Since v1.4.0, Longhorn replaced the in-house support bundle generation with a general-purpose support bundle kit.
You can click the
Generate Support Bundle at the bottom of Longhorn UI to download a zip file containing cluster manifests and logs.
During support bundle generation, Longhorn will create a Deployment for the support bundle manager.
Note: The support bundle manager will use a dedicated
longhorn-support-bundleservice account and
longhorn-support-bundlecluster role binding with
cluster-adminaccess for bundle collection.
With the support bundle, you can simulate a mocked Kubernetes cluster that is interactable with the
kubectl command. See simulator command for more details.
Longhorn currently does not support concurrent generation of multiple support bundles. We recommend waiting until the completion of the ongoing support bundle before initiating a new one. If a new support bundle is created while another one is still in progress, Longhorn will overwrite the older support bundle.
