||
| ## Summary | ||
|
|
||
| This is a KEP outlining the motivation behind why cloud providers should frequently upload E2E conformance test results to [Testgrid](https://github.com/kubernetes/test-infra/tree/master/testgrid) and how a cloud provider can go about doing this. | ||
|
|
||
| ## Motivation | ||
|
|
||
| The primary motivation behind collecting conformance test results from various cloud providers on a regular basis is to inform sig-release of any critical bugs. It's important to collect results from various cloud providers to increase coverage and inform other cloud providers of bugs they may be impacted by. | ||
|
|
||
| ### Goals | ||
|
|
||
| * All SIGs / Subprojects owners representing a cloud provider is aware of the importance of frequently uploading conformance test results to testgrid | ||
| * There is a clear and detailed process in place for any cloud provider to upload conformance test results to Testgrid. | ||
|
|
||
| ### Non-Goals | ||
|
|
||
| * Test coverage - increasing test coverage is outside the scope of this KEP | ||
| * CI/CD - what CI/CD tool is used to run E2E tests and upload results is outside the scope of this KEP. It is up to the cloud provider to decide where/how tests are run. | ||
| * Cluster Provisioning - how a cluster is provisioned is outside the scope of this KEP. | ||
|
|
||
| ## Proposal | ||
|
|
||
| We would like to propose that every Kubernetes cloud provider reports conformance test results for every patch version of Kubernetes at the minimum. Running conformance tests against master and on pre-release versions are highly encouraged but will not be a requirement. | ||
|
|
||
| ### Implementation Details/Notes/Constraints | ||
|
|
||
| Before continuing, it is highly recommended you read the following documentation provided by sig-testing: | ||
| * [Testgrid Configuration](https://github.com/kubernetes/test-infra/tree/master/testgrid#testgrid) | ||
| * [Display Conformance Tests with Testgrid](https://github.com/kubernetes/test-infra/blob/master/testgrid/conformance/README.md) | ||
|
|
||
| #### How to Run E2E Conformance Tests | ||
|
|
||
| [Sonobuoy](https://github.com/heptio/sonobuoy) is the recommended tool to run conformance tests on your cluster. At this point we will assume that you have a running cluster and that `kubectl` is configured to point to that cluster with admin access. | ||
|
|
||
| #### Installing Sonobuoy | ||
|
|
||
| The following is mostly a [copy of the sonobuoy documentation](https://github.com/heptio/sonobuoy#download-and-run). | ||
|
|
||
| First install sonobuoy. The following command adds it to the `$GOBIN` environment variable which is expected to be part of your `$PATH` environment variable. | ||
| ``` | ||
| $ go get -u github.com/heptio/sonobuoy | ||
| ``` | ||
|
|
||
| #### Running Conformance Tests with Sonobuoy | ||
|
|
||
| You can then start e2e tests by simply running: | ||
| ``` | ||
| $ sonobuoy run | ||
| Running plugins: e2e, systemd-logs | ||
| INFO[0001] created object name=heptio-sonobuoy namespace= resource=namespaces | ||
| INFO[0001] created object name=sonobuoy-serviceaccount namespace=heptio-sonobuoy resource=serviceaccounts | ||
| INFO[0001] created object name=sonobuoy-serviceaccount-heptio-sonobuoy namespace= resource=clusterrolebindings | ||
| INFO[0001] created object name=sonobuoy-serviceaccount namespace= resource=clusterroles | ||
| INFO[0001] created object name=sonobuoy-config-cm namespace=heptio-sonobuoy resource=configmaps | ||
| INFO[0002] created object name=sonobuoy-plugins-cm namespace=heptio-sonobuoy resource=configmaps | ||
