## Purpose and Use Cases

Tekton is a core component of the cloud-native ecosystem, serving as a Kubernetes-native CI/CD pipeline framework that enables declarative, container-based pipeline definitions.

### What Problem Does It Solve?

The need for a Kubernetes-native CI/CD solution that leverages containers for pipeline execution, integrates naturally with Kubernetes tooling, and provides declarative pipeline definitions.

### When to Use This Project

Use Tekton when you need a Kubernetes-native CI/CD pipeline framework, want to run pipelines in Kubernetes pods, or need declarative pipeline definitions that integrate with Kubernetes RBAC and security.

### Key Use Cases


- Kubernetes-native CI/CD pipelines
- Declarative pipeline definitions
- Container-based pipeline execution
- Integration with Git and artifact repositories
- Parallel and sequential task execution


---

## Architecture Design Patterns

### Core Components


- **Pipeline**: Sequence of tasks to execute
- **Task**: Reusable sequence of steps
- **Step**: Container that runs a command
- **PipelineRun**: Instance of a pipeline execution
- **TaskRun**: Instance of a task execution
- **PipelineResource**: Input/output resources for pipelines
- **ClusterTask**: Cluster-scoped task definition


### Component Interactions


1. **User → API Server**: Creates PipelineRun
2. **Pipeline Controller → TaskRun**: Creates task instances
3. **TaskRun → Kubernetes**: Creates pod for each step
4. **Step Pod → Container Runtime**: Runs container commands
5. **Result → Artifact Storage**: Saves outputs
6. **Status → API Server**: Updates PipelineRun status


### Data Flow Patterns


1. **Pipeline Execution**: PipelineRun created → TaskRuns created → Pods created → Steps run → Results stored
2. **Resource Processing**: Input resource → Task → Output resource → Pipeline → Next task
3. **Status Updates**: Pod status → TaskRun → PipelineRun → API Server


### Design Principles


- **Kubernetes-Native**: Uses Kubernetes API patterns
- **Container-Based**: Each step in its own container
- **Declarative**: YAML-based definitions
- **Composable**: Tasks and pipelines can be composed
- **Flexible**: Supports any container workload


---

## Integration Approaches

### Integration with Other CNCF Projects


- **Kubernetes**: Native Kubernetes CRDs
- **Git Providers**: GitHub, GitLab, Bitbucket integration
- **Container Runtime**: Runs pipelines in pods

- **Helm**: Chart deployment in pipelines


### API Patterns


- **Kubernetes API**: Custom resource definitions
- **Status Subresource**: Pipeline run status
- **Finalizers**: Cleanup operations
- **Owner References**: Resource relationships


### Configuration Patterns


- **Pipeline YAML**: Pipeline definitions
- **PipelineRun YAML**: Pipeline instances

- **Testing**: Pipeline testing strategies


### Security Pitfalls


- **Service Accounts**: Overly permissive service accounts
- **Pipeline Resources**: Secrets in resources
- **Task Execution**: Privileged task containers
- **Network Exposure**: Access to internal services


---

## Coding Practices

### Idiomatic Configuration


- **YAML Definitions**: Clear structure
- **Task Parameters**: Typed parameters
- **Pipeline Resources**: Explicit inputs/outputs
- **ServiceAccount References**: Explicit auth


### API Usage Patterns


- **kubectl**: Pipeline operations
- **Tekton CLI**: Extended functionality
- **Kubernetes API**: Direct API access
- **Webhooks**: Event triggers


### Observability Best Practices


- **PipelineRun Logs**: Task execution logs
- **Status Metrics**: Run duration and status
- **Resource Usage**: Task resource consumption
- **Event Logging**: Trigger events


### Testing Strategies


- **Unit Tests**: Task and pipeline tests
- **Integration Tests**: Controller tests
- **E2E Tests**: Full pipeline runs
- **Compatibility Tests**: Kubernetes versions


### Development Workflow


- **Development**: Tekton development cluster
- **Testing**: Go tests, E2E tests

## When to Use

Use this skill when:

- **Integrating a CNCF project into Kubernetes infrastructure** — You need to configure, deploy, or troubleshoot a cloud-native tool within a cluster
- **Designing cloud-native architecture** — You are selecting and integrating CNCF tools to solve specific infrastructure challenges
- **Resolving operational issues** — A CNCF component is misbehaving, underperforming, or needs configuration changes
---

## Core Workflow

1. **Assess Requirements** — Understand the use case, scale, integration needs, and existing infrastructure. **Checkpoint:** Document requirements, constraints, and success criteria.

2. **Design Architecture** — Plan component interactions, data flow, and deployment strategy using cloud-native best practices. **Checkpoint:** Verify the architecture addresses all requirements and follows CNCF conventions.

3. **Implement & Configure** — Create manifests, configurations, and deployment scripts. Include resource limits, health checks, and observability hooks. **Checkpoint:** Validate all YAML against schema and test in a staging environment.

4. **Deploy & Monitor** — Apply manifests to the cluster, verify component health, and confirm observability is working. **Checkpoint:** Confirm all pods/services are running, probes passing, and metrics/alerts configured.

---

## Constraints

### MUST DO
- Include at least one complete working YAML manifest example
- Note when content is auto-generated vs. manually verified
- Reference relevant CNCF project documentation

### MUST NOT DO
- Deploy manifests without testing in a staging environment first
- Use deprecated API versions (e.g., apps/v1beta1)
- Omit resource limits and requests in Kubernetes manifests
