# Innoventions - Tekton CI/CD Platform
**Service Theme:** Innoventions (EPCOT Innovation Hub)
**Dashboard DNS:** mission-space.local.mk-labs.cloud (Mission: SPACE control center)
**Namespace:** innoventions
**Wave:** 8 (after Harbor wave 7)
**Phase:** Platform Buildout Phase 2
---
## Overview
Tekton Pipelines provides the CI/CD brain of the mk-labs platform. It builds containers from Git repositories (Gitea) and pushes images to Harbor registry, enabling automated workflows triggered by webhooks.
**Key capabilities:**
- Container image builds from source (Kaniko)
- Automated webhook triggers from Gitea
- Reusable task library for common operations
- Web dashboard for pipeline monitoring and management
- Integration with Harbor registry for image storage
---
## Component Versions
**Installation Date:** June 6, 2026
**Deployed By:** Rocket Raccoon (CI/CD Specialist)
| Component | Version | Notes |
|-----------|---------|-------|
| Tekton Operator | v0.79.1 | Latest stable (May 2026) |
| Tekton Pipelines | v1.13.0 | Managed by operator |
| Tekton Triggers | v0.36.0 | Managed by operator |
| Tekton Dashboard | v0.69.0 | Managed by operator |
| Kaniko Executor | v1.24.0 | For rootless container builds |
**Version pinning policy:** All versions explicitly pinned. No `latest` tags.
**Compatibility verified:**
- Tekton Operator v0.79.1 supports Kubernetes 1.27+
- Fastpass cluster running Talos Kubernetes 1.30+
- Compatible with existing Gateway API (wave 4)
---
## Architecture
### Installation Method: Tekton Operator
Tekton is deployed via the official Tekton Operator, not Helm charts or raw manifests.
**Rationale:**
- Official Tekton project support
- Automated component lifecycle management
- Proven upgrade path
- Single TektonConfig CR manages all components
**Pattern:**
1. ArgoCD deploys operator manifest (operator-install.yaml)
2. ArgoCD applies TektonConfig CR (tektonconfig.yaml)
3. Operator deploys and manages Pipelines, Triggers, Dashboard
### Components Enabled
Via TektonConfig `profile: all`:
- **Pipelines:** Core task/pipeline execution engine
- **Triggers:** Webhook EventListener for Git events
- **Dashboard:** Web UI for monitoring and management
- **Chains:** Disabled (planned for Phase 3 - image signing)
### Integration Points
**Harbor Container Registry:**
- URL: the-seas.local.mk-labs.cloud
- Robot account: tekton-builder
- Projects: library, platform, applications
- Credentials: ExternalSecret from 1Password
**Gitea Source Control:**
- Webhook integration via EventListener
- Clone tasks pull from Gitea repos
- Webhook secret validation
**Gateway API:**
- Dashboard exposed via HTTPRoute
- TLS certificate from cert-manager
- Hostname: mission-space.local.mk-labs.cloud
**Storage:**
- PVC-backed workspaces using nfs-emporium StorageClass
- 7-day retention for completed PipelineRuns
- Auto-cleanup to manage disk usage

Static YAML from: https://github.com/tektoncd/operator/releases/v0.79.1
- CRDs for TektonConfig, TektonPipeline, etc.
