Istio must-gather

Istio must-gather is a tool built on top of OpenShift must-gather that expands its capabilities to gather Service Mesh information.

Usage

oc adm must-gather --image=quay.io/maistra/istio-must-gather:3.0

The command above will create a local directory with a dump of the OpenShift Service Mesh state. Note that this command will only get data related to the Service Mesh part of the OpenShift cluster.

You will get a dump of:

• The Sail Operator namespace (and its children objects)
• All Control Plane namespaces (and their children objects)
• All namespaces (and their children objects) that belong to any service mesh
• All Istio CRD definitions
• All Istio CRD objects (VirtualServices in a given namespace, etc)
• All Istio Webhooks
• All Sail operator CRD definitions
• All Sail operator CRD objects (Istio CNI, Istio, Istio Revision, etc.)
• All Kiali CRD definitions
• All Kiali CRD objects (Kiali, ossmconsole)

In order to get data about other parts of the cluster (not specific to service mesh) you should run just oc adm must-gather (without passing a custom image). Run oc adm must-gather -h to see more options.
