From 120daffd8d6d4be727d2ba52a76dbd8eacfe2628 Mon Sep 17 00:00:00 2001 From: Cédric Ollivier Date: Wed, 2 Sep 2020 19:46:25 +0200 Subject: Add cnf-conformance in functest-kubernetes-cnf MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit It selects cnf-conformance v0.7.2-beta1 (current latest release) and the default CNF as proposed by [1]. The end user is free to override the default yml files on purpose (e.g. docker volumes). Tag (default: all) could be modified too via testcases.yaml [1] https://hackmd.io/@vulk/SkY54QnsU Change-Id: Iec2a830c441e523e067f6eb114ecb205c49c6b93 Signed-off-by: Cédric Ollivier --- ansible/site.yml | 1 + docker/cnf/Dockerfile | 15 +++ docker/cnf/testcases.yaml | 13 +++ functest_kubernetes/cnf_conformance/__init__.py | 0 functest_kubernetes/cnf_conformance/conformance.py | 104 +++++++++++++++++++++ setup.cfg | 1 + 6 files changed, 134 insertions(+) create mode 100644 functest_kubernetes/cnf_conformance/__init__.py create mode 100644 functest_kubernetes/cnf_conformance/conformance.py diff --git a/ansible/site.yml b/ansible/site.yml index 939ab915..dc6f4d19 100644 --- a/ansible/site.yml +++ b/ansible/site.yml @@ -55,4 +55,5 @@ - xrally_kubernetes_full - container: functest-kubernetes-cnf tests: + - cnf_conformance - k8s_vims diff --git a/docker/cnf/Dockerfile b/docker/cnf/Dockerfile index bc8a6fe7..2a1dac24 100644 --- a/docker/cnf/Dockerfile +++ b/docker/cnf/Dockerfile @@ -1,4 +1,19 @@ FROM opnfv/functest-kubernetes-core +ARG CNF_CONFORMANCE_TAG=v0.7.2-beta1 + +RUN apk --no-cache add --update wget curl libc6-compat && \ + K8S_TAG=$(curl -s https://storage.googleapis.com/kubernetes-release/release/latest-1.19.txt) && \ + case $(uname -m) in armv7l) ARCH=arm;; aarch64) ARCH=arm64;; x86_64) ARCH=amd64;; esac && \ + curl https://storage.googleapis.com/kubernetes-release/release/$K8S_TAG/bin/linux/$ARCH/kubectl \ + -s --output /usr/local/bin/kubectl && \ + curl https://github.com/cncf/cnf-conformance/releases/download/$CNF_CONFORMANCE_TAG/cnf-conformance-$(echo $CNF_CONFORMANCE_TAG |cut -d\- -f 1)-$ARCH-static \ + -Ls --output /usr/local/bin/cnf-conformance && \ + chmod +x /usr/local/bin/kubectl /usr/local/bin/cnf-conformance && \ + mkdir -p /src/cnf-conformance && \ + curl -Ls https://raw.githubusercontent.com/cncf/cnf-conformance/$CNF_CONFORMANCE_TAG/example-cnfs/coredns/cnf-conformance.yml \ + -s --output /src/cnf-conformance/cnf-conformance.yml && \ + curl -Ls https://raw.githubusercontent.com/cncf/cnf-conformance/$CNF_CONFORMANCE_TAG/points.yml \ + -s --output /src/cnf-conformance/points.yml COPY testcases.yaml /usr/lib/python3.8/site-packages/xtesting/ci/testcases.yaml CMD ["run_tests", "-t", "all"] diff --git a/docker/cnf/testcases.yaml b/docker/cnf/testcases.yaml index 68d1788d..e0d8bcb2 100644 --- a/docker/cnf/testcases.yaml +++ b/docker/cnf/testcases.yaml @@ -6,6 +6,19 @@ tiers: description: >- Collection of VNF test cases. testcases: + - + case_name: cnf_conformance + project_name: functest + criteria: 90 + blocking: false + description: >- + Enable interoperability of Cloud native Network + Functions (CNFs) as proposed by + https://github.com/cncf/cnf-conformance + dependencies: + - DEPLOY_SCENARIO: 'k8-*' + run: + name: cnf_conformance - case_name: k8s_vims project_name: functest diff --git a/functest_kubernetes/cnf_conformance/__init__.py b/functest_kubernetes/cnf_conformance/__init__.py new file mode 100644 index 00000000..e69de29b diff --git a/functest_kubernetes/cnf_conformance/conformance.py b/functest_kubernetes/cnf_conformance/conformance.py new file mode 100644 index 00000000..1f80f15c --- /dev/null +++ b/functest_kubernetes/cnf_conformance/conformance.py @@ -0,0 +1,104 @@ +#!/usr/bin/env python + +# Copyright (c) 2020 Orange and others. +# +# All rights reserved.
