Step 1

Create a basic application that you want to deploy using pipeline. We have created a go server, main.go and go.mod.

Step 2

Now create a Dockerfile that will build the image and test it locally.

Step 3

Create a new Jenkins image so that docker can work in it.

FROM jenkins/jenkins:lts
USER root
RUN apt-get update
RUN curl -sSL https://get.docker.com/ | sh

And run this image using the command

sudo docker run -p 8080:8080 -p 50000:50000 -v /var/run/docker.sock:/var/run/docker.sock go/jenkins:latest

go/jenkins:latest is the name of the built image in our case.

Step 4

Setup Jenkins dashboard

Step 5

Create a new Pipeline project in Jenkins and enable GitSCM polling to integrate with GitHub webhooks. Add the Jenkinsfile to the script to create the pipeline steps and initialize the pipeline.

Step 6

Expose your localhost port 8080 which is running Jenkins to the internet using ngrok. ''' ngrok http 8080 ''' Verify the link provided if it is now accessible.

Step 7

Go to your GitHub project of your application and in settings add a new webhook with the ngrok url and add '/github-webhook/' at the end of the url, enable webhook to run on pushes, PRs and commits.

Step 8

Now startup minikube and install ArgoCD using the official documentation and create a new app that links to your other repo which will include all k8s config yaml files for GitOps.

Step 9

Simply expose your service using the minikube official documentation. ''' minikube service pipeline-service --url '''