- Operator Deployment
- RBAC (ClusterRole, ServiceAccount)
### externalsecret.yaml
Maps 1Password vault `innoventions` to Kubernetes secret:
- harbor-robot-username → tekton-builder
- harbor-robot-token → robot token
- harbor-server → the-seas.local.mk-labs.cloud
- Creates docker-registry secret for Kaniko
### dashboard-httproute.yaml
Gateway API HTTPRoute:

---
## Reusable Pipeline Library
Tasks and Pipelines live in `cluster/tekton/` for reuse across the homelab:
**cluster/tekton/tasks/**
- git-clone.yaml - Clone repository from Gitea
- kaniko-build.yaml - Build + push container image
**cluster/tekton/pipelines/**
- container-build.yaml - Complete build workflow
**cluster/tekton/triggers/**

tkn pipelinerun list -n innoventions
```
---
## Testing & Verification
### Health Checks
**Operator status:**
```bash
kubectl get tektonconfig -n innoventions
kubectl get pods -n innoventions
```
**Expected pods:**
- tekton-operator-*
- tekton-pipelines-controller-*
- tekton-pipelines-webhook-*
- tekton-triggers-controller-*
- tekton-triggers-webhook-*
- tekton-dashboard-*
**ArgoCD sync:**
```bash
kubectl get applications -n argocd innoventions
```
### Manual Pipeline Test
1. Create test workspace:
```bash
kubectl apply -f - <<EOF
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: test-workspace
namespace: innoventions
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 1Gi
storageClassName: nfs-emporium
EOF
```
2. Run container-build pipeline (see CLI commands above)
3. Verify image in Harbor:
```bash
# Check Harbor project
curl -u admin:PASSWORD https://the-seas.local.mk-labs.cloud/api/v2.0/projects/library/repositories
```
### Webhook Integration Test
1. Configure Gitea webhook:
- URL: http://el-gitea-listener.innoventions.svc.cluster.local:8080
- Secret: (from 1Password vault `innoventions`)
- Events: Push
2. Push to repository:
```bash
git commit --allow-empty -m "Test webhook trigger"
git push
```
3. Watch for automatic PipelineRun:
```bash
kubectl get pipelinerun -n innoventions -w
```
---
## Troubleshooting
### Operator Not Deploying Components
**Check TektonConfig status:**
```bash
kubectl describe tektonconfig config -n innoventions
```
**Check operator logs:**
```bash
kubectl logs -l app=tekton-operator -n innoventions
```
### Harbor Push Fails
**Verify secret exists:**
```bash
kubectl get secret harbor-credentials -n innoventions -o yaml
```
**Test credentials manually:**
```bash
# Extract credentials
kubectl get secret harbor-credentials -n innoventions -o jsonpath='{.data.\.dockerconfigjson}' | base64 -d
# Test login
docker login the-seas.local.mk-labs.cloud -u robot\$tekton-builder -p TOKEN
```
### Webhook Not Triggering
**Check EventListener logs:**
```bash
kubectl logs -l eventlistener=gitea-listener -n innoventions -f
```
**Verify webhook secret matches:**
- Gitea webhook secret
- 1Password vault `innoventions` field `gitea-webhook-secret`
**Check webhook delivery in Gitea UI:**
- Repository → Settings → Webhooks → Recent Deliveries
### Dashboard Not Accessible
**Check HTTPRoute:**
```bash
kubectl get httproute -n innoventions
kubectl describe httproute tekton-dashboard -n innoventions
```
**Check certificate:**
```bash
kubectl get certificate -n innoventions
```
**Check DNS resolution:**
```bash
dig mission-space.local.mk-labs.cloud
```

# Tekton Pipeline Library
Reusable Tekton Pipelines for common workflows across the mk-labs homelab.
---
## Overview
Pipelines orchestrate multiple Tasks into a complete workflow. They define the sequence, data flow, and conditions for task execution.
**Key characteristics:**
- Compose multiple tasks into workflows
- Define parameters passed to tasks
- Manage workspaces shared between tasks
- Support parallel and sequential execution
- Can be triggered manually or via webhooks
---
## Available Pipelines
### container-build.yaml
Complete container image build workflow from Git source to Harbor registry.
