The advantages of using a validation admission policy (VAP) are that no changes are needed in Kubernetes and that admins have full flexibility if and how they want to control which users are allowed to use "admin access" in their requests. The downside is that without admins taking actions, the feature is enabled out-of-the-box in a cluster. Documentation for DRA will have to make it very clear that something needs to be done in multi-tenant clusters. The test/e2e/testing-manifests/dra/admin-access-policy.yaml shows how to do this. The corresponding E2E tests ensures that it actually works as intended. For some reason, adding the namespace to the message expression leads to a type check errors, so it's currently commented out.
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
