NUMA Resources Operator test suite

The NUMA resources operator e2e suite can optionally setup/teardown the numaresources stack, but the suite expects a pre-configured kubeletconfig. Please find here an example of recommended kubeletconfig.

The e2e suite can set a default kubeletconfig, but this is not recommended. The recommended flow is to pre-configure the cluster with a kubeletconfig object. Should you decide to use the default kubeletconfig, please omit the -e E2E_NROP_INSTALL_SKIP_KC=true from all the podman command lines below.

The e2e suite assumes the cluster has the numaresources operator installed, but with no configuration. To install the numaresources operator, you can use the vehicle which best suits your use case (OLM, make deploy...).

In addition to kubelet config, refer to doc/examples directory for example specification files. NUMAResourcesOperator CR and NUMAResourcesScheduler CR must be deployed in the cluster. These CRs take care of deployment of Resouce Topology Exporter daemon (on nodes that are targetted by the machine config pool selector) and NUMA-aware scheduler plugin as a secondary scheduler plugin respective.

Running from the source tree

This is the easiest way, recommended for developers and people which want to consume the latest and greatest source tree. From the NUMA Resources Operator source tree:

export KUBECONFIG=...
./hack/run-test-serial-e2e.sh

To get all the options supported by the run script:

./hack/run-test-serial-e2e.sh --help

Running from container images

Pre-built container images are available which contain the full testsuite, to enable containerized flows.

To actually run the tests and the tests only, assuming a pre-configured numaresources stack

podman run -ti \
	-v $KUBECONFIG:/kubeconfig:z \
	-e KUBECONFIG=/kubeconfig
	-e E2E_NROP_INSTALL_SKIP_KC=true \
	quay.io/openshift-kni/numaresources-operator-tests:4.18.999-snapshot

To setup the stack from scratch and then run the tests (you may want to do that with ephemeral CI clusters)

podman run -ti \
	-v $KUBECONFIG:/kubeconfig:z \
	-e KUBECONFIG=/kubeconfig \
	-e E2E_NROP_INSTALL_SKIP_KC=true \
	quay.io/openshift-kni/numaresources-operator-tests:4.18.999-snapshot \
	--setup

To setup the stack, run the tests and then restore the pristine cluster state:

podman run -ti \
	-v $KUBECONFIG:/kubeconfig:z \
	-e KUBECONFIG=/kubeconfig \
	-e E2E_NROP_INSTALL_SKIP_KC=true \
	quay.io/openshift-kni/numaresources-operator-tests:4.18.999-snapshot \
	--setup \
	--teardown

avoiding dependencies on other images

The E2E suite depends on few extra images. These images are very stable, lightweight and little concern most of times:

  • quay.io/openshift-kni/numacell-device-plugin:test-ci
  • quay.io/openshift-kni/pause:test-ci

However, in some cases it may be unpractical to depend on third party images. The E2E test image can act as replacement for all its dependencies, providing either the same code or replacements suitables for its use case. To replace the dependencies, you need to set up some environment variables:

export E2E_IMAGE_URL=quay.io/openshift-kni/numaresources-operator-tests:4.18.999-snapshot
podman run -ti \
	-v $KUBECONFIG:/kubeconfig:z \
	-e KUBECONFIG=/kubeconfig \
	-e E2E_NROP_INSTALL_SKIP_KC=true \
	-e E2E_NUMACELL_DEVICE_PLUGIN_URL=${E2E_IMAGE_URL} \
	-e E2E_PAUSE_IMAGE_URL=${E2E_IMAGE_URL} \
	${E2E_IMAGE_URL}

running the tests using cnf-tests

The CNF tests container images includes the E2E suite. While the primary source for pre-built test container image is the numaresources-operator-tests, the CNF tests integration will be updated shortly after. Running the testsuite through CNF tests is fully supported. To run the suite using the CNF tests image, you can run

export CNF_TESTS_URL="quay.io/openshift-kni/cnf-tests:4.18.0"
podman run -ti \
	-v $KUBECONFIG:/kubeconfig:z \
	-e KUBECONFIG=/kubeconfig \
	-e CLEAN_PERFORMANCE_PROFILE=false \
	-e E2E_NROP_INSTALL_SKIP_KC=true \
	-e E2E_NUMACELL_DEVICE_PLUGIN_URL=${CNF_TESTS_URL} \
	-e E2E_PAUSE_IMAGE_URL=${CNF_TESTS_URL} \
	${CNF_TESTS_URL} \
	/usr/bin/test-run.sh \
	-ginkgo.focus="numaresources"

skipping reboot-requiring tests

Some E2E tests require to reboot one or more worker node. This is intrinsically fragile and slow, and you may want to avoid to do this in your tier-1 runs. To do so, you can run

export E2E_IMAGE_URL=quay.io/openshift-kni/numaresources-operator-tests:4.18.999-snapshot
podman run -ti \
	-v $KUBECONFIG:/kubeconfig:z \
	-e KUBECONFIG=/kubeconfig \
	-e E2E_NROP_INSTALL_SKIP_KC=true \
	-e E2E_NUMACELL_DEVICE_PLUGIN_URL=${E2E_IMAGE_URL} \
	-e E2E_PAUSE_IMAGE_URL=${E2E_IMAGE_URL} \
	${E2E_IMAGE_URL}
	--skip '.*reboot_required.*'

or, with CNF tests:

export CNF_TESTS_URL="quay.io/openshift-kni/cnf-tests:4.18.0"
podman run -ti \
	-v $KUBECONFIG:/kubeconfig:z \
	-e KUBECONFIG=/kubeconfig \
	-e CLEAN_PERFORMANCE_PROFILE=false \
	-e E2E_NROP_INSTALL_SKIP_KC=true \
	-e E2E_NUMACELL_DEVICE_PLUGIN_URL=${CNF_TESTS_URL} \
	-e E2E_PAUSE_IMAGE_URL=${CNF_TESTS_URL} \
	${CNF_TESTS_URL} \
	/usr/bin/test-run.sh \
	-ginkgo.skip='.*reboot_required.*' \
	-ginkgo.focus="numaresources"