**What it does:**
1. Clone Git repository (git-clone task)
2. Build container image with Kaniko (kaniko-build task)
3. Push image to Harbor registry
**Parameters:**
- `git-url` - Git repository URL
- `git-revision` - Branch, tag, or commit (default: main)
- `image-name` - Target image name (without tag)
- `image-tag` - Image tag (default: latest)
**Workspaces:**
- `shared-workspace` - Shared between clone and build steps
**Usage (manual):**
```bash
tkn pipeline start container-build \
--param git-url=https://gitea.mk-labs.cloud/rblundon/my-app.git \
--param git-revision=main \
--param image-name=the-seas.local.mk-labs.cloud/library/my-app \
--param image-tag=v1.0.0 \
--workspace name=shared-workspace,volumeClaimTemplateFile=workspace-template.yaml \
--showlog \
--namespace innoventions
```
**Usage (from another pipeline):**
```yaml
tasks:
- name: build-my-app
taskRef:
name: container-build
params:
- name: git-url
value: $(params.repo-url)
- name: image-tag
value: $(params.version)
```
---
## Pipeline Execution Model
**Sequential tasks:**
```yaml
tasks:
- name: first
taskRef:
name: some-task
- name: second
runAfter:
- first
taskRef:
name: another-task
```
**Parallel tasks:**
```yaml
tasks:
- name: lint
taskRef:
name: golangci-lint
- name: test
taskRef:
name: go-test
# Both run in parallel
```
**Conditional execution:**
```yaml
tasks:
- name: deploy-to-prod
when:
- input: "$(params.environment)"
operator: in
values: ["production"]
taskRef:
name: deploy
```
---
## Creating New Pipelines
Basic pipeline structure:
```yaml
apiVersion: tekton.dev/v1beta1
kind: Pipeline
metadata:
name: my-pipeline
namespace: innoventions
spec:
params:
- name: my-param
description: Parameter description
default: default-value
workspaces:
- name: shared-data
description: Workspace shared between tasks
tasks:
- name: step1
taskRef:
name: some-task
params:
- name: task-param
value: $(params.my-param)
workspaces:
- name: output
workspace: shared-data
- name: step2
runAfter:
- step1
taskRef:
name: another-task
workspaces:
- name: source
workspace: shared-data
```
**Best practices:**
- Keep pipelines focused on a single workflow
- Use meaningful task names that describe the action
- Document parameters and expected values
- Consider workspace size requirements
- Test manually before setting up webhooks
---
## Workspace Management
Pipelines require workspace storage for sharing data between tasks.
**Option 1: VolumeClaimTemplate (recommended for webhooks)**
```yaml
workspaces:
- name: shared-workspace
volumeClaimTemplate:
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 1Gi
storageClassName: nfs-emporium
```
**Option 2: Existing PVC (for manual runs)**
```yaml
workspaces:
- name: shared-workspace
persistentVolumeClaim:
claimName: my-workspace-pvc
```
**Option 3: EmptyDir (for ephemeral data)**
```yaml
workspaces:
- name: shared-workspace
emptyDir: {}
```
---
## Monitoring Pipeline Runs
**List recent runs:**
```bash
tkn pipelinerun list -n innoventions
```
**Get run details:**
```bash
tkn pipelinerun describe BUILD-NAME -n innoventions
```
**Follow logs:**
```bash
tkn pipelinerun logs BUILD-NAME -f -n innoventions
```
**Delete old runs:**
```bash
kubectl delete pipelinerun -n innoventions --field-selector=status.conditions[0].reason=Succeeded
```
---
## Pipeline Templates
Create parameterized templates for common patterns:
```yaml
apiVersion: tekton.dev/v1beta1
kind: Pipeline
metadata:
name: template-container-build
namespace: innoventions
labels:
type: template
spec:
params:
- name: git-url
- name: git-revision
default: main
- name: harbor-project
default: library
- name: app-name
- name: version
tasks:
- name: clone-source
taskRef:
name: git-clone
params:
- name: url
value: $(params.git-url)
- name: revision
value: $(params.git-revision)
workspaces:
- name: output
workspace: workspace
- name: build-and-push
runAfter:
- clone-source
taskRef:
name: kaniko-build
params:
- name: image
value: the-seas.local.mk-labs.cloud/$(params.harbor-project)/$(params.app-name):$(params.version)
workspaces:
- name: source
workspace: workspace
workspaces:
- name: workspace
```
---
## Integration with Triggers
Pipelines can be automatically triggered by webhooks via Tekton Triggers.
See: `cluster/tekton/triggers/` for EventListener, TriggerBinding, and TriggerTemplate configurations.