| INFO[0002] created object name=sonobuoy namespace=heptio-sonobuoy resource=pods | ||
| INFO[0002] created object name=sonobuoy-master namespace=heptio-sonobuoy resource=services | ||
| ``` | ||
|
|
||
| You can then check the status of your e2e tests by running | ||
| ``` | ||
| $ sonobuoy status | ||
| PLUGIN STATUS COUNT | ||
| e2e running 1 | ||
| systemd_logs running 3 | ||
| Sonobuoy is still running. Runs can take up to 60 minutes. | ||
| ``` | ||
|
|
||
| E2E tests can take up to an hour. Once your tests are done, you can download a snapshot of your results like so: | ||
| ``` | ||
| $ sonobuoy retrieve . | ||
| ``` | ||
|
|
||
| Once you have the following snapshot, extract it's contents like so | ||
| ``` | ||
| $ mkdir ./results; tar xzf *.tar.gz -C ./results | ||
| ``` | ||
|
|
||
| At this point you should have the log file and JUnit results from your tests: | ||
| ``` | ||
| results/plugins/e2e/results/e2e.log | ||
| results/plugins/e2e/results/junit_01.xml | ||
| ``` | ||
|
|
||
| #### How to Upload Conformance Test Results to Testgrid | ||
|
|
||
| ##### Requesting a GCS Bucket | ||
|
|
||
| Testgrid requires that you store results in a publicly readable GCS bucket. If for whatever reason you cannot set up a GCS bucket, please contact @BenTheElder or more generally the [gke-kubernetes-engprod](mailto:[email protected]) team to arrange for a Google [GKE](https://cloud.google.com/kubernetes-engine/) EngProd provided / maintained bucket for hosting your results. | ||
|
|
||
| ##### Authenticating to your Testgrid Bucket | ||
|
|
||
| Assuming that you have a publicly readable bucket provided by the GKE team, you should have been provided a service account JSON file which you can use with [gcloud](https://cloud.google.com/sdk/downloads) to authenticate with your GCS bucket. | ||
|
|
||
| ``` | ||
| $ gcloud auth activate-service-account --key-file /path/to/k8s-conformance-serivce-accout.json | ||
| Activated service account credentials for: [demo-bucket-upload@k8s-federated-conformance.iam.gserviceaccount.com] | ||
| ``` | ||
|
|
||
| ##### Uploading results to Testgrid | ||
|
|
||
| At this point you should be able to upload your testgrid results to your GCS bucket. You can do so by running a python script availabile [here](https://github.com/kubernetes/test-infra/tree/master/testgrid/conformance). For this example, we upload results for v1.10 into it's own GCS prefix. | ||
| ``` | ||
| git clone https://github.com/kubernetes/test-infra | ||
| cd testgrid/conformance | ||
| ./upload_e2e.py --junit /path/to/results/plugins/e2e/results/e2e.log \ | ||
| --log /path/to/results/plugins/e2e/results/e2e.log \ | ||
| --bucket=gs://k8s-conformance-demo/cloud-provider-demo/e2e-conformance-release-v1.10 | ||
| Uploading entry to: gs://k8s-conformance-demo/cloud-provider-demo/e2e-conformance-release-v1.10/1528333637 | ||
| Run: ['gsutil', '-q', '-h', 'Content-Type:text/plain', 'cp', '-', 'gs://k8s-conformance-demo/cloud-provider-demo/e2e-conformance-release-v1.10/1528333637/started.json'] stdin={"timestamp": 1528333637} | ||
| Run: ['gsutil', '-q', '-h', 'Content-Type:text/plain', 'cp', '-', 'gs://k8s-conformance-demo/cloud-provider-demo/e2e-conformance-release-v1.10/1528333637/finished.json'] stdin={"timestamp": 1528337316, "result": "SUCCESS"} | ||
| Run: ['gsutil', '-q', '-h', 'Content-Type:text/plain', 'cp', '/Users/AndrewSyKim/go/src/k8s.io/kubernetes/results/plugins/e2e/results/e2e.log', 'gs://k8s-conformance-demo/cloud-provider-demo/e2e-conformance-release-v1.10/1528333637/build-log.txt'] | ||
