The pod resize e2e tests use memory limits as low as 20Mi for Guaranteed QoS pods. On OpenShift/CRI-O, the container runtime (runc) runs inside the pod's cgroup and requires ~20-22MB of memory during container creation and restart operations. This causes intermittent OOM kills when the pod's memory limit is at or below runc's memory footprint. This issue does not occur on containerd-based clusters because containerd's shim runs outside the pod's cgroup by default (ShimCgroup=""), so runc's memory is not charged against the pod's limit. Increase memory limits to provide sufficient headroom for runc: - originalMem: 20Mi -> 35Mi - reducedMem: 15Mi -> 30Mi - increasedMem: 25Mi -> 40Mi The test validates resize behavior, not minimal memory limits, so larger values do not reduce test coverage.

test/e2e
This is home to e2e tests used for presubmit, periodic, and postsubmit jobs.
Some of these jobs are merge-blocking, some are release-blocking.
e2e test ownership
All e2e tests must adhere to the following policies:
- the test must be owned by one and only one SIG
- the test must live in/underneath a sig-owned package matching pattern:
test/e2e/[{subpath}/]{sig}/..., e.g.test/e2e/auth- all tests owned by sig-authtest/e2e/common/storage- all testscommonto cluster-level and node-level e2e tests, owned by sig-nodetest/e2e/upgrade/apps- all tests used inupgradetesting, owned by sig-apps
- each sig-owned package should have an OWNERS file defining relevant approvers and labels for the owning sig, e.g.
# test/e2e/node/OWNERS
# See the OWNERS docs at https://go.k8s.io/owners
approvers:
- alice
- bob
- cynthia
emeritus_approvers:
- dave
reviewers:
- sig-node-reviewers
labels:
- sig/node
- packages that use
{subpath}should have animports.gofile importing sig-owned packages (for ginkgo's benefit), e.g.
// test/e2e/common/imports.go
package common
import (
// ensure these packages are scanned by ginkgo for e2e tests
_ "k8s.io/kubernetes/test/e2e/common/network"
_ "k8s.io/kubernetes/test/e2e/common/node"
_ "k8s.io/kubernetes/test/e2e/common/storage"
)
- test ownership must be declared via a top-level SIGDescribe call defined in the sig-owned package, e.g.
// test/e2e/lifecycle/framework.go
package lifecycle
import "k8s.io/kubernetes/test/e2e/framework"
// SIGDescribe annotates the test with the SIG label.
var SIGDescribe = framework.SIGDescribe("cluster-lifecycle")
// test/e2e/lifecycle/bootstrap/bootstrap_signer.go
package bootstrap
import (
"github.com/onsi/ginkgo"
"k8s.io/kubernetes/test/e2e/lifecycle"
)
var _ = lifecycle.SIGDescribe("cluster", feature.BootstrapTokens, func() {
/* ... */
ginkgo.It("should sign the new added bootstrap tokens", func(ctx context.Context) {
/* ... */
})
/* etc */
})
These polices are enforced:
- via the merge-blocking presubmit job
pull-kubernetes-verify - which ends up running
hack/verify-e2e-test-ownership.sh - which can also be run via
make verify WHAT=e2e-test-ownership
