how to extract keys not starting with /kubernetes.io/ ?

[ybrock]

Hi,

Is there a way to extract keys and values stored elsewhere than in /kubernetes.io/ ?

I try to extract everything from an etcd backup taken on Openshift with etcdctl snapshot , and auger gives a warning and does not produce output for keys other than the one starting by /kubernetes.io/. Is there a way to extract objects located in /openshift.io/ for example ?

I use :

auger extract -f $DBFILE --fields=key,value

to extract everything in the snapshot to backup my openshift clusters.

We can see that trying to extract a key outside /kubernetes.iodoes not succeed :

auger extract -f snapshot_2024-11-26_154401.db -k /openshift.io/routes/openshift-console/console
Error: error decoding from application/vnd.kubernetes.storagebinary: no kind "Route" is registered for version "route.openshift.io/v1" in scheme "pkg/runtime/scheme.go:100"

Am I missing something ?

Kind regards

Hi @ybrock,

auger uses APIs in k8s.io/apimachinery/pkg/runtime/schema to decode the data. In order to decode types outside /kubernetes.io, you would need to provide your own decoder in

auger/pkg/scheme/init.go