| Run: ['gsutil', '-q', '-h', 'Content-Type:text/plain', 'cp', '/Users/AndrewSyKim/go/src/k8s.io/kubernetes/results/plugins/e2e/results/e2e.log', 'gs://k8s-conformance-demo/cloud-provider-demo/e2e-conformance-release-v1.10/1528333637/artifacts/e2e.log'] | ||
| Done. | ||
| ``` | ||
|
|
||
| ##### Testgrid Configuration | ||
|
|
||
| Next thing you want to do is configure testgrid to read results from your GCS bucket. There are two [configuration](https://github.com/kubernetes/test-infra/tree/master/testgrid#configuration) steps required. One for your [test group](https://github.com/kubernetes/test-infra/tree/master/testgrid#test-groups) and one for your [dashboard](https://github.com/kubernetes/test-infra/tree/master/testgrid#dashboards). | ||
|
|
||
| To add a test group update [config.yaml](https://github.com/kubernetes/test-infra/blob/master/testgrid/config.yaml) with something like the following: | ||
| ``` | ||
| test_groups: | ||
| ... | ||
| ... | ||
| - name: cloud-provider-demo-e2e-conformance-release-v1.10 | ||
| gcs_prefix: k8s-conformance-demo/cloud-provider-demo/e2e-conformance-release-v1.10 | ||
| ``` | ||
|
|
||
| To add a link to your results in the testgrid dashboard, update [config.yaml](https://github.com/kubernetes/test-infra/blob/master/testgrid/config.yaml) with something like the following: | ||
| ``` | ||
| dashboards: | ||
| ... | ||
| ... | ||
| - name: conformance-demo-cloud-provider | ||
| dashboard_tab: | ||
| - name: "Demo Cloud Provider, v1.10" | ||
| description: "Runs conformance tests for cloud provier demo on release v1.10" | ||
| test_group_name: cloud-provider-demo-e2e-conformance-release-v1.10 | ||
| ``` | ||
|
|
||
| Once you've made the following changes, open a PR against the test-infra repo. Once your PR merges you should be able to view your results on https://k8s-testgrid.appspot.com/ which should be ready to be consumed by the necessary stakeholders (sig-release, sig-testing, etc). | ||
|
|
||
|
|
||
| #### Examples | ||
|
|
||
| Here are some more concrete examples of how other cloud providers are running conformance tests and uploading results to testgrid: | ||
| * Open Stack | ||
| * [OpenLab zuul job for running/uploading testgrid results](https://github.com/theopenlab/openlab-zuul-jobs/tree/master/playbooks/cloud-provider-openstack-acceptance-test-e2e-conformance) | ||
| * [OpenStack testgrid config](https://github.com/kubernetes/test-infra/pull/7670) | ||
| * [OpenStack conformance tests dashboard](https://github.com/kubernetes/test-infra/pull/8154) | ||
|

|
||
| ### Risks and Mitigations | ||
|
|
||
| #### Operational Overhead | ||
|
|
||
| Operating CI/CD system to run conformance tests on a regular basis may incur extra work from every cloud provider. Though we anticipate the benefits of running conformance tests to outweight the operational overhead, in some cases it may not. | ||
|
|
||
| Mitigation: TODO | ||
|
|
||
| #### Misconfigured Tests | ||
|
|
||
| There are various scenarios where cloud providers may mistakenly upload incorrect conformance tests results. One example being uploading results for the wrong Kubernetes version. | ||
|
|
||
| Mitigation: TODO | ||
|
|
||
| #### Flaky Tests | ||
|
|
||
| Tests can fail for various reasons in any cloud environment and may raise false negatives for the release team. | ||
|
|
||
| Mitigation: TODO | ||
|
|
||
|
|
||
| ## Graduation Criteria | ||
|
|
||
| All providers are uploading conformance test results as part of every Kubernetes major/minor/patch release. | ||
|
|
||
| [umbrella issues]: TODO | ||
|
