xDS Kubernetes Interop Tests

Proxyless Security Mesh Interop Tests executed on Kubernetes.

Experimental

Work in progress. Internal APIs may and will change. Please refrain from making changes to this codebase at the moment.

Stabilization roadmap

  • Replace retrying with tenacity
  • Generate namespace for each test to prevent resource name conflicts and allow running tests in parallel
  • Security: run server and client in separate namespaces
  • Make framework.infrastructure.gcp resources first-class citizen, support simpler CRUD
  • Security: manage roles/iam.workloadIdentityUser role grant lifecycle for dynamically-named namespaces
  • Restructure framework.test_app and framework.xds_k8s* into a module containing xDS-interop-specific logic
  • Address inline TODOs in code
  • Improve README.md documentation, explain helpers in bin/ folder

Installation

Requirements

  1. Python v3.6+
  2. Google Cloud SDK

Configure GKE cluster access

# Update gloud sdk
gcloud -q components update

# Configuring GKE cluster access for kubectl
gcloud container clusters get-credentials "your_gke_cluster_name" --zone "your_gke_cluster_zone"

# Save generated kube context name
KUBE_CONTEXT="$(kubectl config current-context)"

Install python dependencies

# Create python virtual environment
python3.6 -m venv venv

# Activate virtual environment
. ./venv/bin/activate

# Install requirements
pip install -r requirements.txt

# Generate protos
python -m grpc_tools.protoc --proto_path=../../../ \
    --python_out=. --grpc_python_out=. \
    src/proto/grpc/testing/empty.proto \
    src/proto/grpc/testing/messages.proto \

Basic usage

xDS Baseline Tests

Test suite meant to confirm that basic xDS features work as expected. Executing it before other test suites will help to identify whether test failure related to specific features under test, or caused by unrelated infrastructure disturbances.