**Flow:**
1. Git push to Gitea
2. Gitea sends webhook to EventListener
3. TriggerBinding extracts event data (repo URL, commit SHA)
4. TriggerTemplate creates PipelineRun with extracted parameters
5. Pipeline executes automatically
---
## Future Pipeline Ideas
**Multi-stage builds:**
- Build → Test → Scan → Push
- Conditional deployment based on test results
**Multi-arch builds:**
- Build for amd64 and arm64
- Create multi-arch manifest
**Monorepo support:**
- Detect changed directories
- Build only affected services
**Advanced workflows:**
- Helm chart linting and publishing
- Documentation generation
- Release artifact creation
- Changelog generation
---
## Troubleshooting
**Pipeline fails to start:**
- Check task references exist
- Verify workspace configuration
- Check RBAC permissions
**Tasks timeout:**
- Increase timeout in pipeline spec
- Check for stuck processes in task logs
**Workspace errors:**
- Verify StorageClass exists
- Check NFS CSI driver status
- Ensure PVC can be created
**Image push fails:**
- Verify harbor-credentials secret exists
- Test credentials manually with docker login
- Check Harbor project permissions

- `harbor-credentials` - Docker config JSON for Harbor authentication
**Usage:**
```yaml
tasks:
- name: build-image
taskRef:
name: kaniko-build
params:
- name: image
value: the-seas.local.mk-labs.cloud/library/my-app:v1.0
- name: dockerfile
value: ./Dockerfile
workspaces:
- name: source
workspace: shared-workspace
```
---
## Testing Tasks Standalone
Each task can be tested independently before integrating into pipelines.
**Example: Test git-clone**
1. Create test workspace:
```bash
kubectl apply -f - <<EOF
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: test-workspace
namespace: innoventions
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 500Mi
storageClassName: nfs-emporium
EOF
```
2. Run task:
```bash
tkn task start git-clone \
--param url=https://gitea.mk-labs.cloud/rblundon/homelab.git \
--param revision=main \
--workspace name=output,claimName=test-workspace \
--showlog \
--namespace innoventions
```
3. Inspect result:
```bash
# Create debug pod
kubectl run -it --rm debug --image=busybox --restart=Never \
--overrides='{"spec":{"volumes":[{"name":"workspace","persistentVolumeClaim":{"claimName":"test-workspace"}}],"containers":[{"name":"debug","image":"busybox","stdin":true,"tty":true,"volumeMounts":[{"name":"workspace","mountPath":"/workspace"}]}]}}' \
-n innoventions -- sh
# Inside pod:
ls -la /workspace
```
---
## Creating New Tasks
Follow the Tekton Task specification:
```yaml
apiVersion: tekton.dev/v1beta1
kind: Task
metadata:
name: my-task
namespace: innoventions
spec:
params:
- name: my-param
description: Parameter description
default: default-value
workspaces:
- name: my-workspace
description: Workspace description
steps:
- name: step-name
image: container-image:tag
script: |
#!/bin/sh
echo "Task logic here"
echo "Param value: $(params.my-param)"
ls $(workspaces.my-workspace.path)
```
**Best practices:**
- Pin container image versions (no `:latest`)
- Provide parameter defaults where sensible
- Document parameters and workspaces clearly
- Use script blocks for complex shell logic
- Test standalone before using in pipelines
---
## Task Catalog Reference
Official Tekton task catalog: https://hub.tekton.dev/
**Popular tasks to consider adding:**
- `buildpacks` - Build images without Dockerfile
- `helm-upgrade` - Deploy Helm charts
- `trivy-scanner` - Scan images for vulnerabilities
- `git-cli` - Advanced Git operations
- `pytest` - Run Python tests
**Installation from catalog:**
```bash
kubectl apply -f https://raw.githubusercontent.com/tektoncd/catalog/main/task/TASK-NAME/VERSION/TASK-NAME.yaml
```
---
## Version Management
All task image references should be pinned to specific versions.
**Current image versions:**
- Git init: `gcr.io/tekton-releases/github.com/tektoncd/pipeline/cmd/git-init:v0.43.0`
- Kaniko: `gcr.io/kaniko-project/executor:v1.24.0`
**Update procedure:**
1. Check for new image releases
2. Update task YAML with new version
3. Test standalone
4. Commit and deploy via ArgoCD

# Tekton Triggers Library
Webhook integration for automatic pipeline execution from Git events.
