**Auto-Discovery** automatically finds all supported resources. The deny list is comprehensive and prevents mirroring of dangerous or inappropriate resources.
|
||||
|
||||
## Cache Staleness
|
||||
|
||||
Kubernetes controllers use informer caches for performance. KubeMirror implements a hybrid strategy to handle cache lag:
|
||||
|
||||
**The Problem:**
|
||||
1. Source Secret updated → Watch event arrives
|
||||
2. Reconciliation triggered immediately3. Controller reads from cache → **Gets stale data** (cache hasn't updated yet)
|
||||
4. Stale data mirrored to targets5. Cache updates 5-20 seconds later → But reconciliation already ran
|
||||
|
||||
**The Solution (Optional):**
|
||||
|
||||
Enable `--verify-source-freshness=true` to activate hybrid caching:
|
||||
1. Read from cache (fast)
|
||||
2. Make direct API call to verify freshness
|
||||
3. If resourceVersions differ → Use fresh API data
|
||||
4. If resourceVersions match → Use cached data
|
||||
|
||||
**Trade-offs:**
|
||||
|
||||
| Mode | API Calls | Data Freshness | Use Case |
|
||||
|------|-----------|----------------|----------|
|
||||
| **Default** (`false`) | 0 extra calls | Eventually consistent (5-20s lag) | Most deployments - 95%+ of updates propagate correctly |
|
||||
| **Freshness Verification** (`true`) | 1-2 extra calls per update | Always fresh | Critical secrets that must propagate immediately |
|
||||
|
||||
**Recommendation:** Default mode is sufficient for most use cases. Enable freshness verification only for environments where stale data is unacceptable (e.g., security-critical secrets, zero-downtime deployments).

# KubeMirror E2E Tests
|
||||
|
||||
Comprehensive, DRY (Don't Repeat Yourself) test framework for KubeMirror functionality.
|
||||
|
||||
## Overview
|
||||
|
||||
The test suite uses a **data-driven framework** approach where test scenarios are systematically defined and executed using reusable functions. This ensures comprehensive coverage of all edge cases without code duplication.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Kubernetes cluster running (tested with docker-desktop)
|
||||
- kubectl configured and pointing to docker-desktop context
|
||||
- Go 1.21+ installed
|
||||
- curl (for health checks)
|
||||
|
||||
## Test Architecture
|
||||
|
||||
### Test Framework Components
|
||||
|
||||
1. **common.sh**: Base utilities (logging, assertions, cleanup)
|
||||
2. **test-framework.sh**: DRY test framework functions (resource creation, updates, verification)
|
||||
3. **test-comprehensive.sh**: Comprehensive test scenarios using the framework
|
||||
4. **run-all-tests.sh**: Main test runner (builds binary, starts controller, runs tests)
|
||||
|
||||
### Test Framework Functions
|
||||
|
||||
The framework provides reusable functions for all operations:
|
||||
|
||||
```bash
|
||||
# Resource lifecycle
|
||||
create_source <type> <name> <namespace> <has_label> <has_annotation> <targets> <data>
|
||||
update_source_labels <type> <name> <namespace> <enabled_value>
|
||||
update_source_annotations <type> <name> <namespace> <sync_value> <targets>
|
||||
update_source_data <type> <name> <namespace> <new_data>
|
||||
|
||||
# Namespace operations
|
||||
create_test_namespace <name> <allow_mirrors_label>
|
||||
update_namespace_labels <namespace> <allow_mirrors_value>
|
||||
delete_namespace <namespace>
|
||||
|
||||
# Verification functions
|
||||
verify_mirrors_exist <type> <name> <namespace1> <namespace2> ...
|
||||
verify_mirrors_not_exist <type> <name> <namespace1> <namespace2> ...
|
||||
verify_mirror_data <type> <source_name> <source_ns> <target_ns> <expected_data>
|
||||
verify_orphan_cleanup <type> <name> <namespace1> <namespace2> ...
