istioctl experimental authz

Commands to inspect and interact with the authorization policiescheck - check Envoy config dump for authorization configurationconvert - convert v1alpha1 RBAC policies to v1beta1 authorization policies

Examples

  # Check Envoy authorization configuration for pod httpbin-88ddbcfdd-nt5jb:
  istioctl x authz check httpbin-88ddbcfdd-nt5jb
  # Convert the v1alpha1 RBAC policies in the current cluster to v1beta1 authorization policies:
  istioctl x authz convert > v1beta1-authz.yaml

istioctl experimental authz check

Check reads the Envoy config dump and checks the filter configurationrelated to authorization. For example, it shows whether or not the Envoy is configuredwith authorization and the rules used in the authorization.

The Envoy config dump could be provided either by pod name or from a config dump file(the whole output of http://localhost:15000/config_dump of an Envoy instance).

THIS COMMAND IS STILL UNDER ACTIVE DEVELOPMENT AND NOT READY FOR PRODUCTION USE.

istioctl experimental authz check <pod-name>[.<pod-namespace>] [flags]

Examples

  # Check Envoy authorization configuration for pod httpbin-88ddbcfdd-nt5jb:
  istioctl x authz check httpbin-88ddbcfdd-nt5jb
  # Check Envoy authorization configuration from a config dump file:
  istioctl x authz check -f httpbin_config_dump.json

istioctl experimental authz convert

Convert Istio v1alpha1 RBAC policy to v1beta1 authorization policy. The command talks to KubernetesAPI server to get all the information needed to complete the conversion, including the v1alpha1 RBAC policies in the currentcluster, the Istio config-map for root namespace configuration and the k8s Service translating theservice name to workload selector.

The tool can also be used in offline mode without talking to the Kubernetes API server. In this mode,all needed information is provided through the command line.

Note: The converter tool makes a best effort attempt to keep the syntax unchanged whenconverting v1alph1 RBAC policy to v1beta1 policy. However, in some cases, strictmapping with equivalent syntax is not possible (e.g., constraints no longer validin the new workload oriented model, converting a service name containing a wildcardto workload selector).

Please always review the converted policies before applying them.

THIS COMMAND IS STILL UNDER ACTIVE DEVELOPMENT AND NOT READY FOR PRODUCTION USE.

istioctl experimental authz convert [flags]

Examples

  # Convert the v1alpha1 RBAC policy in the current cluster:
  istioctl x authz convert > v1beta1-authz.yaml
  # Convert the v1alpha1 RBAC policy provided through command line: 
  istioctl x authz convert -f v1alpha1-policy-1.yaml,v1alpha1-policy-2.yaml

istioctl experimental metrics

Prints the metrics for the specified service(s) when running in Kubernetes.

This command finds a Prometheus pod running in the specified istio systemnamespace. It then executes a series of queries per requested workload tofind the following top-level workload metrics: total requests per second,error rate, and request latency at p50, p90, and p99 percentiles. Thequery results are printed to the console, organized by workload name.

All metrics returned are from server-side reports. This means that latenciesand error rates are from the perspective of the service itself and not of anindividual client (or aggregate set of clients). Rates and latencies arecalculated over a time interval of 1 minute.

istioctl experimental metrics <workload name>...

istioctl experimental m <workload name>...

Examples

# Retrieve workload metrics for productpage-v1 workload

istioctl experimental wait [flags] <type> <name>[.<namespace>]

istioctl kube-inject

kube-inject manually injects the Envoy sidecar into Kubernetesworkloads. Unsupported resources are left unmodified so it is safe torun kube-inject over a single file that contains multiple Service,ConfigMap, Deployment, etc. definitions for a complex application. It'sbest to do this when the resource is initially created.

k8s.io/docs/concepts/workloads/pods/pod-overview/#pod-templates isupdated for Job, DaemonSet, ReplicaSet, Pod and Deployment YAML resourcedocuments. Support for additional pod-based resource types can beadded as necessary.

The Istio project is continually evolving so the Istio sidecarconfiguration may change unannounced. When in doubt re-run istioctlkube-inject on deployments to get the most up-to-date changes.

istioctl kube-inject [flags]

Examples

# Update resources on the fly before applying.

# Update an existing deployment.
kubectl get deployment -o yaml | istioctl kube-inject -f - | kubectl apply -f -
