Description Maciej Szulik 2019-05-08 14:03:07 UTC
Currently you need to explicitly pass pod name to connect to when invoking oc rsh. Upstream updated kubectl exec [1] to work with resource/name format. We want to go one step further and support -f which reads a resource from a file and work against it. For that we need to update ExecOptions (core of kubectl exec) which is then used inside oc rsh.

Comment 2 Maciej Szulik 2019-09-25 08:24:31 UTC
This will be fixed with k8s 1.16 bump from https://github.com/openshift/oc/pull/102

Comment 3 Michal Fojtik 2019-09-30 08:58:33 UTC
The 1.16 landed in oc, moving to QA

Comment 5 Xingxing Xia 2019-10-14 10:05:05 UTC
Unpack oc from latest http://download-node-02.eng.bos.redhat.com/rcm-guest/puddles/RHAOS/AtomicOpenShift/4.3/v4.3.0-201910140317_2019-10-14.2/x86_64/os/Packages/ openshift-clients-4.3.0-201910101400.git.1.fe72907.el7.x86_64.rpm and check, no -f flag:
$ ./oc version -o yaml

Comment 7 Sally 2019-11-26 21:10:01 UTC
The upstream change of `Upstream updated kubectl exec to work with resource/name format` is what was picked up with k8s 1.16 bump.  The additional desired change of allowing to pass a '-f filename' will be an additional upstream PR, I'm moving this bug to 4.4, since the upstream PR will be required.
