.. _fuel_ccp_test_plan: ==================================================== Fuel Containerized Control Plane performance testing ==================================================== :status: **ready** :version: 1.0 :Abstract: This test plan aims to provide set of tests to identify OpenStack performance against given containerized OpenStack cloud (installed on the top of pre-deployed Kubernetes cluster) using simple minimalistic set of Rally tests. Test Plan ========= This document is inspired by :ref:`openstack_control_plane_performance_test_plan`, and aims to cover baseline cloud operations and extend this test suite to verify containerized deployment approach. As :ref:`openstack_control_plane_performance_test_plan` this test plan covers basic cloud operations e.g. VMs creation, work with the security groups, authentication and more, as well as long-running test suites to verify cloud stability. Test Environment ---------------- Preparation ^^^^^^^^^^^ This test plan is performed against existing OpenStack cloud installed on top of pre-deployed Kubernetes cluster with `fuel-ccp`_ tool with pre-installed Rally framework. .. _fuel-ccp: http://fuel-ccp.readthedocs.io/en/latest/ Environment description ^^^^^^^^^^^^^^^^^^^^^^^ The environment description includes hardware specification of servers, network parameters, operation system and OpenStack deployment characteristics.

To make this possible, **Rally** automates and unifies multi-node OpenStack deployment, cloud verification, benchmarking & profiling. This is a simple way to check cloud workability and performance of control plane operations running on it. Test Case 1: Boot and delete server ----------------------------------- Description ^^^^^^^^^^^ The most user-facing control plane operation is new virtual machine creation. This scenario covers the most basic OpenStack server creation to present the baseline numbers for Nova (OpenStack Compute) control plane. Parameters ^^^^^^^^^^ +-------------------------+-----------------------------------------+ |Name | Description | +=========================+=========================================+ |IMAGE | Image from which boot server | +-------------------------+-----------------------------------------+ |FLAVOR | Flavor type from which boot server | +-------------------------+-----------------------------------------+ |ASSIGN_NIC | Bool, whether or not to auto assign | | | NICs in Rally scenario | +-------------------------+-----------------------------------------+ |CONCURRENCY | Amount of parallel executors | +-------------------------+-----------------------------------------+ |ITERATIONS | Total amount of iterations processed by | | | all executors | +-------------------------+-----------------------------------------+ List of performance metrics ^^^^^^^^^^^^^^^^^^^^^^^^^^^ +----------+-------+-------------------+---------------------------+ | Priority | Value | Measurement Units | Description | +==========+=======+===================+===========================+ | 1 | | sec | Time of atomic operations | +----------+-------+-------------------+---------------------------+ Measuring performance values ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 1. Create server with FLAVOR flavor from IMAGE image through Nova API 2. Delete server through Nova API. These 2 steps executed successively in CONCURRENCY parallel executors. ASSIGN_NIC parameter reflects Rally scenario configuration whether to assign NIC to the booted server in automatic fashion. One cycle of these 2 steps is called an iteration. ITERATIONS is a total amount of iterations which was processed by executors. At the end of this test case you should calculate average, 90% percentile, 50% percentile, minimum and maximum for each step. You need to fill the following tables with calculated values: Nova ---- +---------------+------+--------+--------+-------+-------+ | Operation | Mean | 90%ile | 50%ile | Max | Min | | | (sec)| (sec) | (sec) | (sec) | (sec) | +===============+======+========+========+=======+=======+ | create_server | | | | | | +---------------+------+--------+--------+-------+-------+ | delete_server | | | | | | +---------------+------+--------+--------+-------+-------+ Example of Rally scenario configuration ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ .. literalinclude:: test_plans/021-nova-boot-and-delete-baseline.yaml :language: bash Test Case 2: Boot and delete server with security groups -------------------------------------------------------- Description ^^^^^^^^^^^ The most user-facing control plane operation is new virtual machine creation. At the same time security groups management is very time consuming operation in case of lots VMs attached to the same security group, therefore it's vital to understand these operations performance. Standard Rally scanario is used for this purpose (comparing with :ref:`openstack_control_plane_performance_test_plan` fuel-ccp does not support yet Cinder installation or appropriate Nova configuration to support live migrations, so there is no need to write separated plugin to cover these operations).
