OCRE Test-Suite for cloud validation - CERN¶
This tool is intended to be used to test and validate commercial cloud services across the stack for research and education environments. This Test-Suite is being used as a validation tool for commercial cloud services procurement in OCRE (Open Clouds for Research Environments) project sponsored by the European Commission.

The test-suite executes four main steps:
- Infrastructure provisioning: VMs are created using Terraform and then Kubernetes and Docker are installed on them to create several k8s cluster according to the selected tests.
- Deploy the tests: Kubernetes resource definition files (YAML) are used to deploy the tests, either as single pods or deployments.
- Harvest results: at the end of each test run a result file -written in JSON- is created. This file is harvested from the cluster and stored locally.
- Through a verification system, the Test-Suite can also be triggered from a service running at CERN. In this case, results are then pushed to a S3 Bucket at CERN. (Under development)
The test set described below is based on the tests used in Helix Nebula The Science Cloud PCP project funded by the European Commission.
The developers would like to thank to all test owners and contributors to this project.
This test-suite has been tested on:
|Linux distros||Ubuntu, CentOS, CoreOS, Debian, RedHat, Fedora|
|OS running on provider’s VMs||CentOS7|
CERN Private Cloud (OpenStack)
The test suite is being tested in several additional cloud providers. As tests are concluded the cloud providers names will be added in the table above.
(Note the versions are numbered with the date of the release: YEAR.MONTH)
-Parallel creation of clusters, with different flavors according to tests needs.
-New logging system to keep parallel running tests logs sorted.
-Restructured configuration: moved configuration files to /configurations and created new files taking HCL code (terraform configuration code) to keep configs.yaml clean.
-Automated allowance of root ssh by copying open user’s authorized_keys to root’s ~/.ssh as well as sshd_config modification.
-Usage of Kubernetes API instead of Kubernetes CLI.
-For network test (perfSONAR), usage of API instead of pscheduler CLI.
-New test: Dynamic On Demand Analysis Service, provided by INFN.
-Added configurations validation with jsonschema.
-Created Docker image to run a Test-Suite launcher container: rapidly creates a ready to use Test-Suite launcher.
-New tests: perfsonar and cpu-benchmarking
