Claudiu Belu f9e4a015e2 tests: Spawn poststart / prestop pods on the same node as the http pod
In the case of multinode clusters, the http server pod and the test cluster can
spawn on different nodes, which can be problematic for  poststart / prestop hooks,
as they are executed by the kubelet itself, and the cross-node lifecycle hook might
fail (according to the Kubernetes network model, it is not mandatory for kubelet to
be able to access pods on a different node).

This commit ensures that the test pod spawns on the same node as the http server pod.

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-auth
    • test/e2e/common/storage - all tests common to cluster-level and node-level e2e tests, owned by sig-node
    • test/e2e/upgrade/apps - all tests used in upgrade testing, 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 an imports.go file 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 "github.com/onsi/ginkgo"

// SIGDescribe annotates the test with the SIG label.
func SIGDescribe(text string, body func()) bool {
	return ginkgo.Describe("[sig-cluster-lifecycle] "+text, body)
}
// test/e2e/lifecycle/bootstrap/bootstrap_signer.go

package bootstrap

import (
	"github.com/onsi/ginkgo"
	"k8s.io/kubernetes/test/e2e/lifecycle"
)
var _ = lifecycle.SIGDescribe("[Feature:BootstrapTokens]", func() {
  /* ... */
  ginkgo.It("should sign the new added bootstrap tokens", func() {
    /* ... */
  })
  /* 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
