lightwalletd/kubernetes/tekton

Tekton CI

The configurations in this directory are for automating lightwalletd operations using Tekton.

Currently new tags will trigger a docker build and push to https://hub.docker.com/r/electriccoinco/lightwalletd

Testing

Requirements

• kind installed
• docker installed
• A Docker Hub account (create a new one if you want, its free!)

Setup

Log into Docker Hub

Just run the command:

docker login

This creates a config.json file that we're going to send to tekton and contains your Docker Hub password!

More info: https://github.com/tektoncd/pipeline/blob/master/docs/auth.md

Create a kind cluster

kind create cluster --name tekton-testing-zcashd_exporter

Create a Kubernetes secret containing your Docker hub creds

kubectl create secret generic dockerhub-creds \
 --from-file=.dockerconfigjson=~/.docker/config.json \
 --type=kubernetes.io/dockerconfigjson

Create a service account to use those creds

kubectl apply -f serviceaccount.yml

Install Tekton

kubectl apply -f https://storage.googleapis.com/tekton-releases/pipeline/previous/v0.15.2/release.yaml
kubectl apply -f https://github.com/tektoncd/dashboard/releases/download/v0.9.0/tekton-dashboard-release.yaml

Install the Tekton Catalog tasks

These are predefined tasks from the tektoncd/catalog collection on github.

kubectl apply -f https://raw.githubusercontent.com/tektoncd/catalog/master/task/git-clone/0.2/git-clone.yaml
kubectl apply -f https://raw.githubusercontent.com/tektoncd/catalog/master/task/kaniko/0.1/kaniko.yaml

Create the pipeline

kubectl apply -f pipeline.yml

Edit the PipelineRun

This object holds all of your pipeline instance parameters.

You must edit (unless somehow you got access to my Docker Hub account)
Change electriccoinco to your Docker Hub account name.

    - name: dockerHubRepo
      value: electriccoinco/lightwalletd

You can also change the gitTag and gitRepositoryURL values if you want to try building off some other commit, or you fork the code to your own repo.

Run the pipeline!

You can do this as many times as you want, each one will create a new pipelinerun.

kubectl create -f pipelinerun.yml

View the dashboard for status

Forward a port from inside the kubernetes cluster to your laptop.

kubectl --namespace tekton-pipelines port-forward svc/tekton-dashboard 9097:9097 &

The browse to http://localhost:9097/#/namespaces/default/pipelineruns