|
||||
```
|
||||
|
||||
## Comprehensive Test Suite
|
||||
|
||||
The comprehensive test suite (`test-comprehensive.sh`) covers **22 systematic scenarios**:
|
||||
|
||||
### Source Lifecycle Scenarios
|
||||
|
||||
1. **Source without labels/annotations**: No mirrors created
|
||||
2. **Add enabled label**: Still no mirrors (sync annotation required)
|
||||
3. **Add sync annotation**: Mirrors created in targets
|
||||
4. **Modify source data**: Mirrors updated
|
||||
5. **Set sync to false**: All mirrors deleted
|
||||
6. **Set enabled to false**: All mirrors deleted
|
||||
|
||||
### Target Namespace Management
|
||||
|
||||
7. **Add namespace to list**: New mirror created
|
||||
8. **Remove namespace from list**: Orphaned mirror deleted
|
||||
9. **Change list to pattern**: Old mirrors deleted, new pattern mirrors created
|
||||
10. **Multiple patterns**: Mirrors in all matching namespaces
|
||||
|
||||
### Pattern Matching
|
||||
|
||||
11. **Create namespace matching pattern**: Automatic mirror creation
|
||||
12. **Mix explicit + pattern**: Both types work together
|
||||
13. **Change pattern**: Orphaned mirrors cleaned up
|
||||
|
||||
### 'all' Keyword with Opt-in
|
||||
|
||||
14. **'all' without namespace label**: No mirror created
|
||||
15. **Add allow-mirrors label**: Mirror created
|
||||
16. **Remove allow-mirrors label**: Mirror deleted
|
||||
17. **Change label true→false**: Mirror deleted
|
||||
|
||||
### Edge Cases
|
||||
|
||||
18. **Target namespace deleted**: Other mirrors unaffected
|
||||
19. **Recreate deleted namespace**: Mirror recreated
|
||||
20. **Source deleted**: Cascade deletion of all mirrors
|
||||
21. **Target manually deleted**: Automatic recreation
|
||||
22. **Remove sync annotation**: All mirrors deleted
|
||||
|
||||
### Resource Types
|
||||
|
||||
All scenarios tested with both **Secrets** and **ConfigMaps**.
|
||||
|
||||
## Running Tests
|
||||
|
||||
### Run Complete Test Suite
|
||||
|
||||
```bash
|
||||
cd e2e
|
||||
./run-all-tests.sh
|
||||
```
|
||||
|
||||
This will:
|
||||
1. Check you're on docker-desktop context
|
||||
2. Build the KubeMirror binary
|
||||
3. Start the controller in background
|
||||
4. Run comprehensive test scenarios (22+ scenarios)
|
||||
5. Report detailed results with pass/fail for each
|
||||
6. Clean up all resources automatically
|
||||
|
||||
### Run Individual Test Scenarios
|
||||
|
||||
```bash
|
||||
# Must have KubeMirror controller running first
|
||||
cd /Users/nvm/Documents/projects/private/kube-mirror
|
||||
./kubemirror --max-targets=100 --worker-threads=5 > /tmp/kubemirror-test.log 2>&1 &
|
||||
|
||||
# Then run the test
|
||||
cd e2e
|
||||
./test-comprehensive.sh
|
||||
```
|
||||
|
||||
## Test Output
|
||||
|
||||
Each test produces colored output:
|
||||
- 🔵 **[INFO]**: Informational messages
|
||||
- ✅ **[PASS]**: Test passed
|
||||
- ❌ **[FAIL]**: Test failed
|
||||
- ⚠️ **[WARN]**: Warning messages

|

```
|
||||
|
||||
## Test Resources
|
||||
|
||||
Tests create temporary resources:
|
||||
- **Namespaces**: `e2e-*` prefixed
|
||||
- **Secrets**: `test-*` prefixed in default namespace
|
||||
- **ConfigMaps**: `test-*` prefixed in default namespace
|
||||
|
||||
All resources are cleaned up automatically on test completion.