---
## Overview
Tekton Triggers enable event-driven CI/CD by listening for webhooks from Git providers (Gitea, GitHub, GitLab) and automatically starting pipeline runs.
**Components:**
- **EventListener** - HTTP endpoint that receives webhooks
- **TriggerBinding** - Extracts data from webhook payload
- **TriggerTemplate** - Creates PipelineRun from extracted data
**Flow:**
```
Git Push → Gitea Webhook → EventListener → TriggerBinding → TriggerTemplate → PipelineRun
```
---
## Available Triggers
### gitea-listener (EventListener)
HTTP service that receives webhooks from Gitea.
**Endpoint:** `http://el-gitea-listener.innoventions.svc.cluster.local:8080`
**Supported events:**
- Push (branch commits)
- Tag creation (future)
- Pull request (future)
**Security:**
- Validates webhook secret from 1Password
- Only processes push events
- Uses Gitea interceptor for payload validation
---
### gitea-binding (TriggerBinding)
Extracts information from Gitea webhook payload.
**Extracted parameters:**
- `git-repo-url` - Repository clone URL
- `git-revision` - Commit SHA
- `repo-name` - Repository name (for image naming)
**Gitea webhook payload structure:**
```json
{
"repository": {
"clone_url": "https://gitea.mk-labs.cloud/rblundon/my-app.git",
"name": "my-app"
},
"after": "abc123def456...",
"ref": "refs/heads/main"
}
```
---
### gitea-template (TriggerTemplate)
Creates a PipelineRun when webhook is received.
**What it creates:**
- PipelineRun with generateName (unique per trigger)
- Parameters from TriggerBinding
- Workspace using volumeClaimTemplate (auto-created)
**Image naming convention:**
- Target: `the-seas.local.mk-labs.cloud/library/REPO-NAME`
- Tag: Git commit SHA (enables traceability)
---
## Configuring Gitea Webhooks
**Per-repository setup:**
1. Navigate to repository in Gitea
2. Settings → Webhooks → Add Webhook → Gitea
3. Configure:
- **URL:** `http://el-gitea-listener.innoventions.svc.cluster.local:8080`
- **HTTP Method:** POST
- **Content Type:** application/json
- **Secret:** (get from 1Password vault `innoventions`, field `gitea-webhook-secret`)
- **Trigger On:** Push events
- **Branch filter:** (leave empty for all branches, or specify like `main`)
- **Active:** ✓ Enabled
4. Click "Add Webhook"
5. Test with "Test Delivery" button
**Webhook URL alternatives:**
- Inside cluster: `http://el-gitea-listener.innoventions.svc.cluster.local:8080`
- Via Gateway (if exposed): TBD in future phase
---
## Testing Webhook Integration
**1. Check EventListener is running:**
```bash
kubectl get pods -l eventlistener=gitea-listener -n innoventions
kubectl get svc el-gitea-listener -n innoventions
```
**2. Watch EventListener logs:**
```bash
kubectl logs -l eventlistener=gitea-listener -n innoventions -f
```
**3. Make a test commit:**
```bash
cd /path/to/repo
git commit --allow-empty -m "Test webhook trigger"
git push origin main
```
**4. Verify PipelineRun created:**
```bash
kubectl get pipelinerun -n innoventions -w
```
**5. Check webhook delivery in Gitea:**
- Repository → Settings → Webhooks → Click webhook
- View "Recent Deliveries" tab
- Should show 200 OK response
---
## Debugging Webhooks
**Webhook not triggering:**
1. **Check EventListener logs:**
```bash
kubectl logs -l eventlistener=gitea-listener -n innoventions --tail=100
```
Look for:
- Incoming requests
- Secret validation failures
- TriggerBinding errors
2. **Verify webhook secret:**
```bash
# Get secret from Kubernetes
kubectl get secret gitea-webhook-secret -n innoventions -o jsonpath='{.data.secret}' | base64 -d
# Compare with 1Password vault `innoventions` field
```
3. **Check Gitea webhook deliveries:**
- Green checkmark = successful
