To integrate Minikube with Jenkins, follow these steps:

  1. Install the necessary Jenkins plugins: Kubernetes plugin: This plugin allows Jenkins to dynamically provision a build agent in a Kubernetes cluster. Docker Pipeline plugin: This plugin provides a Docker DSL for defining Docker-based Jenkins pipelines.
  2. Install and configure Minikube: Install Minikube using the installation instructions specific to your operating system. Start Minikube and ensure that it is running properly by executing the minikube start command in your terminal.
  3. Configure Jenkins credentials: Create Kubernetes credentials in Jenkins by navigating to "Manage Jenkins" -> "Manage Credentials" -> "Jenkins" -> "Global credentials" -> "Add Credentials". Enter your Kubernetes cluster credentials, such as the kubeconfig file path and the cluster certificate authority data.
  4. Configure the Kubernetes Cloud in Jenkins: Go to "Manage Jenkins" -> "Configure System" -> "Cloud" section -> "Add a new Cloud" -> "Kubernetes". Enter a name for the cloud configuration. Fill in the Kubernetes URL field with the Minikube cluster API server URL (usually https://
  5. Create a Jenkins Pipeline job: Create a new Jenkins Pipeline job by clicking on "New Item" -> "Enter an item name" -> "Pipeline" -> "OK". In the Pipeline definition, select the "Pipeline script from SCM" option. Specify the SCM details, such as the Git repository URL and the Jenkinsfile location. Save the job configuration.
  6. Define the Jenkins pipeline: Create a Jenkinsfile in your Git repository that defines the Jenkins pipeline steps. Use the Kubernetes plugin syntax to define the Kubernetes Pod template and container specifications. Configure the Jenkins pipeline stages to build, test, and deploy your application to Minikube. Use the Minikube cluster for the Kubernetes agent to run the pipeline steps. Commit and push the Jenkinsfile to your Git repository.
  7. Run the Jenkins pipeline: Run the Jenkins job by clicking on "Build Now" or wait for any configured triggers to trigger the build. Jenkins will start a Kubernetes Pod as a dynamic build agent, and the pipeline defined in the Jenkinsfile will be executed against the Minikube cluster.


By following these steps, you can integrate Minikube with Jenkins and run your build, test, and deployment processes in a Kubernetes cluster.

Integrating Minikube with Jenkins allows you to run your Jenkins builds in a Kubernetes environment that is local and isolated. By following the steps outlined below, you can set up Minikube as a Kubernetes cluster for Jenkins to dynamically provision build agents and execute pipelines:

  1. Install Minikube: Ensure you have Minikube installed on your system. You can refer to the Minikube documentation for installation instructions specific to your operating system.
  2. Start Minikube: Start Minikube by running the command minikube start. This command will boot up a local Kubernetes cluster using Minikube.
  3. Install Jenkins plugins: Make sure you have the necessary Jenkins plugins installed: Kubernetes plugin: This plugin allows Jenkins to interact with a Kubernetes cluster to dynamically provision build agents. Docker Pipeline plugin: This plugin provides Docker-related functionality for defining Jenkins pipelines.
  4. Configure Kubernetes credentials in Jenkins: Navigate to Jenkins and go to "Manage Jenkins" > "Manage Credentials" > "Jenkins" > "Global credentials" > "Add Credentials". Add Kubernetes credentials, including the kubeconfig file path and the cluster certificate authority data.
  5. Set up Kubernetes Cloud in Jenkins: Go to "Manage Jenkins" > "Configure System" and scroll down to the "Cloud" section. Add a new Kubernetes cloud configuration with the Minikube cluster API server URL as the Kubernetes URL.
  6. Create a Jenkins Pipeline job: Create a new Jenkins Pipeline job by clicking on "New Item", selecting "Pipeline", and providing a name for the job. In the Pipeline configuration, select "Pipeline script from SCM" and specify the Git repository and Jenkinsfile location.
  7. Define the Jenkins Pipeline: Create a Jenkinsfile in your Git repository that defines the pipeline steps. Utilize the Kubernetes plugin syntax to specify the Kubernetes Pod template and container configurations. Configure pipeline stages for building, testing, and deploying your application to Minikube.
  8. Run the Jenkins Pipeline: Trigger the Jenkins job by clicking on "Build Now" or based on any configured triggers in your pipeline. Jenkins will initiate a Kubernetes Pod as a build agent and execute the defined pipeline against the Minikube cluster.


By following these steps, you can seamlessly integrate Minikube with Jenkins and leverage the benefits of a Kubernetes environment for your CI/CD workflows.
