-K8s Container Memif
--------------------
-
-CSIT includes tests of VPP topologies running in K8s
-orchestrated Pods/Containers and connected over memif virtual
-interfaces. In order to provide simple topology coding flexibility and
-extensibility container orchestration is done with `Kubernetes
-<https://github.com/kubernetes>`_ using `Docker
-<https://github.com/docker>`_ images for all container applications
-including VPP. `Ligato <https://github.com/ligato>`_ is used for the
-Pod/Container networking orchestration that is integrated with K8s,
-including memif support.
-
-In these tests VPP vswitch runs in a K8s Pod with Docker Container (DRC)
-handling NIC interfaces and connecting over memif to more instances of
-VPP running in Pods/DRCs. All DRCs run in a priviliged mode with VPP
-data plane worker threads pinned to dedicated physical CPU cores per
-usual CSIT practice. All VPP instances run the same version of software.
-This test topology is equivalent to existing tests with vhost-user and
-VMs as described earlier in :ref:`tested_physical_topologies`.
-
-Further documentation is available in
-:ref:`container_orchestration_in_csit`.

+requires complicated algorithms.
Two types of YAML templates are defined:
- Static - do not change between deployments, that is infrastructure
containers like Kafka, Calico, ETCD.
-- Dynamic - per test suite/case topology YAML files e.g. SFC_controller,
- VNF, VSWITCH.
+- Dynamic - per test suite/case topology YAML files.
Making own python wrapper library of ``kubectl`` instead of using the
official Python package allows to control and deploy environment over
the SSH library without the need of using isolated driver running on
each of DUTs.
-Ligato
-~~~~~~
-
-Ligato integration does require to compile the ``vpp-agent`` tool and build the
-bundled Docker image. Compilation of ``vpp-agent`` depends on specific VPP. In
-``ligato/vpp-agent`` repository there are well prepared scripts for building the
-Docker image. Building docker image is possible via series of commands:
-
-::
-
- git clone https://github.com/ligato/vpp-agent
- cd vpp_agent/docker/dev_vpp_agent
- sudo docker build -t dev_vpp_agent --build-arg AGENT_COMMIT=<agent commit id>\
- --build-arg VPP_COMMIT=<vpp commit id> --no-cache .
- sudo ./shrink.sh
- cd ../prod_vpp_agent
- sudo ./build.sh
- sudo ./shrink.sh
-
-CSIT requires Docker image to include the desired VPP version (per patch
-testing, nightly testing, on demand testing).
-
-The entire build process of building ``dev_vpp_agent`` image heavily depends
-on internet connectivity and also takes a significant amount of time (~1-1.5h
-based on internet bandwidth and allocated resources). The optimal solution would
-be to build the image on jenkins slave, transfer the Docker image to DUTs and
-execute separate suite of tests.
-
-To adress the amount of time required to build ``dev_vpp_agent`` image, we can
-pull existing specific version of ```dev_vpp_agent``` and exctract the
-```vpp-agent``` from it.
-
-We created separate sets of Jenkins jobs, that will be executing following:
-
-1. Clone latest CSIT and Ligato repositaries.
-2. Pull specific version of ``dev_vpp_agent`` image from Dockerhub.
-3. Extract VPP API (from ``.deb`` package) and copy into ``dev_vpp_agent``
- image
-4. Rebuild vpp-agent and extract outside image.
-5. Build ``prod_vpp_image`` Docker image from ``dev_vpp_agent`` image.
-6. Transfer ``prod_vpp_agent`` image to DUTs.
-7. Execute subset of performance tests designed for Ligato testing.

-In CSIT we need to create separate performance suite under
-``tests/kubernetes/perf`` which contains modified Suite setup in comparison
-to standard perf tests. This is due to reason that VPP will act as vswitch in
-Docker image and not as standalone installed service.
