Tekton Learning Roadmap

Goal: From zero Tekton experience to production-grade Kubernetes-native CI/CD

Learning Phases

Phase 1: Tekton Fundamentals (2-3 days)

•Core objects — Task, Pipeline, PipelineRun, Trigger

•Tekton vs. Jenkins vs. GitHub Actions — the no-central-server distinction

•ClusterTask for cross-namespace reuse

•Workspace for sharing data between Tasks

Phase 2: Triggers and Event-Driven Pipelines (2-3 days)

•Installing and configuring Tekton Triggers

•EventListener, TriggerBinding, TriggerTemplate

•Webhook-driven PipelineRun creation

Phase 3: Intermediate Pipeline Design (3-4 days)

•Matrix strategy for parameterized fan-out execution

•Timeouts and cancellation

•finally tasks for cleanup/notification regardless of outcome

•Tekton Results for querying historical run data

•Sidecars for auxiliary containers alongside a Task's steps

Phase 4: Advanced Production Operations (1 week)

•Tekton Chains for supply-chain provenance and signing

•Multi-tenant RBAC design

•Affinity Assistant and pod-template performance tuning

•Tekton Operator for lifecycle management

Phase 5: Troubleshooting and Interview Readiness (ongoing)

•Diagnosing failed TaskRun/PipelineRun pods with kubectl describe

•Practice explaining the "no central server, every step is a pod" architecture clearly — this is Tekton's single biggest differentiator and a near-certain interview topic

Job Roles This Enables

•CI/CD Engineer (Kubernetes-native focus)

•Platform Engineer building internal CI/CD on Kubernetes

•DevOps Engineer, especially in OpenShift environments

Target Certifications

(needs verification — recheck against current source for CNCF's current Tekton-relevant certification offerings, if any)

How to Use This Roadmap

1.Work through phases in order — Phase 3's matrix/finally/Results features assume Phase 1's core object model and Phase 2's trigger mechanics are already solid

2.This technology doesn't have a separate Labs tab — the Fundamentals/Intermediate/Advanced code blocks and a real cluster (local kind/minikube works) are the hands-on material

3.Build the portfolio projects in projects.md after Phase 3 — a real webhook-triggered pipeline with matrix execution demonstrates meaningfully more than a manually-invoked single Task

4.Since every Tekton execution is a real Kubernetes pod, practice debugging failed runs with kubectl describe/kubectl logs directly rather than relying on the optional Dashboard — this mirrors how you'd actually debug it in a cluster without the Dashboard installed

5.Phase 4's Tekton Chains (supply-chain provenance) is increasingly relevant to security-conscious interviews — don't treat it as optional advanced trivia

Prerequisites

See prerequisites.md in this section for what you should know before starting.

Revision Notes

Total time: 3-4 weeks (part-time)
Because there's no central CI server, "where do I look when something
fails" always resolves to a specific pod — internalizing that mental
model early makes every later troubleshooting scenario faster
