`policy.istio.io/check`	[Pod]	Determines the policy for behavior when unable to connect to Mixer. If not set, FAIL_CLOSE is set, rejecting requests.
`policy.istio.io/checkBaseRetryWaitTime`	[Pod]	Base time to wait between retries, will be adjusted by backoff and jitter. In duration format. If not set, this will be 80ms.
`policy.istio.io/checkMaxRetryWaitTime`	[Pod]	Maximum time to wait between retries to Mixer. In duration format. If not set, this will be 1000ms.
`policy.istio.io/checkRetries`	[Pod]	The maximum number of retries on transport errors to Mixer. If not set, this will be 0, indicating no retries.
`policy.istio.io/lang`	[Pod]	Selects the attribute expression language runtime for Mixer.
`readiness.status.sidecar.istio.io/applicationPorts`	[Pod]	Specifies the list of ports exposed by the application container. Used by the Envoy sidecar readiness probe to determine that Envoy is configured and ready to receive traffic.
`readiness.status.sidecar.istio.io/failureThreshold`	[Pod]	Specifies the failure threshold for the Envoy sidecar readiness probe.
`readiness.status.sidecar.istio.io/initialDelaySeconds`	[Pod]	Specifies the initial delay (in seconds) for the Envoy sidecar readiness probe.
`readiness.status.sidecar.istio.io/periodSeconds`	[Pod]	Specifies the period (in seconds) for the Envoy sidecar readiness probe.
`sidecar.istio.io/bootstrapOverride`	[Pod]	Specifies an alternative Envoy bootstrap configuration file.
`sidecar.istio.io/componentLogLevel`	[Pod]	Specifies the component log level for Envoy.
`sidecar.istio.io/controlPlaneAuthPolicy`	[Pod]	Specifies the auth policy used by the Istio control plane. If NONE, traffic will not be encrypted. If MUTUAL_TLS, traffic between Envoy sidecar will be wrapped into mutual TLS connections.
`sidecar.istio.io/discoveryAddress`	[Pod]	Specifies the XDS discovery address to be used by the Envoy sidecar.
`sidecar.istio.io/inject`	[Pod]	Specifies whether or not an Envoy sidecar should be automatically injected into the workload.
`sidecar.istio.io/interceptionMode`	[Pod]	Specifies the mode used to redirect inbound connections to Envoy (REDIRECT or TPROXY).
`sidecar.istio.io/logLevel`	[Pod]	Specifies the log level for Envoy.
`sidecar.istio.io/proxyCPU`	[Pod]	Specifies the requested CPU setting for the Envoy sidecar.
`sidecar.istio.io/proxyImage`	[Pod]	Specifies the Docker image to be used by the Envoy sidecar.
`sidecar.istio.io/proxyMemory`	[Pod]	Specifies the requested memory setting for the Envoy sidecar.
`sidecar.istio.io/rewriteAppHTTPProbers`	[Pod]	Rewrite HTTP readiness and liveness probes to be redirected to the Envoy sidecar.
`sidecar.istio.io/statsInclusionPrefixes`	[Pod]	Specifies the comma separated list of prefixes of the stats to be emitted by Envoy.
`sidecar.istio.io/statsInclusionRegexps`	[Pod]	Specifies the comma separated list of regexes the stats should match to be emitted by Envoy.
`sidecar.istio.io/statsInclusionSuffixes`	[Pod]	Specifies the comma separated list of suffixes of the stats to be emitted by Envoy.
`sidecar.istio.io/status`	[Pod]	Generated by Envoy sidecar injection that indicates the status of the operation. Includes a version hash of the executed template, as well as names of injected resources.
`sidecar.istio.io/userVolume`	[Pod]	Specifies one or more user volumes (as a JSON array) to be added to the Envoy sidecar.
`sidecar.istio.io/userVolumeMount`	[Pod]	Specifies one or more user volume mounts (as a JSON array) to be added to the Envoy sidecar.
`status.sidecar.istio.io/port`	[Pod]	Specifies the HTTP status Port for the Envoy sidecar. If zero, the sidecar will not provide status.
`traffic.sidecar.istio.io/excludeInboundPorts`	[Pod]	A comma separated list of inbound ports to be excluded from redirection to Envoy. Only applies when all inbound traffic (i.e. '*') is being redirected.
`traffic.sidecar.istio.io/excludeOutboundIPRanges`	[Pod]	A comma separated list of IP ranges in CIDR form to be excluded from redirection. Only applies when all outbound traffic (i.e. '*') is being redirected.
`traffic.sidecar.istio.io/excludeOutboundPorts`	[Pod]	A comma separated list of outbound ports to be excluded from redirection to Envoy.
`traffic.sidecar.istio.io/includeInboundPorts`	[Pod]	A comma separated list of inbound ports for which traffic is to be redirected to Envoy. The wildcard character '*' can be used to configure redirection for all ports. An empty list will disable all inbound redirection.
`traffic.sidecar.istio.io/includeOutboundIPRanges`	[Pod]	A comma separated list of IP ranges in CIDR form to redirect to Envoy (optional). The wildcard character '*' can be used to redirect all outbound traffic. An empty list will disable all outbound redirection.
`traffic.sidecar.istio.io/kubevirtInterfaces`	[Pod]	A comma separated list of virtual interfaces whose inbound traffic (from VM) will be treated as outbound.
