# 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](https://en.wikipedia.org/wiki/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](https://cloud.google.com/sdk/docs/install)
#### Configure GKE cluster access
```sh
# 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="$(kubectl config current-context)"
```
#### Install python dependencies
```sh
# Create python virtual environment
python3.6 -m venv venv
# Activate virtual environment
. ./venv/bin/activate
# Install requirements
pip install -r requirements.txt
# Generate protos
python -m grpc_tools.protoc --proto_path=../../../ \
--python_out=. --grpc_python_out=. \
src/proto/grpc/testing/empty.proto \
src/proto/grpc/testing/messages.proto \
src/proto/grpc/testing/test.proto
```
# Basic usage
### xDS Baseline Tests
Test suite meant to confirm that basic xDS features work as expected.
Executing it before other test suites will help to identify whether test failure
related to specific features under test, or caused by unrelated infrastructure
disturbances.
```sh
# Help
python -m tests.baseline_test --help
python -m tests.baseline_test --helpfull
# Run on grpc-testing cluster
python -m tests.baseline_test \
--flagfile="config/grpc-testing.cfg" \
--kube_context="${KUBE_CONTEXT}" \
--server_image="gcr.io/grpc-testing/xds-k8s-test-server-java:latest" \
--client_image="gcr.io/grpc-testing/xds-k8s-test-client-java:latest" \
```
### xDS Security Tests
```sh
# Help
python -m tests.security_test --help
python -m tests.security_test --helpfull
# Run on grpc-testing cluster
python -m tests.security_test \
--flagfile="config/grpc-testing.cfg" \
--kube_context="${KUBE_CONTEXT}" \
--server_image="gcr.io/grpc-testing/xds-k8s-test-server-java:latest" \
--client_image="gcr.io/grpc-testing/xds-k8s-test-client-java:latest" \
```
