Such command hangs: $ oc debug node/node-name -- /bin/missing param1 param2 User does not see any feedback why command hangs. In fact pod fails to start due to missing executable. I suggest `oc` checks pod status and fails early in case pod fails to start for whatever reason. Also exit with proper error message to the user. – Client Version: v4.2.0
Confirmed with latest oc client, the issue has fixed: [root@dhcp-140-138 ~]# oc version -o yaml clientVersion: buildDate: "2020-02-13T22:50:14Z" compiler: gc gitCommit: 5d7a12f03389b03b651f963cb5ee8ddfa9cff559 gitTreeState: clean gitVersion: v4.4.0 goVersion: go1.13.4 major: "" minor: "" platform: linux/amd64 [root@dhcp-140-138 ~]# oc debug node/ip-xxxxxx -- /bin/missing param1 param2 Starting pod/ip-xxxxxx-debug ...
