Start by installing Jenkins on a machine or a server. You can follow the official Jenkins installation guide for more details on how to install it.
Once Jenkins is installed, go to the Manage Jenkins section and install the Kubernetes plugin. This plugin allows Jenkins to interact with Kubernetes and manage containers.
In Jenkins, go to the Global Configuration section and add your Kubernetes configuration. This includes specifying the Kubernetes server URL, credentials, and other settings. Make sure you have the necessary permissions to access the Kubernetes cluster.
Create a Jenkins pipeline or a job to define your build and deployment process. You can write the pipeline script using the Jenkinsfile syntax or use the Jenkins GUI to create a pipeline visually.
In the pipeline script or configuration, specify the Kubernetes agent to run the pipeline steps. This tells Jenkins to spin up a Kubernetes Pod as an agent to execute the build and deployment steps.
Within the pipeline, define the Kubernetes deployment YAML file or use dedicated Kubernetes Jenkins plugins to handle deployment actions. This includes defining container images, replicas, labels, and other deployment settings.
Save and run the Jenkins pipeline to trigger the build and deployment process. Jenkins will spin up a Kubernetes Pod as an agent, fetch the source code, build the application, and deploy it to the Kubernetes cluster according to the defined deployment configuration.
Jenkins can continuously monitor the Kubernetes cluster and perform health checks, auto-scaling, and rolling updates based on your configuration. You can also use Jenkins to manage other Kubernetes resources like services, secrets, and configurations.
By following the above steps, you can leverage the power of Jenkins to build and deploy applications to a Kubernetes cluster efficientl
