failureThreshold int32 Minimum consecutive failures for the probe to be considered failed after having succeeded. Defaults to 3 seconds.
httpGet istio.networking.v1alpha3.HTTPHealthCheckConfig httpGet is performed to a given endpoint and the status/able to connect determines health.
tcpSocket istio.networking.v1alpha3.TCPHealthCheckConfig Health is determined by if the proxy is able to connect.
exec istio.networking.v1alpha3.ExecHealthCheckConfig Health is determined by how the command that is executed exited.

WorkloadGroup

Field Type Label Description
metadata istio.networking.v1alpha3.WorkloadGroup.ObjectMeta Metadata that will be used for all corresponding WorkloadEntries. User labels for a workload group should be set here in metadata rather than in template.
template istio.networking.v1alpha3.WorkloadEntry Template to be used for the generation of WorkloadEntry resources that belong to this WorkloadGroup. Please note that address and labels fields should not be set in the template, and an empty serviceAccount should default to default. The workload identities (mTLS certificates) will be bootstrapped using the specified service account's token. Workload entries in this group will be in the same namespace as the workload group, and inherit the labels and annotations from the above metadata field.
probe istio.networking.v1alpha3.ReadinessProbe ReadinessProbe describes the configuration the user must provide for healthchecking on their workload. This configuration mirrors K8S in both syntax and logic for the most part.
