quarkus-tekton-pipeline-example

Example of Tekton pipeline for Quarkus simple project

The goal is to use purely official tekton tasks and just configure the pipeline.

Pipeline design

The pipeline consists of these steps:

1. Clone git repo (git-clone)
2. Compile, build and push image to repository (maven task + quarkus container plugin)

Prerequisites

Minikube

Install Minikube: https://kubernetes.io/docs/tasks/tools/install-minikube/

Mac:

brew install minikube

Start minikube

minikube start

Add registry helpers

minikube addons enable registry && minikube addons enable registry-aliases

Tekton

Install Tekton: https://github.com/tektoncd/pipeline/blob/master/docs/install.md

kubectl apply --filename https://storage.googleapis.com/tekton-releases/pipeline/latest/release.yaml

Optionally install Tekton CLI: https://github.com/tektoncd/cli

Tekton official tasks

# git-clone task
kubectl apply -f https://raw.githubusercontent.com/tektoncd/catalog/master/task/git-clone/0.2/git-clone.yaml
# maven task
kubectl apply -f https://raw.githubusercontent.com/tektoncd/catalog/master/task/maven/0.2/maven.yaml

Pipeline Deploy

Apply all pipeline yamls.

1. persistent-volume-claims.yaml - contains volumes for pipeline
2. pipeline.yaml - build pipeline

kubectl apply -f pipeline

Pipeline Run

via Tekton CLI:

tkn pipeline start build-pipeline \
 --param gitUrl='https://github.com/lkrzyzanek/quarkus-tekton-pipeline-example.git' \
 --param gitRevision='master' \
 --param imageGroup='test' \
 --param imageName='getting-started' \
 --workspace name=shared-workspace,claimName=shared-workspace \
 --workspace name=maven-settings,emptyDir="" \
 --showlog

and wait for the output like

PipelineRun started: build-pipeline-run-h7p2n
Waiting for logs to be available...

It ends classic maven output and these two lines specify where the image was pushed

[build-push-image : mvn-goals] [INFO] [io.quarkus.container.image.jib.deployment.JibProcessor] Container entrypoint set to [java, -Djava.util.logging.manager=org.jboss.logmanager.LogManager, -cp, /app/resources:/app/classes:/app/libs/*, io.quarkus.runner.GeneratedMain]

You can also check details via:

tkn pipelinerun describe build-pipeline-run-h7p2n

Deploy app

kubectl create deployment getting-started --image=example.com/test/getting-started:1.0-SNAPSHOT
kubectl expose deployment getting-started --type=LoadBalancer --port=8080
minikube service getting-started

try the rest endpoint: http://127.0.0.1:53430/hello
