, execute once:

#### Linux:

pilot-agent completion bash > /etc/bash_completion.d/pilot-agent

#### macOS:

pilot-agent completion bash > $(brew --prefix)/etc/bash_completion.d/pilot-agent

You will need to start a new shell for this setup to take effect.

Environment variables

These environment variables affect the behavior of the pilot-agent command. Please use with caution as these environment variables are experimental and can change anytime.
Variable NameTypeDefault ValueDescription
CA_ADDRStringAddress of the spiffe certificate provider. Defaults to discoveryAddress
CA_PROVIDERStringCitadelname of authentication provider
CA_ROOT_CAStringExplicitly set the root CA to expect for the CA connection.
CA_TRUSTED_NODE_ACCOUNTSStringIf 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_DOMAINStringThe cert signer domain info
CLOUD_PLATFORMStringCloud 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_IDStringKubernetesDefines the cluster and service registry that this Istiod instance belongs to
COMPLIANCE_POLICYStringIf 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).
CREDENTIAL_FETCHER_TYPEStringJWTThe type of the credential fetcher. Currently supported types include GoogleComputeEngine
CREDENTIAL_IDENTITY_PROVIDERStringGoogleComputeEngineThe identity provider for credential. Currently default supported identity provider is GoogleComputeEngine
DISABLE_ENVOYBooleanfalseDisables all Envoy agent features.
DNS_FORWARD_PARALLELBooleanfalseIf set to true, agent will send parallel DNS queries to all upstream nameservers
DNS_PROXY_ADDRStringlocalhost:15053Custom address for the DNS proxy. If it ends with :53 and running as root allows running without iptable DNS capture
DRY_RUN_FILE_PATHStringIf provided, StdoutStubDependencies will write the input from stdin to the given file.
ECC_CURVEStringP256The elliptic curve to use when ECC_SIGNATURE_ALGORITHM is set to ECDSA
ECC_SIGNATURE_ALGORITHMStringThe type of ECC signature algorithm to use when generating private keys
ENABLE_AUTO_SNIBooleantrueIf enabled, automatically set SNI when `DestinationRules` do not specify the same
ENABLE_CA_SERVERBooleantrueIf this is set to false, will not create CA server in istiod.
ENABLE_DEBUG_ON_HTTPBooleantrueIf this is set to false, the debug interface will not be enabled, recommended for production
ENABLE_ENHANCED_RESOURCE_SCOPINGBooleantrueIf 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_ALIASBooleantrueIf 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_NETWORKSBooleanfalseIf enable, endpoints defined in mesh networks will be configured as internal addresses in Http Connection Manager
ENABLE_LEADER_ELECTIONBooleantrueIf 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_EXPORTBooleanfalseIf 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_LOCALBooleanfalseIf 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_HOSTBooleanfalseIf 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_DISCOVERYBooleanfalseIf 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_HEADLESSBooleantrueIf true, the DNS name table for a headless service will resolve to same-network endpoints in any cluster.
ENABLE_NATIVE_SIDECARSBooleanfalseIf set, used Kubernetes native Sidecar container support. Requires SidecarContainer feature flag.
ENABLE_OPTIMIZED_CONFIG_REBUILDBooleantrueIf enabled, pilot will only rebuild config for resources that have changed
ENABLE_OTEL_BUILTIN_RESOURCE_LABELSBooleanfalseIf enabled, envoy will send builtin labels(e.g. node_name) via OTel sink.
ENABLE_PROBE_KEEPALIVE_CONNECTIONSBooleanfalseIf 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_RESOLUTION_NONE_TARGET_PORTBooleantrueIf enabled, targetPort will be supported for resolution=NONE ServiceEntry
ENABLE_SELECTOR_BASED_K8S_GATEWAY_POLICYBooleantrueIf disabled, Gateway API gateways will ignore workloadSelector policies, onlyapplying policies that select the gateway with a targetRef.
ENABLE_TLS_ON_SIDECAR_INGRESSBooleanfalseIf enabled, the TLS configuration on Sidecar.ingress will take effect
ENABLE_VTPROTOBUFBooleantrueIf true, will use optimized vtprotobuf based marshaling. Requires a build with -tags=vtprotobuf.
ENVOY_PROMETHEUS_PORTInteger15090Envoy prometheus redirection port value
ENVOY_STATUS_PORTInteger15021Envoy health status port value
ENVOY_USERStringistio-proxyEnvoy proxy username

INJECTION_WEBHOOK_CONFIG_NAMEStringistio-sidecar-injectorName of the mutatingwebhookconfiguration to patch, if istioctl is not used.
INSTANCE_IPString
IPTABLES_TRACE_LOGGINGBooleanfalseWhen enable, all iptables actions will be logged. This requires NET_ADMIN privilege and has noisy logs; as a result, this is intended for debugging only
ISTIOD_CUSTOM_HOSTStringCustom host name of istiod that istiod signs the server cert. Multiple custom host names are supported, and multiple values are separated by commas.
ISTIOD_SANStringOverride the ServerName used to validate Istiod certificate. Can be used as an alternative to setting /etc/hosts for VMs - discovery address will be an IP:port

ISTIO_BOOTSTRAPString
ISTIO_BOOTSTRAP_OVERRIDEString
ISTIO_CPU_LIMITInteger0CPU limit for the current process. Expressed as an integer value, rounded up.
ISTIO_DELTA_XDSBooleantrueIf 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_OUTBOUND_OWNER_GROUPS_EXCLUDEStringComma 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_ANNOTATIONSString
ISTIO_WATCH_NAMESPACEStringIf set, limit Kubernetes watches to a single namespace. Warning: only a single namespace can be set.
ISTIO_WORKLOAD_ENTRY_VALIDATE_IDENTITYBooleantrueIf enabled, will validate the identity of a workload matches the identity of the WorkloadEntry it is associating with for health checks and auto registration. This flag is added for backwards compatibility only and will be removed in future releases
