Red Hat Bugzilla – Bug 1577520
Error message is wrong when disconnected from the internet
Last modified: 2018-10-11 03:19:39 EDT
When disconnected from the server (wifi off): $ oc get cm/ci-operator-image-registry -n ci error: the server doesn't have a resource type "cm" We're eating an error too early during discovery incorrectly. This is marked high severity because from a usability perspective it's completely the wrong class of error and doesn't point the user anywhere near the problem. It's potentially deferrable.
I cannot reproduce by disconnecting the network: $ oc version oc v3.10.0-0.38.0 ... Server https://api.free-int...:443 ... Then make the wire unplugged and wifi off, I got below output. $ oc get cm/myconfigmap -n xxia-proj The connection to the server api.free-int...:443 was refused - did you specify the right host or port? PS: there are bug 1538488 and bug 1529482 showing same "the server doesn't have a resource type" error. Maybe you hit one condition of them? :)
Can confirm that I receive the same results as comment 1 when disconnected from the internet. Which version of `oc` are you using?
I was finally able to reproduce this locally. Steps taken: 1. brought up a cluster using `oc cluster up --tag 1.10.0` 2. tested `oc get` successfully with a few resources: `oc get dc`, `oc get deploymentconfigs`, etc. 3. brought cluster down, without disconnecting from the internet: `oc cluster down` 4. tested `oc get` again: ``` $ oc get dc error: the server doesn't have a resource type "dc" $ oc get rc error: the server doesn't have a resource type "rc" $ oc get po error: the server doesn't have a resource type "po" ``` The restmapping error only occurred when getting resources by their alias. Providing the full resource name returned the correct error: ``` $ oc get deploymentconfigs The connection to the server 127.0.0.1:8443 was refused - did you specify the right host or port? ``` ``` $ oc get pods The connection to the server 127.0.0.1:8443 was refused - did you specify the right host or port? ``` The actual error is getting squashed here: https://github.com/openshift/origin/blob/master/vendor/k8s.io/kubernetes/pkg/kubectl/cmd/util/factory_object_mapping.go#L93 I was able to reproduce this with kubectl 1.9 and 1.10. This appears to have been fixed upstream in [1]. Will open a PR picking fix into Origin. 1. https://github.com/kubernetes/kubernetes/commit/ef0d1ab81927214db80c30d5af491f67546d790b#diff-382db7246643fb238d071e21dfedf623
Origin PR: https://github.com/openshift/origin/pull/19728
Tried ansible-installed env, when the env is down or deleted, it is same error: $ oc whoami -c # env installed days ago and already pruned today xxia-proj/ec2-...-compute-1-amazonaws-com:8443/xxia $ oc get bc error: the server doesn't have a resource type "bc"
*** Bug 1581634 has been marked as a duplicate of this bug. ***
I believe the code changes from comment 4 should now be in Origin. Moving in to ON_QA
Verified with ./oc version oc v3.11.0-0.4.0 kubernetes v1.11.0+d4cacc0 features: Basic-Auth GSSAPI Kerberos SPNEGO When the cluster is down or the network wire is unplugged, oc get with alias prompts "Unable to connect to the server ...". The issue is fixed.