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Tests fail with "context not docker-desktop"
|
||||
|
||||
Switch to docker-desktop context:
|
||||
```bash
|
||||
kubectl config use-context docker-desktop
|
||||
```
|
||||
|
||||
### Tests timeout waiting for resources
|
||||
|
||||
Controller may not be running or not reconciling. Check:
|
||||
```bash
|
||||
# Check if controller is running
|
||||
ps aux | grep kubemirror
|
||||
|
||||
# Check controller logs
|
||||
tail -f /tmp/kubemirror-e2e-test.log
|
||||
|
||||
# Check controller health
|
||||
curl http://localhost:8081/healthz
|
||||
```
|
||||
|
||||
### Cleanup hanging
|
||||
|
||||
If tests get interrupted, manually clean up:
|
||||
```bash
|
||||
# Delete all e2e test namespaces
|
||||
kubectl delete namespace -l kubemirror-e2e-test=true
|
||||
|
||||
# Delete test resources in default namespace
|
||||
kubectl delete secret,configmap -n default -l kubemirror.raczylo.com/enabled=true
|
||||
|
||||
# Kill controller if still running
|
||||
pkill kubemirror
|
||||
```
|
||||
|
||||
### Individual test fails
|
||||
|
||||
Run test with verbose output to see which assertion failed:
|
||||
```bash
|
||||
bash -x ./test-basic-mirroring.sh
|
||||
```
|
||||
|
||||
Check controller logs for errors:
|
||||
```bash
|
||||
grep -i error /tmp/kubemirror-e2e-test.log
|
||||
```
|
||||
|
||||
## Adding New Test Scenarios
|
||||
|
||||
The DRY framework makes it easy to add new test scenarios. Here's how:
|
||||
|
||||
### Example: Add a new scenario
|
||||
|
||||
```bash
|
||||
# In test-comprehensive.sh, add a new scenario block:
|
||||
|
||||
run_test_scenario "23: Your new scenario description"
|
||||
|
||||
# Use framework functions to set up test conditions
|
||||
create_test_namespace e2e-new-ns
|
||||
create_source secret test-new default true true "e2e-new-ns" "test-data"
|
||||
|
||||
# Perform the action you want to test
|
||||
update_source_annotations secret test-new default true "e2e-new-ns,e2e-new-ns-2"
|
||||
|
||||
# Verify expected results
|
||||
verify_mirrors_exist secret test-new e2e-new-ns e2e-new-ns-2
|
||||
|
||||
complete_test_scenario "23" "pass"
|
||||
```
|
||||
|
||||
### Framework Functions Reference
|
||||
|
||||
**Resource Creation:**
|
||||
```bash
|
||||
create_source secret my-secret default true true "ns1,ns2" "data"
|
||||
# ↑ ↑ ↑ ↑ ↑ ↑ ↑
|
||||
# type name ns lbl ann targets data
|
||||
```
|
||||
|
||||
**Resource Updates:**
|
||||
```bash
|
||||
update_source_labels secret my-secret default true # Set enabled=true
|
||||
update_source_labels secret my-secret default false # Set enabled=false
|
||||
update_source_labels secret my-secret default "" # Remove label
|
||||
|
||||
update_source_annotations secret my-secret default true "ns1,ns2" # Enable sync
|
||||
update_source_annotations secret my-secret default false "" # Set sync=false
|
||||
update_source_annotations secret my-secret default "" "" # Remove annotation
|
||||
|
||||
update_source_data secret my-secret default "new-data-v2"
|
||||
```
|
||||
|
||||
**Namespace Operations:**
|
||||
```bash
|
||||
create_test_namespace my-ns true # Create with allow-mirrors=true
|
||||
create_test_namespace my-ns false # Create with allow-mirrors=false
|
||||
create_test_namespace my-ns "" # Create with no label
|
||||
|
||||
update_namespace_labels my-ns true # Set allow-mirrors=true
|
||||
update_namespace_labels my-ns false # Set allow-mirrors=false
|
||||
update_namespace_labels my-ns "" # Remove label
|
||||
```
|
||||
|
||||
**Verification:**
|
||||
```bash
|
||||
verify_mirrors_exist secret my-secret ns1 ns2 ns3
|
||||
verify_mirrors_not_exist secret my-secret ns4 ns5
|
||||
verify_mirror_data secret my-secret default target-ns "expected-data"
|
||||
verify_orphan_cleanup secret my-secret orphan-ns1 orphan-ns2
|
||||
```

## Test Methodology
|
||||
|
||||
### Systematic Approach
|
||||
|
||||
The test framework follows a systematic approach:
|
||||
|
||||
1. **State Setup**: Create namespaces and resources in known state
|
||||
2. **Action**: Perform the operation being tested (create, update, delete, label change)
|
||||
3. **Verification**: Assert expected outcomes using verification functions
|
||||
4. **Cleanup**: Automatic cleanup via trap handlers
|
||||
|
||||
### DRY Principles
|
||||
|
||||
- **Reusable functions**: All operations abstracted into framework functions
|
||||
- **Data-driven**: Test scenarios are data, not code
|
||||
- **Composable**: Combine framework functions to create complex scenarios
|
||||
- **Maintainable**: Add new scenarios without duplicating code
|
||||
|
||||
### Coverage Strategy
|
||||
|
||||
Tests systematically cover:
|
||||
- **Happy path**: Expected behavior under normal conditions
|
||||
- **Edge cases**: Boundary conditions and unusual states
|
||||
- **Error conditions**: Invalid inputs, missing resources, conflicts
|
||||
- **State transitions**: All possible state changes (no labels → labels → annotations, etc.)
