Description OpenShift BugZilla Robot 2021-11-18 15:48:52 UTC
+++ This bug was initially created as a clone of Bug #2023631 +++

While running the test
[sig-devex][Feature:Templates] templateinstance security tests  should pass security tests [Suite:openshift/conformance/parallel]

the following error can sometimes be observed

[AfterEach] [sig-devex][Feature:Templates] templateinstance security tests
  github.com/openshift/origin/test/extended/util/client.go:141
STEP: Destroying namespace "e2e-test-templates-vpqzv" for this suite.
fail [github.com/openshift/origin/test/extended/util/client.go:524]: Nov 15 22:41:04.835: invalid configuration: no configuration has been provided, try setting KUBERNETES_MASTER environment variable

failed: (7.3s) 2021-11-15T22:41:07 "[sig-devex][Feature:Templates] templateinstance security tests  should pass security tests [Suite:openshift/conformance/parallel]"

--- Additional comment from derekh on 2021-11-16 08:58:59 UTC ---

This can be reproduced by running the templateinstance test in parallel with the test 
"[sig-cli] oc adm storage-admin [Suite:openshift/conformance/parallel]"

The problem is that this test runs the command
oc new-project <snip/> policy-can-i

This command rewrites the kubeconfig file to change the current/default project,
while rewriting it the config files is zero length for a brief moment,

if another test reads this file while it is zero length then the other test will fail

This appears to be the case of any test that calls CLI.UserConfig() or CLI.AdminConfig()


Also the changing of context of the global kubeconfig could cause any test to fail
that expects it to remain at a specific context during the test.

Looks like a failure in last nights nightly was caused by this

Reassigning to Test Framework who own the OCP testsuite

Comment 2 Derek Higgins 2021-11-29 09:26:05 UTC
Setting to verified based on observed improvements in 4.10 ci results.
