## DNSPolicy Scale Testing
2+
3+
Create two kind clusters with Kuadrant installed:
4+
```bash
5+
CLUSTER_COUNT=2 ./hack/dnspolicy-scale-testing/test.sh kind-create
6+
```
7+
8+
Installed namespaced dns operators (optional):
9+
```bash
10+
CLUSTER_COUNT=2 ./hack/dnspolicy-scale-testing/test.sh kind-install-namespaced-dns-operator
11+
```
12+
13+
Run a test:
14+
```bash
15+
CLUSTER_COUNT=2 TEST_NS_COUNT=5 ./hack/dnspolicy-scale-testing/test.sh test_dnspolicy_loadbalanced aws
16+
```
17+
18+
Cleanup after test:
19+
20+
Delete all dnspolices created by tests first and ensure all dnsrecords are removed
21+
```shell
22+
kubectl get dnspolicy -l kuadrant.io/test-suite=manual -A --context kind-kuadrant-local-1
23+
kubectl delete dnspolicy -l kuadrant.io/test-suite=manual -A --context kind-kuadrant-local-1
24+
kubectl get dnsrecord -A --context kind-kuadrant-local-1
25+
```
26+
27+
Delete all other test suite resources
28+
```shell
29+
kubectl get all,httproutes,gateway,tlspolicy,secrets,issuers -l kuadrant.io/test-suite=manual -A --context kind-kuadrant-local-1
30+
kubectl delete all,httproutes,gateway,tlspolicy,secrets,issuers -l kuadrant.io/test-suite=manual -A --context kind-kuadrant-local-1
31+
```
