In a few minutes, you will have the following components up and running in the tekton-pipelines of your Kubernetes cluster:
-
Tekton v0.10.1
-
Kube Stats Metric v1.4.0
-
Elastic Stack 7.5.2, Elasticsearch / Kibana / Beats (filebeat and metricbeat) deployed using the official Elastic Helm Charts
By default, some TaskRuns and PipelineRuns from the official Tekton repositories are executed in the tutorials namespace to generate data.
TL;DR
# Insall all resources and run TaskRuns/PipelineRuns examples
./scripts/set-up-env.sh
# wait for Forwarding from [::1]:5601 -> 5601
open http://localhost:5601/-
Local Kubernetes environment (Docker for Desktop, Minikube…)
-
Helm v2.16+ installed
NOTE: for now this tutorial is only tested on Docker Desktop for Mac
Figure 1. tekton example with Kaniko (Dockerfile in git → Docker image pushed to Dockerhub)
The samples folder contains several examples using Tekton Tasks and Pipelines.
The Elastic components (Elasticsearch, Beats and Kibana) are deployed to the Kubernetes cluster to collect the logs and metrics from the pods deployed by Tekton.
The Tekton components deployed are the official ones. There is no need to update those components to monitor them using the Elastic Stack.
-
samples/01-hello-worldcontains a Task and a TaskRun to print Hello World -
samples/02-kaniko-push-dockerhubcontains a Task and a TaskRun to build and push a Docker image from a git repository using Kaniko
# make sure you are using the right k8s context
$ kubectl config current-context
docker-for-desktop
# install all the components
$ ./scripts/set-up-env.sh initThen wait until the pods are running before starting the tutorials
# Check All Elastic and Tekton pods
$ kubectl get pods -w -n tekton-pipelines
NAME READY STATUS RESTARTS AGE
tekton-pipelines-controller-77f74f5bcf-rbj8s 1/1 Running 0 1m
tekton-pipelines-webhook-f76c97965-5xkxq 1/1 Running 0 1mWhen the set-up is done, you should have a Kibana pod up and running:
# Check Elastic pods
$ kubectl get pods -n tekton-pipelines
NAME READY STATUS RESTARTS AGE
elasticsearch-7bf6cd96cd-r6llt 1/1 Running 0 4m
filebeat-5lrwg 1/1 Running 0 4m

kube-state-metrics-b8845b4d7-ch9v7 1/1 Running 0 4m
metricbeat-zctb6 1/1 Running 0 4mThen you can access to the Kibana Infrastructure app:
Check the Tekton Pipeline Controller logs to make sure everything is OK
CONGRATS you are now ready to start the tutorials!
To check the Tekton metrics
kubectl port-forward deployment/tekton-pipelines-controller 9090 --namespace tekton-pipelines