|
||||
- **Concurrent operations**: Namespace creation during reconciliation, multiple updates
|
||||
|
||||
## Test Utilities Reference
|
||||
|
||||
### Common Utilities (`common.sh`)
|
||||
|
||||
**Logging:**
|
||||
- `log_info <message>`: Blue informational message
|
||||
- `log_success <message>`: Green success message (increments pass count)
|
||||
- `log_fail <message>`: Red failure message (increments fail count)
|
||||
- `log_warn <message>`: Yellow warning message
|
||||
|
||||
**Assertions:**
|
||||
- `assert_resource_exists <type> <name> <namespace>`
|
||||
- `assert_resource_not_exists <type> <name> <namespace>`
|
||||
- `assert_annotation_exists <type> <name> <namespace> <annotation_key>`
|
||||
- `assert_label_exists <type> <name> <namespace> <label_key> <expected_value>`
|
||||
- `assert_data_matches <type> <source_name> <source_ns> <target_name> <target_ns> <data_key>`
|
||||
|
||||
**Waiting:**
|
||||
- `wait_for_resource <type> <name> <namespace> [timeout]`
|
||||
- `wait_for_resource_deletion <type> <name> <namespace> [timeout]`
|
||||
|
||||
**Utilities:**
|
||||
- `cleanup_namespace <namespace>`
|
||||
- `cleanup_resource <type> <name> <namespace>`
|
||||
- `check_context`: Verify running on docker-desktop
|
||||
- `print_summary`: Print test results summary
|
||||
|
||||
## CI/CD Integration
|
||||
|
||||
To run tests in CI:
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
set -e
|
||||
|
||||
# Start kind cluster or use existing k8s
|
||||
kind create cluster --name kubemirror-test
|
||||
|
||||
# Switch context
|
||||
kubectl config use-context kind-kubemirror-test
|
||||
|
||||
# Run tests
|
||||
cd e2e
|
||||
./run-all-tests.sh
|
||||
|
||||
# Cleanup
|
||||
kind delete cluster --name kubemirror-test
|
||||
```
|
||||
|
||||
## Performance Notes
|
||||
|
||||
- Comprehensive test suite: ~3-5 minutes
|
||||
- Controller startup: ~10 seconds
|
||||
- Resource reconciliation: typically <5 seconds per operation
|
||||
- Total assertions: 60+ across all scenarios
|
||||
- Each scenario includes setup, action, verification, and cleanup phases
|
||||
|
||||
## Test Isolation and Cleanup
|
||||
|
||||
- **Automatic cleanup**: All resources cleaned up via trap handlers
|
||||
- **Namespace isolation**: Tests use `e2e-*` prefixed namespaces
|
||||
- **Sequential execution**: Tests run sequentially to avoid race conditions
|
||||
- **Idempotent**: Tests can be re-run without manual cleanup
|
||||
- **Resource labeling**: Test resources labeled for easy identification
|
||||
|
||||
## Known Limitations
|
||||
|
||||
- Tests assume clean docker-desktop cluster (or equivalent local cluster)
|
||||
- Some scenarios require waiting for reconciliation (30s default timeout)
|
||||
- Tests are sequential (not parallel) to ensure deterministic behavior
|
||||
- Controller must be stopped between runs if running manually (run-all-tests.sh handles this)
