Kubernetes Build and deploy with flux2+helm+tekton+kaniko

PART 1: tekton

First, we start with the installation of the required components that we will be using.

Install Tekton Build tools

1. https://github.com/tektoncd/pipeline/blob/master/docs/install.md#installing-tekton-pipelines-on-kubernetes
2. go to this URL to get the latest release of tekton pipelines.

Apply kubectl get po -n tekton-pipelines to check all the components are running

Install Tekton Dashboard

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

it provides a nice interface for watching the pipelines and re-running also. It also comes with a command-line tool you can use the same tool to run your pipeline resources please go through the official documentation for more info.

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

install tekton triggers it helps to create webhooks for build and push jobs

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

please go through the documentation for installing flux in your cluster

Installation - Flux | GitOps Toolkit

you should check all the components running before we bump into to next part.

Configuring Tekton For creating and publishing images

first, we need the required creds to push the docker image

kubectl create secret docker-registry regcred \
                    --docker-server=https://index.docker.io/v1/ \
                    --docker-username=<your-name> \
                    --docker-password=<your-pword> \
                    --docker-email=<your-email>

Github secret

apiVersion: v1
kind: Secret
metadata:
  name: github-secrets
type: Opaque
data:
  token: github_personal_access_token_secret

Service account to push to docker hub

apiVersion: v1
kind: ServiceAccount
metadata:
name: dockerhub-serviceaccount
secrets:
- name: regcred

Now let's Move on to create the pipelines and tasks

first, we will create two pipeline resources to handle our input and output.

- -
apiVersion: tekton.dev/v1alpha1
kind: PipelineResource
metadata:
name: build-image-via-pipeline
annotations:
fluxcd.io/automated: "true"
spec:
type: git
params:
- name: revision
value: master
- name: url
value: https://github.com/btwseeu78/demologinapp.git
…
- -
apiVersion: tekton.dev/v1alpha1
kind: PipelineResource
metadata:
name: push-image-via-pipeline
annotations:
fluxcd.io/automated: "true"
spec:
type: image
params:
- name: url
value: linuxarpan/kanikotesting:v5
…

The task to actually provide params and using resources

apiVersion: tekton.dev/v1beta1
kind: Task
metadata:
name: build-and-push-docker-image
annotations:
fluxcd.io/automated: "false"
spec:
params:
- name: pathToDockerFile
type: string
description: The Path To Docker File
default: $(resources.inputs.docker-source.path)/Dockerfile
- name: pathToContext
type: string
description: the build context used by kaniko
default: $(resources.inputs.docker-source.path)
resources:
inputs:
- name: docker-source
type: git
outputs:
- name: builtImage
type: image
steps:
- name: build-and-push
image: gcr.io/kaniko-project/executor:latest
args:
- - dockerfile=$(params.pathToDockerFile)
- - destination=$(resources.outputs.builtImage.url)
- - context=$(params.pathToContext)
volumeMounts:
- name: kaniko-secret
mountPath: "/kaniko/.docker/"
volumes:
- name: kaniko-secret
secret:
secretName: regcred
items:
- key: .dockerconfigjson
path: config.json

create a runner to run the task

apiVersion: tekton.dev/v1beta1
kind: TaskRun
metadata:
name: build-image-from-git-source
annotations:
fluxcd.io/automated: "false"
spec:
serviceAccountName: dockerhub-serviceaccount
taskref:
name: build-and-push-docker-image
params:
- name: pathToDockerFile
value: Dockerfile
resources:
inputs:
- name: docker-source
resourceRef:
name: build-image-via-pipeline
outputs:
- name: builtImage
resourceRef:
name: push-image-via-pipeline

Output

It's still beta just published to help someone if they want to start there are multiple ways to do this . I will update the cos and also add more explanation regarding all the components. In much detail also add flux and other tools like helm to create a nice ecosystem. stay tuned and please comment ask questions or suggestions I'm still new to this it will hem me learn a lot.

The indentation is kind of messed of so please go through the files in this repo they cover the YAML for task and resources.
