Deploying a DevOps project in Kubernetes using Helm-Chart involves creating and managing Kubernetes applications with Helm’s package manager. This process simplifies the deployment, scaling, and management of containerized applications. Helm charts package Kubernetes resources and configurations, enabling repeatable deployments and easy updates. The process includes defining charts, configuring values, and utilizing Helm commands to deploy, upgrade, or rollback applications, ensuring consistent and efficient DevOps workflows.

STEP 1: GITHUB Source code in Private Repo

GIT_TOKEN :your Git-hub token

STEP 2: Create a TWO EC2 SERVER ( One for Jenkins & Another for Sonarqube )

PRE-REQUIREDSITE

· In Jenkins Server, Install GIT, JAVA, JENKINS, NPM, NODEJS , DOCKER, KOPS, KUBECTL, HELM etc

· In sonarqube server, install docker & docker compose. Soner is run as a container by writting a docker compose file

STEP 3: In jenkins server, Login to jenkins dashboard and create one pipeline job, and also

Generated Token configure in the jenkins credential section. To access the GITHUB private repoistory for source code

Dashboard > Manage jenkins >Credentials >System >Global Credential >

In pipeline, select Job(Rocket-pipeline-project ) and write a jenkins file for SCM Checkout from git reposistory to jenkins pipeline

Here Declaritive pipeline script written for jenkins file SCM CHECKOUT.

Install Git in Server and also install git plugin jenkins dashboard

Dashboard > Rocket-pipeline-project > Configuration

Click Build Now

1st stage runned successfully.

STEP 4: Install the NPM & Nodejs in jenkins server and write a jenkins file npm install and build it

1st & 2nd stages run successfully.

Install the DOCKER to build package into docker image

Jenkins pipeline syntex

Stage view (output)

In credential section, Store the DOCKERHUB Password as a Secret text(to access dockerhub)

Also provide permission for docker deamon chmod 777 /var/run/docker.sock

Install Kops & kubectl to create k8s cluster

Cd .docker (move docker config.json ,

create docker directory in opt path and move this config.json)

Copy the .kube file and save as txt doc and upload in k8s credential section in jenkins server

Check the connectivity of the k8s cluster. (test connection)

Reqired permission for path /opt/docker/config.json (chmod 777 /opt/docker/config.json)

Build failed due to Permission denied. (/opt/docker/config.json)
