Guangrong, If you ssh into the rancher VM as root (same key), you will be able to run kubectl w/o problem. If you ssh as ubuntu then sudo to root to run kubectl, you will get the error msg you saw. An “export HOME=/root” will fix the problem.

Here's the screenshot of the error(s): [cid:[email protected]] I've tried the commands under different projects (Integration-SB-04, Integration-OOM-Staging-Daily and Integration-OOM-Daily). The same error occurred in all of them. Vijay's suggestion didn't seem to work for me. This is a little bit urgent because it's preventing me from completing the pairwise testing. Any help will be sincerely appreciated.

I just checked SB04 though and it looks k8s/kubectl are healthy; but the bootstrap pod you are trying to execute into though is not valid. vv770d@pod-onap-01-vjhost:~$ ssh -i ~/onap_dev [email protected]<mailto:[email protected]> ubuntu@onap-oom-rancher:~$ sudo su - root@onap-oom-rancher:~# kubectl get pods -n onap | grep bootstrap dev-dcaegen2-dcae-bootstrap-776cf86d49-ljqxm 1/1 Running 0 1d root@onap-oom-rancher:~# kubectl exec -it -n onap dev-dcaegen2-dcae-bootstrap-776cf86d49-ljqxm /bin/bash [root@dev-dcaegen2-dcae-bootstrap-776cf86d49-ljqxm /]# In some env, it was required explicitly to set home for kubectl to work – but dint need in SB04. export home=/root Also besides SB04, you could also check this on Integration-OOM-Staging-Daily/Integration-OOM-Daily environment tenant; they have full setup too – but they are torn down daily.

Guangrong Fu <[email protected]<mailto:[email protected]>>于2018年10月20日周六 上午11:05写道： Hi Vijay, Since I have no access to the DCAE project in the open lab, I tried to do something in SB04. But when I executed "kubectl" command, errors prompted. Such as: root@onap-oom-rancher:~# kubectl get pod -n onap error: couldn't get version/kind; json parse error: json: cannot unmarshal string into Go value of type struct { APIVersion string "json:\"apiVersion,omitempty\""; Kind string "json:\"kind,omitempty\"" } root@onap-oom-rancher:~# kubectl exec -it -n onap dev-dcaegen2-dcae-bootstrap-776cf86d49-mxzq6 /bin/bash error: serializer for text/html doesn't exist etc. Do you have any experience in this? I am contacting Stephen Gooch for help, but he didn't respond. Thanks, Guangrong -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.
