tekton-cnb

The project aims to demonstrate auxiliary staging mechanism for CloudFoundry applications using Tekton and Cloud Native Buildpacks(CNB).

Requirements:

• k8s cluster(v1.15+)

Install Tekton:

• Install tekton on your k8s cluster by following instructions here.

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

• You can optionally install tekton dashboard and cli.

• In order to access tekton Dashboard run the following command and access it on http://localhost:9097:

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

Setup CNB builds:

Clone the repo and install the tekton task which builds the app image using CNB:

kubectl create namespace build
kubectl apply -f task/buildpacks-v3.yaml

Build App Image:

• Create a secret and a service account which will store your docker registry credentials:

kubectl apply -f auth/secret.yaml
kubectl apply -f auth/serviceaccount.yaml

• Replace the appropriate values for serviceAccountName, git repo of your app, and outputs.resources.image.url to be built in taskruns/build-run.yaml and run following command to build and push app image to the specificed docker registry.

kubectl apply -f taskruns/build-run.yaml

Deploy App:

• In order to deploy the app container image you need to have a running CF deployment like kubecf.

• Install the tekton task to deploy app on CF:

kubectl create namespace deploy
kubectl apply -f tasks/deploy.yaml

• Substibute the appropriate param values in taskruns/deploy-run.yaml and deploy the app container image by using following command:

kubectl apply -f taskruns/deploy-run.yaml
