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 > /usr/local/etc/bash_completion.d/pilot-agent

Environment variables

These environment variables affect the behavior of the pilot-agent command.
Variable NameTypeDefault ValueDescription
AMBIENT_ENABLE_STATUSBooleanfalseIf enabled, status messages for ambient mode will be written to resources. Currently, this does not do leader election, so may be unsafe to enable with multiple replicas.
BYPASS_OVERLOAD_MANAGER_FOR_STATIC_LISTENERSBooleantrueIf enabled, overload manager will not be applied to static listeners
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