- Red X = failed
- Click delivery to see request/response details
4. **Test EventListener directly:**
```bash
# From within cluster
kubectl run -it --rm curl --image=curlimages/curl --restart=Never -- \
curl -X POST http://el-gitea-listener.innoventions.svc.cluster.local:8080 \
-H "Content-Type: application/json" \
-H "X-Gitea-Event: push" \
-d '{"repository":{"clone_url":"https://gitea.mk-labs.cloud/rblundon/test.git","name":"test"},"after":"abc123"}'
```
**PipelineRun created but fails:**
1. **Check PipelineRun details:**
```bash
kubectl describe pipelinerun -n innoventions PIPELINERUN-NAME
```
2. **Check task logs:**
```bash
tkn pipelinerun logs PIPELINERUN-NAME -n innoventions
```
3. **Common issues:**
- Git clone fails: Check Gitea connectivity, credentials
- Image build fails: Check Dockerfile syntax
- Image push fails: Check Harbor credentials

## Customizing Triggers
### Add Tag Triggers
Create separate trigger for Git tags:
```yaml
apiVersion: triggers.tekton.dev/v1beta1
kind: EventListener
metadata:
name: gitea-listener
spec:
triggers:
- name: gitea-push
# ... existing push trigger
- name: gitea-tag
interceptors:
- ref:
name: gitea
params:
- name: secretRef
value:
secretName: gitea-webhook-secret
secretKey: secret
- name: eventTypes
value:
- create # Tag creation
bindings:
- ref: gitea-tag-binding
template:
ref: gitea-tag-template
```
### Filter by Branch
Only trigger on specific branches:
```yaml
apiVersion: triggers.tekton.dev/v1beta1
kind: EventListener
spec:
triggers:
- name: gitea-main-branch
interceptors:
- ref:
name: gitea
- ref:
name: cel
params:
- name: filter
value: "body.ref == 'refs/heads/main'"
# ... rest of config
```
### Custom Image Tagging
Modify TriggerTemplate to use semantic versioning:
```yaml
apiVersion: triggers.tekton.dev/v1beta1
kind: TriggerTemplate
spec:
params:
- name: git-revision
- name: repo-name
resourcetemplates:
- apiVersion: tekton.dev/v1beta1
kind: PipelineRun
spec:
params:
- name: image-tag
value: "$(tt.params.git-revision)-$(date +%Y%m%d-%H%M%S)"
```
---
## Security Considerations
**Webhook secret validation:**
- ALWAYS use webhook secrets
- Rotate secrets periodically
- Store in 1Password, sync via ExternalSecret
**Network policies:**
- EventListener only accessible from Gitea
- Consider adding NetworkPolicy to restrict access
**RBAC:**
- EventListener ServiceAccount has minimal permissions
- Can only create PipelineRuns in innoventions namespace
**Resource limits:**
- Consider rate limiting in future (max runs per hour)
- Set PipelineRun timeouts to prevent runaway builds
---
## Monitoring & Observability
**EventListener metrics:**
```bash
# Prometheus metrics endpoint
kubectl port-forward svc/el-gitea-listener 8080:8080 -n innoventions
curl http://localhost:8080/metrics
```
**Key metrics:**
- `eventlistener_triggered_total` - Total webhooks processed
- `eventlistener_event_count` - Events by type
- `tekton_pipelinerun_duration_seconds` - Build duration
**Logs aggregation:**
- EventListener logs show webhook receipt
- PipelineRun logs show build execution
- Consider centralizing logs (Loki/ELK in future)
---
## Advanced Patterns
**Multi-pipeline triggers:**
Trigger different pipelines based on event type:
- Push to main → Production build
- Push to dev → Development build
- PR created → Test run only
**Conditional execution:**
Use CEL interceptors to filter:
- Only build if Dockerfile changed
- Skip builds for doc-only commits
- Build specific services in monorepo
**Fan-out builds:**
One webhook triggers multiple pipelines:
- Build multiple architectures
- Build and deploy to multiple environments
- Run parallel test suites
