test-network-policies

This repo contains a set of tests for Kubernetes network policies.
test-netpol.sh sets up a 'hello' pod and service in namespace default and a second namespace 'second'.
Then, each test script under tests applies some network policy and runs a client pod to test that connectivity succeeds or fails according to expected behavior.

Setting up a cluster

Before running the tests, setup a cluster with network policies enabled.
Note that GKE disables network policies by default.

Connecting to the cluster

Make sure you are connected to your cluster as cluster admin.
kubectl should be able to create pods, services and network policies.

Running the tests

Run all tests (with proxy):

# CURL_PROXY="-x 10.0.1.10:3128"
./test-netpol.sh

You should see "SUCCESS" after each test. If you see "FAIL" then something went wrong.
If you think its a bug, please submit an issue with the kubernetes and CNI platform/version details, and the failing test.

Run a single test:

# pass relative path to test file as argument
./test-netpol.sh tests/alllow-all-without-internet.sh

Tufin SecureCloud

I wrote these tests while developing SecureCloud which is a Kubernetes security solution.
I welcome you to try SecureCloud on your own cluster and share your feedback:
