Description Miciah Dashiel Butler Masters 2020-01-24 01:21:05 UTC

Description of problem:

When I try to use `oc rsh` to open a shell to a deployment, it fails and prints "error: remote shell for deployments.apps is not supported".


Version-Release number of selected component (if applicable):

The failure can be reproduced on both 4.4.0-0.ci-2020-01-21-134224 and 4.4.0-0.ci-2020-01-23-204118.


How reproducible:

Consistently.


Steps to Reproduce:
1. Launch a 4.4 cluster.
2. Run `oc -n openshift-ingress rsh deploy/router-default`.


Actual results:

The `oc rsh` command fails on 4.4:

    % oc adm release extract --command=oc registry.svc.ci.openshift.org/ocp/release:4.4.0-0.ci-2020-01-23-204118
    oc adm release extract --command=oc   1.51s user 1.38s system 18% cpu 15.415 total
    % ./oc version
    Client Version: v4.2.0-alpha.0-386-g2dc71a4
    Server Version: 4.4.0-0.ci-2020-01-23-204118
    Kubernetes Version: v1.17.1
    % ./oc -n openshift-ingress rsh deploy/router-default
    error: remote shell for deployments.apps is not supported
    zsh: exit 1     ./oc -n openshift-ingress rsh deploy/router-default
    % 


Expected results:

The `oc rsh` command should succeed, as it does on a 4.3 cluster:

    % oc adm release extract --command=oc registry.svc.ci.openshift.org/ocp/release:4.3.0-0.ci-2020-01-21-121240
    oc adm release extract --command=oc   1.30s user 1.17s system 13% cpu 18.392 total
    % ./oc version
    Client Version: v4.2.0-alpha.0-295-g6a937df
    Server Version: 4.3.0-0.ci-2020-01-21-121240
    Kubernetes Version: v1.16.2
    % ./oc -n openshift-ingress rsh deploy/router-default
    sh-4.2$

Comment 2 Mike Fiedler 2020-01-31 20:45:51 UTC

Verified - oc rsh to deployment works fine:

[root@ip-172-31-53-199 tmp]# oc version

[root@ip-172-31-53-199 tmp]# oc get clusterversion
