Integration Continuous Integration Guide ---------------------------------------- Continuous Integration is key due to the complexity of the ONAP projects. Several chains have been created: - Daily stable chain - Daily master chain - Gating: On demand deployment of a full ONAP solution to validate patchsets They are run on different environments (Orange labs, DT labs, Azure Cloud). The following document will detail these chains and how you could set up such chains and/or provide test results to the community. Integration CI Ecosystem ------------------------ Overview ~~~~~~~~ The global ecosystem can de described as follows: .. figure:: files/CI/ONAP_CI_10.png :align: center Several chains are run in ONAP. The CI chains are triggered from different CI systems (Jenkins or gitlab-ci) (1) on different target environments hosted on community labs (Windriver, Orange, DT, E///) or Azure clouds. Jobs (installation, tests) are executed on these labs (2). At the end, the results are pushed through the OPNFV test API (3) to a test database (4) hosted by Linux Foundation on http://testresults.opnfv.org. Results can be reported in different web pages hosted on LF or on gitlab.com (5). Daily Chains ~~~~~~~~~~~~ CI daily chains (Master and last Stable) are run on Orange, DT using gitlab-ci jobs and Ericsson using jenkins jobs. Gating ~~~~~~ OOM gating has been introduced for El Alto. It consists of a deployment followed by a set of tests on patchsets submitted to OOM repository. The CI part is managed on gitlab.com and the deployment is executed on ONAP Orange lab and Azure clouds. The goal is to provide a feedback - and ultimately to vote - on code change prior to merge to consolidate the OOM Master branch. The developer can evaluate the consequences of his/her patchset on a fresh installation. The gating is triggered in 2 scenarios: - new patchset in OOM - comment with the magic word **oom_redeploy** is posted in the Gerrit's comment section The procedure to submit new feature in CI is done in 3 steps as described in the figure below: .. figure:: files/CI/ONAP_CI_0.png :align: center Visualization of the CI pipelines ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ As the CI chains are triggered from different systems, several web interfaces can be used to visualize them. A web site has been created to centralize the links on http://testresults.opnfv.org/onap-integration/index.html .. figure:: files/CI/ONAP_CI_3.png :align: center For Gating and gitlab.com based CI chains, the pipelines consist in pipelines of pipelines managed through the chaining of .gitlab-ci.yml file thanks to an Open Source deployment called chained-ci (https://gitlab.com/Orange-OpenSource/lfn/ci_cd/chained-ci). A visualization tool is available to list all your chains as described in the figure below: .. figure:: files/CI/ONAP_CI_1.png :align: center If you click on any element of the chain, you will open a new window: .. figure:: files/CI/ONAP_CI_2.png :align: center In order to provide the logs to the developer an additional web page has been created to summarize the tests and grant access to their associated logs: .. figure:: files/CI/ONAP_CI_8.png :align: center Additionnaly, for the daily chain, another page displays the results as time series, allowing to see the evolution of the tests over time. .. figure:: files/CI/ONAP_CI_9.png :align: center Setup Your Own CI Chains ------------------------ If you want to setup a gitlab.com based CI chain, and want to use chained-ci, you can follow the tutorial on https://gitlab.com/Orange-OpenSource/lfn/ci_cd/chained-ci-handson You should be able to chain your automation projects: * Create resources * Deployment of Kubernetes * Test of your Kubernetes (using OPNFV functest-k8s tests) * Deployment of your ONAP (you can use your own automatic installation procedure or https://gitlab.com/Orange-OpenSource/lfn/onap/onap_oom_automatic_installation/) * Test ONAP thanks to the differnet ONAP xtesting dockers covering infrastructure healthcheck, components healthcheck tests, end to end tests, security tests. If you want to report your results to the community, do not hesitate to contact the integration team. The Test database is public but the pods must be declared to be allowed to report results from third party labs. ONAP Integration Testing Gate ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 5 categories have been defined for the ONAP integration testing gate: * infrastructure healthcheck: verify ONAP from a k8S perspective. It includes 2 tests: onap-k8s (all the deployments, jobs, statefulste,..must be OK at the end of an installation), onap-helm (all the helm chart must be completed at the end of the installation) * healthcheck: the traditionnal robot tests run from the cluster to perform tests on the different components. * smoke-usecases: End to end tests * candidate-usecases: New end to end tests introduced in the automation chain for the release * security tests (security of kubernetes (CVE, CIS tests) and ONAP (exposed ports, check the containers run as root,...)) * benchmarking (robustness, stress tests): not yet available All these tests have been packaged thanks to the OPNFV Open Source tool xtesting. Xtesting is a python package allowing to unify the way to declare, run tests. It also ensures a consistent way to get the test results whatever the test framework used (python, robotframework, bash, ...). It includes the mechanism to automatically push the results to the test database using the test API. It simplifies the integration in CI. The package can be found here https://pypi.org/project/xtesting/. The different ONAP xtesting dockers can be found on https://gitlab.com/Orange-OpenSource/lfn/onap/integration/xtesting/container_registry As an illustration, you can run the infrastructure healthcheck by typing the following command:: docker run -v :/root/.kube/config -v : /var/lib/xtesting/results registry.gitlab.com/orange-opensource/lfn/onap/integration/xtesting/infra-healthcheck:latest All the xtesting tests are included in Daily and gating chains. Please note that you can build your own onap-xtesting docker if you want to include your tests. See https://wiki.onap.org/pages/viewpage.action?pageId=79202765 for details.
